cabinet design help for 5 1/4" subwoofer

[gychang]

I like to design a small subwoofer using the Tang Band W5-1138SM,

pictured here: http://www.partsexpress.com/pe/showd...number=264-831

I will be using it mainly for listening to music, classical, jazz etc. I am very interested in mating it with my Cyburg Needles here:
New needles!: Homedepot mistake

I like to have a stylish subwoofer (if possible) and details of cabinet if someone can help, thanks,

if size is not a major issue. DJK discribes such a sub for a five inch unit well toward the end of the thread about 18 pages in.

"Ok, I can't hold it in anymore. I want to build one of these things. I have an orphaned (not one of a pair) RadioShack/Optimus 4" driver that has a Fs of 85 Hz, a Qts of 0.62, and a Vas of 0.10 ft^3. It has a decent mechanical excursion limit, and a nice big magnet. Would it be suitable for a waveguide system like the one pictured in Post #7? "

Post #7 just shows a 1/4W trans line. The Sound Cannon would have about 6dB more output and less cone motion, very important where small drivers are used.

For a computer desk system it is quite easy. Use a 20" long by 3" dia pvc pipe in front of the cone. Make a little box for the drver and pipes to fit into. The box hold the driver and acts like a 90* elbow. The box would be at the back left (or right) corner of the desk. A second pipe 40" long goes across the back of the desk into a 90* elbow, and then to the front through another 20" pipe. The whole thing can be hung to the underside of the desktop with a couple of strap hangers, or you could hang it on the wall.

I was actually thinking of making a folded TL sub out of one of those so I could have a smaller sub since I'm moving into a condo. Anybody done the calculations on Martin's sheets for that one?

velmerand42,

Here is an example of a folded 27.3 L TL with the W5-1138SM.
Any larger dimensioning like CSA=2 x Sd and length will work even better as this TL has minimum CSA and length.
