Re: question about an underdrive pulley

if you have a system of any size, don't even consider the underdrive pulley. I have one and love it, plus I got tired of my 12's and sold them.

Where did you get this information?! On the contrary, I have the UDP and two amps (RF 400a4 and 500a2) for my sound system and I noticed ZERO power/bass loss before and after the installation of the UDP. I know my setup isn't huge but to say not to get the UDP if you have a system of any size is simply talking out of your behind.

There is indeed a power drop, how large, I do not know. I have the feeling that if your stereo is under 500 watts you should be ok.
