Hi All,
Attached below are some pics of an internally powered cabinet I designed.
Pretty straight forward really... simple full range design with (2) 10" Selenium drivers and (2) 1" Vifa dome tweeters. They are crossed over at 3.2k with a first order crossover for a 6db roll off per octave. There is an L-Pad on the tweeters for any attenuation there if desired.
The cabinet is made of 3/4 inch birch plywood with finger joints for very strong corners. The dimensions are 25.5 wide x 13.5 tall x 13.5 deep. It is a sealed cabinet design currently, though I am not opposed to some ports in the front corners... not sure quite yet.
Completed it weighs in around 45 pounds or so. The corners are rounded over with 1/2 radius. All combined, there are over 120 fasteners in this box and there are none in the corners.
The power amp is made by Sure Electronics and is based on the Tripath TP2050 chip. It is a Class D power amp that will take any DC voltage between 12v and 30v. The power supply is made by Meanwell and is 27V 13A.
Currently it is wired for both stereo and mono. Basically, if you plug just into the left input, the inputs are bridged and you get 200 watts of mono operation. If you plug in both, you get 100 watts per side of stereo.
This is my prototype box so I did not go to the extra effort of soldering up all the connections. For any production boxes, all connections will be soldered for maximum reliability.
Simple Tolex covereing, red piping, metal grille, black handle, nickel corners and 4 rubber feet round out the package. The pics do not show it, but on the inside, there will be sound dampening material to eliminate any standing waves.
Sound-wise: I LOVE IT! My cousin currently has it out for its maiden voyage. He is doing a theater gig (West Side Story I think...can't recall exactly) this weekend and he said it sounded great with his Ultra! Once I get it back next week I'll be AB'ing it against my Mackie HR824's. We'll see see how it really stacks up then.
Thanks all for looking and any comments or suggestions are welcome!
