That TC-Sounds 12" driver I used for $369 is not a crappy driver. It's high end, and probably better than anything your going to get in a MFG made subwoofer under $2000. That's what is nice about DIY.
You'll notice that driver I used is one of the most expensive drivers Parts Express carries too. You can choose a cheaper drive around $200 for a 12" that would give you 90%-95% of the performance for a good drop down in price. I actually found it by sorting by highest price
$369 for a DIY 12" speaker is by no means a good deal, or cheap. I wasn't worrying about that based on your budget of $2000 because you'll never spend that even with a really nice high end amp and going all out on the enclosure. I'm guessing you won't break $1000.
There is just no way you can buy a subwoofer for $1000 that would compete with a DIY subwoofer for the same price. I've yet to see it. The beautiful thing about DIY is you get what you want. You can go flat to 12hz if you want. You can go really loud to 130db if you want. It's all up to you. Some drivers work well in big boxes, others in small boxes. Some go loud, Some go low- some work well ported, some work well sealed. Sky is really the limit.
Based on you not needing maximum SPL and you wanting a small box and really low frequency extension I just thought that 12" in a 3.0 cubic foot box would work well. You could easily enlarge the box and increase the tune frequency to say 20hz and make a totally different type of subwoofer (louder) if you really wanted. Just seemed that is not what you want. I doubt that $2000 sub is making the same SPL at 12hz as that one I modeled. 12hz is no joke for any subwoofer at any price. That sub I think would be well over 100db @ 12hz
Impressive for a small 12" sub.
