After years of downsizing, I needed a bigger rig for some summer outdoor shows. With limited income from these gigs, I took the cheap route and bought a GK 800RB and 2 GenzBenz cabs on Craigslist ($450 for the head, 410 and 210 cabs, although the 210 only had one speaker.) The 410 sounded great at in-house volume when I checked it out, but my first outdoor stage proved the 410 to have a blown speaker. I bought 2 Eminence BP102s to at least get the 210 running, but the speaker port is too small for the Eminence frame - the cuff sticks out, preventing the speaker to sit cleanly in the port. What are the best options for speaker replacements for the discontinued GBE 1040-8 speakers that were in these cabinets?
