Built my first ever subwoofer box!!

[talnlnky]

congrats on making your first box.... I remember the first box I completely designed and made myself.... (was actually a box for SPL)... I've learned a lot since.

I like how you did the slot port, that helps with bracing, but it looks like you could've benefited from having a bit more internal bracing.

Good job on picking a decent tuning frequency... it should give a good amount of bump, yet at the same time is tuned low enough that hopefully it won't sound sloppy or too overbearing. I often found that 30-35hz was the optimum comprise between SPL and SQ for car environments.

last thing, if you have access to a router, taking a round-over bit to the port edges will help reduce any chance of port noise, tho it looks like you have more than enough port area (without me crunching the number) for those two tens.... I remember running similar port area for single 12" subs with high power/high excursion.

again... good job... your are close to being bitten with the box building bug.


Oh, and on the equipment side of things.... I always have to put my signature plug in for you to not run rear speakers, and to spend that money on either better fronts, more deadening, larger cable, or anything else as rear speakers add a lot of cost, but add nothing to the SQ realm, and very little to the SPL side of things.
