Hi,
Thanks Vinnie for all you have done and I really appreciate it.
Getting to the felt, I will try out a ring of some sort and can have them die cut. I will look into it and have them made. This will be an in the shape of a doughnut and will have a PSA backing. Easy to install.
All the new stuff including an OB alnico based speaker with powered bass is a reality and more to come. I'm also looking into twin driver subs and the 6" full range is whizzerless.
Thanks,
Louis
