Does this speaker exist?

Drubin - you just described the Thiel sound! Will not fit your under 40" height though.

For Rrog above, I had the SCIII many years ago at home, and used to sell Dunlavy back in the day - the 'III is missing the bass foundation that the 'IV has in spades...actually, except for being too tall, the 'III meets the OP's criteria right down the line.

But I doubt you'd find them satisfying, having grown accustomed to the more full-range sound of the 'IV.

Hi Drubin,

I'm with Vapor Audio, and I believe we have exactly what you're looking for.

There is no finer transducer for treble than the RAAL tweeter. We feature the RAAL in most of our speakers. Nothing offers a more transparent window into the music than the RAAL ribbons. Their moving mass is actually less than the mass of the air they engage to create the sound.

If you're looking for a small footprint, have a look at our Breeze, Stiff Breeze, or Sundog models.

For a review of the Stiff Breeze, please have a look at HomeTheaterReview.com and Terry London's impressions. You'll get the state of the art tonality, transparency, and versatility. We'll throw in the disappearing act and sound stage, no extra charge. ;)

The Dunlavys I have are the SC-III.A, which is like the Cantata. Decent bass foundation.
