SLS International's Newest Line Array Product Installed in NASCAR Facility

OZARK, Mo., May 24, 2006 -- SLS International (AMEX:SLS) , a leading provider of premium quality sound systems for professional (recording studio, concert, etc.), cinema and home entertainment markets, announced today that its newest Commercial Line Array Speaker Product, the LS6593, has been purchased and installed at Phoenix International Raceway (PIR), one of the many facilities owned by the NASCAR Founders International Speedway Corporation (ISC). The installation was completed in the new Bobby Allison addition and the response to the performance of the system has been overwhelming.

The SLS products were introduced and demonstrated to the President of the Grand American Road Racing association, Roger Edmondson at a Grand Am event in late 2005. He was so impressed with the ribbon-driver technology and the sound that shortly after he and the CEO of ISC, James France made a visit to the SLS factory to discuss using the SLS products for their facilities. As the decision was made to utilize the SLS products in an upcoming installation at PIR, SLS brought in their local contractor, Sound Image, with over 30 years in the audio industry, to work with SLS's field engineering team and prepare the design and ultimately complete the installation.

"I was incredibly impressed with the new SLS LS6593 Line Array Speakers," stated Marty Waverley, General Manager of Sound Image in Tempe, AZ. "Knowing this was new technology, as SLS had just released these new cabinets, and using them for this type of installation and application, I was a bit skeptical; however, my expectations were exceeded by the performance of the SLS technology. After we installed and checked SPL (Sound Pressure Levels) from anywhere in the grandstand, the readings were outstanding. SLS also exceeded expectations in customer dealer care and assistance from the initial contact with the client to the final test and balance of the system. The new system was used for the first time during a NASCAR Nextel Cup race the weekend of April 21st and from what I have been told by Lee Baumgarten, Director of facilities at PIR, this was the first time they were not bombarded with emails and phone calls about the audio, or lack there of, from a race day event! We look forward to working with SLS on many high-profile installations of this type in the future."

"The success of this installation is yet another validation of our technology and our capabilities to find solutions for any and all types of audio needs throughout the world," stated John Gott, Chairman and CEO of SLS International. "Due to its ability to focus sound directly to the listeners in such a manner that there is very little loss at great distances as compared to conventional speaker systems, our systems are being specified around the world in multiple different types of installations, including educational, religious, municipal as well as sports venues. We expect them to become utility tools that can be used by numerous sound designers in the future. Due to the outdoor rating on this new product, it opens up many new potential sales possibilities for SLS in sports arenas and concert facilities. With this acceptance by the originators of NASCAR we feel that our technology could become the benchmark for all outdoor racing and sports venues in the future."
