So I am in the process of buying a new amp and cabinet. I have decided on the Orange Terror BT500 amp. But as I am spending $800 on the amp that doesn't leave a lot in my budget for a cab. I'm looking for a cheap but dependable 4x10 cab. I'm trying to spend no more than $500 on the cab and I'm not opposed to buying used. My ideas so far include an Ampeg Portaflex 410, Ampeg 410hlf ( both used) or a Fender Rumble 410 which goes for $300 brand new. Any one with any experience with these cabs or any other suggestions to help a fellow bass player out would be appreciated. I play a Fender P-bass special (with the P and single J-bass pickup). I play in a punk band that gigs very frequently so portability and light weight are pluses but tone and punchiness are the most important factors for me. Also the amp I'm getting is a 500 watt amp this is my first time buying an amp and cab separately this may be a dumb question so sorry but how close does the watt load of the cab and amp have to be? The Fender Rumble cab is rated for up to 1000w so will using a 500w amp not work with that? Or the Ampeg 410hlf is only rated for 400w so will a 500w amp blow the speakers? Again sorry if I'm being a total newb but any help and suggestions would be much appreciated.
