Product Details

Fountek NeoCD3.5H Horn Loaded Ribbon Tweeter

Fountek, an innovator in ribbon transducer technology, is the first to mate true ribbon technology with horn-loading for high efficiency and low distortion with their NeoCD3.5H . A reinforced sandwiched-aluminum ribbon diaphragm and strong neodymium motor structure are extremely responsive, and deliver musical detail with speed and accuracy, from 1,100 to 30,000 Hz, while the wide horizontal off-axis dispersion makes for a larger listening sweet spot.

A taller element is used in the NeoCD3.5H, which tames vertical off-axis dispersion. This helps to minimize ceiling and floor bounce reflections for world-class, pin-point precise imaging, while the focused output also reduces the amount of sound pressure level drop over distance. Recommended minimum crossover frequency: 2,500 Hz @ 18 dB/octave.

Fountek NeoCD3.5H Horn Loaded Ribbon Tweeter

I would like to build a separate boxes for the Fountek NeoCD3.5H ribbon tweeter but would need a crossover.  Would the Eminence PXB:3K5 keep the ribbons safe?  If not a good match, do you have something I could consider? Thanks! -mike

Asked by: msutliff
Yes that crossover will work well with this tweeter.

Could this pair well with a Dayton PA310? What is roughly the max SPL? 

Asked by: monoiz15
Yes this should work well with that woofer. Based on the power handling of the horn the maximum output will be 104-105 dB, but this power is considered with a full range signal so realistic output should be much higher.
