Older model.
15" IA DP
Dual 2
Will be getting 1400 or so daily rms

What would you guys say is a good size for the box?
What to tune it to?
Website recommends 3-4.5 but I think that's for the new ones.
I also know everyone on here likes to build giant boxes :veryhapp:

Anyways, there's a box in the classifieds that is 5.8 tuned to 34hz, you think that would be good or too big for the DP?

4.5 @ 35hz?

4 @ 40 will do this thing nice. I had a Sonic FX Q 15 (basically same woofer), put it in 4 cubes @ 40hz. Still slams the lows like crazy.

Get a design for a folded horn.
