Default Do I need to dampen the back side of the baffle?

In other words, around the driver? I have the back wall, side walls, top and interior panels dampened, but I wasn't sure about the back of the front baffle.

And by the way, my Dremel Multi Max saw did the trick chamfering the baffle! It's all good now

Thanks,

Tom

Default Mineral wool to line the walls?

Since I already glued it in place, I guess I'll find the answer, but I thought I'd ask...

The company I work for manufactures "fire blanket" for use in building expansion joints. The inner lining is made of mineral wool, which I can get my hands on, in unlimited quantities, 1" thick. So, I grabbed a roll, split it into 1/2" thickness and used it to line the walls of the cabinets. I assume this will accomplish what it's meant to do ... break up the standing waves in the cabinets? I know the recommendation is for the denim insulation but this was abundant and readily available. It sure looks good (I'll post a pic tonight). Any thoughts? I can always pull it off and glue in something else's guess (it would be a challenge through the top, but I think it could be done). What positive/negative sound characteristics should I listen for to determine if its doing what it should?

Tom

Default CHP-70 Gaskets?

I have the CHP-70 enabled drivers ... are there supposed to be a mounting gaskets with the drivers? I didn't receive any if there are. Just wanted to check since the Mark Audio data sheet refers to them.

The absorption characteristics of mineral wool and the recycled denim are reasonably similar. I doubt you could hear a difference between equivalent applications.

Tom,

Check to see if the gasket is already stuck to the back of the bezel -- that is how i usually ship them.

If i forgot, then i will send you a pair.

Dave,

The gaskets are definitely not there. If you could drop a pair in the mail I'd appreciate it. I'll PM you with my address.

Thanks!

Tom
