i have been pondering building a tuba 24. don't need it by any means but... the thing is how to make it work with my rig. i know the optimal thing to do is to biamp with a crosover and a stereo amp or two bridged amps. i don't really want to do this cause basicly it's a hassle. i wouldn't use the tuba all the time i'm sure, so i would have to rewire a speakon connector every time i switched configurations plus put my crossover in my rack (it's already full so get a new rack) plus haul the tuba around. what i would like to do is maby find a passive crossover for the tuba with a high pass out so i could run one signal and power everything. then i could use the same cable with either configuration, adding a jumper from the tuba to my current cab when i wanted to run the tuba. would this work? does anyone make a crossover for such an application? what would be the resulting impeadance that the amp would see (4 ohm tuba +4 ohm cab) what are some potential problems of such an endevour. btw although i know a lot about bass gear, i don't know a lot about passive crossovers, so if this is impossible go easy on me guys.
