Speaker Outriggers

NSMT Custom Loudspeaker Outrigger Kits: Fits speakers from 3.5 inches to 14 inches wide.

Stabilize your tower loudspeakers with our custom CNC aluminum outriggers machined from quarter inch thick aluminum and powder coated black.

Our outrigger and spike kits dramatically improve performance by rigidly coupling loudspeakers enclosure to floors to improve clarity and stereo imaging and to tighten bass response. They are especially effective on uneven floors and floors with thick carpeting.

(Note: The picture above shows outriggers outfitted with the deluxe isolation cones. Our outrigger kits are shipped with standard spikes or deluxe isolation cones that are shown below)
