DynamicPower

Anyone? I bought a 9PIN DIN cable to connect between the DD-5.1 and the PM 5.1 sub and it did not work!

That's what I'm thinking too Dynamic. Someone check my math on the Surface Area. I am not known for having the best math calculating skills Because I can't type. I meant to add a 3dB gain. I believe I remember correctly that when you add a second sub, you yield a 3dB gain. If you stack them, you yield a 6dB gain. Can't stack these (probably wouldn't want to due to the LCD panel on top). I got the same area as you so I think we got right I actually got 6dB gain when I had them placed in my left and right corner too.

Interesting comparison! I have dual RSW-15 myself. Dual RT-10D should outperform a single RSW-15 with a good margin. The surface area of the RT-10D's 6x10" woofers is significant bigger than RSW-15's 2x15" woofers. The amplifier in the RT-10D is also rated at 100w RMS more than RSW-15. Edit: I have stacked my RSW-15's on the top of each other and have a 6dB gain after perfect phase adjusting (when I turn one of them off my Radioshack mic measures 6dB lower output). Why do you only get 2dB gain with dual RT-10D vs single RT-10D?

Anyone looking to sell one of these? Thanks!
