Dayton Audio NHP25Ti-4 1" Titanium Dome High Power Neodymium Tweeter 4 Ohm

The Dayton Audio compact NHP25Ti-4 1" titanium dome tweeter uses a high temperature neodymium motor, Ferrofluid cooling, and rear mounted heatsink for improved heat dissipation making this tweeter suitable for higher output systems and even professional line arrays. In addition, the flat response and high efficiency makes the NHP25Ti-4 an amazing value.

Dayton Audios versatile NHP25Ti-4 is a 1" titanium-dome tweeter that offers the performance of more expensive tweeters in a compact and stylish package. The small yet powerful high temperature neodymium motor with attached aluminum heatsink and Ferrofluid-filled magnetic gap reduces power compression and improves long-term power handling. In addition, the carefully designed titanium diaphragm provides accurate treble response to over 20 kHz, excellent off-axis dispersion, and superb sonic detail.

The NHP25Ti-4 includes a 2.5" cast aluminum faceplate, however Dayton Audio does offer an optional 4.09" (104 mm) and 4.33" (110 mm) faceplate allowing this tweeter to be used as a drop in replace for many common sized tweeters.
