Does anyone know what types of crossovers are used in some of the bass cabinets that have a single 15" driver and a tweeter (horn-loaded hi-freq transducer) ? Some of the ones I've been looking at are the Hartke cabs, such as the VX115, although I've seen numerous other cabs that have this type of setup. I am thinking this type of setup would work well for me, because I like the idea of having the tweeter handling the extreme highs. Any ideas, opinions, or suggestions would be very helpful to me. Thanks for your help with this.. Mag..
