cool. i bet they do sound good, such a full sound from big woofers. i am just starting a smaller build based on the LS3/ 5a monitor using the highly regarded aurum cantus 5-1/4 inch woofer and the also highly regarded scan speak illuminator soft dome tweeter. looking for ultimate transparency and livliness with an 89db sensitivity. going for a butterworth 3rd order high and low at 3000 hz to keep the drivers out of trouble without additional filtering. this is a fun part of the hobby. i think we need to have a strong audiophile background to understand just how good ( or not ) these projects compare to the best oem designs.
