Im having a hard time weeding thru everything to find the best of the best woofer for my application. It seems as if i get a different answer from everyplace... So ive decided to ask seperate questions and be more specific in my application goals (and poll as many peeps as possible). Box will be ported using 6" areos. I want a pair of 15s that can accuratly reproduce all bass (especially the lows) @ a 4 ohm load on my amp. At that power i want to be able to go to an sq comp and win. But i want to be able to take it down to 1 ohm and run like meade... subs must be able to handle the power at 1 ohm and sound as good as possible. Daily is where im mainly concerned with but im not sure on how much power i will run for daily (1ohm or 4 ohm) but if i get a quad coil woofer i may just run it at 2ohm but im not sure.

below is the sites for the woofers in question

If you're looking for all out loud, go with the MAG. If you want loud and the same SQ...at 1/2 price, go with the Q.

The Mag does a lot more than just get all out loud, though it's good for that too

To my ears, the Mag is a clear improvement over the Q, but like you mentioned...that improvement comes at a cost. Whether or not that's worth it to you is going to be up to you.

A pair of Mags can't be wired to either 1 or 4 ohms though. They are D2 only. I like my XXX a lot but unless you can find them in D4 config, you will have the same prob as with the Mags.

I'd probably go with the MAGs. They'd probably get louder than the Qs.

helo is right though, unless you're giving them each their own amp, you're not going to end up with a 1 or 4 ohm load.

If you can afford the MAG, I love that sub. The Q also got a vote from me.

looks like the SI mag is out due to D2 only that makes it a lil easier but not really... so should i try rd audio and see what there worth? go with the Q for sq reasons? take the DD and just have sq on the back burner? or try and find a pair of re XXX's which probably wont happen

If the MAG is out, then go Q

the q at the lower power for sure. the 9515 at the 3kwrms easily wins, IMO. personally, for what your after, i think the dd sub would be your best choice. build your box with a changeable port and i don't see why the dd can't provide enough sq/ output to help one win in both fields. especially since your going to need a strong front stage in order to win sq or really good output from the subs to make up the points.
