[QUOTE="Etac, post: 5129442, member: 570589"] yeah i understand what you're saying but the thing is i know its the amp thats clipping, but i think its clipping because of the speaker...and the resistance the speaker presents at given freqencies... ok, am i wrong when saying... let me think how to word this... say you set the gains to run 10 volts .. (ignore resistance for now) now given an equal signal reguardless of freqency.. the amp will always try to produce that 10 volts, correct? ok, now assuming that is true, now lets add resistance into this equation.. lets take 4... 10 volts @ 4 ohms = 25 watts now lets take 12 ohms... 10 volts @ 12 ohms = 8 watts.. now like is aid before, the impediance changes throughout the speaker.. depending on the signal (freqency) thats running through the coil at 100 hz say its 4 ohms... at 60 hz say its 12 ohms... now you give it a 10 volt signal playing the ranges 60-100 at 60hz it would be producintg 8 watts.. at 100hz it would be producing 25.. lets assume 10 volts is the limit for clean power so does it a) still produce a clean signal... just plays it lower since its only 8 watts or.......... b)since its trying to make an equal signal.. at both these points, it cannot.. the signal its outputting is clipped at 60hz because it cant reach its peak and hits a wall from resistance..so the top of the sine wave becomes flat and clipped...
