Default Help with speaker planning / selection for family room

Ok, so I must preface this by stating that the "heard, but not seen" adage definitely applies here. Wife just decided to add a tv to the main entertainment area in our house. It's a large (20x35ft) room with high, vaulted ceilings. Seating position is about 13ft from the tv and the tv is on one of the long walls of the room. Use will primarily be tv and movies (but we already have a theater in the basement). Speakers will be powered by a marantz nr1603.

The main constraints are created by the tv stand (pics to follow). From what i can think of, It essentially requires a low-profile center channel to be housed either above or below the tv. I was tentatively planning this design for the center channel and something similar mounted in the wall on either side of the stand for a 3.0 system.

I'm definitely open to suggestions, help, & critique!

Thanks,

-john

I quite like the look of these - Speaker Design Works

You may recognize the drivers here: Click

IIRC someone used one as a centre channel speaker.

Troels has a good very selection of diy speaker designs to suite all budgets.

Think about on-wall panels.

You can get some ideas from Artcoustic:

I had thought about on-wall vs. in-wall and didn't think it would be a viable option due to looks, but I'm beginning to come around. Any idea what they use as the "oversized baffles"?

The little Magnepans might look good in there if you need something that's not a box, but they're a little anemic without a sub.

Maybe something like this: Dayton Audio ES80W 8" 2-Way In-Wall Speaker Pair 300-372

Edit: The design using the markaudio drivers is kinda cool, but again, as stated by the designer of the markaudio drivers, "They are not woofers." They're not really designed to play much below 50-60 cycles with any amount of authority and asking them to play loud is probably not a good idea.

Hi, worth a look just to see how the design changes for the various options, rgds, sreten.

update: on-walls are out. a sub is out.

so i'm basically left with in-wall speakers on either side of that tv stand thing and one center channel under the tv. The CC seems rather straightforward given that i have plenty of depth and don't need it to go below ~80 or 100 hz.

I'm stumped and would definitely appreciate a nudge in the right direction on the in-wall speakers. i can't find anything anyone has built/designed that narrow (3.5in - 4in) that is still going to have decent bass response. another constraint: any port needs to be close to the driver so i can cover with one grill.

is this possible?

As far as I know, In wall speakers are all of the infinite baffle type, so you won't have to worry about ports. If you're looking for a diy in-wall setup, I'd send you to the page mentioned by sreten, here: Zaph|Audio - ZA5 Speaker Designs with ZA14W08 woofer and Vifa DQ25SC16-04 tweeter

There are some variations of these if you scroll down that are designed for in-wall.

Edit: You'll probably have a tough time with ~4" of width, your life gets a lot better around the 7-8" widths for main speakers.
