Any comment as to how the K2 936 sound in comparison to Aria 936? Inquiring minds want to know! I will say, with those neon yellow drivers, the WAF may suffer in comparison to the flax drivers.

As to the tweeter height, I also seem to have the situation of my ear level being a foot or more below the tweeters on many modern tower speakers, which is one reason I really like the way Focal positions the tweeters on the Kanta series.

At least Focal made the sound signature downward sloping to account for the directivity mismatch at the tweeter. However, would have liked it not to be there in the first place and thus allow a neutral listening window. Maybe it’s for higher sensitivity, but I’m not totally sure why so many companies have woofer sides drivers act as midranges (6.5” crossed at 3100Hz), 4” is usually the largest you want for good directivity.

Focal doesn't use the same drivers for midrange and woofer's in their speakers. The midrange are designed to work as a midrange and the woofer are made to work as a woofer, the drivers do their job as intended - but yes many other companies, use the same drivers for midrange and the woofers.

is luscious and deep! I love the yellow aramid drivers in contrast as well.

Focal (formerly JM Labs) did not begin in Paris but rather in Saint-Etienne just outside of Lyon where they are still located.
Aside from that minor quibble, thanks for the enjoyable review.

rschryer's picture remove that quibble.

As per Wikipedia: "Focal-JMlab, a research office dedicated to acoustics was founded in 1979 in Paris..."

So we're good? :-)

Hi Robert:

Thanks. I wasn't aware of that. I had visited the factory several times (as a dealer then. now retired) and talked to M. Mahul and he had never mentioned any Paris history so I was unaware of that. You learn something every day!

Thanks again for the review of what sounds like a lovely product.

...Wikipedia is not always a reliable source. Both Robert Deutsch's review of the Aria 936 and the Focal website indicate that the company was founded in Saint Etienne, France. I would venture that Leefy made the comment in a good faith effort to correct a minor error, which should have been caught in editing, in what is otherwise a very enjoyable and informative review.

Thanks David

I did not want to pursue it as it might have been seen as pedantic (and it is a minor point) but I appreciate your kind words as I do think the Paris reference is an error on the part of Wikipedia. I'll leave it at that and stick with enjoying Robert's enjoyable review. Thanks again for your comment.

if they included bi-amp terminals.
three way towers are prime candidates for bi-amplification.

Maybe this Focal model has been designed to be sensitive enough to operate without need of bi-wiring/bi-amping.

That said, I am a die-hard bi-wiring advocate ! IMO, bi-wiring (or bi-amping for this matter) can improve the sound of its single-wired version big time due to substantial reduction of hi & low requencies intermodulation inside the SAME connecting cable.

I converted my KEF 2-way standspeakers to bi-wiring by re-design/building its lousy factory X-over to do the job many many years back. The bi-wired conversion has made substantial sonic improvement with the rest of the rig remain UNchanged.

In fact, quite a few brand-name loudspeakers come with such biwiring/bi-amp terminals, including bookshelves. It only shows those bi-wired loudspeaker makers got good musical ears.

Bi-amp will be another story as it will involve complex outboard active/passive hi/low frequency crossovers & acoustical level balancing. It can be a can of worms for every Joe Blow consumers.

That is certainly one possible interpretation. ;-)

We have an unsolvable conundrum. As in, it's getting ridiculous, but this is what we've gotta indulge to survive. (I worked in the trade press for many years, and have personally experienced the, er, existential havoc wrought by the internet, beginning in the mid 90s and accelerating to death star mode after the bursting of the dot bomb bubble ca. 2001.)

You could buffer the output of your existing amplifiers (flea powered tube amps?) with a pair of Musical Fidelity 750k Superchargers (circa 2008), and use those to power the loads full spectrum, if you can find some available for your purchase. The point of the exercise is that the Superchargers can power difficult loads while presenting an easy load to your tube amplifiers (you may need to add a suitable resistor across your amplifier outputs in parallel with the 50_Ohm load presented by the Supercharger), and the nonlinearities of your tube amplifiers will dominate the resulting sound character of the amplifier combination. Or you could buy a different pair of suitable amplifiers.

I suggest that you consider using VituixCAD to provide a graphic showing an EPDR curve with impedance and phase curves with respect to frequency. In the image below, the dark gray color curve is impedance, the light gray color curve is phase, and the violet color curve is EPDR (Equivalent Peak Dissipation Resistance).

While VituixCAD is free for private use, and you could try it out that way, the author Kimmo Saunisto charges €200 for first seat commercial license, and €50 each for additional commercial license seats.

You can import measurements taken using Arta Labs' Limp. A commercial license for Arta's software package is €149. You can try it for free.

I understand that you have Audio Precision measurement gear, but this is quick, easy, effective and accurate, and with laptop and compact outboard gear is more easily luggable when and where that might be an issue.

I have no affiliation with any of this. This is just a recommendation, not SPAM.
