PRV Soft Dome Tweeter TW150SD-4 with Built-In Crossover 240 Watts PAIR / 4 Ohm

The New TW150SD-4 is here to change the silk dome tweeter market (also referred to as a soft dome) with a new design, featuring a large 32mm dome with a 1.1” voice coil able to handle 120 Watts, and offering remarkable clarity and exceptional response above 2Khz.

With an overall diameter of 2.37”, and requiring a cutout mounting hole of 1.93”, these 4 Ohm tweeters are a great drop-in upgrade to vehicles with standard 2” factory tweeters, or can even transform your sound system with very little modification, using an easy flush-mount screw-on ring.

*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.
