Amazing review as always. A lot of reviewers hype these speakers to the moon. We are lucky to have you!

[@wegardfjeld3789]

Put them up vs Arendal 1723 THX. That's the price range this competes with and the Arendals are still better built. Qualio, Mofi ++ is out of its price range even if they try to tell you otherwise. Sorry SVS, but If you want to enter this competitive price pov it's not just about having a big base....

[@quikspecv4d]

I’ll be waiting for your 888 review

[@Clint_the_Audio-Photo_Guy]

I measured ours in room, 28" from the back wall, 40" from the side walls, and they were +15DB at 40hz! It overwhelmed the room as well as the mids and highs. Previously in that spot were Revel Salon 2's and they sounded great in literally the same position. Someone call Danny from GR Research, because these puppies need to be revoiced!

[@NosEL34]

Great job. I gotta say i love the look of these speakers. The compression graph was the one thing that made me grimace. Distortion data was outstanding. I think these would do well in a dedicated home theater or a well done dedicated listening space. With the treatment & DSP i could see people liking these if they gave 'em a chance. Not perfect but none are. I like that SVS tried something different. I also like them as a company & hope to see them keep moving forward.

[@wegardfjeld3789]

Arendal 1723 thx, half the price and better sound with a better building quality. They need to do way better or just avoid this price range

[@ErinsAudioCorner]

I appreciate that!

[@davidfuller581]

Well... this is fairly disappointing. LW and on-axis are both really rough, and directivity isn't good enough to allow for correcting without significant early reflection absorption. Might be OK in a purpose built HT room, but otherwise?

[@ErinsAudioCorner]

Smash!

[@mddawson1]

This speaker was on my short list to replace my 24 year old Vaf DC-X speakers. Ultimately it was the cost here in Australia that put me off (note $5000US is currently $7479AUD). After exchange rates, transport and importer and dealer charges, these list here at $11,499AUD. I think even SVS has acknowledged this is too much so are discounting them to $10,349AUD. So I have gone with the Arendal 1723 speakers for just under $7000AUD ($4499US). Going by this review, it seems I made the right choice.

[@parksinrecreation2886]

Thank you for the review, Erin, and thank you to SVS for loaning you the speakers! That's a commendable decision on their part. Even though the speakers aren't perfect and can improve in some areas, it shows me that they are willing to listen and make said improvements. And hey, nothing here says this is a bad speaker, so it might still be a great buy for myself and many others! We will just take into account the things you mentioned, is all. But I like that SVS is going for something new here. Going to give these some more thought. The way the handle bass kind of appeals to me honestly.

[@SuperMcgenius]

Wondering how many viewers understand the technical aspects of your reviews, years ago I would not, but I educated myself by reading books by Martin Colloms speaker design and Toole Floyd also papers on room acoustics. Note: I like your reviews and the considerable time spent doing them. 👍

[@JamesWilliams-gf8gm]

Honestly I think the SVS crowd will like the over done bass and these will sell well, It will thump. I bet the smaller tower measures better. That 2500hz peak would give me a moment of pause though.

[@Jeipr]

I thin the smaller of the towers its the one that will spind best for misoc specifically. True in the part pf the SvS Crowd; but they tend to be mpre Home theater oriented and this Towers speaks to their needs big time !

[@swllz]

Every speakers in this line has a tweeter crossover at 1.8Khz, tweeter should behave similarly in terms of distortion and radiation pattern, or 2500hz peak.

[@JamesWilliams-gf8gm]

@@swllz I was thinking more about the bass peak, but yes I agree with you.

[@dgregory4178]

So 3db is a peak?

[@shipsahoy1793]

@@dgregory4178 I believe he's referring to that 3dB of enhancement in the treble at the 102 dB SPL.. personally, I know that would sound annoying to me.. I don't even have to hear it, I can already imagine what it would sound like. Everyone else might not be so lucky. If you can't understand if you're interested in these based on the review but would like to demo them, you by all means should. $5k is a good chunk of change. The amplifier is going to be important too... those little Class D amps probably aren't going to cut it. I would assume that anybody looking to buy speakers this size probably want to go loud with quality sound. $5k is a low amount or a "budget" amount for something like this, so I'd expect some disappointment. 😉

[@kevind4061]

Yes, finally, a quality review of SVS's best; I am glad its coming from @ErinsAudioCorner! I've only seen reviews for the Titan.

