[QUOTE="VWBobby, post: 7367662, member: 624844"] You are taking what I am saying out of context or splitting hairs with my statements. I was talking about pushing your equipment to 75% or higher, not your "stereo". If you have a sub that can handle 1000W RMS, you are powering it with a 1200 or 1500RMS amp to have a little headroom, 750W RMS or higher would be 75% (of 1000W RMS). It has nothing to do with the amplifier. We are talking about subwoofers. In my statement about Paper and Wool cones, I mention nothing about a Pulp reinforced cone. A pulp fiber cone is nowhere near as light as a paper or wool cones. Its almost similar to cardboard or MDF in materials.... Nice try, but anyone who can read between the lines isn't falling for it.
