You could port it and adjust port sizes for some added dB, FR, and make for a very cool way to build a variable parameter subwoofer. I have a sub that I bought plugs for and adjust the ports manually now and then. Kind of fun. I prefer the sealed sound though, but sometimes it's nice to have the +4 to +5 dB below 30 Hz for free at the expense of some musical sound quality.

Maybe even internal bracing and sealing, it's been awhile since I saw the inside of the cabinets, can't remember if their caulked or not along the seams internally (that helps prevent air leaks).

Anyhoo, for the cash, those are just about the best subs I've found still, in a pre-assembled, or kit form. Adire use to have a pretty affordable model that was impressive too but I think it wasn't worth while to them. Those should keep you satisfied for awhile.

What subs do you guys have to compare to the 15" Titanic? I get a lot of PM's from newbies and the like here (probably resulting from me shilling the Titanics so shamelessly at times) asking me about the 15" and what commercial models it compares to. My best commercial sub was the Paradigm PW-2200, but the 12" Titanic whooped that. I don't own the 15" Titanic and have only spent a few hours a few times with one - enough to know it's awesome but not make a good comparative guess..
I have the Infinity Primus PS-12. It's a 12" rear ported sub with 350 w/rms. It was OK but was maxed out to fill our 700 sqrft main room. I was worried that it would give out at that level. It does a fine job in the bedroom now, but you can't really compare it to the MKIII. The MKIII goes lower & louder and does it with a much tighter sound. I love the sealed sub sound. I would never port it. Even at below 1/2 volume it fills every bit of the main room+, so it doesn't really need the extra boast. I'd just have to turn it down anyhow.

So, how's it going down under? When are you and wifey coming back?
