Generic / Unbranded ma-420 Ceiling Speaker 4 in 8 Ohm

Product Description

The GENERIC / UNBRANDED ma-420 is a 4-inch in-ceiling speaker designed for direct connection to standard amplifiers at an 8-ohm load. The compact driver delivers clear, balanced audio reproduction suited to background music playback and voice paging applications. Its low-profile white grille sits flush against the ceiling surface for a clean, professional finish. This speaker is intended for residential and light commercial audio installations where a discreet, fixed installation is required. Licensed audio and low-voltage installers are the typical end users, though the straightforward design also supports experienced integrators working on multi-room systems.

The ma-420 fits residential rooms, commercial lobbies, retail spaces, and office environments where background music or paging audio is needed. The 8-ohm impedance allows direct wiring to most consumer and light commercial amplifiers without an impedance-matching transformer, simplifying distributed audio runs. Its 4-inch form factor keeps the ceiling cutout small, making it practical for retrofit installations in finished spaces with limited above-ceiling depth.

Key Features

• 4-inch driver for compact ceiling cutout and smooth audio reproduction
• 8-ohm impedance for direct amplifier connection without a transformer
• White grille provides a low-profile, professional appearance

Compatibility

Designed as a standard 8-ohm in-ceiling speaker compatible with most residential and light commercial amplifiers and distributed audio systems that accept direct 8-ohm speaker loads.

Installation Notes

Installation is typically performed by a licensed low-voltage or audio systems technician. Power down the amplifier and any connected audio source equipment before making speaker connections. Follow NEC Article 725 guidelines for low-voltage wiring in finished wall and ceiling assemblies. Do not exceed the amplifier's rated per-channel output when wiring multiple speakers on a single channel without proper impedance calculation.
