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.
