The Audac ATEO4D/W is a compact 4-inch two-way wall speaker in white, the 16 Ohm version of Audac's ATEO4, for background and foreground music and speech in bars, restaurants, hotels, shops, offices, classrooms and homes. It combines a 1-inch dome tweeter with a 4-inch mid/low woofer, handles 35 W continuous (AES), 70 W program and 140 W peak, and has 86 dB sensitivity. Frequency response is 100 Hz to 20 kHz (±3 dB), extending to 65 Hz at -10 dB, with wide 130-degree horizontal and vertical coverage. The 16 Ohm impedance lets installers run more speakers in parallel on a low-impedance amplifier channel than they could with 8 Ohm models. It is mounted with Audac's CleverMount system, which lets the speaker be angled up to 30 degrees left, right and down and clicks onto its bracket for a quick one-person install; wiring goes to a 6-pin terminal block. The ABS enclosure with a steel grille measures 136 x 244 x 153 mm, weighs 2.05 kg and is finished in RAL9003 white. An Allen key is included. Supplier minimum order is 2 units.
