DAS Audio ARCO-4-T Passive Install Loudspeaker
The DAS Audio ARCO-4-T is a passive install loudspeaker built around a 4-inch 4G low-frequency driver with the TWT-4 tweeter. It covers 72 Hz - 22 kHz, and it reaches 109 dB peak at one metre. Nominal coverage is 90 deg horizontal by 90 deg vertical.
It is a passive box, 8 ohms nominal, handling 50 W RMS, so plan amplifier and processing to suit. Signal comes in on Spring Terminals. A line transformer is fitted for constant-voltage systems, tapped 70 V at 2.5 W-5 W-7.5 W and 100 V at 5 W-10 W-15 W. The enclosure is built in High Impact ABS. Net weight is 1.6 kg (3.5 lb). DAS lists it in black and white; pick the finish above, as each carries its own order code.
