I'm building an 2x10 8ohm speaker cabinet for my Showman amp to try out and am considering combining the Eminence 10516 and a Celestion G10 Vintage in the cab. Seeing as the Showman is an 85w amp, I don't believe I'll ever turn it past 3-4 for volume. Is there anything I need to look out for when combining these two speakers? Plan B for me was to just get two Eminence 10516's and call it a day... but where's the fun in that. Is it crazy to even consider combining the speakers?
