Looking for Speaker Recommendations in Home Theater Posted December 9, 2002 bhawk, w/ that 307 you have flexibility (or stressful options ) galore. i have basically the same w/ the ref 30 & b&k 7270 power amp we can give you some general guidance but when it comes down to it, the settings that sound overall best to you w/ your room, your tastes, your material, your specific equipment & source material is what matters. iow, some experimentation is most likely needed. to utilize all your stuff w/ the space you have i'd use one heresy for the center positioned so that the horns are nearer the screen & the woofer farther away. iow, if above the tv then turn it upside down. then use that other heresy for the rear surround "6th" channel. should be directly behind your head in the sweet spot, but still should be better than nothing. that's a great sub. & wish i could fit my cornwalls up front. on the amp for the ultra, not sure if it has a crossover control, but if it does disable it or turn it all the way up to 120hz or higher. you have all the controls you need for that in the b&k. in the 307, after of course doing the speaker levels & distances settings, i'd start by setting all the speaks to small, crossover at 60hz, & both high & low slopes to 12db/octave. also sub to "yes thx" & phase to normal. but again these are just starting points. the 307 also has a notch filter to take out some of a worst peak caused by room node. there's bound to be at least one. you'll definitely need a sound meter. that notch filter has a freq sweeper all the way down to 20hz. only a quick start here that covers some basics. the 307 manual is pretty thorough i think, though it may leave out some scenarios. sort of like written by a tech person. let us know if any questions.
