Best subwoofer for Linn AV system


I've been reluctant to buy a sub, living in a condo.......but the upgrade bug is going strong and I'm considering buying one.

My system consists of Linn AV5103 pre/pro, 5xAV5105 amps (soon to be activ for the front) which consists of AV 5140's and an AV 5120 center, Snell K.5 surrounds. I'm inclined to go with the Linn sub (AV 5150), but it is $5000.... I'm wondering what experience others with similar systems have had with other subs and how it's worked out.

Any help would be greatly appreciated!!

See my thread under "Linn AV4140 feedback?"and also "HT subwoofers"
I personally do not think that there is a problem with the AV5150 subs ability to play loudly(if it is set correctly... crossover/positioning relative to the listening room)although I am about to add a second one (BIG room)
But my strongest recommendation is to listen to everyones opinion,listen to all subs available to you and then make YOUR own decision...let us know how you get on
Marc774, I have two as well in a very large room (w19'x L34' x h12'). I added the second not to add volume but to tighten up the lower frequencies, which worked wonderfully. I agree - set up and room positioning is critical to performance.
It is amazing how GOOD musical bass can be miss-understood for LOUD(30-35htz hump) bass.I did not mean to imply that loudness was my reason for consideration of a second sub.Kevin M my room is not as large as yours at 32'lx8'hx15'w(but I unfortunatly do not have the keltics)so when I get to borrow a second I am sure I will be £3100 lighter
Marc774, well said -- the goal should be for accurate (musical) bass. You should find a noticeable improvement with a second 5150. E-mail me if you would like suggestions on placement, I can provide you with what worked for me.
