I'm highly impressed with the level of detail and help provided by the crew here. I was referred to this site by Mark Seaton while attempting to get some help with a possible build. I can see why he sent me here. I should have probably come here just due to the fact that ThomasW is part of the site. Thanks to him my next house will definitely have an IB.
Here's a little bit of background. I've been bitten by the bug and have recently begun upgrading my generic big box theater equipment with quality items. Currently I'm employing some low end Klipsch surrounds/surround backs and center. I've got some old monkey coffin mains. I have an eD A7s-450 on order which will be tamed by a DSP1124 and I'm running the whole setup with a Denon 2809ci. I spent a lot of time listening to different subs before I picked the A7s and had begun listening to mains. I had planned on running the bass on my mains a little hotter than usual in order to meet up with my sub (which will be a little hot too). I'm a serious fan of bass but if this isnt a realistic goal I can change it.
During the auditioning process I listened to some Klipsch reference series and some KEF mains and really didn’t get the level of satisfaction with them that I would expect for the price paid. I subsequently found my way here and have become intrigued with the full size Statements.
The room I have all of this setup in is 14.5' x 11' x 8' and it has six 2'x4'x2" home made treatments built using Knaufboard. I've got them at primary and secondary reflection points and centered on the back wall. I had planned to put them behind the front speakers as well but if I'm building statements I don’t know how that would interact with the transmission lines from the mids. I have all the equipment to run REW except one splitter which should be getting here within the week. At that point I'll measure my RT60 and treat from there. Depending on what positioning you guys suggest I may hang some on the ceiling and integrate some lights and a star scene to get the appropriate RT60.
My TV and components all rest on custom shelving to get them to the appropriate height. I had planned on building the statements sealed, without a base so they somewhat resemble large shelf speakers. This way I can move the shelving back and forth from the wall to accommodate whatever spacing I need to ensure the appropriate sound.
In my auditioning of mains I've established I generally enjoy the sound of sealed speakers more than ported. I realize porting generally gives better bass response but if I can get strong, flat response to below 80 hz I'll be happy. In Mark's curved trapezoid build he added some volume to the top and bottom. I believe I read somewhere that the width couldn’t be changed but the height and depth could. Is this something I should consider to increase their bass capacity?
While perusing the supplemental info on how to arrange crossovers that the admins stick to most build threads, I had come up with the idea that I could layout my crossover covering a significant length of the back of the speaker, making it accessible by either a hinged or sliding door. Its an effort to get the inductors away from each other and anything else that can affect them. I see that most people line their boxes with sound damping materials. I'm curious if some sort of speckle covering could break up the rear wave. Something similar to sponged ceilings. Would an absorber be needed in addition? Is it a horrible idea? Also, how do you route the wires that connect the crossover network to the drivers? Are they free hanging within the enclosure or are they affixed to the side with staples or the like?
So far I've gone through 3 or 4 of the statements build threads and I'm making my way through the original threat but it’s a monster. I know I've got a lot of questions but I'm trying to cover all my bases and wanted to be thorough. All in all, no matter how they turn out I know I'll enjoy them unless I seriously monkey them up somehow. For the money involved, the fun of the build and the quality of sound they're capable of its win-win. My father is a cabinet maker for enjoyment so I'll no doubt have help whether I want it or not.
Based on what I'm looking for, should I build them ported?
How should I change my treatments to accommodate the open mids?
How much more volume must be added to the box to reach the best bass response without having to change the crossover?
Is it a good idea to have the crossover laid out with distance between the components?
Speckling inside the box. Yay or nay?
Info on routing the wires anywhere?
Thanks for any help,
Adam

ops: The room I have picked out for the theater in the new house just about double the length. Its about 13' x 20' x 8'. It sits over the garage so I shouldn't disturb anyone while pumping everything turned all the way to 11. I'm spec'ing everything to fit the new house, plus its always better to have more than not enough. My plan at this point is to build the statements as mains, the center and 2 sets of monitors for surround/surround back. I have plenty of time to build between now and when we move so I can do it right the first time. Or at least try to.
