Transmission line speakers!

I own T+A Criterion 2100 TL speakers.  I believe all the T+A Criterion speakers are transmission line.    Very deep, natural and linear sounding bass for midsized floorstanding speakers.  Never boomy, even in my room with hardwood floors. 

If they are in your price range, I'd take a listen.  I think they have one of the best transmission line designs.

Those are beautiful speakers... impressive

Thank you.  I think they're fantastic speakers.   They do require quite a bit of power, so they wouldn't work well with small tube / class A amps, but they sound great and are easy to work within a room.  Another advantage of transmission line vs ported is that room placement is less critical, and mine are working in a functional living room (a less than perfect space) vs a listening room.
