What subwoofer to choose for 2 ch and HT combined

Since you have a pretty top-notch 2ch set-up I would not compromise it any more than I had to. A pair of subs with a high degree of adjustability running off of the speaker taps would be the best way. This way you would be completely out of the signal path and could switch the subs off if you desired. This would mean sending full range torturous bass from movie soundtracks to your main speakers. If they dont distort without the subs durring movies I wouldnt worry about damaging the speakers.

I like the Martin Logan Depth personally. Room size and sub placement will dictate what works best for you though. You will want a sub whos lowpass slope compliments the LF rolloff of your Meadowlarks. The Vandersteen 2Wq/2W is worth looking at too.

Good luck!

need more info on the room and setup....

Aerial sw 12

I myself would recommend a UFW 12 sub with R-DES digital equalization from AV123.com. They have a fast, and musical bass response, and the controls on the back of these units allow for a high degree of flexibility. The R-DES is basically a room correction system for your sub, allowing you to really flatten the fr of the sub in your room.

I would also invest in a decent set of sub cables that are able to deliver fast, solid bass.

Thanks very much for the responses. Will definitely check out the UFW and aerial. Have already heard good things about the Vandersteen although I understand they have a "music" model and a "HT" model. Anyone with experience in both, i'd appreciate your opinion on those.

TweekGeek, I agree with your comment about cables. I run DH Labs and JPS everywhere else but have a cheap cable for my current sub (a $500 Jamo sub that's about 8 yrs old). I need to run about 15 feet. Any suggestions without spending huge money?

FLrnlamb asked for more details on my room. Room dimensions are 15.5 x 17 with the longer distance being my viewing and listening direction (ie speakers face down the 17 foot stretch). Carpetted floor, ceiling start at 8ft and climb to about 9.5 however its not a true cathedral in that it raises then flattens out at 9.5ft. Room is on a second floor but the floor is build with a silent sub-floor. I have the flexibility to place a sub(s) in front, right side or rear. Currently have my old sub in front.
