Virginia Sports Hall of Fame & Museum Uses SLS Loudspeakers for Multi-Media Theater

SPRINGFIELD, Mo., April 13 - SLS International, Inc. (OTCBB: SITI) announced today that The Virginia Sports Hall of Fame and Museum has installed a new, state-of-the-art SLS loudspeaker system in its new 125-seat multi-media theater. The new 5.1 surround sound speakers will provide clear and superior sound quality throughout the museum's intro theater, which is scheduled to play a pre-recorded show every half hour.

Randy Vaughn, president of AE Systems (formerly Ambassador Enterprises) and president of NSCA, worked with a number of professionals on the design team, spearheading the audio design and installation. "We recommended the SLS HT1800 series because we knew it would give the complete theater experience. The sound detail is amazing, especially with the incredible bass and high end."

The HT1800 series consists of five HT28R speakers and two PSS12 subwoofers. The HT28R is a dual-woofer version of the HT8R and is recommended for use when high output is a requirement. The additional 8" woofer makes the HT28R well suited for commercial sound or larger home theatre installations. The PSS12 powered subwoofer provides a ground shaking bass, powered by a built-in 300-watt amplifier. The 12" subwoofer has a very smooth and flat response to well below 30 Hz. Complete with a selectable and defeatable crossover, low and high level inputs, and feed through connections, the PSS12 produces very warm and musical low frequencies.

"Since we were dealing with a large design team, there were many great ideas that we discussed in the boardroom," said Vaughan. "With all the top-of-the-line equipment that we were able to install, the multi-media theater can be used for other occasions such as fundraisers with movies and live events as a high definition theater."

Established in 1972, the Virginia Sports Hall of Fame and Museum has been proud to honor Virginia's contributions to the world of sports as the Commonwealth's official sports hall and museum. On April 22, 2005, the Hall will open its new 35,000 square-foot facility in Portsmouth, featuring an updated Hall of Honor, computer databases, a dynamic digital theater, Campus Champions exhibits focused on Virginia's colleges and universities, and the Game Time interactive hall with hands-on fun for the whole family. Besides the racing simulators, other interactive exhibits at the new Hall will feature baseball, football, basketball, soccer, health and fitness, and broadcasting.

"We are very excited to have our products selected for such a significant installation," says Jeff Lowry, director of marketing for SLS Loudspeakers. "Delivery of high quality surround sound audio for critical listening environments is of paramount interest to both audio professionals and audiophiles. The HT1800 system gives the discerning listener a new, higher level, surround sound experience offering the clarity and impact expected from SLS."
