and a:
Bash 300W Digital Subwoofer Amplifier

Here are my questions:
1. Are two Transducers enough for a 2 person couch?
2. Is there a big difference between the TST209's for $79 or the next level up at $130 each?
3. Can I mount these to the frame of the couch or do I need to have something as a buffer to protect against heat?

Thank you very very very much in advance!

I am not sure about the difference btwn the 209 and silver, but I followed BD's lead in the first post and bought my TST239 (sliver) on ebay. The seller had a "make an offer" option, and I got it for $100 shipped. For our couch (in the gallery for reference), the silver is plenty. I am using a BASH amp from a friend's BIC PL200, and we have it a little above 1/3 power. If we put it under 1/2 power, the "ride" becomes crazy... a little too much at times.

But I think there is an important factor indicated in the manual that gets overlooked: bracing. The manual says to use hardwood, not MDF or plywood. It is all about transferring the vibration from the shaker to your body. As I understand it, using soft materials for bracing creates loss of energy from the transducer as the bracing flexes. I would with hard wood backed with steel rods (ones you can get for adjustable wall shelves). I built a double "H" structure under the couch and attached it to the rigid, structural frame of the couch. Used construction adhesive and angle brackets where I can. Finally, don't forget to put rubber feet on the couch.

I guess what I am saying is, based on my experience with the Clark transducers, it isn't about adding more shakers. Clark makes some strong transducers (at least I can vouch for the silver). For a mid to small couch, one is plenty IMO... as long as you install it properly and provide proper bracing as per the manual.

As for heat, I don't think it runs hot... well the driver doesn't run hot... don't know about the amp if over driven.
