I recently got an ebs 4x10 cab with two blown drivers. On the upside, I got the cab for free I contacted EBS, and they're selling replacement drivers for the low-low price of $200. each. Plus shipping (from Sweden). So I'm thinking of loading it with either 4 new drivers, or 2 new ones plus the working EBS drivers. I've considered EBS cabs a bit bright, or brittle even, so it'd be nice to find a reasonably priced driver that's a bit smoother. Guitar dorks do this sort of thing all the time, but I haven't heard much about bassists playing with drivers. Any suggestions? I'm talking about a ported cab here, not an open back guitar amp, so the drivers have to be similar to the EBS ones I'm replaceing for them to work well in the cab.
