Quam Nichols Company 30C25Z45OT Speaker 3 Inch 45 Ohm

Product Description

The QUAM NICHOLS COMPANY 30C25Z45OT is a compact round speaker designed for in-ceiling and in-wall audio distribution applications. With a 3-inch outer diameter and a 45-ohm impedance rating, this speaker is built for low-power distributed audio systems where multiple units are wired in series or parallel across a single amplifier zone. The 2.35-ounce magnet assembly provides the magnetic force needed for reliable cone excursion in a small-footprint driver. This unit ships as a single speaker and is intended for professional installation in commercial or residential audio distribution systems.

The 30C25Z45OT is suited for in-ceiling and in-wall installations in commercial spaces, offices, retail environments, schools, and similar facilities where background audio or paging is required. The 45-ohm impedance makes it appropriate for multi-speaker distributed systems. It is typically installed by licensed low-voltage contractors, commercial AV integrators, or electricians experienced in distributed audio work.

Key Features

• 3-inch outer diameter fits standard small-aperture in-ceiling and in-wall cut-outs
• 45-ohm impedance suits multi-speaker series or parallel distributed audio runs
• 2.35-ounce magnet assembly for consistent driver performance in compact form factor
• Single-speaker unit — sold individually for flexible zone-by-zone installation

Compatibility

Designed as an OEM-style replacement or new-installation driver for in-ceiling and in-wall distributed audio systems requiring a 3-inch, 45-ohm speaker.

Installation Notes

Installation is typically performed by a licensed low-voltage contractor or AV integrator. Disconnect and de-energize the amplifier or audio distribution system before wiring or replacing any speaker. Verify that the total impedance load across the amplifier output meets the amplifier manufacturer's minimum impedance requirement before energizing. Follow applicable local electrical codes and NEC guidelines for low-voltage wiring in wall and ceiling cavities.
