There is a loudspeaker with what amounts to a super-tweeter built in: the Eminent Technology LFT-8b. The ribbon tweeter in the LFT-8 is employed from 10kHz up, fed from a 1st-order filter set at that frequency. The LFT-8b retails for $2499/pr, not much more than the price of the Townshend tweeter alone. Just sayin'. ;-)
Below the tweeter is the LFT (Linear Field Transducer) driver, which reproduces 180Hz to 10k (!). The best kept secret and value in hi-fi loudspeakers.
