I'll take the robaot 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?

Kal Rubinson's picture

What is a robaot?

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.

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

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.

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


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

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.

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

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

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

Lee Robert's picture

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

Kal Rubinson's picture

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.

rschryer's picture

From whom?

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!
