IsoAcoustics V120 107x50 Adapter – a steel mounting plate that links a speaker with a 107.9 x 50.8mm hole pattern to the V120's L-Bracket or C-Bracket.
The pattern is the same as the 50x107 Adapter, just rotated 90 degrees – for monitors where the manufacturer laid out the mounting holes horizontally instead of vertically. Without a matching adapter plate, mounting speakers such as certain Focal, Genelec, or JBL models to the V120 would mean drilling into the cabinet, a fix most engineers want to avoid on gear still under warranty.
Matching a horizontal hole pattern
The 107x50 Adapter has a 4¼" x 2" (107.9 x 50.8mm) hole pattern matched to the rear mounting of the brands above, and bolts directly to the speaker cabinet using the included M6 and ¼"-20 fasteners. The distinction between the 107x50 and 50x107 patterns matters in practice – ordering the wrong orientation means the plate physically won't line up with the cabinet, so it's worth confirming the hole layout before mounting.One V120 system, multiple monitor brands
Since the adapter simply bolts onto the existing L-Bracket or C-Bracket, the install keeps the V120's full isolation function – damping structural vibration and adjusting tilt up to 45° – unchanged. In a room with monitors from different brands, an engineer can run one V120 mounting system and swap in the matching adapter plate for each speaker model.KEY FEATURES
