one or two Sub-woofers?


I am considering a purchase of either one Audio Physic Minos sub-woofer, or two Audio Physic Luna subs. The total value of either package will be almost the same. My system consists of Martin Logan CLS speakers with VAC amplification. My listening room is of medium size. I would greatly your opinions. Thank you in advance...

1. What is your front end and wall juice? If either are lightweight you may not be getting the sound you want.

2.I would RESPECTFULLY suggest you eschew subwoofers in favor either a Wolcott amp and/or Sound Lab M-1 or A-3 speakers. All of these items are final purchases.

3. Finally, and most relevant, your room may not support the weight you wish.

If you wish email I have been down that road.

Enjoy,
I would recommend getting one of the better one. The quality of the bass is more important then the quanity.

But then down the road I would upgrade and add a second one. Of all the upgrades I ever made to my system adding a second sub was one of the best. Better imaging and seperation and was more like a cable upgrade then just adding more bass. I was also suprised in how much it cleared up the sound.
I agree that one great sub is better than two not so great ones. But two great ones (stereo subs) is the way to go if you can afford it. So if you're on a budget, I agree to get one now and save up for the second one. For your speakers consider the REL Stadium III or even better a Stentor III.
