In ceiling subwoofer build
Its been some time since I have been on this forum. Building a new house with distributed audio. I'm doing 32 zones of audio. 26 of these zones will consist of stereo speakers for the inside and outside of the home. The remaining 6 zones I'm going to use for subwoofers. I will then have programmed into the automation system to have the subwoofer zones come along with certain regular zones. I'm doing this for those rooms where I want a little extra oomphf!
I started looking around for good in ceiling options for subwoofers. Most everything I find is pretty weak, so the thoughts of building something on my own creeps into my head again. I told myself with this new home I wasnt going to do anything weird or build my own stuff, but the more I think about this, I dont see how it could go wrong. I want superior fit and finish so that it doesnt look like I built it. Here is what I was thinking. There are a few different options, but I was thinking of buying a Monoprice Alpha 10" subwoofer that comes with a magnetic grille. They are $99. I would be removing the driver from that and basically just using the pre-fabbed subplate with the magnetic grille. This will get me my fit and finish. Then I would order a nice 10" high excursion driver. Maybe like the Dayton Reference 10" or other suggestions? I would then build a 2.8 to 3.0 cubic box that would screw directly into the rafters accounting for drywall depth, etc. Once house is complete, I attach magnetic grille and there you go....
This is just a basic process I laid out, but you guys get the idea. Some issues I can see:
1. Can a subwoofer hang upside down without having any sagging issues? I'm sure this really isnt an issue because it would be an issue with all ceiling speakers then
2. The Alpha sub plate might not have the right holes for the high excursion 10". or the back of the Alpha may not accept the high excursion 10". I suppose anything could be modified though.
3. During playback, the high excursion sub may extend much more then the Alpha sub, therefore hit the grille causing it to rattle or fall off?
4. Should the sub be ported? If so, ports would have to somehow be cut into the face of the sub plate
5. Noise traveling to other rooms? This really would not be too much of an issue either as box will be well insulated
6. Will it sound good? I dont see how it would not sound better then anything I could buy up to and probably over the $1000 range. This whole setup would cost me about $300 to $350 to build
