Default Removable baffle and back panel sealed boxes for tests

I figured this might interest a few people, since it's a little bit different from the norm.

I've been putting a removable baffle on my last couple of enclosures trying to get the design worked out and refining it each time. The first one worked, the second was better and these are a little better still. The reasoning behind it is because I like large diameter, big drivers and they are usually heavy as hell. I've pinched a few fingers putting them in and removing them and also had plenty of screws and T-nuts strip out. It sucks. I figured this way I can yank the whole front off of the box and do whatever I need to do in there. The other reason is so I can use the enclosure in multiple configurations by simply making new baffles. I'm also going to have some removable bracing in these on the back panel. I plan on using these to test a whole bunch of things. Different drivers, port configurations, port compression limits, effects of bends in ports, port flaring, stuffing and lining effects, bracing effectiveness, dual opposed driver enclosure vibration cancellation, blah, blah...

I'll be building 4 total. The enclosures are about 270L (9.5 cu ft) internal volume after accounting for bracing and driver displacement and are 23.75x 23.75x 37 which is about right for a the drivers and amplifiers I'll be using in the finished system. I'm using 3/4 BB ply single thickness for the sides and bracing and double thick for the baffles. 2x2's are used for bracing and the baffle mounting foundation. This is the progress on the first 2 so far.
