Choose between 8, 10, 12, 14 or 16 kHz to set the Super Tweeter floor for the perfect blend with your speaker. The OFF position renders the Super Tweeter inert. The lowest setting, 8 kHz, will provide the most overlap with your existing tweeter while the highest setting, 16 kHz, will have minimal overlap, picking up at the top-end of the range. Use the treble adjust to reduce the output of the Super Tweeter. Just flip the switch and adjust to taste, up to -5 dB. The Super Tweeter shares the same binding posts as the speaker you're pairing it with. It feeds off the power your main speaker is already receiving, so no need to connect directly to an amplifier.
