Overview

Peerless by Tymphany TC7FD04-04 2-1/2" Full-Range Line Array Driver 4 Ohm

Tymphany's TC7FD04-04 full-range driver features a compact 2-3/4" frame, 20 watt power handling, and 86.8 dB sensitivity. The TC7FD04-04 is ideal for any compact high output speaker such as sound bars, MP3 and cell phone docks, or even professional line arrays.

With Tymphany's patented PentaCut NRSC cone, a powerful ferrite motor, and copper capped pole piece, this driver has a wide frequency response of 200 to 10,000 Hz, with impressive off-axis characteristics. The voice coil is vented extensively, which increases power handling while reducing compression.