[@swllz]

Anther great review. $5k to buy a scooped and shooty midrange is not a good deal for consumers. Some people will like the bassy speakers. Looking at impedence curve, anyone with AVR's cost $4000 or less should not expect to properly drive these speakers. Wonder if or when the bookshelf version be measured. Every speakers in this line has a tweeter crossover at 1.8Khz, tweeter should behave similarly in terms of distortion and radiation pattern.

[@Artcore103]

"anyone with AVR's cost $4000 or less should not expect to properly drive these speakers." Incorrect assessment. This should read something like, for example, "anyone with AVR's (or amplifiers) rated at less than 200w into 4 ohms, and not rated to handle thx spec 4 ohm loads (3.2 ohm), or 2 ohms, should not expect to properly drive these speakers." The correction is because price is UTTERLY IRRELEVANT, the only thing that matters is the specs... I mean, the ACTUAL specs, not necessarily claimed specs, but the measured accurate specs of the equipment. You could drive these speakers EXTREMELY WELL with zero issues, to their limits, for under 1000 dollars. This is not about money but specs. AVR's are stupid anyway, and there's not many that are truly good, powerful, low impedance rated power amplifiers. They should sell AVR's with no power amps at all, it's just a glorified surround processor and input/output switcher, and preamp, dac, phono preamp, etc. But you could get a hypex ncore amp, or even a tripath design, or a number of amps for under a grand - even under 500 dollars - that can MORE than drive these speakers to their absolute limits with no issues whatsoever. There is almost ZERO correlation between price and quality, or price and power output level, when it comes to modern amplifiers. Obviously if we're talking super budget, under a couple hundred bucks, then there is a correlation. But beyond a certain ultra-budget level, there is zero correlation... there is only consumer knowledge or lack thereof, and product selection. Stop buying dumb overpriced AVR's (by overpriced I mean way under 4k.... 2k is overpriced), and buy REAL power amps, that aren't stupid audiophile brands with the audiophile tax, but are simply objectively awesome... like a hypex amp.

I just bought and am currently packing up and returning these speakers. I wish I would have seen your review a few weeks ago. I wouldn’t have ordered them. Shouty and harsh, those are the words that come to mind from my listening session. Honestly in my gigantic room I didn’t find the bass too much at all, however I didn’t find it to be musical. Thanks for the extensive work you do on these reviews.

Might I ask what acoustic treatment you have in your room?

Did you come to this conclusion before or after watching this review?

[@bberger2]

@@ProudPapaKYI have a large 25x25 room with some low slung furniture and thick wool carpets with padding. I sit in a golden triangle scenario (9.5 feet between speakers) and 9.5 feet to listening position. The wall behind me and to the sides is about 15 feet away. I have had this listening room for 6 years and used lots of equipment (including speakers) here, soon know it well as a reference. The plan with SVS were to replace my Focal Aria 948s. It is possible that I could, as @erin mentions but some EQ equipment and add some dedicated room treatment to improve the SVS in this space. But I couldn’t find anything redeeming about them that would make we want to travel down that road.

[@bearclaw5115]

Great job Erin! I suspected these would be too much for my small theater and know I can see why that is indeed true. It also looks like they crossed over to the tweeter too early with this design. For this kind of money they should have dialed in the driver integration much tighter.

[@weeooh1]

Excellent review Erin, thanks. Imagine if someone sent these speakers to Danny Richie to tweak or fix. 😆

[@FOH3663]

He'd examine and share the bottleneck elements that limit the performance in the signal path. Every mfr of this type of loudspeaker build to a price point. Designing, building, and bringing a widely available loudspeaker to market, involves serious juggling of comprimises. Danny simply points out those comprimises.

