Tang Band Dual 5"

There is a replacement for displacement. Larger air volume and ports that do the work. This enclosure works similar to how one can excite the air in an empty bottle. Huge sound, excellent low end bass and notes that sound like the actual instrument.

Enclosure Assembly

Built using .75" particle board. I am not a huge fan of MDF because of the tedious work of pre-drilling and applying the proper torque on the screws, countersinking, etc. Most people will whine about this, however the amount and placement of the ports provide more than adequate bracing and sonic deadness of the enclosure. Strong enough to support me, 185lbs, standing and jumping on the box. Could hold an elephant. 1-5/8 screws attaching all with clear silicon at all connections and seams. 1/2" round over on the ports. Finished with automotive carpet.


Tested against 2-10" Kenwood Excelon subwoofers in a sealed enclosure and 1- circa 1998 JL Audio 15W3-D2 (real American made JL) vented Prowedge enclosure. This box on equal power was substantially louder and had more fidelity than the Kenwood woofers and was at the least even money with the JL on almost all program material except for sub 40Hz material.

About The Designer

I try to more with less. I have a passion for trying to extract large and mind-blowing output from small drivers. I am a firm believer that the enclosure is 90% and the driver is 10%. And most of my designs prove it, if you want to trade air volume for it.
