Air Chamber question

[bgaff45]

Hello so ive almost got everything planned for the build. The last thing I need is a box design. Im running two sundown zv12 d2s on two crescendo bc3500 and the box will be tuned to 30 hz. Each sub will have their own amp and will be wired down to 1 ohm. I will be gain matching them. My question is is can I put them in a common air chamber or do I need to put them in a dual chambered box? Ive seen some people run 1 amp per woofer in a common chambered box but other people say its bad for the subs because of bass cancellation and slightly different signals coming from each amp. (I also know the risk if one sub blows in a common air chamber the other will most likely follow). Other than that risk, What should I do and why? Also do dual chamber sound any different in dbs or sq compaired to a common chamber? And whichever design is best should I go with a kerfed slot port or aeroports and why? Sorry about the length I searched the forum and couldnt find a question similar enough to mine.. Any information or tips would be much appreciated. Thanks.

ps. I will not be building the box. But I just wanna get everything on paper before I get it built if that makes sense.

give them time, some come on here late..

for pure loading purposes a center chambered port is better than a Slot L port in the first place when you run two subs. That equates to dbs directly. So yes do a centered ported box.

Why gain matching? You can strap them

Series those 1 ohm subs to get to 2 ohms then strap the amps... same power and only 1 gain, SSF, and lowpass to adjust... amps still will see 1 ohm each...

They are dual 2 ohm. Sorry to have left that out

So aero port? in the center? And what about dual chambered or same chamber?

Haha all good thanks

Perfect!.. OK wire the subs to 1 ohm each (parallel)... then wire them in series to attain a 2 ohm load... then strap the amps at 2 ohms... Perfect!

Okay now Im confused sorry, how would i wire them in parallel and in series?

So present a 2ohm final load and strap the amps. That will have both amps at 1ohm and no need for any gain matching. One amp acts as the master, and the other is its little b*tch.

Gimme a sec... I'll find a diagram and post it... It's easy...

Okay i get it now. Had to look up a picture of the wiring diagram. So basically both amps act as one putting out one ohm power to the subs wired at 2 ohms. And then in the same chamber or dual chamber
