On-StageSubwoofer Adapter
Independent shopping perspective
The Korena take
The On-Stage SSA21 is a steel subwoofer adapter built around a removable M20 section. Its upper adapter accepts male M20, while its tapered lower section works with 1 3/8-inch cups. That combination covers shallow and recessed M20 arrangements as well as 1 3/8-inch cup configurations. With a 100 lb. weight capacity and an included Allen key for M20 lug removal, it gives PA setups a practical way to address different subwoofer connection formats.
Strong match
Who this is for
- Connecting a male M20 speaker shaft to a subwoofer using an M20 or 1 3/8-inch cup arrangement
