Front Screen wall HELP

Real quick: I have been reading this forum daily since I was in college (past 6 years or so) and I am finally ready to dig in on my first big project. Its time for ME to start posting stuff for once...




So I just bought this house last year and it has a partially finished basement. However not to my likings. So my dad and I are going to tear the whole thing down and start fresh. We are beginning the demo now.


Since my design isn't exactly a dedicated theater (for certain reasons), I would like to dress up the front wall a little. However I want to know if and how much I will be compromising the sound. I have the majority of the plans already thought out and designed in SketchUp.



The majority of the bottom "shelf/cabinet" is comprised of 2 F-20 subs that we will be building. The wall is 16 feet wide and each sub is 5 feet. So I plan to build some sort of filler to make it look like one complete unit. As you can see I would like to add some kind of panel molding to the subs to try and hide the fact that they are...well, subs.


The speakers I will be using are SEOS 12 tempest. Those still need to be constructed as well, however I am going the easy route and getting the flat packs.


NOW on to the issue at hand. Notice I would like to add these side walls. Not sure if we are going to construct them out of drywall or just build some sort of tall cabinet to place on each side. Is that going to compromise the sound in a significant way. I know that I will be limiting the space for sound treatment behind the speakers...if I even have any room at all. Will the side wall create some weird reflects? Does anyone see anything here that makes this look like a terrible idea.


If this is a big NO NO, then I guess I will go the boring route. I really would like to dress it up a bit, but the whole reason I am doing this basement is so that I can finally have a theater really sounds top notch.


Thanks in advance!!,

I think you'll be fine building the "cabinets" on the side. There's always a chance that it causes some sort of issue with the sound, but if you have it professionally calibrated or if your AV Rec has good calibration in it then you'll be fine. The area behind the couch will cause more of an issue than the side "cabinets" would.


Are you placing the front speakers ON the cabinets that house the Subwoofers? That would be probably not be the best placement for them since the subs will have some vibration when in use.

THANKS for the response!


I figured someone would mention that about the area behind the couch being an issue more so. But I do want the screen wall to be seen form all/most angles of the basement for sports games, entertaining, etc. (not just for movies). Hope that doesn't cause too much of an issue though. I do plan to get a receiver with Audyssey MultiEQ XT32 so hope that helps.


As far as the speakers going on top of the subs.....I thought about that causing some vibration issues, however I plan to put some sort of rubber or felt beneath it. I want to say that I have seen some users in the F-20 thread do the same with that placement. I'll do some more research on that.
It's not a "Dedicated" Theater room so you'll have to deal with a not so perfect area. It'll still sound great. Still not sure about the Sub placement, but that's up to you.
If you are using the SEOS 12 Tempest as your center channel, make sure you make the cabinet short enough so it can stand vertically. With that waveguide tweeter, you don't want to lay it sideways as you will have a large vertical dispersion and almost no horizontal, meaning you will have a very narrow sweet spot.


As for the sidewalls, I would make them not as deep as your center cabinet. Or at lease have the front of the speakers sitck out past the walls. If the speakers are set back at all, you will get some weird sound reflections off the sidewalls.

Great point. I did not even think of that. Its my first time dealing with a waveguide design so that one slipped right past me. Id like to keep all three front speakers the same. However I would have to do something like this with the center in order to keep all three...




Not sure about this. Might look a little funny. I'm guessing I would also have to angle it upwards a bit. Would I be better of building a real center channel. I just looked at the "Fusion-8 Alchemy MTM" and it seems to have good reviews.


Here is what that would look like. All of this is to scale as well incase anyone was wondering.






Also as far as the walls/cabinets depth is concerned...I plan on making the speakers stick out past the walls, I need to fix my design in SketchUp.

The only thing I don't like about the Fusion 8 MTM is the waveguide still looks like it is sideways for a center channel. The Fusion 1099 Center has the waveguide rotated to be a true center. No matter what you use for a center, you will have to angle it up.
I will look in that. Thanks for the advice.
