I have 2 Focal 13" PolyGlass Subs and i was wondering what is the best way to make boxes for them.
previously i had just used an old box and modified it so they both could share a single chaimber,
now i made two seperate boxes for them.
i was just wondering, which box will give the best performance - output level. (no bandpass'es, or ported boxes please)
i guess it leaves me with the real option of 2 seperate boxes, one chaimber for both, or one box with a divider.
any help would be appreciated.
thanks
Chris

It doesn't matter if you have a common chamber, divided box, or 2 boxes. All separate volumes offer is the ability to take one woofer out and not affect the other one.
If you wanted superior performance, you would port it [img]graemlins/headbang.gif[/img]

im sayin if dukk recommends u port the box, its probly worth your while to port your box....
im trustin someone whos been doin this that long over a piece of paper, my 12s are supposed to be in like a 2cuft. ported box, its closer to 5cu ft. (i questioned, but trusted the guy who designed it,) theres no way my system would be puttin up the numbers it does if i had gone by what PPI recommends...
just food fer thought...

I have heard them in a ported box, and i was not to keen on the sound, at high volumes they would get a little bit of a flapping sound. so from what the focal reps tell me, and the sounds i heard from a ported 33v2 imo i would never want to port these drivers.
i am a believer in porting some drivers. i have had many ported box's that have done me well, just not in this case.

i'd try it to. espeacially coming from dukk. i was told to make a 2 cubic foot box with a port for ours. i made it 32 cubic ft. with a port the size of nebraska. and we hit a high number with that. you should go into the db drag website and the iasca web site and look at event photos of what high db hitters hit, and get a feel for whether it should be ported or not. good luck

you want great focal box builder, get a hold of dave at speaker city in vancouver.he's a genius when it comes to box design. we use his services extensively. they carry focal too, so most likely he already has a box design made. 604 736 2077. tell dave that pat @ trends sent you. he's just a phone call away good luck
