I've been playing around with various enclosures for this driver. It's a bit of an odd driver, in that while it can go very low in a vented box, it doesn't necessarily go all that loud. In this case, the box is 30 Liters, tuned to 25 Hz. This gets us an F3 of 23 Hz; very nice! Problem is, those low notes will max out excursion at 100 dB (@ 70 watts)
So what can we do with this? Certainly, it's not going to work for large-scale home theater. However, this could definitely work for music lovers who want to make sure they hear the lowest octaves out of their recordings. Such people usually listen at more reasonable volumes (say, 85 dB), and the driver and amp should be very comfortable there. By many accounts, The RSS210 is a very high-quality sub, and it should provide a much higher fidelity than, say the Dayton SD215-88 (don't get me wrong, that's a great driver, too). It would also work for small home theaters. It may be a little big for computer users, but who am I to say?
I came up with three different design ideas.
The Pony - A speaker-stand-turned-sub. Driver can be front or side-mounted. It uses a slot vent for no particular reason; I just wanted to see if I could draw it. One could just as well use the vent from the Burro--or maybe the vent from the Turtle.
The Burro - A rectangular prism. Sits lower to the ground. Driver is side-mounted (magnet carefully placed to keep center of balance). Meant to be tucked next to furniture or an entertainment center. It uses 3" PVC, a lot of it.
The Turtle - A simple cube. For some reason, this is a popular shape for subs. I never understood why. It's pretty much impossible to use 3" PVC in this box, and a slot port would be too much extra work. So as a compromise, I think the 2" Precision Port kit should work. The port is downfiring because I was concerned about chuffing and because the flare is so large it won't fit on the back.
The cabinet walls won't need to be lined unless you cross really high (there is a pipe resonance at 250 Hz).
These are just concepts. I haven't built any of them yet--but I will. I am confident that they will work, though, and since this sub driver has come up lately, I thought I'd share some useful ideas. Click below for diagrams.
