Duelund 1" Precision Audio Tweeter

Duelund tweeter are made to the same no holds barred standards that you would expect from Duelund`s crossover components. Both the tweeter and the woofer are based on the Duelund principles of low resonance frequency and low Qts, with exceptionally smooth roll of curves in order to control all unwanted resonances across the entire frequency spectrum.
