The Tekton Design Proprietary Tweeter Array is a patented innovation (U.S. Patent 9247339) featuring a low-mass, polygon-oriented configuration of multiple tweeters, typically 7 in a circular or poly-cell arrangement. It acts as an ultra-lightweight midrange transducer, with outer tweeters handling upper midrange (e.g., below 3kHz) and a central tweeter managing higher frequencies, providing horn-like controlled directivity without ringing or comb filtering. Total moving mass is approximately 2 grams, enabling precise reproduction of harmonics like a 440Hz violin note. Used in models such as Perfect SET (triple-ring radiator), Double Impact (7 tweeters), Electron, Pendragon, and Enzo Reference. Drivers often Scan-Speak or SB Acoustics SB29RDNC-C000-4. Crossover progressively engages outer tweeters at lower frequencies for efficiency boost to ~93-96dB and narrowed directivity.
