Plain old Elmers wood glue. And clamps. Lots and lots and lots of clamps. Harbor Freight is your friend.
Also this thing rules:

I am sorry, SVS and musical typically are not in the same sentence. They do have certain ones that are musical, but their typical application is simply loud, thumping low for movies (i.e. explosions, etc).
Anything larger than a 12 will be too big to be very musical. 10's seem to really be the sweet spot unless you listen to organ music (unless you are using 4 or more which are properly tuned). If you listen to organ music, the only things I can say will do it are servo controlled 15's, but you are talking big money for that.

Anyway, after quickly reading through the thread, it appears you are going DIY-ish with a Dayton RS kit. Good choice.
Here are two more options if you haven't purchased already though:

O The last one I got was the 2.1 Logitech Z series (cant remember the number), and it pales compared to my $200 cd system which is 10 years old.
OP, may I ask why you are particularly interested in getting a good sub? If you are just going to use it for music and not games, I think a 2.0 system will actually give you better overall sound quality unless you are willing to tinker with your sub settings alot. Or maybe I've just had bad experience with 2.1 systems. The last one I got was the 2.1 Logitech Z series (cant remember the number), and it pales compared to my $200 cd system which is 10 years old.
How about a decent pair of studio monitors, e.g. from M-Audio: https://www.storedj.com.au/products/MAU-BX8ADELUXE2 ?
