Valcom 8" In-Ceiling 2-Pack

The Valcom S-422A-2 delivers a pair of 8-inch in-ceiling speakers designed for 25/70-volt distributed audio systems. Each unit integrates the baffle and back box into a single assembly finished in white. The package suits commercial paging, background music and announcement installations where a plenum-rated layout is required.

25/70-Volt System Constraints

These speakers operate on constant-voltage lines at 25 or 70 volts, so they must be wired in parallel with appropriate tap settings rather than connected directly to a low-impedance amplifier output. The integrated back box meets ASTM E84 and UL 181 with a three-hour burn rating, allowing placement in plenum-rated drop ceilings without additional fire-rated enclosures. Installers should verify that the amplifier’s total load stays within its rated power budget.

8-Ohm Nominal Impedance

The 8-ohm nominal impedance determines how each speaker draws power from the transformer taps on a 25/70-volt line. Buyers who need a different impedance to match existing zone wiring or amplifier tap selections should look elsewhere.

Questions about this item

How do the 8" drivers in this 2-pack differ from other Valcom ceiling models?

The S-422A-2 uses 8" drivers with a 70 Hz–17 kHz response and 8 Ohm impedance, while the S-522A-2 is a separate model number with its own specifications.

What bass output can I expect from the 70 Hz low-end in a typical drop-ceiling install?

The 70 Hz lower limit provides usable mid-bass for speech and background music; deeper bass requires a separate subwoofer.

Does the 25/70-volt transformer cap the maximum SPL or frequency range?

The transformer taps set power levels for distributed lines; they do not alter the 70 Hz–17 kHz driver response or the 8 Ohm nominal impedance.
