Well I misunderstood, thought you were taking out the midrange a little too often. Cool.
Have you any experience with their woofers ? The 15NBX100 or this big 18''=18DS115 .
I was always blowing the diaphragm's in my A-7'-500's (modded) until I went bi-amp with the Pioneer 850 x-over.
Thinking about tri-amping them. the big B&E 18" might be a way to clear out the spiders.
This is my shop system. too much WAF to move them into the house, but I'm working on it. My sweet wife loves music and doesn't mind
the tri-amped Dahlquist system in the new house room. I guess she thinks the Altec's are ugly.
