Re: My old Dharman is down, any advice
Just thought I'd give an update. The Dharman is back, with a vengeance. The plexiglas worked great. Got everything right on the first one, didn't even need the back-up piece. It did take a little work and the MDF would have probably been much easier. It did take a bit of work to get the driver itself sealed. I was really surprised how much noise a tiny leak can make even with two large ports. Apparently, when they build these things, they don't use any pilot holes on any of the screws, so after taking out the Shiva putting the new driver in and taking it back out again, there were chunks of the MDF missing around the edge. It's so torn up that I think half of the screws stripped when I turned it so that I was in between the old holes. I finally just went around the outside edge of the new driver with silicone because I was too concerned about pulling it out again. I made a bit of a mess of things, but it sounds great. I'll have to start with a new box if I ever have to remove it for any reason. It was definitely the amp causing the problem. Now I just need to make a 3 inch deep grill for the front. The new driver sticks out a lot more than the Shiva. In fact the current grill actually sits on the surround when installed. I've got some ideas of how I might just make the current grill frame deeper and recover it.
Thanks for all your help Robert!
