I've been searching for the ultimate light weight 15"speaker enclosure. I finally found it and can't believe Mike Arnopol's new 15" Bassic composite cab. This thing defies gravity! At only 22 pounds it produces a seriously heavey bottom end. It has a great mid range also and is a perfect stand alone cab. When coupled with other cabs it provides that low 15" growl that is missing with cabs having multiple 10" or 12" speakers. And did I say it is loud? As a believer in not killing my back lugging heavey amps I have tried many ultra-light speaker enclosures including Epifani and Markbass. They are all good but this new addition is worth checking out. This cab accurately produces the vintage sound I'm looking for with my Fenders but is flexible enough to get what I want from a fretless 5-string.