[@MichaelBeeny]

I moment I saw the multitude of drivers I just knew integrating all these would be an issue, the least of which would be low impedances. In days gone past driver were available in a number of different impedances. These days it's mostly just 8 ohms with a few at 4 ohms. You just know you are walking into issues. The idea is good, but in the real world a nightmare, as this company has found but not solved.

[@willbrink]

Great info per usual. Seen a few people get them and dislike them, but I noticed they were trying to drive them with lower power amplification and or, close the walls. Personally, I'd have interest in them if I had a large room and they were for more HT than music. Otherwise, meh. From a strictly value POV, they're a good deal.

Erin, I love what you do and appreciate the service you perform for audiophiles like us. I wonder how the Ultra Evolution Titan would measure since it has smaller bass and midrange drivers. Presumably, it wouldn't have as much of a lower frequency boost and may be more flexible with room placement, but I'm particularly curious how the different midrange drivers would perform.

I just mentioned that another reviewer contacted SVS and they said the anomalies in the frequency response measurements were done on purpose, based on listening tests. The reviewer I am talking about is extremely well known, and he gave the Titan speaker (slightly smaller than this one, but very similar) rave reviews, and no he doesn't give rave reviews to every speaker. However some reviewers only tend to review stuff that they think is somewhat decent, given the large number of good products out there. This particular reviewer had to purchase the Titan's with his own money, because SVS would not send him one due his channel giving a snub of one SVS's other speakers (I believe it was a subwoofer).

Look very cool, unfortunately the performance seems off for the price. Arendal 1723 THX, Kef R series, Ascend ELX, Revel F208, I could keep going. Its in territory where the on axis performance is simply not acceptable at its price. Quite unfortunate. If raw output and low distortion is needed and nothing else this seems ok, although that compression spike looks rough.

[@psyphonyxaudio]

Thanks for the thorough review. Seems like the arendal 1723 towers still are the best bang for buck tower in the 4-5k bracket

[@FOH3663]

An apparently brutal load aligned with that ~70hz boost. So, ... I suspect the greater and more robust the current capability of the amplifier, the more that boost is fully realized in output. It's worth noting the woofers must have adequately designed thermal attributes, as the Klippel compression measurements reveal little problem in that broad ~70hz range.

So, I drove down to San Antonio for the SVS Happy Hour last Thursday. On Friday, I went back and listened to the pinnacles, and I compared them, A/B..C, to the Focal Aria Evo X no 3, and the B&W 702 S2 ( I think). I was really taken with the Focals. Any chance you could review the Evo X no.3 or no.4? I haven’t seen a single review of the no.4 anywhere.

[@raananberger6830]

I was listening to your review through my Focal Chora 816, and it was hard not to notice that the tweeters looks identical. It is also very noticeable that the cabinet design and shape resemble Focal's high end series like Kanta and Sopra (the main difference I see is that the SVS are back ported while the Focal are front ported). Do you think that there is some kind on imitations between the firms? How is this speaker in comparison to, lets say, Focal's Kanta towers?

[@michaelrobinson9643]

Erin. how do you produce an acoustically invisible speaker today without adding your own "voicing" (which I call error)? Soundstage - breadth and depth, absolute detailed nuance of fine sounds and deep extension. Remove the room which should be managed on its own... and what are the options for speaker builders? Is this a market differentiating for sake of it and do you believe the technological moves forward are realising effective improvements in acoustic accuracy and quality for the $ spent? I do think in bass regions there is a LOT of improvement that can be achieved due to the sheer power and energy required to bend Hoffman's Law - and we are observing some of that. What about above that range though? DSP like Trinnov wave forming or general room EQ will clean out most speaker "voicing" efforts (yet never without consequence) and so for all SVS statements that these are for everyone, they really are purposed with design direction that suits certain listening and positioning.

[@iluvsweaterpuppets9166]

Hi Erin thanks for sharing your thoughts on this particular speaker. A good deep dive into its sonic character. The only thing I felt missing at least for me is what does the speaker actually sound like? Or more specifically what speakers does it bring to mind while listening to them. I currently own a pair of OG Klipsch rp 600m unmodified etc and they are fun. You have to acclimate yourself to them, especially how hot the tweeter is. I have them pointed straight at the rear wall and sit about 8ft away from them. They are 61/2 to 8ft apart and 3ft from the back wall. Amp is a oldie but Goldie adcom GFA 5800 with the early Nelson Pass circuit topology and it has PLENTY of juice for pretty much anything. I'm curious as whether these speakers have a sound signature similar to Sonus Faber, Focal, etc. What do they sound like???

