Not too noisy or too rattly. I'm just trying to make it even quieter and tighter. I'm installing McIntosh electronics with Focal speakers (the French do make some good things!). I added sound damping and foam panels inside the doors to make the door a better "speaker box."

I'll put together a photo gallery when I make a little more progress. If anyone is doing the same thing, I can probably help save some work.

One thing I discovered is that the doors are far from watertight - when it rains, water drips DIRECTLY onto the speakers. I'm fashioning a little umbrella for each of the new speaks.
