OK, in an ideal world I think I would like to place the sub near a corner behind one of the main speakers but this won't be practical in my setup. I have two other choices that won't look too bad but I'm wondering which has a better chance of performing best sonically in the H.T. The sub will not be used for my normal music listening, just the H.T.First, I'll be sitting much closer to the main speakers (~ 8-feet) vs. the rear surround speakers (~ 12-feet behind me). I'm thinking about placing the sub far behind me near one of the rear surround speakers -or- immediately behind the sofa. Would it be better to have the sub way back behind me or immediately behind me on the back side of the sofa? Thanks!
Follow Ups:
I was able to find a spot for the sub up front tucked in a corner behind the main speakers. I am also using a center channel and rear speakers of the same brand and nearly the same specs as my two front main speakers. All of my speakers have an 8" main driver. The center is rated 50Hz - 20KHz +/- 3dB and seems to blend nicely with the mains. I set each channel speaker size to "large" and I'm running the LFE output with a 60Hz or 40Hz cross-over. I'm still experiementing but so far I'm happy with the results.
Try all set to small with low xover, thats what I prefer...

At least in most music mixes, if not all movies. This would make placement of the sub in the rear unneccessary. And distracting.
I built a 12" sub into a 3cu ft box finished it to look like furniture and placed it between my mains. This way any directionality is associated with the "front". As it is, when the music or HT music matches the way I have the sub set, (crossover, volume) then the bass sounds like it is coming with the rest of the sound from the mains. In my case the corners are not available anyway. It is a natural part of the sound. This excludes the LFE and that is so low that it is somewhat directional because the vibrations in the floor are stronger closer to it, of course. I have found that recordings vary widely. Find an average setting and live with it. There is a sub amp available that has a remote volume control.
Set the crossover low, 40-50 ans try it behind you. Any higher and the music directionality may become noticable. Even in a heavy, isolated cabinet the low end will excite a joiced wooden floor. Do you have carpeting?
Any way I'm pretty happy with the way it's turned out. Plus taking the low end away from the mains has improved their sound dramatically, they're more responsive in the middle.
Low bass is not entirely non-directional (contrary to popular belief) so you may (or may not) be able to locate the sub if it is in a rear corner 12 feet from you. It will give bigger bass there, however. Behind your sofa would probably be better if the sub doesn't need corner re-enforcement.As always the best advice is "Just try it". I would add, "and live with each for a bit." In HT, your first love may not be something you wanna live with.
I am using a HSU round sub. The manufacturer designed it for near field performance, for the most even bass response. But I found that anything over 40hz was localized.When I upgraded to a 5.1 bass management system, I moved the sub to one of the front corners of the room, to blend in with the front and center speakers better, and was able to roll those speakers over at 80hz. with decent integration.
The largest amount of movie sound track info goes to the center speaker. If your center (like mine) has limited bass response, I recommend locating the sub up front. Also, the LFE channel may go higher than you think, adding to the localizing problem ( some movies use a constant "rumble" during a high emotional scene, which is very irritating if you hear it coming from behind.
I have a $100 JBL full range 3 way speaker, actually prt of a pair of $200 speakers, and they FAR exceed my $320 JBL center that i sold on ebay. Find a cheap pairi of full range speakers that you like the sound, and replace the center with one, an give the other to my brother, like I did.
Since it looks like multichannel music is here to stay, my next speaker upgrade will be a minimum of a matched threesome across the front, preferably all full range.
I'm with you on that one... I'm kinda sick of seeing the special "center channel" speakers that are wider and have two mid-woofers... what's the point?For a balanced sound across the front, you should really have three of the same model. Honestly, with how more receivers are just packing equal wattage amps across the board instead of weaker ones for the rears, it really makes more sense to have the same speakers in the back, too.
I'm going to build a center version of my front speakrs with matching drivers. Actually all five speakers will have scan speak 9500 tweeters and the three across the front will all have the same 7" drivers also from scan speak. The rears will also have 5" Vifa drivers. Six 7" drivers across the front with three tweeters ought to do it for our room. The rears should also be adequate. If they sound small if/when multi-channel music blossoms I can always build bigger speakers.
I agree with the previous posts. I have found the information on the Video Essentials disc, gives a reasonable starting point. You will have to move it after that, but at least the disc gives you an idea.
