Tube Friendly Speakers - Down to 30Hz - $3000?


I'm looking for speaker recommendations that play down to 30Hz. Able to be fully driven without compromise by tube amplification with as little as 15wpc.

$3000 new or used.

16x19 room. Rock, jazz and classical.

Reasonably small footprint (Klipsch K-Horns and LaScalas are too large).

I have eliminated Zu Druid and Tones from contention. All other options are open.

Thanks in advance.

I remember that Tetra review, mainly because it was negative. One of the few negatives ones I have ever read. But then again, maybe in your room they would be awesome? who knows...
Another tube friendly speaker: Devore Gibbon Super 8...90db, 8 ohm, 36Hz-40Khz.

I believe with my desire for bass, there are only a few speakers on the list so far that I can seriously consider, and I have yet to hear any of them.

They are:
Silverline Sonata III (93db/6ohms, 25Hz-25Khz)
Coincident Super Eclipse III (92db/14 ohms, 28Hz-35Khz)
Reimer Wind River GS (94db/4 ohms, 24Hz-30Khz)
Tyler Linbrook Signature System (92db/4 ohms, 25Hz-25Khz)

I'm using the CARY Silver Oak model one speaker with cary 805's

Huge soundstage with awesome bass.They are occasionly available used for 3000$.
Senna, I haven't been able to find any info about the Cary loudpspeakers. Perhaps you can post a link?

Here's a good article from 6Moons that lists ten SET friendly speakers and amplifier combinations. It was written by Srajan, apparently before he discovered the Zu Definitions, otherwise I'm sure they'd have been on this list.
Tvad,

Don't want to sound like (pardon the pun) a broken record, but I believe Kevin at Upscale has Cary Silver Oaks on hand. Honestly, I have no affiliation with the guy, I just think his inventory is heavy on the kind of stuff you're seeking; SET amplification and good partnering speakers.
