Description

The QI45EW is a small wall-mounted two-way speaker designed for both indoor and outdoor installation. It uses a UV-resistant ABS enclosure with an aluminium grille, so it can stay in place through varying weather. A 4.5" polypropylene woofer and a 0.5" PEI dome tweeter share a crossover network inside a bass reflex cabinet.

It is rated for 10 W to 50 W of power handling with an 8 ohm nominal impedance and 86 dB/1W sensitivity. Frequency response runs from 85 Hz to 20 kHz, which suits background and foreground music rather than deep bass reproduction.

The speaker mounts with an included versatile bracket with 70 mm hole spacing. With the bracket fitted it measures 135 x 245 x 170 mm. Typical uses include outdoor dining areas, restaurants, indoor public spaces and conference facilities. It is offered in black and white finishes and carries a five-year warranty.
