The Walsh “style” TLS-4 by Dale Harder
The TLS-1 designed by Dale Harder.The ultra new TLS-4 is a Walsh “style” tweeter/mid-range module. While it is also based on the Lincoln Walsh principal, it is an entirely new product with many exciting features. The TLS-4 was created to bring “Walsh awareness” to the masses and it is an affordable alternative to the larger sibling TLS-1 and 2 models.
We are currently offering the TLS-4 to the DIY speaker enthusiast market.
