So I got this free Ampeg 410HLF cabinet and it was pretty much gutted. No speakers, horn or back plate but the cab is pretty solid otherwise. I got a deal on four Eminence BP1020-4 ohm speakers. The cab is ported on the bottom and I'm thinking I might not even use a horn so can I just get a simple back plate with one jack and wire up the drivers to it? Maybe just fill the hole where the horn should/would be? For now, will be pairing a 4-ohm Ampeg PF350 head with this cab. Any ideas, suggestions? Thanks
