    I bought a Samson S1500(750Wx2) to power some Stryke AV-15's. While building the tubes for them I had spare materials so I built a small sealed sub with an original SVS CS driver I had lying around. It's 2 cubic ft with 20oz of polyfill.

    Until the Stryke drivers arrive, I'm using the SVS based sub. I'm pretty sure that giving it 750 watts would be too much for that single driver. I haven't bottomed it because I've been careful, but I'm worried of the thermal damage. So is turning the the knob on the front of the Samson(it goes from -80dB to 0dB)to it's half way point going to make the wattage cut in half? Is this a safe way to go about powering the subwoofer?

    I'm not sure if the gauge on the pot is accurate enough to call it exactly 1/2 but as long as you keep the gain down you should be safe. I've done similar things and I still have my drivers intact.

    OK so how about this

    1.) I play a LFE tone
    2.) Measure the output w/my SPL meter
    3.) Turn the Samson down so the meter reads 3dB lower

    Is this now the same as cutting the wattage in half?

    BTW, Dave that chloroform joke is damn funny.