[@ErinsAudioCorner]

I did describe the sound. 🤷‍♂️

[@iluvsweaterpuppets9166]

Yes in relative terms. I understand the analysis of the data you provided, what I am looking for is how does it compare to speakers x and y. You did that with the Mofi speakers in reference to the Kefs etc. I was looking for something similar to that. No problems and thanks for the data points.

[@xTremeSequences]

I can tell you I really like the sound a lot. Nothing is shouty in my room. The bass is very controlled and can go as deep as the music calls for. Room treatment made all the difference .I'm in a family room open to the dining and kitchen. 19' wide by 30' deep. I thought about sending them back and trying the Arendals but I really like the sound.

[@iluvsweaterpuppets9166]

​@@sanonmarsFor the price, you would expect better than this.

[@Xmvw2X]

I wonder if they could have run a slightly smaller mid, crossed a little higher, and could have handled the off axis response without compromising the low end, kind of depends on how high the woofers can go. For a speaker that kind of seems intended to get loud, crossing so low on the tweeter seems an odd choice. There certainly are some nice tweeters that will do sub 2kHz fine for frequency response, but you can never cheat physics and the need to physically move a volume of air. At the price point, they have the luxury to step to a 4-way setup and run a 2" to 3" something if they really wanted to stay with the 5.25" midrange. They might have been able to push the bigger drivers larger too, say a 6.5" and a 10" instead. 4-way can offer this luxury. But a 3-way is often a really good physics aligned combo at 1", 5.25", and 8" to 10" or technically even a 12" if you want and the mid is a high excursion driver.

[@dylanmitchell3978]

Awesome I was hoping you'd review these! Kind of a bummer to see that got some glaring flaws.

[@navidmahmood876]

Did you ever review the previous svs ultra Tower? I’m currently using those and they have a sound signature that has a similar kind of quality, a little shouty at times but also missing some detail in the mids. No complaints about bass esp with EQ.

[@MyFatherLoves]

So very interesting.... So, if your room is properly treated to include "cloud" treatment to catch that nasty vertical reflection, these are kinda awesome. Especially for the price point. Properly tuned for the room, these are almost a steal for the combination of power handling, super low distortion, and horizontal directivity. I'm very impressed by the super low distortion. That's an an impressive metric they hit for the price point. There are an abundance of objectively better speakers who's main struggle is keeping that distortion tamped down. I'd be tempted to get 9 of these for a surround setup if I could find a way to elevate and tilt them down. Tall order though. Very stinkin heavy and tall. Plus, drilling a "tilt-over" stop or whatever it's called into the back of the surround speakers would break my heart. Such a beautiful finish. I'm tempted to try and figure it out though.... haha

[@xTremeSequences]

I cranked these up to the reference level, which is around 99db, using a hyper ncx500 3-channel amplifier. It was very clean but too loud for my listening comfort. I dialed my room in with a lot of Gik Acoustics treatment. No regrets.

[@Gunmastercomua]

Thank you Erin!

[@808labradors]

I didn't think this review was negative at all. If you watch thinking that a perfect speaker exists then yeah it sounds bad but every speaker has trade-offs. I think the positive thing that was mentioned is that the issues are relatively easy to fix as in toning down the bass bump and the lower treble spike with EQ. I do agree with some of the others in that I think the smaller tower (Titan or even the Tower) might be the better buy in this line.

[@hocktooey]

I don't understand the Impulse Response graph comparison between the Polk R500 and the SVS Pinnacle. Does the SVS have a .1 dip that eases into time alignment? Does the Polk have a .2 dip that "shouts" into non-alignment? The graph seems to show both speakers not performing especially well in terms of time alignment. Is this what I am looking at? And I know you hear the Polks as shouty in the upper mids. But it seems like these SVSs are a bit bright and hard to tune to your room. Is this right?

