"produced an almost startling solidity"

From the sun drenched, earthquake riddled coast of California comes an exquisite rumble that will stir the soul. Since its inception in 1991, HSU Research has delivered a secret blend of high quality, high output, high value bass that simply “sounds good.”

The STF line is the result of hundreds of hours of development by Dr. Hsu and his team. All costs go to a powerful BASH amplifier, defeatable auto-on switch, defeatable/continuously adjustable 24 dB/Oct crossover, phase switch, gold plated binding posts and RCA jack, spiked feet, custom driver with extremely good cone control (low Q), 3 inch diameter flared port, quality black matte finish, and our traditional rounded corners.
