The <a href=\"https:\/\/thenextweb.com\/news\/jbl-l82-classic-review-these-retro-speakers-offer-modern-acoustics\">JBL L82 Classic<\/a> paired a retro aesthetic with acoustics that emphasized an expansive soundstage, while the <a href=\"https:\/\/thenextweb.com\/news\/jbl-hdi-1600-review\">HDI-1600<\/a> was a more modern take on speaker design with a deep horn\/waveguide for focused, sharp imaging.<\/p>\n<p>Well, what if you want both a retro design <em>and<\/em> a horn-type sound? JBL has a hi-fi speaker for you too: the $2,000 JBL 4309.<\/p>\n<p>Mercifully, unlike so many speakers appealing to retro aesthetics and nostalgia, the 4309 are still solid examples of modern acoustic design. While they aren\u2019t perfect, the speakers maintain JBL\u2018s neutral approach to speaker design with an impeccable spatial presentation.<\/p>\n<p>If you\u2019ve read my review of the <a href=\"https:\/\/thenextweb.com\/news\/jbl-hdi-1600-review\">JBL HDI-1600<\/a>, the 4309 sounds a <em>lot<\/em> like it. I didn\u2019t get to hear the speakers side-by-side, but having heard them both against my longtime reference speaker \u2014 the <a href=\"https:\/\/thenextweb.com\/news\/review-focals-chora-806-is-a-luxury-speaker-at-a-heck-of-a-price\">Focal Chora 806<\/a> \u2014 it\u2019s clear the speakers are more similar than different.<\/p>\n<p>This shouldn\u2019t be too surprising. The speakers share acoustic philosophies, use an identical tweeter (more specifically, a <a href=\"https:\/\/en.wikipedia.org\/wiki\/Compression_driver\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">compression driver<\/a>), and implement similar <a href=\"https:\/\/thenextweb.com\/news\/what-the-heck-is-a-waveguide\">waveguides<\/a> that shape the sound for optimal spatial presentation. They both offer 6.5-inch woofers too. But most notably, they <em>measure<\/em> very similarly.<\/p>\n<p>If you happen to find yourself choosing between these two speakers, I\u2019d just choose whichever you think is prettiest. They are close enough in price (the HDI-1600 retails for $1,800) and performance I suspect they\u2019d be ranked similarly in a blind test. Only JBL, which conducts blind tests for its speakers, knows for sure which is \u2018better,\u2019 but the 4309<em> is<\/em> priced a little higher.<\/p>\n<p>I\u2019ll let you know which one <em>I<\/em> think sounds better later in this review. I know, I\u2019m such a tease.<\/p>\n<p><figure class=\"post-image post-mediaBleed aligncenter\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-full wp-image-1359541 js-lazy\" src=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/JBL-4309-2-of-3-1.jpg\" alt=\"JBL 4309\" width=\"1640\" height=\"2187\" sizes=\"(max-width: 1640px) 100vw, 1640px\" data-srcset=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/JBL-4309-2-of-3-1.jpg 1640w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/JBL-4309-2-of-3-1-157x210.jpg 157w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/JBL-4309-2-of-3-1-202x270.jpg 202w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/JBL-4309-2-of-3-1-101x135.jpg 101w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/JBL-4309-2-of-3-1-796x1061.jpg 796w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/JBL-4309-2-of-3-1-1592x2123.jpg 1592w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/JBL-4309-2-of-3-1-1122x1496.jpg 1122w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/JBL-4309-2-of-3-1-840x1120.jpg 840w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/JBL-4309-2-of-3-1-687x916.jpg 687w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/JBL-4309-2-of-3-1-414x552.jpg 414w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/JBL-4309-2-of-3-1-354x472.jpg 354w\"><noscript><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-full wp-image-1359541\" src=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/JBL-4309-2-of-3-1.jpg\" alt=\"JBL 4309\" width=\"1640\" height=\"2187\" srcset=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/JBL-4309-2-of-3-1.jpg 1640w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/JBL-4309-2-of-3-1-157x210.jpg 157w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/JBL-4309-2-of-3-1-202x270.jpg 202w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/JBL-4309-2-of-3-1-101x135.jpg 101w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/JBL-4309-2-of-3-1-796x1061.jpg 796w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/JBL-4309-2-of-3-1-1592x2123.jpg 1592w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/JBL-4309-2-of-3-1-1122x1496.jpg 1122w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/JBL-4309-2-of-3-1-840x1120.jpg 840w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/JBL-4309-2-of-3-1-687x916.jpg 687w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/JBL-4309-2-of-3-1-414x552.jpg 414w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/JBL-4309-2-of-3-1-354x472.jpg 354w\"><\/noscript><\/figure>\n<\/p>\n<p>I will say right away that I\u2019m immediately biased towards the 4309\u2019s retro aesthetics. What can I say? I live in Brooklyn, and it fits the vibe.