Sorry, This product is no longer available



A SuperTweeter is a small high frequency drive unit, mounted in a special casing, designed to sit on top of, and drawing its input signal from, existing speakers. This will transform any sound system, creating the effect of a quantum leap upgrade in the sound quality of speakers, electronic components and cables. All models are stand-alone units with vertical axis adjustment to ensure optimum combined acoustic output with the main speaker. Each has two sets of controls allowing both operating frequency and output level to be optimised for any type of speaker. ST100 SuperTweeter come in solid black ash and with the same Performance Platform as the ST200. This model is provided with specific crossover and frequency control settings suited to all types of speakers, regardless of manufacturer. In addition the ST100 is optimised for use with older Tannoy Dual Concentric models, many going back over 40 years to the original 15" Monitor Red derivatives.
