I'm planning to have SR71 Zaph kits all around (left, right, surround channels). The center channel will be placed on an Omnimount rack above the 65" Mits DLP TV (max load = 30lbs). I may want to build it with 5/8" thick wood (with good bracing of course) to keep it light as 30lbs isn't a good max to build by.. might be too heavy.
Here's the questions.. Is the reason that most people build a 2-woofer, 1-tweeter center channel design (WTW) because of symmetry? I would have no problem adding an ER18 woofer to the already "perfect" SR71 kit, but I'd have to figure out how exactly to change the crossover in order to accomodate impedance doubling/halving (and also crossover points would change). Would it not be a good idea to "simply add another woofer" to an already great design? What would be the easiest way to do that? I do know that cabinet volume would be double (2 woofers instead of 1) so that is one con.
This brings me to another thought.. why not just use one woofer like the rest of the mains to keep everything nicely matched/balanced? Well, the tweeter would have to be positioned above the woofer, and that makes the height of the enclosure larger, at least around the tweeter diameter. I understand that I don't have to encompass the tweeter inside the enclosure, and there are designs out there that just use open baffles to "hold" the tweeter.
Why not use an externally mounted supertweeter like in high-end designs? I know these are sometimes extraordinarily expensive, but it would look very low-profile and sleek! Is there an inexpensive external tweet for this purpose?
Lastly, I think about coaxials as a possible solution. I do love my center channel speakers to be large because there's a lot of midbass stuff there these days. It sounds much fuller with a larger woofer too.. I know that with a coaxial, I'd be cool with even an 8" and I'd mount that in a box that wasn't too wide. I was thinking a sonotube idea would be really cool, as long as 15" depth was enough (that's the depth of my DLP).
What would you do? Should I just use get another Zaph kit and use half of it for the center, and maybe the other half for the center back in an in-wall install behind me? Or should I just understand that the center may need to be completely different in order to work with the aesthetic aspect? I'm open to ANY suggestions here. Whatever idea I choose, I'm making the enclosure for the center to have a height that is just barely larger than the woofer diameter to help keep it more slim looking. Of course, this means it needs to be either wider or deeper, but what have you found to look best? Wouldn't a sonotube type center be best or would that increase the effect of "there's something big sitting ontop of the TV!" ?
