Fitting a 12 is going to he hard enough, let alone another 1.5" of diameter.

I'm sorry to everyone for taking this thread another direction, but I have a question for you. I'm basically making a box that is similar to the JL Audio Stealthbox in dimension, volume, etc. A friend of mine swears by RE Audio subs and we initially started out w/ an REx 8" DVC 175watt, and it fit fine in the box, but it sounded like the voicecoil was literally bottoming out just when it started to sound good, so I returned it. Now we've decided to move up to the SRx 10" DVC 300 watt. I'm running an MTX JackHammer JH300 monoblock 300watt amp, so the SRx is a better match for my amps power, or whichever sub I chose based on your reply.

My question is, should I really reconsider, based on your opinion, to stick w/ the RE sub (i've got an SX or MT 12" being run by an MTX 81000d in my 740iL, sounds awesome) or should I consider switching to the Pioneer shallow mount? I realize that with as small as the box is in the X that it's never going to be as loud as my 7, but I wanna make sure that I get the best sound possible within my budget. The RE and Pioneer are around the same price and the mounting depth isn't an issue, so am I better off w/ a standard subwoofer that is DVC (allowing me to pull more power from the amp) or this shallow mount? I've never heard a shallow mount, and no one lives near me so I can get an idea of how it sounds. "Great bass" is relative to the person who listens, so what is good enough for some might be puny to others, ya know.
