Which is louder? Series or parralel?

I have 3 12" Dual 6 ohm subs. JL 12W6v1's.

Question is- if I put them parralel @ 1 ohm,

Or in series (of sorts, kind of a mixture) @ 4 ohm, which is louder and more accurate?

I will be using about 1000 watts RMS at either 1 or 4 ohms. The box will be a divided sealed box for now, built to JL spec.

yea, if your puttin the same power at either ohm load, it should be the same

a thousand watts is a thousand watts

If you can get 1000 watts RMS at 4ohms then go with that, as the amp will prefer the higher ohm load.

Either a PPI PCX2200 @ 4 ohms or an Orion HCCA250R @ 1 ohm are the diff amps.

1000 watts at 4 ohms is high voltage, 1000 watts at 1ohm is high current.

Higher current equals greater heat, so i choose the PPI based on it won't need to work as hard to make the wattage as the Orion will.

If this is true then it also means mildly higher efficiency on the subwoofers part. +1 for 4ohm.

Thanks, that's a good idea, i like the logic behind it. Plus, the PPI is much cheaper than the Orion.

Still, even then I worry about cone displacement cancellation... Kina like when you run woofers in series in a one chamber box, except not as bad. Probably shouldn't. //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

Hmm //content.invisioncic.com/y282845/emoticons/up2something.gif.dd110ecf3ae4b76050d87598f2f8de7c.gif I like that idea too! Thanks for posting that, interesting idea!

Shouldn't be problem, I have done it without problems several times. Just keep the wires as short as possible between the woofers and use a nice heavy gauge (10/0 or better) for low resistance.

When I was young in the field (IE, last year, haha) it was pounded into my brain from somewhere that a DVC woofer went parallel for SPL, series for SQ. It could just be me convincing myself, but DVCs in series have always sounded a hint better to my ears.

Yes 10 guage, sorry for any confusion.//content.invisioncic.com/y282845/emoticons/blush.gif.99bc659ee2012b7d826165e26fb5eebe.gif
