sa221s
Synergy 2x 21” Powered Subwoofer
This powerful dual 21-inch subwoofer offers the highest peak power and deepest bass response of any speaker in the Synergy series, Yorkville Sound’s largest and most powerful point source system.
The SA221S can be combined with an SA153 as an independent system, or with the SA153 and SA315S as a 5-way system.
If it were any more powerful, it would have to be measured on the Richter scale.