<\/p>\n<p>Retro-ness aside, it also has a blue baffle and grille (there\u2019s a <a href=\"https:\/\/www.jblsynthesis.com\/products\/loudspeakers\/series\/studio-monitors\/4309-.html?dwvar_4309-_color=Black-GLOBAL-Current\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">black version<\/a> too) and I\u2019m a sucker for blue speakers. There should really be more of them.<\/p>\n<p>The speakers feel solidly built, and I like how the grille only covers the more vulnerable woofer. Usually, grilles are detrimental to sound quality, but I could not hear the difference with the 4309. The compression driver is safely tucked away at the rear of the horn, so it doesn\u2019t need the added protection.<\/p>\n<p>As a bit of a throwback bonus, the 4309s also include a high-frequency adjustment knob that is rarely found on modern speakers. It only has a range of +\/- 1 dB, but that can be the difference between a speaker sounding too bright or too dull in some homes. You could of course always apply EQ elsewhere, but it\u2019s nice to have dedicated controls on the speakers.<\/p>\n<p>A few words about my review style: I try not to shower&nbsp;speakers with vague superlatives. There are plenty of other reviews for that. In my mind, what defines a good speaker isn\u2019t the presence of ineffable euphonic qualities, but rather an <em>absence<\/em> of audible flaws. In some ways, the better the speaker, the less I have to write about.<\/p>\n<p>I also believe in the usefulness of speaker measurements and prefer to test products that seemingly adhere to the best science we have on acoustics. That is, speakers with a flattish frequency response and smooth directivity. Not every speaker needs to be ruler flat, but unless there\u2019s a really good reason for deviating,&nbsp;<a href=\"https:\/\/www.notion.so\/The-Polk-Reserve-R200-is-an-absolute-steal-of-a-speaker-for-700-a-pair-4d58c98884e241828e971a411622f41a\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">research suggests<\/a> that speakers with these qualities are both the most accurate and the most likely to be enjoyed by listeners. That same research also tells us our tastes aren\u2019t as nearly as unique as people tend to assume.<\/p>\n<p>I always listen to a speaker before measuring when possible, but my listening notes tend to correlate <em>very<\/em> closely to measured data, so it makes sense to talk about them together.<\/p>\n<p>On that note, let\u2019s look at how the JBL 4309 performs when put through my test setup. The graph below is called a spinorama (also known as the CTA-2034A standard), so-called because one has to spin a speaker around to capture the sound at 70 different angles.<\/p>\n<p><figure class=\"post-image post-mediaBleed aligncenter\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-full wp-image-1359531 js-lazy\" src=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-Spin.png\" alt=\"JBL 4309 Spinorama\" width=\"1200\" height=\"996\" sizes=\"(max-width: 1200px) 100vw, 1200px\" data-srcset=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-Spin.png 1200w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-Spin-253x210.png 253w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-Spin-325x270.png 325w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-Spin-163x135.png 163w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-Spin-796x661.png 796w\"><noscript><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-full wp-image-1359531\" src=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-Spin.png\" alt=\"JBL 4309 Spinorama\" width=\"1200\" height=\"996\" srcset=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-Spin.png 1200w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-Spin-253x210.png 253w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-Spin-325x270.png 325w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-Spin-163x135.png 163w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-Spin-796x661.png 796w\"><\/noscript><\/figure>\n<\/p>\n<p>I explain what these lines mean and how they are calculated in the spinorama section of <a href=\"https:\/\/www.notion.so\/JBL-4309-measurement-review-Retro-gold-5225521e269a411199dd00727be6b0c1\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">my measurements guide<\/a>, but we can focus on a few key things here.<\/p>\n<p>There are two primary things that dictate a speaker\u2019s sound. There is the direct sound that travels in a line of sight from the speaker to your head. Then there is the sound the speaker radiates in all directions, which gets reflected off your walls and eventually reaches your ears. You need good performance in both respects in order to achieve truly exceptional sound.