Description
The RF41-20 is a 4”, full-range, blind-mount, in-
ceiling speaker which delivers true high-efciency
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 retrot 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 retrot applications.
• Reduced amplication costs and maximum
efciency with 88.5 dB sensitivity and 8 Ω
impedance.
• Superior voice intelligibility with an average
coverage angle of 110° (2-10 kHz,
independently veried).
• Fits standard 8” back cans for retrots.
