I am looking for a 3way active crossover that will allow me to set one of the high pass filters high enough for a tweeter. On the Phoenix Gold web site they have a MX3i which looks like what i am looking for but BBG dont do that one and i cant find much info on the net about or anywhere that sells it. BBG sell a PG TX406 which looks like it might do but it doesnt have any knobs in the pics i can find so dont know how it is adjusted or if it will work with a tweeter and i cant find much info on this one at all. So if anyone knows of these products or products from other brands that fit my needs then please let me know.
