[QUOTE="oldschool4me, post: 4174657, member: 581630"] i was not saying we arent, just saying it makes as much sence to me. rear fill to me is just as improtant. not as important to other people but you will have that. some like it some dont. havent seen many sq comp systems with no rear fill. but i think we are somewhere around here, quoted from above.... It is important that conclusions we draw in theory are realizable in practice, otherwise the theory is inaccurate. And if you look around, there are a number of installs that either use multiple midbass or midbass in the rear (or both) with great success. Off the top of my head, there are some guys you might have heard of known as SpeakerWorks who have had great success using midbass in the rear. It isn't a tactic that is used often because it is still widely misunderstood, but offers great potential. Imagine, for a moment, that you have a small 6.5" driver up front. You play it down to the crossover point but obviously lack the output you're looking for. Good news! You may keep it in the current bandwidth, add large midbass drivers in the rear, keep the difference in front/rear arrival times below 30 ms, lowpass below the frequencies at which IID becomes prominent, EQ out any unevenness, and gain output with no effects on localization. Much like the use of a subwoofer in the rear, it is important to minimize resonance of surrounding panels. It's complicated but the result is worthwhile. [/QUOTE]
