Product Details

Dayton Audio ND25TA-4 1" Titanium Dome Neodymium Tweeter

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 22 kHz, 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 grill protects the titanium dome from damage.

Dayton Audio ND25TA-4 1" Titanium Dome Neodymium Tweeter

I'm building a car system around the Dayton Classic 6.5. I'm debating this tweeter against the ND25FN. I prefer a metal dome, but which will pair best? Passive x-over suggestions?

Asked by: Islandtime Adam
The woofer will start to roll off just before 4kHz which is just about the low end limit for either of these tweeters. Either option should work if you use a 4kHz crossover, unfortunately we do not have any pre-built crossovers that will work with 4 ohm tweeters.

The tweeters out of my PSB Image 2B's have died.  Back of tweeter says 101003 and TW1-2AN/P PSB says these are no longer available and says they are interchangable with the tweeters from the B25's - do you have anything that will work

For car usage, would you recommend mounting these on or off axis? Any other useful information regarding car usage would be greatly appreciated. Thanks, Bob

Asked by: Bobby739
These will be no different than most other car type tweeters. Generally off axis will be better to help with overall sound stage.
