[QUOTE="Atjan, post: 184055, member: 2323"] WOW! Sounds a great project you're raking on. Ito required power for your amp, I reckon the efficiency of your speakers will have a massive impact. Check out Chuck Hawks' website for a nice little table that illustrates the point. Basically a speaker that is 3dB more efficient will require an amp of half the power to reach the same spl as the less efficient speaker. Also consider your listening position relative to wheee the speakers will be. For every meter you move away, your spl drops by 6dB. Which requires 10x more power input. Example. At 4.6m with a 89dB speaker you need 842W to achive 90dB spl (your 601's are 88dB). With a 92dB speaker you would require 1681W for 90dB! Edit: Keeping in mind that at that power fed in the 601's would long have given up the magic smoke ghost. :) [/QUOTE]
