DLS-mini ceiling-mounted 2.5-inch full-range speaker with an all-aluminum enclosure, designed for background music (BGM) and high-clarity conference sound reinforcement.
It uses an all-aluminum enclosure and aluminum cone woofer with a passive aluminum radiator, delivering a low-frequency extension down to 90Hz in a compact form factor. This solves the problems of cabinet resonance and poor bass response common in plastic small speakers.
With dimensions of only 109 x 73mm and a cutout diameter of 85mm, it weighs just 0.45kg. It is designed for ceiling or wall installations where space is limited, requiring no additional structural reinforcement.
The frequency response covers 90Hz to 20kHz, and with a 4-ohm impedance and 85dB sensitivity, it can be driven by standard amplifiers. This eliminates the need for a separate subwoofer typically required for small speakers to achieve low-end coverage.
