Box for 4 SA 8 v2's

[Dan2427]

I'm wondering if this box will work for 4 SA 8v2's. First question, I've heard the v2 has too much motor force for a sealed box is that true? Second if the first is true, can I buy 2 4 inch aero ports for each side of the box? If I do that they will be firing out the side toward the doors if room allows for it. I plan on running 4 on a AQ2200d, or AQ3500. Also since the box is pre fab how would I go about figuring the tuning for that box with two 3 or 4 inch aeros? Thanks a lot!

Also it will depend if I can go ported or not if I get the 3500. It will be tuned with DD-1 with -5 track either way but if I go ported the enclosure is on the small side so ill over power them a little. If it stays sealed I'll run them with the 2200d since the enclosure will be too big on the sealed side.

There won't be enough room in the chambers to fit two ports of either 3" or 4" per side.

You could fit a single 3" x 14" long to tune right around 35 Hz

A 4" port would be ~24.5" long so won't fit.

But yes, you are correct in that they won't work well sealed.

Alright thanks! I think I found someone to build a box with fiberglass too get the proper space and tuning. Do the SA8's like a lower tuning? I was thinking around 31hz, from my experience that is my favorite frequency. I guess since it will be with aeros it won't be hard to raise/lower tuning if they don't like the lower tuning

The SA-8 v.2s work VERY well tuned down low, yes.
