Sound Q - is this box too small?

[OzzieComm]

Hi All, I have this box with port, will this fit the SQ 12" HDS312 or should I put the 15" (of the same flavor) instead,
looking to run off the SQ Q1-1200D

Thxs all.

you will want the 15. That box is too big for a single 12.

and btw, .3 subwoofer displacement is massive for a single woofer, probably the only one that big is a 21 or 24in woofer. 15s are generally .15-.2 or so a piece for what it is worth.

mate, thanks for the heads up on the woofer displacement.

perhaps 2 12's then?

2 12's would probably work. Would have a bit of cone area advantage over the single 15.

edit: well, wait a second, your port is WAAAAAAY too small.

For 2 12's or a single 15, i would use 1 PSP 6" aero port with the flared ends.

[OzzieComm]

Chev, Thank you.

OK, lets say I do 2 12's and a aero port (aero port like this?) sound good?

[ChevyBoy95]

that is the exact port im talking about. Maxes out at 17" long, so just either use it full length or cut it down to whatever needed.

Should sound great and BANG down low.

If you keep your same volume and make it say 15" or so long, will give you a nice daily tuning of about 34-35hz.

Only thing im worried about is the flares are ~9" in diameter, so the internal flare might hit one of the magnets. One way to easily avoid this is invert them [the subs].

[OzzieComm]

Hmmm, good point fella, mate thank you for the info.

time to get the Credit Card out.... 2 12's I reckon

Building with 5/8th's material with that much power is gonna cause some enclosure flex.

not if he braces it correctly, and it is 1200w, you could build the box out of 1/2in if he wanted as long as it is braced.

Agreed
