The single ISO-200SUB Isolation Subwoofer Stand from IsoAcoustics prevents the transfer of speaker cabinet energy to surrounding surfaces, effectively isolating the speaker. By allowing the speaker to perform in free space, it's able to sound the way it was intended.

The ISO-200SUB measures 7.8 x 10 x 3.5". It can be used as a single unit for most subwoofers, or combined with additional units for larger subs. It can accommodate subwoofers up to 60 lb.
For use with most subwoofers
