Clamped power and SQL-12 at 20 Hz. Only one coil is clamped so double the power figures for total power to the driver.

SQL's are back in stock. We are completely moved into our new facility. Shipping is active. Ready to rock and roll. 👍

Still moving and unpacking, but getting very close. FedEx will be operational mid next week. S&L, DatsLA, and Clio are ready to measure drivers. Test bench is put together for excursion testing, etc.

Klippel results on our HST-18. The driver was shipped for testing a few weeks before we started moving and test results just came in a few minutes ago. 40 mm Xmax, linear and symmetric suspension, and a killer set of parameters. 🥳

HST-18's are not available yet but the CF cones and foam surrounds are the items we are still waiting for. We will keep you all informed about their availability.

Moving moving moving. You never realize how much stuff you have until you move. These are a few pictures taken today of our current progress. Steadily unpacking and organizing every day. 👍

Absolutely fantastic and beautiful sound quality meet/GTG at Ian's this weekend. Lots of great sounding cars at the meet. Weather was perfect. And both the Audi and the C7 delivered lots of demos all day Saturday. 👍
