RI-K28 Rubber Feet maximize ButtKicker-brand system performance and are critical with any type of installation.

As energy from a ButtKicker-brand low frequency audio transducer travels through couch or chair, these rubber feet act like springs, allowing the furniture to move freely and independently of other structures.

The result is a much stronger effect without raising the volume/intensity level of the power amplifer. Along with this increased efficiency, users experience much greater tonal sensitivity and fidelity.
