Should I run 4 or 8 ohm mids?

[QUOTE="keep_hope_alive, post: 7831536, member: 576029"] "active" when powering 6.5's and 8's on the same channel? nah. defeats the purpose. just eliminating passive crossovers is only part of it. "active" is using electronic crossovers to properly filter each speaker, especially speakers of different sizes. it's not about "ultimate SQ". it's about spending money and time wisely. people don't complain about "comb filtering" but i can measure it in any of your installs. our performance spec would require you to EQ the system, which is near impossible with comb filtering - since each seat will have different nulls and peaks. what sounds good is subjective. in general, people are used to phase interference and distortion. they are used to reproduction systems that are poorly implemented. the majority of performance spaces are poorly done. the majority of concert halls have acoustics issues. in general, few people have any clue what they are doing. and most PA installs have left and right arrays when the source is mono. DOH! Hell, just plug your installs into EASE and you'll see it there, you don't even need a mic. i battle constantly with people saying "that's how i've always done it". just think if we took that same approach to medicine... where would we be? /acoustics rant [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] regardless; if this was a thread asking about running 10's and 12's off the same amp channels, the responses would be different. but when it comes to playing frequencies where it actually matters...
