subwoofer help 10" or 12"
 

i have a very stupid question bvut i need an answer to it.. if someone want to make a setup of two 10" subs and one 15" sub.lets say 10" have 300rms each and 15" have 600rms so total adds to 1200rms..and the amp is providing 1200rms so no body can say the subs arent performing well.now you know each speaker performs best in a specific frequency range will the setup with 2 10" nd one15" sound better or say will reproduce better and acuurate low frequencies over two 12" rated 600rms each..what exactly i wnt to ask is if neglecting issues like brands,cost ,kind of muzic and listning environment AND humans cannot make a big diffrence in listning low frequencies,box dimensions or why will sm one need such high power etc ctc..which setup will sound more ACCURATE 2-10"+1-15" or 2-12" having same rms values and givin power.thanx..one more thing ppl say i wont mix up diffrent size speakers but none of them had tried doing it or heard this combination..its just an imagination but i need good advice over it from you professionals

A buddy of mine at one time had 4 8" sealed and 2 15" ported. Sure it hit hard, but wasnt very musical. He then switched to 2 10" with the 15s. Same thing. Now hes running 2 good quality 12" running the same power, and it sounds much smoother over the frequency range. IMO i like the 2 12s better.

Do not ever mix and match different size subs in one set up. It will always sound like poo. Always use the same size, make, and model if you are going to run more than one.