<\/p>\n<p>Like most speakers following evidence-based design, the 4309\u2019s sound is overall, quite neutral and transparent. In a way, much of the following assessment is splitting hairs, but, well, that\u2019s just what audiophiles do.<\/p>\n<p>Let\u2019s evaluate the \u2018direct\u2019 sound first represented by the white (listening window) and green (on-axis) lines in the spin. I tend to focus on the listening window, as it\u2019s an average of a few measurements that more realistically represents how the speaker is likely to be perceived. Ideally, this would be a flattish line, especially between roughly 200 Hz to 10kHz. The 4309 is <em>mostly<\/em> flat, with a few notable colorations.<\/p>\n<p><figure class=\"post-image post-mediaBleed aligncenter\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-full wp-image-1359535 js-lazy\" src=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-lw.png\" alt width=\"1200\" height=\"876\" sizes=\"(max-width: 1200px) 100vw, 1200px\" data-srcset=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-lw.png 1200w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-lw-280x204.png 280w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-lw-370x270.png 370w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-lw-185x135.png 185w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-lw-796x581.png 796w\"><noscript><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-full wp-image-1359535\" src=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-lw.png\" alt width=\"1200\" height=\"876\" srcset=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-lw.png 1200w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-lw-280x204.png 280w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-lw-370x270.png 370w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-lw-185x135.png 185w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-lw-796x581.png 796w\"><\/noscript><\/figure>\n<\/p>\n<p>Like the HDI-1600, the 4309 does have a slightly emphasized bass. This isn\u2019t a bad thing in my eye, especially in bookshelf speakers, which almost never extend all the way into the sub-bass. That said, there is a solid amount of bass extension here, comfortably audible to about 40 Hz in room.<\/p>\n<p>On the other hand, the bass emphasis in the 100 Hz region means you probably won\u2019t want to keep the speaker <em>too<\/em> close to your front wall or corners (unless you\u2019re using EQ) lest the bass become truly excessive.<\/p>\n<p>The rest of the frequency range is nicely neutral. There\u2019s a bump around 1 kHz and a dip around 1.8 kHz \u2014 right in the middle of the midrange, but they are narrow enough that I did not find them to be highly audible (small dips don\u2019t tend to be very audible anyway). Your mileage may vary, and ideally, this flaw wouldn\u2019t be there, but sometimes deviations are less audible than they look.<\/p>\n<p>Next we can look at the purple line \u2014 that\u2019s the predicted in-room response. This weighs all 70 angles of the spinorama to predict how a speaker will perform in a typical living room setup. This should also look like a flattish line, except tilted downwards, and for the sake of the soundstage, it should roughly follow the shape of the listening window. (The PIR is almost always very similar to the blue \u2018early reflections\u2019 curve, so the former is often omitted from the spinorama).<\/p>\n<p><figure class=\"post-image post-mediaBleed aligncenter\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-full wp-image-1359536 js-lazy\" src=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-PIR.png\" alt width=\"1200\" height=\"876\" sizes=\"(max-width: 1200px) 100vw, 1200px\" data-srcset=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-PIR.png 1200w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-PIR-280x204.png 280w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-PIR-370x270.png 370w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-PIR-185x135.png 185w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-PIR-796x581.png 796w\"><noscript><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-full wp-image-1359536\" src=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-PIR.png\" alt width=\"1200\" height=\"876\" srcset=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-PIR.png 1200w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-PIR-280x204.png 280w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-PIR-370x270.png 370w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-PIR-185x135.png 185w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-PIR-796x581.png 796w\"><\/noscript><\/figure>\n<\/p>\n<p>Here we do <em>mostly<\/em> get that, except the messiness in the mids is more pronounced.

