Originally developed for the Rockport Technologies Arrakis loudspeaker, the Ultra 7 V2 is the culmination of Stillpoints' work on high-mass loudspeaker isolation. Its multi-pocket construction is designed to lower mechanically induced noise while improving resolution, bass control and three-dimensional image depth. Application-specific thread sizes allow direct installation on compatible loudspeakers from Rockport, Avalon, Wilson, Raidho and other manufacturers; the final thread specification should be confirmed for the loudspeaker before ordering.
