The Dayton Audio ND25TA-4 is a versatile 1” titanium-dome tweeter that offers the performance of more expensive tweeters in a compact and stylish package. It features a Dayton Audio exclusive round faceplate design with integral perforated steel grille, and a small yet powerful neodymium motor with attached aluminum heatsink and ferrofluid-filled magnetic gap for reduced power compression and improved long-term power handling. The carefully-designed titanium diaphragm provides clean, crisp treble response to beyond 22kHz, and delivers superb sonic detail and dynamics with low distortion. A copper pole cap further reduces distortion and inductance effects.
Choose the ND25TA-4 when you need maximum dynamic impact and powerfully-rendered sonic detail to keep up with a high-output midrange or woofer. The compact round faceplate design integrates easily into your baffle design without claiming a large amount of real estate, and the integrated grille protects the titanium dome from damage.
