I have a @ 1991 Ampeg SVT-410e with the original 86-032-01 speakers. I am building a 210 cab to match a single compartment to give me a 5.33 ohm modular 610 cab. I have 1 Electro-Harmonix 10SVT speaker and need to find another or an equivalent. My question is will having an Eminence B810 in the same compartment as the Electro Harmonix 10SVT or one of the stock speakers sound/work okay? Would I be better of getting a new Ampeg Replacement Speaker I am leaning towards the Eminence B810 because they are fairly affordable and should be availabe for a long time. I can't afford to buy 2 new B810s right now, or I would. Anyone know where to find another Electro Harmonix speaker? I have a 4x8 cab of Jensen Mod 8-20s that I wired in Series for a 32ohm load that takes care of the high mids. In case anyone is wondering they work/sound very good. No crossover needed, at least with my setup Thanks for the help!
