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.

Good suggestion Soliver,

The 90dB/4 ohm speakers that I mentioned working extremely well with the Almarro A318 "A" & "B" were Jean Marie Reynaud Twins mkII monitors. Their floorstadning models are equally easy to drive and provide greater low frequency response.

Easily my favorite line of moderately efficient speakers.
The Speaker List (in no particular order):
Silverline Sonata III
Gallo Acoustics Ref 3.1 w/Ref 3 S.A.
Reynaud EV3
Triangle Celius
Acoustic Zen Adagio
Merlin VSM-xxx

Others? Comments?

The Integrated Amp List:
PrimaLuna Prologue 2 (KT88 or EL34, 40wpc)
Ars-Sonum Filarmonia SE (EL34, 22wpc Class A, 40wpc Class B)
Eastern Electric M520 (EL34, 24/18wpc Class A)
Wright Sound WIA1515 (EL34, 15wpc)

Speakers: Gershman AvantGardes - they go down to 24 Hz (87db/8 ohm, 40w min recomm power)- great WAF factor.

Amp: Onix H6550 Integrated Amplifier (6550 or KT88, 50wpc) (30-day in home trial)
How about an alternative with a built-in 250W amp. All you need is a good preamp and you've got a great stereo/home theater set-up.
