Product Details

DJ speakers, instrument amplification, and huge home stereo speakers all need a powerful treble sound to match their big bass. The 1TM-4 bullet horn tweeter is the perfect solution on a budget to add the desired highs to these types of speakers.


The 1TM-4 features a ring-type aluminum diaphragm on a phenolic carrier, and a 1" voice coil for rugged performance. The horn faceplate is cast in aluminum to make it resistant to damage.
