car subwoofers 1000w a peace and look at the db though 92-94 is a good range 2-10 is the same as a 20 inch speaker and use a horn mid/tweeter with crossover cap if you like a little high in your sound :)
I AM GOING TO USE A SELENIUM D250-X 1" GWPHENOLIC HORN DRIVER AND A DAYTON HO8RW 8 INCH ROUND WAVEGUIDE 1" THREADED. AT PARTS EXPRESS. :) THE HORN DRIVER IS 400-9,000 NO CROSSOVER NEED 150 WATTS 8 OMHS BUT I WILL USE A 6DB OCTAVE CROSSOVER TO GET IS AT 600HZ. :)
this was the best cab they ever made. peavey will tell you this to. they only made them for a short time then they stop making them. that is why people love this cab :)
THE cross over is 600hz on the 1516 bass cab they are a mid bass full rang 8 inch speakers my guess is about 97 db 78hz-4000khz the 15 inch woofer is a black widow speaker the max power of this cab is 400watts at 4 ohms.