The main aspects of tonality that stood out to me were the slightly exaggerated bass and perhaps a slightly lean-ness around the lower mids. The lower mids are about a decibel or two below the upper mids and treble, which seemed to give the speaker\u2019s a \u2018dryer,\u2019 slightly cooler sound.

Remember, both the direct and reflected sound affect what we hear, and it\u2019s the relationship between the two that largely defines a speaker\u2019s soundstage performance. We want the reflected sound to closely match the direct sound. If it doesn\u2019t, not only will tonality be affected, but the soundstage will become muddy too.<\/p>\n<p>The blue line at the bottom of the spinorama, the \u2018directivity index\u2019 and \u2018early reflections directivity index\u2019 tells us about the speaker\u2019s directivity. Ideally these would be smooth rising lines, and here we almost get that \u2014 except for, again, those deviations between 1-2 kHz.<\/p>\n<p>However, one problem with the spinorama is that it doesn\u2019t separate horizontal and vertical directivity.

While there\u2019s no hard and fast rule for what constitutes \u2018wide\u2019 and \u2018narrow\u2019 directivity in a speaker, the JBL 4309, like the HDI-1600, trend a little towards the latter among bookshelf speakers I\u2019ve tested (by comparison, the JBL L82 and Focal Chora 806 are more on the \u2018wide\u2019 side).<\/p>\n<p>This is great if you want speakers that present instruments in a very precise manner, such that you could almost point to where exactly the sound is coming from with a laser. Which type of soundstage is <em>best<\/em> is largely a matter of taste and how the speaker interacts with your room and setup. I tend to prefer the more expansive presentation, but the 4309 is not crazy narrow, and I found it presented one of the most realistic spatial image of any speaker I\u2019ve tested.<\/p>\n<p>In terms of spatial presentation, I actually felt I enjoyed it a little more than the HDI-1600, and I think it measure a little better too. That, combined with my aesthetic preference for the retro model, means the 4309 is the speaker I\u2019d personally choose.<\/p>\n<p>While the vertical response is not as important, it can still color the sound. Two things I like to focus on are whether a speaker is sensitive to vertical positioning by measuring at a few degrees above and below the speaker. We can see that being up 10 degrees above or below the tweeter does not majorly affect the speaker\u2019s sound:<\/p>\n<p><figure class=\"post-image post-mediaBleed aligncenter\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-full wp-image-1359533 js-lazy\" src=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-vertical-10.png\" alt width=\"1200\" height=\"905\" sizes=\"(max-width: 1200px) 100vw, 1200px\" data-srcset=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-vertical-10.png 1200w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-vertical-10-278x210.png 278w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-vertical-10-358x270.png 358w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-vertical-10-179x135.png 179w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-vertical-10-796x600.png 796w\"><noscript><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-full wp-image-1359533\" src=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-vertical-10.png\" alt width=\"1200\" height=\"905\" srcset=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-vertical-10.png 1200w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-vertical-10-278x210.png 278w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-vertical-10-358x270.png 358w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-vertical-10-179x135.png 179w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/4309-vertical-10-796x600.png 796w\"><\/noscript><\/figure>\n<\/p>\n<p>Then I like to see how the estimated ceiling and floor reflections look:<\/p>\n<p><figure class=\"post-image post-mediaBleed aligncenter\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-full wp-image-1359534 js-lazy\" src=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/ER-Vertical.png\" alt width=\"1200\" height=\"864\" sizes=\"(max-width: 1200px) 100vw, 1200px\" data-srcset=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/ER-Vertical.png 1200w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/ER-Vertical-280x202.png 280w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/ER-Vertical-375x270.png 375w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/ER-Vertical-188x135.png 188w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/ER-Vertical-796x573.png 796w\"><noscript><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-full wp-image-1359534\" src=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/ER-Vertical.png\" alt width=\"1200\" height=\"864\" srcset=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/ER-Vertical.png 1200w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/ER-Vertical-280x202.png 280w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/ER-Vertical-375x270.png 375w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/ER-Vertical-188x135.png 188w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2021\/07\/ER-Vertical-796x573.png 796w\"><\/noscript><\/figure>\n<\/p>\n<p>Here\u2019s where we see the speaker\u2019s flaws, but vertical problems are present in the vast majority of speakers.
