SLS International Launches $1.5 Million Branding Campaign in Anticipation of Big Box Retailer Launch

SPRINGFIELD, Mo., April 7, 2005 - SLS International (OTCBB: SITI) announced today that it has begun a comprehensive $1.5 million national branding campaign in anticipation of the sale of its products beginning September 1st in a Fortune 50 retailer. The Company is also commencing its campaign in the expectation that it will shortly enter into agreements with other national electronics retailers.

The Company will focus its marketing efforts surrounding its new Q Line Silver Surround Sound Home Theater System. To support sales, the Company has placed SLS International banners in many minor league hockey arenas which are located near retail stores that will carry the Company's products.

"We are gearing up for the launch of our products in Big Box Retailers as a key element in making SLS International a household name," said John Gott, SLS International's CEO. "We believe, by targeting those individuals who participate in and attend sporting events that we will attract an important consumer. These activities, while reaching a broad consumer base, represent just one-third of our advertising budget. During the summer months, we plan on increasing our activities to build momentum as September approaches. We are very excited about the potential to deliver our unique ribbon-driver technology in a cost effective manner to as broad an audience as possible."

SLS also placed prominent banners at many of the National and American League baseball spring training facilities that will now host minor league baseball games. 37,000 SLS Logo banners have also been produced and are being sent out to Youth Soccer Leagues across the U.S. and over 4 million soccer team shirts will also feature the SLS logo. This exposure will put the SLS brand name in front of an estimated 20 million people on a regular basis.

The Company is also employing mobile billboard trucks at prominent sporting events such as the Super Bowl, Daytona Speed Week and the Final Four College Basketball tournament, where there was also a St. Louis City Bus that has been wrapped with the SLS Logo and other graphics promoting the upcoming launch. This Bus, along with others in several other cities, will be used beginning this Summer to build momentum ahead of the launch. As presently contracted SLS will also have backlit signage throughout the exercise and lounge areas at 350 Bally's Fitness Centers.
