Ok so I've recently acquired a pair of Polk Monitor 12. Before getting them, I read all about how they are boomy. I didn't think it would be that bad so I got them anyway. Now that I have them, they are boomy. Now I'm trying to see if I can tame them a little bit.
My pair have some one inch risers on the bottom of them. I don't know if this is original or not. Would it be better to try and raise them off the floor a little bit more? Also, last night I got bored and took out the passive radiator. I was surprised to find no dampening material. There was some up behind the four 6.5" drivers. Should there be some behind the radiator as well?
I also found out that my cabinets are not properly sealed. When I press and hold the radiator in, the 6.5" move out and then start to come back in. Is there any good materials to seal the drivers back in. I have used a glue in the past, but I don't want to glue all the drivers back in.
Finally would these speakers benefit from crossover recap? When I had the radiator out, I could see they had a manufacture date of sept. 1990. I know people have benefited from recaps from speakers from 70's and 80's but not sure if these are "ready" for it.
I'm up for any more suggestions on how to getting the most out of these. Thanks!
