I've got a pair of Wharefdale Pro Lix 18SB speakers. The cabinets are in great shape, but the subs are done. I'd like to replace them with a set of Peavey Black Widow subs (mostly for the replaceable basket options, and the fact that I've always had good luck with Peavey equipment). That said, I'm wondering if anyone could help me figure out which Peavey sub would most closely match my cabinet dimensions.
Note: I'm also planning to bypass the internal components and simply run them through an external crossover. Is this a bad idea? If not, any suggestions on a matched external crossover would also be appreciated.
Thanks!

1. Take the blown driver out of the box.
2. Measure the inside HXWXD in inches. Multiply these as an example. 32X18X22 equals 12,672 square inches. Divide this by 1728 to give you the square foot the box is. So this examples box is 7.3 square feet. Remove 10 percent to take in account for handles/braces and speaker. I'd down size this box to 6.5 cubic feet to have easy math.
3. Measure how wide the ports are and how long.
4. Download WinISD Pro program and learn how to use it.

Enter a box with the above measurements and ports to find the tuning frequency of the box.
Now go through the entire Peavey line of 18 inch drivers and find the one with the best TS parameters to work best in this box. You'll want the driver with the deepest response, most control at box tuning and the power handling you need.

You could do all of that and still get just average response or buy 2 of these. http://reconingspeakers.com/product/wha ... xc-woofer/
