Fixing up old subwoofer? - Page 4

post #31 of 38
If you got that much bash 500 watt, ED subwoofer and put it in a sealed enclosure and your good to go!

Get a pre-fabed box that will work for about 60, 190 for the amp and http://www.edesignaudio.com/product_...roducts_id=784 sub I'm looking at and when you have the cash, let me know and I will help you turn it into a earthquake from hell!

Note: GOOD GOD! That box you posted in original, don't use it as it is WAY to big for almost all 12" subs. I hope I helped in some way and enlighten you to destroy your house with this setup as a 15" about 5dB more from 30 Hz and up and 20 Hz and lower is about 4dB more. This is a 12 cube box for the 15 and mine is a measly 2.65 and lets not forget getting a slot port for the ported 15" will be a PITA.

I decided to save up a little cash to finish this long lost project, and my current budget is around $200-$250. The drivers in there now are some old 12's I got from a garage sale, all for a grand total of $5. They aren't the best, so my first order of business is replacing them.

Anyone have suggestions on some decent subwoofers that would fit my budget? Right now, I'm looking at the Dayton DCS385-4 for $100 each.
Your an ideal candidate for a Tuba sub from Bill Fitzmaurize!

Tuba Home Theater Sub

The plan is $15 bucks.

PS the design uses a Dayton RSS390 HF4

cut the box in half and smack two 12 inch anythings in there and use a 300- 500W amp and you should be good.

It is a very generic problem.
6cf3 is a ton of space even for a 15-18.
placing two 12" subs, even if you port it, in that box is unnecessary.
A general rule of thumb is that 1.5-2.5cf3 is all a 12" needs.

And like I answered in this thread weeks ago.....

He needs to pick drivers before he can design a proper box for them. Some will work better vented, while others sealed. And just saying "two 12 inch anythings", that could mean Dual 12's from Wal Mart even.

Two 12" anything from wal-mart will do fine for a while in that GIANORMUS enclosure, they will for sure play deep and sound good at low power.
