Hey GlassWolf, have you sold RE MT series? If so do you have any spec on it? I can't seem to find the frequency response, real rms power, and magnet weight. RE's email support is down and those guys are not pickup the phone nowdays.
nope don't have any RE spec sheets laying around here sorry. magnet weight won't mean much though as the weight and magnet material are just factors in creating the BL of the driver, and with XBL^2 you have multiple short gaps to control driver movement anyway so the magnet structure isn't traditional to begin with. I'm not sure the MT even has a spec'ed power handling, considering it's purely for SPL, offered in quad coils, and has no factory warranty due to the nature of it's application. Being a sub though, freq response will depend on the diameter of the sub, but generally flat to around 100Hz or so at least (within 3dB) and you wouldn't cross over a sub like that higher than 80Hz anyway.. pretty much ever.. so response won't matter much, and if you go vented, the bottom end of the response isn't as vital as the Fs anyway since below the tuned port frequency, the sub is going to roll off like a volkswagon falling off a bridge.
