Description

The RF41-20 is a 4”, full-range, blind-mount, in-

ceiling speaker which delivers true high-efciency

and performance across the operating bandwidth.

The full-range driver design delivers maximum

frequency response (71 Hz - 22 kHz, ±10 dB) in a

compact design. Mounting hardware is included and

features fast and easy retrot connections. For easy

ordering, stocking, and installation, the RF41-20

includes a ve-position tap switch for 25, 70.7, and

100 V applications with a transformer bypass position.

Grilles are optional and come in white only.

Features

• One full-range 4” (102 mm) treated ber woofer

with cloth surround.

• Easy-access ve-position tap switch for

25/70.7/100 V and transformer bypass position

plus spring terminals allow for rapid ordering,

stocking, and installation.

• Engineered for installation with limited plenum

space or retrot applications.

• Reduced amplication costs and maximum

efciency with 88.5 dB sensitivity and 8 Ω

impedance.

• Superior voice intelligibility with an average

coverage angle of 110° (2-10 kHz,

independently veried).

• Fits standard 8” back cans for retrots.

• High-quality white paint nish grille.

• Optional accessories: white metal grille (AC-GRL-

RF41) sold only in packs of 4.