[@ttolst]

The review i kinda expected. All their talk about them just made me think that they picked a concept and went all out on it, and in the process forgot to wonder if it really was the right choice. Just seeing the huge wmtmw setup made me think that both the tweeter would sit too low and the vertical sweet spot would be super narrow, and it was at just 5 degrees. Designing a speaker that really need to be 3 feet out without EQ or it will be super boomy also seems a bit extreme. Finally the integration with the weird curve at the mids that really need eq just seems like the design process was maybe a bit too fast?

[@tbullard3]

How do these compare to the JBL HDI-3800s ?

[@RennieAsh]

Home theatre bass profile lol. At least according to bass curves I used to see in stereo system manuals XD

[@justbrowsing5279]

You talk about reducing by 3db at a Q factor of 1. Could you do a video sometime about what you use for equalization? I have a mini dsp but have found that using it not only causes signal loss (or lower volume at same settings) but also just makes it sound a bit worse. Even with no filters or eq in place. So I only use mini dsp for subs and use a Schiit EQ for the higher frequencies. I would love to have more control over the mains and crossover point by using something like the mini dsp if it didn't degrade the sound. At first I was using the wrong power supply and it was really bad but even with the correct one it's noticeable. It is a very old mini dsp. I wonder if newer models are better in this regard. Thanks in advance.

[@Artcore103]

The newer models measure quite a bit better. As for level output, you can adjust that independently. But yes, toss it, and just get a new MiniDSP Flex, not the 2x4hd. Way higher processing quality and analog output section quality, lower distortion, lower noise floor, everything... it's absolutely a hi-fi solution when used properly.

[@justbrowsing5279]

Thanks a lot man! That's great to hear!

[@justbrowsing5279]

As far as where it would go in the chain, I'm a bit confused as to how to separate the sub signal and still have it level adjust with the mains when I turn my integrated amp up and down. I have a DAC with digital in and left right analog out, and a stereo integrated amp (outlaw audio rr2160MKI) with analog and digital inputs and analog outputs. I'd assume it's preferable to use a mini dsp with digital in and out but that would mean using it before the DAC and then I couldn't separate the sub signal. If I ran the flex with the analog options I could run it from external processor loop from my integrated and then use one of the outputs from the flex to feed the sub and two to feed back to the integrated for the mains. Or do I abandon the level controls on my integrated and just level control from the flex and separate the sub and mains directly from the analog outputs from the flex? Maybe I'm thinking about this all wrong. If you can make it simple for me that would be great. Just looking to use mini dsp for EQ on both sub and mains and to cross the two over how I want. Any help would be much appreciated. Edit. After more reading it looks like using the rca flex with an external dac is kind of pointless as it re digitized and uses it's own dac. So the pure digital version makes sense but then how do I get the signal to the sub? If I go source--Digital Flex---Dac---and then send the analog outputs to the integrated I'm not able to separate the sub with the flex. It seems like the choice is, sacrifice being able to separate the sub and use the digital output flex, or use the analog output flex and either lose the standalone dac or use it and the internal flex dac. I don't love either choice. Again. Maybe I'm missing something but the dac issue seems to be a common one in forums.

These things sound damn good. Don’t let measurements fool you…the human ear likes a little flavor and spice (v-curve). What this helps me understand is voicing in terms of measurements. So super grateful to have this knowledge helping me understand why I like something

[@ErinsAudioCorner]

Well, I listened to them and what I heard aligns with the measurements. Secondly, the human ear doesn't prefer v-curve. It's been well documented that the human ear prefers flat on-axis with neutral off-axis. Check this video out if you wanna learn more: kzbin.info/www/bejne/sKPThneritmrhq8si=3M6g41uWQA9ffXaV

[@QuintEssential-sz2wn]

