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!

Golden ear Triton One or Triton Reference. Triton one are 92 db efficient and Triton Reference are 93 1/2 db efficient. Triton Reference has a 1800 watt class D subwoofer amp, and Triton One has a 1600 watt class D amp. Both have 3 powered woofers with plenty of very high quality bass and both have a level control to dial in the amount of bass wanted.

Bache audio also had some interesting stuff I saw at the last NY audio show. And they are supposedly high efficient speakers too...

I think I am actually going to pick up a Line Magnetic 518ia to play around with so I will have a few extra watts. The Golden ears seem really interesting but I can't get over their plain jane looks. Will certainly read up on all of the other recommendations though. Thanks guys!

Hi chrisallen,
Good idea regarding the LM 518ia. I would give serious consideration to the LM 508ia amplifier. For not much more money it is a 48 Watt SET so operation is pure class A (as are all SETs). What’s very unique is it uses the 300b as the driver tube which is a DHT (Directly heated triode) for the 805 output tube. So you have a DHT driving a DHT. Owners of this amplifier who have posted on this site say the sound quality is simply superb. The 508ia is said to be a step above the already very good sounding 518ia which is 845 output tube driven by 6L6/6V6/el34 or KT 88 tubes. The 508ia is sonically comparable to the higher cost 219ia which also has 300b driver tube for an 845 output tube.

Charles 1 dad's suggestion of the Rethm speakers is interesting.  I heard one of their speakers not too long ago and it was quite nice sounding, particularly for the money.  I believe it had a built in powered woofer and utilized a full-range driver to handle everything from the upper bass on up.  It is efficient enough to work with a SET amp for the full-range part of the system.

At a much higher price, the truly full-range Charney speakers are quite interesting.  I heard them operating as a one driver, full-range system (no subwoofer), but, I think a subwoofer that came in at a fairly low frequency would help that system.  It was also quite efficient too.
