In a quest to make my HeathKit AS101's even better I have rebuilt a set of 908 drivers into 902's. I believe these will be a little hotter than the 806 drivers that will be in there currently. My game plan is to eventually cross them over at 1200HZ like the Model 19's but in the meantime can I use these 30904 attenuator's with the stock crossovers and the 902 drivers?
My understanding of the 30904 attenuator's is that they knock down the mid frequency's so that the HF better matches the mids.
They also have a zoble network for the woofers, should I worry about hooking that up at all?
Reason I ask, there was a set of clean looking 30904 attenuator's on e-bay this afternoon that was just listed for 35 bucks. After a quick bit of research I purchased them but I'm not sure it will really do what I want to do.
Thanks for any input.
