Looking for a good small subwoofer...


A friend bought two smallish horn speakers, wants to beef up the bass with a pair of small subs, (preferably piano black) with built in amps and active crossovers to send line-level high-pass signal back to his EL84 class-A amp to the main  speakers.
These aren't going to get super loud, just fill in some low bass.

Any ideas?

Thanks,
Steve.

Am presently quite satisfied with a pair of REL Strata III’s, 100 watts each, 10 inch driver, rated to 18Hz (though when I tested them I got a response at 16Hz), made in the 1990’s.

They’re accurate with no muddy, sloppy boom.

It took a little while to find two good deals, but I eventually rounded up two for less than half the price of one new.

I also have the mk10 speedwoofer . Paired with elac 2.0 unifed ub52 speakers  love the sound. 

Had a dynamo 800x from Martin Logan.  Did the job, sounded good and wasn’t huge. 

Love my REL t9x.  IMO can't go wrong with REL.  But, recently listened to a Kef kc62 and was very impressed.  Goes down low with no muddiness and is tiny!  Thinking of one for my living room.  Not cheap though.
