By rigidly coupling a loudspeaker enclosure to a floor by means of a "spiking" system, it is possible to dramatically improve clarity, stereo imaging, and bass response. This is especially apparent with subwoofer systems. The DSS Series spikes are precision machined from solid brass and then plated with a satin nickel finish. Each cone spike weighs 86 grams and measures 1-1/4" diameter and 1-1/2" tall. The two-piece threaded tip design allows for precise level adjustment. Barbed inserts and threaded studs are included for mounting internally or externally in cabinets with walls up to 1" thick. Set includes four satin nickel cone spikes, four satin nickel floor discs, four barbed inserts, and four M6 threaded studs.
