TW400Ti-Nd-4 v2 (PAIR)

PRV Audio’s TW400Ti-Nd-4 v2 super tweeter (also referred to as a bullet tweeter) is designed to add high output, high frequency response to any speaker system. The titanium diaphragm combines with the durable, yet lightweight, Kapton™ voice coil former for sensitivity levels of up to 106 dB from 4,500 to 20,000 Hz.

Not only does this driver look as good as it sounds, it is also able to take a ton of power! Up to 120 watts of power handling are on tap with a 12 dB/octave crossover at 6,000 Hz to keep up with the most demanding professional audio, high output home audio, and high SPL car audio systems. A capacitor is included for protection from damaging frequencies at high power. Mounting hardware included.

*Nominal power handling is defined as the maximum RMS power that the speaker can handle in a 2-hour test with a pink noise with 6dB of crest factor and a bandpass filter with 12db/oct tuned in its usable frequency range.
**Continuous Program Power (RMS) is the maximum power that the speaker can handle considering a regular musical program using our recommended filters, this power can be used to define the optimum amplifier power to avoid a clean signal without clipping or saturation.
***Max Peak Power is the maximum power operation for the speaker, this power is allowed just for a few fractions of a second, usually found just on the peaks of the music. Keeping this power for a little longer timer will damage the speaker.

These tweets are extremely loud and clear! I added a pair these with a pair of TW450Ti-Nd-4's and they're actually louder and they're all running on different channels on the same amplifier and PRV DSP 2.8X. The clarity is amazing and the sound is very smooth and I'm very satisfied with my purchase.
