SRS Labs Joins Russell 2000(R) Index

SANTA ANA, Calif., June 30 /PRNewswire-FirstCall/ -- SRS Labs, Inc. (Nasdaq:
SRSL), the industry leader in surround sound, audio and voice technologies,
was added to the U.S. small-cap Russell 2000(R) Index after the equity markets
closed on June 26, 2009. Membership in the Russell 2000, which remains in
place for one year, is based on membership in the broad-market Russell 3000(R)
Index.

Annual reconstitution of Russell's U.S. indexes captures the 4,000 largest
U.S. stocks ranked by total market capitalization as of the end of May.
Russell determines membership for its equity indexes primarily by objective
market-capitalization rankings and style attributes.

The Russell 2000 Index measures the performance of the small-cap segment of
the U.S. equity universe. The Russell 2000 Index is a subset of the Russell
3000 Index representing approximately 10% of the total market capitalization
of that index. The Russell 2000 is constructed to provide a comprehensive and
unbiased small-cap barometer and is completely reconstituted annually to
ensure larger stocks do not distort the performance and characteristics of the
true small-cap opportunity set.

"The addition of SRS Labs to the Russell 2000 Index represents another
milestone for our company," said Thomas C.K. Yuen, SRS Lab's chairman and CEO.
"Our inclusion in the Russell 2000 expands awareness among institutional
investors and the investment community of our accomplishments, as well as our
strong potential for growth this year. We believe this listing is another
indication that our investment in sales, marketing and engineering
infrastructure over the last year is beginning to pay off in terms of
increased revenue and major design wins."

Russell indexes are widely used by investment managers and institutional
investors for index funds and as benchmarks for both passive and active
investment strategies. An industry-leading $4.4 trillion in assets currently
are benchmarked to them. These investment tools originated from Russell's
multi-manager investment business in the early 1980's when the company saw the
need for a more objective, market-driven set of benchmarks in order to
evaluate outside investment managers.
