Dayton Audio's versatile NHP25F-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 up to 20 kHz, excellent off-axis dispersion, and superb sonic detail.
The NHP25F-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.
