Brand NEW! Including 90 Days USA Factory Warranty. Sharing the same look as Dayton Audio's popular Designer Series drivers, the DSN25F-4 1" soft dome tweeter has been optimized to deliver smooth response with remarkably high efficiency. With a compact faceplate, low distortion copper cap, and 4 ohm impedance, this tweeter is ideal for use in 2-way MTM designs. Key Features Silk dome produces natural response with low distortion Exceptionally flat high frequency response for accurate and dynamic reproduction Copper cap lowers inductance and reduces distortion 1" diameter voice coil with ferrofluid cooling for excellent power handling High-strength neodymium motor offers low distortion and high efficiency Retains the same "family look" as the popular Designer Series woofers, subwoofers and passive radiators Dayton Audio's Designer Series DSN25F-4 1" silk dome tweeter has everything you have come to expect from the Designer Series drivers such as smooth frequency response, low distortion, good efficiency, and even a matching frame. Driver integration and crossover designs are simple with smooth response from 2,500 to 20,000 Hz and predictable roll off on the low end. The powerful Ferrofluid cooled neodymium motor provides high efficiency allowing excellent dynamics while keeping size and weight to a minimum. Finally, the DSN25F-4 includes a copper cap on the pole piece to lower distortion ensuring accurate high frequency response.
