Our outrigger (Spike Bar) sets are available in (5) different sizes to fit all standard speaker and subwoofer sizes.

Each set includes standard hardware to mount to your speaker. If your speakers already have inserts installed then simply replace the standard 1/4-20 installation bolts included with your order with bolts having the same thread size of your inserts. Most speaker already have inserts installed.

Speakers of non-rectangular shape may require a couple different size outriggers.
Ex: A pair of Kef 206 speakers would require one pair of SBN9 for the fronts and one pair of SBN7 for the rear.
