hello all
this is my second pair of Infinitys, upgrading from a set of RSb. the RS3b that i got are in great shape, cabinets, grills are perfect, diffusion foam is all together, all original parts. the foam surrounds need to be replaced.
so i ordered all new foam surrounds, caps, potentiometers, binding posts, wire, etc.
so far i have tested all the drivers with a mulitmeter (all good). i removed the woofers and removed all the old foam and glue (2 +hours each driver!). i added a bit of Dynamat to the backs of the baskets.
pretty sure i've read through all the 'RS3b, RSiiib, and RSlllb' searches on here and learned alot so far.
i have a few questions about things i can do next while I'm waiting for the parts to arrive.
a) should i reseal around the inner cabinet edges with silicone?
b) is it a good idea to add some acoustic foam to the inside walls, if so what size? (3/4" high density?) and glue it to which walls? (If i add foam do i keep the polyfill inside or use them together?
c) should i add some internal bracing front to back or glue some ribs to any of the sides? if so where in the cabinets and what size? (block off the EMIT and Polydomes maybe?) (i have a sheet of 3/4" MDF)
d) is it worthwhile to glue some felt or foam to the inside of the woofer baskets?
i want to make them as good as possible the first time so i don't have to worry about it in the near future, however i don't want to go overboard and kill the sound..
thanks for you help!
