No, this is not a belated April Fool's prank. Hsu research has stopped selling their award-winning TN series cylinder subwoofers. It would seem they are poor sellers compared to the powered box series, and have been discontinued in preparation for the "turbo" adapted new flagship, the VTF-3 Mk.2 H.O. (damn thats alot of letters). Thats a shame because I had wanted to get a pair of 1220's for my 2-cannel system.
