Iso/Isolation Cab/Cabinet D.I.Y. build Like Rivera Silent Sister

Isolation cabinet I built for electric guitar recording. Modeled loosely after the Rivera silent sister. One thing I didn't like about the Rivera aside from the price was the flip open door. I made a top half of the cabinet that could be completely taken off so that I could easily change the speaker. 4 screws and the speaker can be lifted out an a different one put in. I also used threaded aquarium bulk heads on the sound vent/ ports so that threaded covers could be use to close up any or all of the 4 ports. http://www.amazon.com/gp/product/B000... http://www.amazon.com/gp/product/B006... http://www.amazon.com/gp/product/B000... http://www.amazon.com/gp/product/B000... http://www.amazon.com/gp/product/B003... http://www.amazon.com/gp/product/B009... http://www.amazon.com/gp/product/B009... http://www.reliablehardware.com/large... http://www.tubesandmore.com/products/...
