well, I picked up a 410xl cab used a few weeks ago and I think I may have blown two of the speakers. My fault, I was running too much power through it and pushed it too hard for some high power gigs this week. Now two of them have that 'torn cone rattling' sound, I took everything apart to check for loose connections or something but everything looks good, just that sound on two of them. Anyway, I may just replace all 4 speakers, I already know someone that will buy the two good ones from me so at least I can recoup something for my screw up. Can anyone recommend a speaker that will work in this cab? I know that the cab is probably designed for the ones that are in it as far as porting and size goes, but I have had some success in the past, such as putting a pair of emminence deltas in a trace 210 of mine that sounds great now. Just looking for some ideas of four 10s that might sound good in this cabinent, with a higher power rating if possible. This was the older 410xl with the 8ohm 100 watt Hartke speakers with the power rating on the back of the cab of 240 watts at 8ohm. I'm thinking maybe 4 of the emminence gammas or deltas?
