The Walsh “style” TLS-1 by Dale Harder


The TLS-1 designed by Dale Harder.

The TLS-1 by HHR Exotic Speakers is a vastly improved version of the original Ohm Walsh “F”. While the design of the TLS-1 is modeled after the old “F” series, it currently incorporates more than 61 design improvements that are the direct result of 35 years research and experience.

The New TLS-1 is intended for use in medium to large rooms from 200 to 400 square feet.
