1" SOFT DOME NEODYMIUM TWEETER

WITH 104mmØ WAVEGUIDE

Dayton Audio has added a waveguide faceplate to the popular ND25 soft dome to create the ND25FW-4 tweeter. The waveguide faceplate controls dispersion to minimise ceiling and wall reflections, which in turn leads to an increase in efficiency across most of the passband.

The Dayton Audio ND25FW-4 tweeter features a unique integrated round waveguide faceplate that provides a controlled directivity transition at high frequencies, reducing the effect of room reflections on the speaker's tonal balance. Unlike conventional flat-faceplate dome tweeters whose directivity does not match the midwoofer driver near the crossover frequency, the ND25FW-4's waveguide is curved to maintain consistent directivity at the transition. The waveguide also acts as a low-compression horn, lowering distortion.
Waveguide-loaded dome tweeters are embraced within the industry for providing directivity control and mild horn loading without the negative effects of compression loading such as impulse smear and throat distortion where high levels are not needed. The waveguide
