Howdy TB. Need to downsize, so great gear has to go. This is a MAS 110S bass subwoofer. It has one 10" long-excursion speaker and Mike's infamous "vortexitude" cab design that has outstanding slam and dispersion. Must be heard to be believed. Works great with any cab to add serious heft and booty. You can get more info here: http://www.masoundworks.com/manage.numo?pid=15&module=shopping_cart&component=catalog&cid=4 This cab is rated at 8 ohms and has 2 speakon inputs. One of them is special - it has a passive crossover built-in to daisy-chain another speaker - this sends the low frequencies to the sub and the higher frequencies (say from 300 hz up, not certain) to the other speaker, which frees the other speaker up to push more power to the higher frequencies. Nice! Cab weighs approximately 30 pounds and is in excellent overall condition. Has feet to stand either vertically or horizontally. These are $825 new, plus shipping. $400 shipped CONUS (add $10 for east of Mississippi). Sorry, not interested in any trades. Thanks for looking.