ERIN: great review, but in your discussion about the speakers time alignment, I was left a bit unclear in how you were addressing the issue. You mentioned that the measurements indicate the speakers are fairly well time aligned, and you did also mention the issue of phase alignment. But I didn’t get a clear picture of what time and phase alignment does or looks like, and its relevance. So for instance, a number of manufacturers claim to have time aligned with their drivers. But they are not phase aligned. Only a handful of manufactures have ever produced truly time and phase, coherent designs, e.g. Thiel, Dunlavy, and the usual requirement for passives was a first order crossover to achieve this. I think it would’ve been informative to mention what a truly time and phase coherent Step response would look like, which is a perfect right triangle step response, unlike the SVS speaker where it looks like lower frequencies were still trailing the initial impulse and it’s not phase aligned. I’d also be interested in your thoughts on the relevance of true time and phase coherence (which of course active speakers using DSP are achieving more regularly these days)

[@ErinsAudioCorner]

I left some of this on the editing floor to cut down on time. But I hear you. That may be a better video by itself.

[@Openeyesopenheart42]

From 100hz to 20k the phase is in a +-15 degree window, that’s really impressive !! Correct me if I’m wrong (I often am) but there is no such thing as a speaker that is time and space coherent at every frequency, especially lower frequencies, the brands you mention and others such as VAF or Duntech all have incredibly “coherent “ designs based around similar principles which you may or may not have heard of. Cheers from Australia

[@bobstinker2074]

great review as always

[@joshcatstream]

Flagship, according to SVS seems to mean ignoring a lot of design principles like controlling dispersion and diffraction.

[@wagnerlopez9451]

Doesn’t seem like 5k speaker, better save for the FR10s from PS Audio

[@justbrowsing5279]

I'm confused. In the past, if I'm not mistaken, you have described "on axis" as having the speakers pointed directly at the listener. Here though, you say you recommend using these "on axis" and show a picture of them pointed straight away from the wall, or at least that's what it looks like in the picture. So does on axis mean pointed at the listener or 90 degrees from the wall, which would be toe'd out from the listener? Thanks in advance and thanks for the review.

[@ErinsAudioCorner]

Look at the graphic again. Pointed directly at the listener is in black and that is on-axis (0 degrees). 👍

[@justbrowsing5279]

@@ErinsAudioCorner Thanks for the reply. I was referring to the photo of the speakers in this video. At 6:07 in this video you say you recommend listening to these speakers on axis. Then at 6:38 you say this is how I recommend listening to these speakers, and show a picture of the speakers at what looks like 90 degrees from the wall. I totally missed the graphic earlier in the video. I'm guessing the photo is just hard to tell where they are pointing.

[@IliyaOsnovikov]

Erin, what's an aproximate ratio between contributions of horizontal and vertical radiations as the parts of overall reflected sound.

[@leatijoseph828]

I have a Klipsch Thx-6000 LCR from 15 years ago and I still use them and they sound great. I compared the Svs Ultra Evolution series to them. The Thx series easily crushed them in movies and there is no difference between the Evolution series and the old Svs. It's not worth upgrading. But I like the Klipsch Thx series a lot. it sounds neutral and detailed, for example, if I were to compare it, it sounds like Star Wars and Kong Skull Island, the mid bass is very clean, but the SVS sounds dirty, I will not change the 15-year-old system for a long time, because there are very few competing brands

[@charlesf2804]

It seems as if simple tone controls (bass and treble) won't be adequate for taming anomalies. Am I correct, in your view? I just subscribed based on this review.

[@bearclaw5115]

I guess my money would be one the 888's possibly or Arendal 1723/1723S.

[@snowinokinawa]

Hi Erin, I just subscribed & liked. Thanks for your review. If you’re not too busy, could you advise me on some more direct radiating HT speakers opposite to the more wide dispersion of this SVS please? My first side reflection points are large windows & blinds on both sides so acoustic treatment is VERY difficult. Some help would go a long way… thank you! Nick

[@ErinsAudioCorner]

Most speakers with waveguides or horn speakers will tend to have more narrow radiation. Klipsch comes to mind with them usually being around 30-40 degrees but there are even KEF speakers which are a bit more narrow (+/-50 degrees).

