Ceiling Speaker HQM HQM-SO1625 20W 100V White - in-ceiling audio speaker

HQM HQM-SO1625 is a 20W 100V ceiling speaker finished in white and designed for in-ceiling installation. The speaker provides line-level 100V public-address and background-music audio distribution at a fixed 20W tap. Its low-profile round grille and compact mounting depth make it suitable for flush mounting in offices, shops, corridors, meeting rooms and other commercial or residential interiors where unobtrusive, even sound coverage is required.

Advantages

The HQM-SO1625 offers a fixed 20W power tap on a 100V line, ensuring simple integration into distributed audio systems without the need for step-down transformers at each point. The white finish and slim bezel support discreet in-ceiling installation while the speaker’s construction is oriented toward stable, reliable background-music and paging performance. Installation is simplified by common cutout dimensions and mounting clamps suitable for typical false ceilings.

Suitable for

• Public-address and paging systems in offices, retail stores and schools
• Background music distribution in shops, restaurants and hotel corridors
• Corridors, meeting rooms and small conference spaces requiring flush-mounted speakers
• Residential spaces where integrated ceiling audio is preferred

When it may not be suitable

This fixed 20W 100V ceiling speaker is not intended for high-fidelity stereo listening or for applications requiring variable power taps per speaker. It is optimized for distributed 100V systems and background audio; therefore it may not meet requirements where low-frequency extension, high SPL for live music, or precise hi‑fi reproduction are primary goals.

Key specifications

• Nominal power: 20 W (fixed tap on 100 V line)
• Impedance: designed for 100 V line operation
• Form factor: round in-ceiling speaker with grille
• Finish: white bezel and grille for unobtrusive appearance
• Application: public-address and background-music distribution

How to use

Mount the HQM-SO1625 into a compatible ceiling cutout and secure it with the built-in mounting clamps or screws as appropriate for the ceiling type. Connect the speaker to the 100V line of the amplifier or distribution transformer using the speaker terminals. Verify that the speaker is set to the fixed 20W tap and confirm system impedance and total line wattage before powering the amplifier. After installation, play a range of test tones or music at moderate levels to confirm even coverage and adjust amplifier output for desired background level.

What to consider before purchase

• Compatibility with existing 100V line amplifier or transformer and total line wattage
• Ceiling thickness and cutout dimensions to ensure proper mounting and clearance
• Intended use: background music and paging rather than high-fidelity stereo
• Number of speakers required to achieve even coverage in the target area

Usage recommendations

For reliable performance, install HQM-SO1625 speakers spaced to provide even coverage and set amplifier levels to provide comfortable background sound rather than high-volume listening. Regularly inspect terminal connections and grilles for dust and secure mounting; replace or service any speaker that shows noticeable degradation in sound or physical condition.
