Billy Graham Training Center Cove Chapel Utilizes SLS International's Ribbon Technology

SPRINGFIELD, Mo., March 15, 2005 - SLS International (OTCBB: SITI) announced today that B & R Audio has selected and installed multiple SLS speakers as part of the audio system renovation at the 170-seat Billy Graham Training Center, The Cove's Chapel.

"The chapel is a very simplistic and beautiful room," says Bruce Jensen, audio engineer and owner of B & R Audio. "Part of the design included keeping the speakers completely out of sight. The units had to be something small with good pattern control, high-end and very flat response. We chose the SLS speakers because they have all this and more."

"We continue to win a substantial amount of business from churches and other religious organizations," said Jeff Lowry, SLS International's Direct of Marketing. "The flexibility provided by our speakers, along with the sound quality, makes them ideal for virtually any religious venue. We expect to penetrate further this large market."

The Cove's Chapel construction consists of hardwood floors, sheetrock and glass walls, and a sheetrock ceiling with a very high A-frame, so control was very critical. In addition to the chapel's acoustical challenges, Jensen also had to keep in mind that many of the musicians and presenters would be on the main platform in front of the speakers, which would cause significant feedback.

"The SLS speakers give us good coverage all the way to the back of the room, without bouncing off a significant portion of the back wall," commented Jensen. "We didn't use any acoustical treatments at all and the speakers still give off such a smooth, accurate sound. The detail of the SLS speakers is substantially better than any other traditional speaker."

After the installation was complete, the first group to use the new audio system was a children's choir that performed for a Billy Graham Training Center staff event.

"The SLS speakers performed wonderfully during our first event and continue to sound fantastic throughout each event," said Jarred Brackett, chief audio/lighting technician at the Billy Graham Training Center. "The room has such a tall ceiling, so the reverb time is fairly high, close to three seconds. The SLS speakers are great for this room because of their tight coverage patterns."
