vman71 Posted February 16, 2006 Share Posted February 16, 2006 I don't know what the optimal CII speaker positioning is and I was hoping I could get some advice. The attached picture is how I have them set up now. For perspective, the room is 15ft (w), 20ft (l) and 8ft ceiling. The CII's in the picture are spaced at 9ft apart and very slightly toed in, 2ft from the back wall and 1.5ft from the side wall. I don't think this is the right distance for a PR speaker, so I'm looking for advice. Thanks, Mike Quote Link to comment Share on other sites More sharing options...

DrWho Posted February 16, 2006 Share Posted February 16, 2006 Just as an experiment, I would try moving your left CII to the left and bring the subwoofer on the inside. I've helped some guys with similar rooms/setups to yours and it always ended up sounding better that way. As far as toe-ing in is concerned, you want to point the speakers directly at the main listening position. Moving the speakers wider will allow you to toe them in more, which will also reduce the amount of early side reflections off your side walls. You might also consider moving the speakers a bit forward too...as far as you think is aesthetically pleasing. Speaker positioning is one of those free mods you can do to your system that can also have a pretty dramtic effect. So feel free to experiment and note the difference between each position before you try the next one. Heck, for experimentation purposes try pulling your speakers a good 5 feet into the middle of the room. Btw, are those doorways to the room behind the speakers, or are those pillars? With all that space you could custom build yourself one insane subwoofer...and in the meantime the volume taken up by the sub would help alleviate the helholtz radiator action those corners probably have.

wuzzzer Posted February 16, 2006 Share Posted February 16, 2006 No comment other than that's the highest I've ever seen a center channel mounted! [] Quote Link to comment Share on other sites More sharing options...
vman71 Posted February 17, 2006 Author Share Posted February 17, 2006 DrWho - those are doorways to get behind and into the built-in space. I have to shave about 1" off the bottom of the doors so they can close. Right now, they are too low and the speaker cables get in the way. After I get the doors to close I'll try and swap the left CII with the RSW-15 and then move the right CII closer to the wall. Wuzzzer - That is pretty high for a center channel isn't it [] Unfortunately, I wanted to keep the shelf for the HDTV at around 30" and I wanted to have 3 shelves for audio gear (with a little room to breath). So that left me with having to place the KLF-C7 above the HDTV space. I plan on tilting it at an angle so that it points directly at the couch seating area. Thanks for the advice on the CII placement! Quote Link to comment Share on other sites More sharing options...

vman71 Posted February 17, 2006 Author Share Posted February 17, 2006 Duke - what's your recommendation in terms of distance from the side wall and back wall given the room that I am working with. There is no WAF in the Man Cave [6] Quote Link to comment Share on other sites More sharing options...
DrWho Posted February 17, 2006 Share Posted February 17, 2006 lol, if you get "boom in the corner" then you've got some acoustical issues to sort out - there is nothing inherant about the corner that makes the CII's boomy at all (cuz that's where I have mine) [] In your man cave....I should point out that those front corners are going to act like helmholtz resonators (a fancy way of saying they will have an inherant resonance...kinda like porting the room). This can be either good or bad and I suppose if I wasn't too lazy we could calculate some of the offending frequencies. It is further compounded by the fact that your doors are forced open right now [] Anyways, the point is that in order to get best bass response you really need to look at some acoustical treatment. My speaker positioning suggestion had way more to do with the mid/high frequencies...and getting the sub out a bit from the corner will reduce it's boominess. I would suggest an 80Hz crossover with the CII's if you're not doing that already... Quote Link to comment Share on other sites More sharing options...
