why am i having such a hard time finding 4 ohm 15's? here's my problem: I want to buy an Eden WT-800, which is 400 watts per side into 4 ohms my thought is that i want to get a 4 ohm 410 and a 4 ohm 15 to get 400 watts into each one... finding a 4 ohm 410 is easy, but as for the 15: eden doesn't make one aguilar doesn't make one avatar doesn't make one swr doesn't make one ampeg only makes one 4 ohm model out of the five or so 15's that they make is there some kind of problem with 4 ohm 15's which prevents companies from making them? are they unstable or something? i don't understand why no one has them now, if i buy a WT-800 and use it with a 4 ohm 410 and an 8 ohm 15, how much quieter will the 15 be? since it will be getting half the wattage as the 410, i assume it will be pretty noticeable, which i don't want i'd appreciate any help you guys could give me! PS, does anyone know of any makers of 4 ohm 15's?
