I'll take the robot over any reviewer as long as Paul Seydor's wife Danielle says it desn't sound like hi-fi. Now I'm down to the age old question, will it play my reference albums and recordings?

The Kippel is an important tool to measure speakers. Kind of a shame Amir is the only reviewer using it.

While I have personally spent >$50k on test equipment over the years, the $100k the Klippel NearField Scannner costs is out of reach for me financially. :-(

There is also the fact that the Klippel needs to be used in a space with a 10' ceiling height, which is not feasible in my NYC home.

Nevertheless, I don't feel my loudspeaker measurements are lacking.

for a discussion of measuring techniques for loudspeakers. I'm going to use measurements from a Klippel when I can. I don’t use yours because I want to measure speakers myself. And of course, play my reference albums and recordings in an environment I control.

I recently acquired a new SUV and have heard six tracks from my reference albums in the last month. It will be an adventure to adjust the audio system to play them reasonably well.

also uses Klippel, but for what it's worth, JA's measurements do get the job done, except for maybe loudspeaker THD measurements.

vs Klippel is A little like Garry Kasparov vs Deep Blue. Deep experience vs pure processing power. Each obviously has their strengths and weaknesses.

SamTroft's picture

Dont know who Amir is but Erin's Audio Corner has been using Klippel for his reviews.

RoryB's picture

Klippel's measurement systems are capable of many standard measurements including acoustic response (frequency, phase, impulse) but it is unique in offering additional measurements such as laser scanning, LSI (large signal nonlinearity testing), and distortion measurements including electromechanical DC offset. Those who work in the industry, myself included, will tell you that the specific measurements the Klippel system offers beyond the standard measurements Stereophile obtains by other means are meant to aid in the development of products, usually focusing on a specific transducer in the system (a woofer, midrange, or tweeter in isolation) but do not have direct correlation to what you as the listener will experience in the context of the fully integrated loudspeaker system. You do not hear the suspension symmetry of a loudspeaker, but you will hear its impact upon dynamic compression or harmonic distortion. You do not hear the breakup shape of a transducer diaphragm, but you hear its impact on the frequency and impulse response. You do not hear the offset of a transducer's BL curve, but you hear harmonic distortion and sensitivity loss from an out-of-magnetic-center voice coil. The more advanced Klippel tests can tell you a lot about a specific component of a speaker system, but when you look at the complete integrated system together (drivers, cabinet, crossover, porting) a lot of that information recedes into the background as minimally relevant. At most, you are checking the designer's work. The standard measurements performed by Stereophile are still the ones most directly linked to what you will hear.

rt66indierock's picture

Funny that the Klippel system found errors in Ocean Way's speakers that I heard as something is a little off at shows before Covid-19. And I don't know of many speakers that get past my nine reference albums and three reference recordings.

dc_bruce's picture

While it certainly seems possible that system of this size could be set up for bass extension to 20 Hz (-3dB), the designers apparently have made a choice to forego that in favor of a bit more efficiency. Given that most home listening environments have a 3 to 6 dB boost in the 40-50 Hz range, it's likely that, in-room, this speaker is "flat" to below 40 Hz. The result, according to Kal's report is plenty of bass power (undistorted, uncompressed loudness) achieving a sense of realism that most people want. As Mr. Austin's footnote advises, those wanting 20 Hz extension can always add a subwoofer or two (of equal dynamic capabilities to the main speakers) in order to hear the "hall sound" and other ULF. Given that most subs feature self-adjusting room correction, this probably would result in better sound than a totally passive, uncorrected single "full-range" system of equal LF extension.

Jack L's picture

.........uncorrected single "full-range" system of equal LF extension." quoted dc bruce.

Hi

IMO, SURELY not "probably".

My experience tells me active sub(s) when blended properly with any "full-range' loudspeaker system will surely improve its ULF than without.

I finally get back the music I missed soooo much before without my active subs installed!

Listening is believing

BluesDog's picture

No small feat competing well against your Revels. Also would you say it plays better ported or sealed?

Kal Rubinson's picture

Dunno. Only used them as ported, at the recommendation of the distributor/installer. Also, despite their supposed good accommodation for subs in the sealed configuration, a domestic speaker of this size would most likely be employed in stereo in most systems and would be expected to perform well without subs.

BluesDog's picture

Thanks, Kal. How far from the front wall would you say is prudent?

Kal Rubinson's picture

??? Prudent in what way?

