Two 12s vs. a 15 & Two 10s

400 rms would be great for a single subwoofer setup if you are not trying to get loud

Anyway back to reality, three tens or two twelves. I worked out the cone surface area for the Kenwood W3011 and W2511 that I'm thinking of using, and the 2 12s come in at around 846cm2 while 3 10s are around 798cm2. Don't know what that is in inches, but anyway it's pretty close. The tens however would be running at 1.33ohm vs the 12s at 2ohm so they would be drawing a bit more current than the 12s from an identical amp. Would this more than compensate for the lesser cone area I wonder.
If I went pure SQ, I could get away with like one really good 10 yeah?

Absolutely, but you would have more options in a 12". For the power you have to work with I would focus on having more cone area per motor, more than just having more cone area, and look at the driver's efficiency, try for something > 85db @1w.

I really do think that you will have a hard time getting loud and sounding good with only 400w. There are things you can do to make a sub louder, and things you can do to make them sound better, but doing both usually means doing the things you would do to make it sound better (flat tuning with cabin gain + eq) and then pumping lots of power to it and adding more drivers. I would pick either SPL or SQ and stick to it.

I thought I made it pretty clear when I brought it up that the 8/10/12/15 thing was a meaningless tangent, I am NOT considering putting that in my car. But a lot of people here seem fixated on that idea so by all means continue to discuss, however the purpose of this thread is to decide on a setup for my car.

Thanks Sexie, now we're getting somewhere.

How would a Kicker L5 10"do on SQ duty?

I recommend an IDQ v3

This has got to be a troll... you just can't say this many totally backwards things in such a short time without trying to.

I don't have much experience with kicker subs in sq installs, I have a friend running a CompVR 10 sealed and sq wise I guess it's ok, but no where near what my revo 10 was sealed, I wasn't impressed, but that isn't a L5 either so I really don't know.

I really like the sound of the Infinity Kappa Perfect line, but they are full on SQ and just don't get loud.

Trey thanks for posting up the images of the kenwoods. Sure there are much better subs out there, but is a good quality sub really so much better that it can beat 3 midclass subs of the same size. I can get the Kenwoods at $40 each here and they handle a decent load and look much better visually than any budget sub I have seen, but yeah nothing is set in stone at this point.

IDQ > 3 of those kenwoods

It all depends on the install, but not many people that have the knowledge and time to spend on a great install are going to put the effort into a budget sub.

but for pure sq IDQ > 10,000 Kenwoods

Why I mention the L5s is because the hype is that the 10 performs like a 12.

I'm in New Zealand, there are no IDQ or RE dealers here, I would have to import, and that is gonna cost a ton on postage, not to mention those subs are probably horrendously expensive in the first place. I'm restricted to Kicker, Cerwin Vega, Rockford Fosgate, JBL, Phoenix Gold, Alpine, Pioneer, and some other crap brands not worth mentioning, such as Sony.

I don't even think I can get JL local, and I don't mean in my city, I mean anywhere in the country.
