Hey guys I have 2 peavey 358s PA speakers. I used them for a time as a light weight stack for smaller gigs an they worked fine. These cabs are 8ohm and are rated for 300watts they have a 15" speaker 8" speaker and a 4" horn. Cab is 3/4" plywood on the back it has inputs for low and high and full range. I would like to remove this crossover? And the speakers and bassiclly make this cab sort of a super cab of sorts but want it to be able to handle 500watts or more. Obviously i need new speakers but need suggestions on what to get to make this whole thing work as i am a amp novice what ever i needed before i just bought. Also does anyone think i would need to section off the 15 from the other speaker. Right now inside the cabs there are sort of half walls in it that stick out about 4" from the front of the cab to the inside but nothing is really separated. I hope to add pics soon but am at work right now and cant. Thanks for any input in advance.