BluesDog's picture

As far as I’m concerned John and Kal are among the best there is at what they do. They are in Elysium, which we can almost grasp but which enlightens us and helps us to be better. John will always be the standard by which all testers and their equipment are measured. I’ll take John’s meticulous approach, scientific consistency and sheer will over anybody else and the latest “Flux Capacitor” out there. John gets my lifetime vote as the Michelangelo of testing components and speakers. Kal consistently produces gem reviews with insight and music choices that unearth a speaker’s capabilities. We, as readers, get a frequent real treat from John, Kal and the rest of the Stereophile Audiophile Squad!

Thank you. I appreciate your comments. About consistency: I have always felt that consistency of approach to testing and the presentation of the results is important. The loudspeaker tests in Stereophile feature a common format that allows a speaker's measured results from 30 years ago to be easily compared with those of current-day models.

Dan Nagar's picture

Thank you for an amazing review about amazing speaker.

this one as all the bass needed .

the issue with sub woofer integration should be considered in every system and its not related (always) to fronts speakers extension or specific in room response( again - in terms of room gain)

sub or multiple subs - configured correctly will give a much smoother response .

thank you again

Hi

Hopefully the speakere driver units are NOT made in China as well !!!

..are all made in China. They appear to be excellent performers.

Hi

Thanks but no thanks !!

US$20,000 USA brandname loudspeakers BUT 100% made-in-China ????

Glad Stereophile honestly pointed out its country of origin as no indication showing its manufacture location at the back panel of the loudspeaker.

IMO, what a very smart way of making audio consumers' money by building them in an OEM overshore cheap at the expense of the qualtiy consistency of the product.

Good luck !

If these same speakers were 100% made in USA (assuming that this would even be possible today), they probably would cost twice as much or more.

Jack L's picture

Hi

So ??

When many digital fans can afford $10,000 +++ for a DAC, would they worry to spend $40,000 for a pair of front loudspeakers, a very major component of the home audio rig, made 100% in the country of origin?

Yes, quite a few loudspeakers manufacturers get their products assembled in China using wooden boxes built there (huge cost saving) but still using the critical components, e.g. speaker driver units & other electronic parts supplied by the original manufacturers. That's will restore the consumers confidence.

Likewise, I never own a car not built in its country of origin.

Jack L

PS: I fixed quite a few tube power amps built in China provided by my audio friends. I got good experience how good are China-built electronics.

What will instill (rather than restore) consumer confidence is the track record. Obsessive adhesion to "country of origin" is only a little piece of the puzzle.

Jack L's picture

Hi

My question as a consumer:-

Is the "track record" based on the loudspeakers made in USA or made by OEMs offshore ??????

Otherwise I would consider such "track record' INVALID without disclosing where the products are actually built.

There is no countdry of origin showing on the loudspeaker box. So why ???

Neither. It is based on the loudspeakers of a particular manufacturer.

Quote:

Take a closer look. On terminal panel on the back of the speaker, just above the terminals, it says "Designed and Engineered in the USA - Made in China"

Jack L's picture

Hi

"Presumptuous" !

Sorry. The picture showing the loudspeaker panel above only shows, in pretty fine letters: -
"& engineered in USA & made".
So you still assume we readers could presume it is made in China !!
Ironically, all other signs on the back panel, e.g. THX, Dominus, even
minor signs like RoHS & CE are so much larger in size to be seen so obvious.

"track record" - "Neither" ..

Please defne your meaning for "traack record" to avoid further confusion to naive consumers like yours truly.

Jack L

Kal Rubinson's picture

Now you are just being churlish. The country of origin was clearly indicated in the review. It is, also, printed on the back of the speaker and visible to anyone at a showroom, even if not completely so in our photography.

What is meant by track record? The most general meaning (from Oxford via Google):

Quote:

the past achievements or performance of a person, organization, or product. "he has an excellent track record as an author"

Consider this my final reply to you.

Jack L's picture

Hi

"Churlish" !!

When I asked you how you determine the performance of the loudspeakers when they were made-in-China, you redirect the issue to something else: "track record".

So what is that to do with its geneeal meaning by Oxford.

Likewise when Bill Clinton's presidential career was ruined by his affair with his intern, so would YOU still take Bill's brillient performance in the past as 'excellent track record' ??

This is my last response to your non-answer to the above.

When I measure a product I always take a photo of the back panel and the box, showing the country of manufacture. Though my photos weren't included in the review, the Perlisten's terminal panel does indeed say "Made in China." This information is included in the review's Specifications sidebar.

No disrespect but I will wait for a more credible review before I seek these out for a demo.

If you doubt our credibility, you can easily find several other reviews out there but, of course, I cannot vouch for their credibility.

Ortofan's picture

... a better way for 'Lee Robert' to have phrased that comment, rather than "wait for a more credible review."

Following is a link to another review (that includes a set of measurements) and their results essentially confirm the findings of KR, along with those of JA1.

