Sound Enhancer was founded in 2002 by Harold Smith Jr in The Woodlands, Texas.  The company was founded to introduce Manifold Horn Technology to the combo amp market. Their main product - The Enhancer, was an amp stand that could redirect sound from the open back of the combo amp to the front. According to the company: "The Enhancer™ is a rear loaded horn cabinet for a removable speaker assembly, using the existing speaker already mounted in the combo amplifier. Redirecting the sound emanating from the backside of your open back combo amp, expanding volume and frequency response. It also lifts and tilts the otherwise small combo amp cabinet for better sound projection." It came in 5 different sizes to fit different amplifiers.
