Re: Question about headroom with dj mixers
QSC told me a while back that at full bandwidth, bridged into 4 ohms the amplifier will be delivering about 1,700 watts average power, and so that's good enough. I know a lot of people are using Crown I-Tech amps but i've not chance in hell of ever being able to afford one, I was lucky to be able to afford my SRX728S subs, I paid them off slowly, one by one over a year. I got each MPA750 amps for £250, wheras a used Crown I-Tech8000 costs about £2,000, even the I-Tech6000 costs about £1,500 used. With regards to the high pass filter, the music I play is oldskool hardcore rave which has a lot of 30-40hz content and the low frequency makes up a lot of headroom of the tracks being played so i'm gonna leave the high pass filter at 31hz I think, although i'll do what you say and at least have a listen, see if I can tell any difference in setting it at either 31hz upto 35hz.
