Amp For PG RSDs

give those rSD's at least 100 watts rms.....they like lots of power....profile amps are good for the price.....i've bought 2 off of millionbuy.com

i know i have said this in about every post regarding what amp to run one these but give them as much power as you can afford. the more the better. more power will make any speaker sound better and clearer, and have better dynamics.

i have mine running active on 200 rms per mid and 100 rms per tweeter. i have had them on this amp for the past couple of months and they show no signs of stress at the volume levels i listen to(which sometimes is pretty loud). as long as you are not trying to make a single set keep up with 140db's+ of sub-bass then they will get plenty loud for most.

i can guarantee all the people who have blown a mid or tweet either tried playing the driver to low (to low of high-pass filter) or didn't have enough clean power on tap and clipped the shit out of them.

i think most people just aren't aware of how dynamic music is (or should be if recorded well).

Music is not constant in its peak amplitude. The ratio of average power to peak power is in the order of 10-20dB. (10dB = 10 times power and 20dB = 100 times power). I would imagine that modern rock and roll/rap music the value is closer to 10dB. This means that with typical music the average power when using a 200w/ch amplifier is in the order of 20 watts per channel with the peaks rising to 200 watts. Anything higher than the 20 watt average will most certainly push the amplifier into clipping.

so say you get a 100 watt x2 amp.... if you are using music that has a 10db range you'll only be getting an average of 10 watts if you want to keep the amp from clipping at all.

so... it's not just the RSD's that need lots of power, but any speaker will benefit from having more amplifier power.

just purchased the aura force for 45 bucks

You should have gotten more power but maybe it'll be good enough if your expectations aren't too high.
