DLS-mini full-range ceiling speaker
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.
Key Features
- All-aluminum enclosure effectively suppresses cabinet resonance for pure, natural sound
- 2.5-inch aluminum cone full-range driver optimized for clear vocal reproduction in conferences
- Aluminum passive radiator extends low-frequency response down to 90Hz
- Frequency response from 90Hz to 20kHz, balancing background music and speech reinforcement
- 85dB sensitivity, 4Ω impedance, 15W power handling for easy integration with various amplifiers
- Standard 85mm cutout diameter and lightweight design (0.45kg net) for quick ceiling installation
- Purpose-built for in-ceiling mounting, providing even coverage for BGM and meeting room applications
All-aluminum enclosure, 2.5-inch driver
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.
- The cabinet and diaphragm are both made of aluminum alloy, effectively suppressing resonance.
- 2.5-inch full-range driver ensures clarity for both vocals and instruments.
- Built-in aluminum radiator enhances low-frequency efficiency.
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 opening diameter is only 85mm, compatible with standard mounting brackets;
- With a lightweight design of 0.45kg, it reduces the load-bearing requirements of the installation structure;
- The overall depth of 73mm fits shallow ceiling spaces.
Wide Frequency Response
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.
- Frequency response extends down to 90Hz, eliminating the need for an additional subwoofer;
- 4Ω impedance allows for easy parallel connection of multiple units;
- 85dB sensitivity ensures compatibility with mainstream commercial amplifiers.