Kal Rubinson's picture

My remark was not to impugn other reviewers nor did I intend to provide links to other reviews but as directive in response to the implication that our review was less credible than other, yet undefined, reviews. They do exist and Mr. Robert should use Google to seek them out.

BluesDog's picture

I can’t believe how many people engage in what the Brits would term “rather shirty” remarks just for attention. People the caliber of Kal and John have WAY better things to do then defend themselves from what radio announcers were forced to call “bullsch.” I read another article about the Perlisten S7t with testing. While a good and decent article, Stereophile is always the gold standard. It’s like comparing Double AA or Triple AAA baseball players to the Gods of Baseball, Sheesh! Long after the universe has shrunk to it’s last dying star, people will be saying about Stereophile reviewers, especially Kal and John, To add lib Aztec 2Step: There will never be a faster gun or another one like you are!

So to snarky readers here is what bikers would have to offer: Sit down, shut up, and hold on!

gpdavis2's picture

Reads to be an excellent speaker. However, as long as China continues to steal our (and other free-world country's) technology and manipulate their currency to undercut free/fair trade I'll not own anything made there when I can possibly avoid it. Why support our economic enemy who may in our lifetime become our military enemy?

Kal Rubinson's picture

I respect your position. These days, it is difficult to avoid products of complex technology that do not contain any component part from China.

Jack L's picture

Hi

I can't agree more. We are dealing with a major Communist
country, no kidding !!!!

Now quite a few free-world countries. led by USA, have already declared boycotting the Beijing Winter Olympic Games next year by not sending any
official delegates to its offical opening ceremony !! First in Olympic history ever !

Some countries even consider to stop sending over their athletes to the Game. Let' see !

Yes. Absolutely true. I'm sure my new Pass INT-25 will have any number of lower-value parts made in China. As you state, impossible to avoid. But, when one has the choice.......... stick with the free-world when possible.

Has anyone besides me noticed the close similarity to the XA (expanding array) David Smith developed at Snell for the XA series back around the year 1999?

The bracketing of the mid-woofers, two mid-ranges and a dome tweeter in a waveguide looks very familiar to me. Even the stated design goals of the XA array echo what Perlisten is looking to achieve.

See this review in this very magazine...

https://www.stereophile.com/floorloudspeakers/334/index.html

I am going to compare the JA test results, as applicable, to look for similar measurement results. It should make for interesting reading.

And for the record, I am still the happy, original owner of a pair of XA90's. Thank you David!

And as far as 'Made In China" is concerned: I too will avoid purchasing high-dollar goods sourced there. My preference for solid, long term reliability and serviceability win out over price for high-dollar purchases.

And lastly, thanks to all the folks at Stereophile for a great publication.

prerich45's picture

Yep it reminded me of the the old Snell XA's. What it reminded me even more of was my own Infinity Composition Prelude P-FR's. The configuration is very similar but the craftsmanship on the Perlistens is just out of this world.
For those who talk of China, I understand buying USA, however most of the magnets in our speakers come from China, due to them having the metal that they're made from. Circuit boards, TV's, and more have Chinese materials in them. It's impossible to avoid in a modern world.
I'd also like to shout out a "Bravo Zulu" to Kal on his review. I trust his measurements, and they're verified by the spins that are included on the Perlisten site. I believe between Kal, and the other independent reviews out there, we have enough data to say these speakers measure well. If Amir can get his hands on a set, I believe he will come back with the same answer. As far as Perlisten goes....specs and data wise, I've seen enough - I'm a believer. Now only if I could get out of Audiophile prison and PERhaps LISTEN to a pair.

prerich45's picture

I've went back and looked at the measurements and I'm surprised at how close they are. Both have a recommendation that says "Dont listen to these speakers while standing", I found that quite amusing indeed!!!!

steve59's picture

If one was to remove all the parts from everything we own that have any china sourcing we would have to walk to work barefoot and wouldn’t be responding to this review because wtf do you think your typing on?

These speakers look to have original thinking and solid engineering and I’m glad you guys found them then took the time to share them with us.

Buckchester's picture

Great review, Kal.

In the upper bass difference you describe, would you say this area lies below the room transition frequency? If so, I wonder if this difference might have more to do with how each speaker interacted with your room, from their respective positions, and less to do with the speakers themselves? After all, many of us would be applying EQ below the room transition frequency anyways, so if that difference disappears after doing that, then I personally wouldn't put much weight on it anyways.

Also, I've read the these speakers are probably able to play much louder with less distortion than some other worthy competitors, such as your speakers or the 328be. But I wonder, in most rooms, would that extra ability actually provide a real added benefit, or would you need an extremely large room for that benefit to be aparent?

Thanks.
