I've got a Fliptops sealed 4x10 cab loaded with Eminence Delta 10A 10" speakers. I'd love to swap them out at some point in time for neos, but I know swap speakers is much more complicated than simply picking a random speaker! Can anybody help to find a speaker that would work well with a dual-sealed cab like the fliptop? Its about the same volume as an Ampeg SVT 410 HE, but maybe 2" wider. Thanks!
