I am looking to bi-amp my current rig using an Ampeg SVT 200T. It has the capability to actually bi-amp and I do understand most of that. My issue is that I cannot seem to find a proper cabinet for the high pass. All of the cabinets I research are full range cabs and it seems to be a complete waste to get a cab thats more designed for the lower registries (300hz and down) and only use it for it's upper registries, an area most bass cabs are not really optimized for. Rolling off the upper tones on the lower cab are not as much of an issue as most 2x15 etc are really shining in those lower areas and I don't feel like I am wasting much. Bottom line is for the upper pass should I be looking at using something other than a bass cab? I actually tried sending the upper pass into a Fender Twin Reverb but found the tone to be horribly suited to bass applications. Should I perhaps be looking at PA systems enclosures? One of the reasons I am looking into bi-amping is because I have had fun messing with effects on the separate cabs. I also like to overdrive the highs a bit and keep the super thump in the lows.
