I've got a pair of Sonosubs I'm thinking about letting go, but they would be most likely more then anyone would want to pay for a DIY sub unless they want a vary large and unique sub that will outperform nearly any commercial sub on the market for under 3K.
They have a Port Valve on the top that can be opened or closed for sealed or vented alignment (Music and Movies) and each has a modified Maelstrom 18” driver. They measure flat to 10Hz in my room and have output around 120db @ 20Hz.
Price would be, well a lot to even make it worth my consideration, they cost over 1K each to build and took over a year to construct for the pair. I would probably sell them for $1700 each, can’t imagine what shipping would be though.
I really don’t expect to sell these, and in reality I don’t want to, but I thought I would put a feeler out and see if there is any interest, I might really need the money in the near future and if someone local wants them or can afford to pay shipping and my asking price I would let one go, maybe both, but I doubt it.
