So I'm entertaining the idea of building a DIY sub. I don't have the necessary woodworking tools myself but know someone who does. Let me put up a hypothetical budget of $600 for drivers, amp, and cabinet materials.
The room this will be used in is right at 1000 ft/cu, so pretty darn small. I want to achieve at least reasonably flat response down to 20Hz with the best possible sound quality within the posted budget. Currently, I am using an M&K MX-70. It's a dual 8" push-pull design with a 125W amp. It's extremely tight, but starts to roll off under 30Hz. For its size, the amount of bass it can put out is impressive, but it can sound strained or even bottom out easily with big movie soundtracks and some very bassy music.
My set-up is 80% of the time for music (and the MX-70 hardly lets me down here) but for the remaining 20% of the time watching movies or playing games, I want much more extension and power.
First, I don't know what design will suit my needs best. I'm leaning towards sealed for arguably tighter sound and a smaller footprint, but could go ported if it wasn't too big and didn't sound boomy. I think doing a dual push-pull, M&K style or otherwise, would give the least distortion but could I get similar results with a single 15" than with dual 12"s?
Basically, for all you sub experts, what would you build for a room this small to get the best sound and good extension?
