Efficient Speakers with SS Powered Subwoofers for SET amps?


Been loving my Martin Logan Expression 13a but I need my tubes back. Been enjoying low powered SET amps again and would love to use them in my primary setup. Currently running a Woo Audio WA5 that is doubling as my headphone rig. Will probably end up with something else in the near future. 

Trouble is I'm having a tough time getting off the powerful authoritative bass coming from the Martin Logans and their 300 watt class D 10 inch woofers. I've seen the Zu Audio definition's with their powered woofers but I'd like to spend less. Ideally under 10k. Looking to run the tubes for all the mids and highs with solid state running the lows. 

I realize I could simply run a separate dedicated sub but an all in one package is more appealing and space is a concern.

Can you guys make any recommendations?

Thanks!

@larryi  Yeah I've been hearing good things on the Rethm speakers. I particularly like how they designed the Bhaava. It's really nice to see a fresh take on what a speaker should look like. The idea of using a full range driver for its entire range and then a sub to prop up bass impact seems like a great idea. I hear Voxativ is coming out with something similar in the near future. 
@chrisallen I to have owned a number of Omega Speakers and agree with you about the drivers in a box cabinet. That said the tractrix designed Charney horns take the RS7 driver to another level. Very close to the Lowther drivers Charney offers but with a slightly warmer tone. This horn design offers plenty of punch with involving micro and macro dynamics. If you get a chance audition them, you'll be glad you did.
I agree with "rodge827" in regards to Digital Amplifier Company.  I own a pair of the Golden Maraschinos and use them with my Tekton Double Impact speakers.  Fantastic match. 

Chrisallen,

Voxativ already has several models that feature an active (powered) woofer coupled to wide-range drivers.  I haven't heard their speaker systems, but, I have heard a number of different systems utilizing their drivers.  The sound of these systems varied widely; clearly implementation plays a big role.

The Charney speaker I mentioned above used a Voxativ full-range driver.  Charney offers a choice of drivers.  For my taste, the Charney with the Voxativ driver does not need a subwoofer.  The sound was full and had plenty of bass.  If anything, what I would want is a little bit more extension on top.  That is a somewhat strange thing to say because sound a bit harsh and have a prominent peak in the treble range that makes one want "less" on top.  This speaker was quite different from the typical single driver experience. 

Chrisallen,
Voxativ offers the Zeth B and the 9.87 system which both include a powdered subwoofer. I’m quite certain that these are more expensive than the Rethm alternatives.

If I weren’t so happy with my current system I would acquire the LM 508ia (or a used Viva Solista) and Tekton Double Impact SE and not look back.
