Recomendation for speakers BEST for Piano?

Frogman...Agreed: four full octives down from middle A at 440Hz results in 27.5Hz. How many composers have actually used this bottom key?

Here is the question that I would like to see answered.
My subwoofers are flat to 20 Hz, as verified by spectrum analysis using test signals and plainly evident by ear. The source electronics are capable of extreem LF output as evidenced by strong SW activity when playing certain recordings of organ music. A warped LP also keeps them busy.

However, when playing almost all other classical music, some of which subjectively sounds as if there is lots of bass, the subwoofer cones scarcely move. This is verified, not only by listening close to them, but also by lightly touching the cones.

Regarding the beat frequency subharmonics, these would be created in the listening room by proper reproduction of the fundamentals, and do not require reproduction of the subharmonic frequencies themselves. This is the same as in the performance venue, where the instruments do not directly generate the subharmonics.

Eldartford: Ever listen to alot of Jazz with Tenor Sax's,bass?How about a 20" kickdrum? How about big band with a few tuba's? Though I currently dont use subs(but will be soon)and have floor standers that are flat to 20hz, I feel Im still losing a bit of presense. Same holds true for the other end of the spectrum with other instruments.

Truth in the matter is that your subwoofers shouldnt be "flat" to 20hz. The last 2 octaves(20-80hz roughly) should be tuned to be about 3-4db higher up at least, while the top 2 octaves(5khz-20khz) should be roughly attenutated about the same amount for our ears to percieve a flat natural response due to our ears natural sensitivity. I just wanted to touch base on this, I dont know how you setup your own system, but if it was flat across the board its gotta be really bright sounding.......

To shorty interupt: I will settle for Cary slp88, Odyssey Stratos monoblocks and HARBETH STUDIO 40. Will buy them used, of course. Just mention my findings regarding ESL or Planar speakers that i auditioned. ML and Maggies have certain qualities, but as far as natural sound, they aren't as good as dynamic speakers. They sound very FAKE! I do not know about Quad though. Thanks for your suggestions.

Muralman, I now understand your passion for the Scintillas. Whatever part of the "Ground Hog Day" loop you and the Apogee Corporation are trapped in I am so glad that it allows you to revel in obsolescence.
Frogman, you are right on. Physics and mathematics defy the appeal of the Quads but they sound most like a piano to me too.
As to frequency response I can only say GET REAL. Name me a recording with a 20 Hz tone, please.

Although people know Im bull headed about being a big fan of dynamics speakers, Planers,esls etc do come in handy in certain circumstances. For "easy listening" at low volumes I do have a place in my heart for my ML prodigies, though they are nothing compared to the Salon's.

Harbeth Studio 40's: Very nice! =)