[@TriAmpMyFi]

. Acoustic treatment is never difficult. It's a choice. Some accept the loss of a view as worthwhile. On the other hand, not all treatment must be glued, screwed and bolted. Think common living/listening room items & how they might be used as treatment. In my listening area, because I want storage, I put a row of kitchen/office cabinets at counter height down both side walls. They're beautiful walnut cabinets. Here's the trick though, those cabinet doors only reflect sound waves & the w.a.f. doesn't want acoustic treatment as decor. So, I put 5" inch thick foam on the inside of the doors and the back wall of the cabinets. I just open all the doors 45 degrees when listening & everything disappears when finished. Think 'Inside' the box. Acid Jazz, Funk & Brass 🔈🔉🔊

[@gusgusnft8231]

Pay $5K and you “still got to fix this speaker.” Passing on the SVS.

Great review! How would you compare these to the Arendal 1723 towers?

[@ErinsAudioCorner]

I can’t say for sure since I don’t have personal experience with those Arendal towers yet.

Do you foresee doing a Klippel test on the RSL CG25 in the near future?

[@ErinsAudioCorner]

Possibly!

[@ma3nni689]

Thx 4 the review. Would u recommend the Arendal 1723 tower in a home theater only setup or maybe 5 of the Monitors over the SVS Set.

[@MechAdv]

I know a lot of times you don’t have control over this, but I’d really love to see a shoot out between the KEF R7 meta and the MoFi 888. Ascend ELX towers could round out the show for towers at the $5k price point. I think this price class is probably pretty much endgame for me. It’s the same quality as what I have currently, but not 25 years old. The quartz composite matrix baffles on my Jamos are pretty damn cool though. They are dead on the knock test. Lol Also, you did a community post a while ago, saying that you used to have the Zaph audio ZRT speakers with the revelator drivers. How would those compare to some of the tower speakers that you’ve heard now in that 5K price category? Worth the time and effort to do a build or just spend the money?

[@ErinsAudioCorner]

I haven’t reviewed the R7 Meta or the Ascend … yet. So I can’t really draw any comparisons there. The revelator series is one of my personal favorites.

[@MechAdv]

@@ErinsAudioCorner For sure, just an idea for a future content piece like how you did the recent “best of” videos for bookshelves. Another idea would be to test the Harrison Labs inline RCA filters to see how they affect FR in the passband. I’ve seen people argue back and forth on that topic and it’s kind of steered me away from analog bass management. They are cheap on Amazon too so they might drive some affiliate link traffic if you find they perform well. Not everyone has a home theater processor or AVR for their 2.1 setup that can apply DSP highpass filters for the subwoofer handoff.

[@Krazychris212]

Would an Emotiva XPA-5 Gen 3 be powerful enough to power these speakers to your liking or would you recommend more power?

[@gtric1466]

I guess it would all depend on how you like your music to sound. maybe in a very large room with far enough side walls they can sound good with a high current amp. But for me I'm a big fan of mid bass and cannot listen to bright at the 2-4 K range in my aging ears. Disappointed because they definitely bring the cool factor.

[@nielsm.2147]

That frequency band is a little bit too messy for my taste. Really hoped for those to be a music/hometheater option. Back to Arendal I guess.

@@nielsm.2147 Why not KEF? The R7 and R11 have incredibly low distortion at high SPL and great compression performance. I’m sure Arendal works well too, but I feel like KEF would image better in 2.1 for music.

what is the point of supposedly time aligning the front speakers, if there are 2 bouncing off the back wall? if they are 3 feet off the wall then that is 6 feet of time misalignment, no? and it looks like they are "time aligned" completely straight up where as, the actual distance from each speaker to our ears would be longer distances the further off center they are. what say you?

[@aaronmatuszny8856]

The biggest downer for me is that tweeter.

[@amazoidal]

For that money, you can buy a pair of Moabs with higher SPL.

[@amazoidal]

Eric is a genius but he can be demanding and difficult. But for concert-level SPL, you need lots of drivers moving lots of air. Almost all "towers" are just bookshelf speakers with more woofers. This expensive SVS model has an extra midrange. Whoopti-Do. How about multiple mids and another tweeter? That's the MOAB.
