I've been meaning to start a thread on my latest subwoofer project but up until tonight I hadn't actually stopped to take any photo's.
The subwoofer is a sealed 2.5 cubic foot box using the Adire Tumult driver. The walls are all MDF 1.5" thick (double 3/4") and the outside dimensions ended up being approx. 18" * 18" * 24.5" with 3" legs and a bottom base plate. As you can see from the photo's below I had some velveteen material left over from a previous project that never saw the light of day (masks for my projection screen) so I've used that to wrap around the sides. We cut out a 3/4" space on the corners so that the oak quarter round trim fits in flush and gives me a nice tidy place to end the seam for the cloth. The base plate, legs and bottom are all painted black and the top will end up being either all oak or a black MDF panel with oak accents around the edges.
So far all I've managed to do is seal in the driver and run some sine waves though it just to check for leaks etc and from those early tests it seems like a solid little sub. I'll post some more photo's once the sides, top and base plate are installed for those that would like to see the finished product.
One thing that I did that I regret was recessing the driver on the bottom. In hind sight given that its mounted on the bottom where no one will see it I should have left it mounted on the surface. Its not really a problem but given that the Tumult weighs over 60 lbs its a little difficult to get the beast out once you've dropped it into the hole for a test fit :B It also got worse when I put the legs on as they're butted right up against the hole so dropping the driver it for the final fit was a fun stop and start experience as the rubber surround on the driver kept riding up and not sitting flush on the bottom...I really should have made it larger then I did but its already much wider then what the cut out states on the Adire website which I can only assume is for the driver only and not the rubber surround (which was a PITA to fix after the initial hole as routed out)

)
Anyway I haven't had time yet to run some sweeps to see if that position is the flatest as it might just be a big peak that I'm seeing on the SPL meter.
