CF404 Series
GENERAL PRODUCT DESCRIPTION
The Altec Lansing Professional CF404 series is a high fidelity,
high performance, premium full-range loudspeaker. The
CF404 family is a popular choice in airports & transportation
facilities, restaurants & clubs, boutiques and all ceiling
applications that require high fidelity music reproduction.
The moisture resistant 4 inch / 100 mm speaker features a
rust-resistant frame. To aid in the dispersion of higher
frequencies, the loudspeaker employs an acoustically
isolated dome. The optional 70 V / 100 V transformers (4 and
8 Watts) feature a low < 0.6 dB insertion loss.

ARCHITECTS & ENGINEERS SPECIFICATION
The loudspeaker shall be an Altec Lansing Professional CF404
series with a 4 inch (100 mm) full range moisture resistant speaker,
acoustically isolated dome and corrosion-resistant die-cast frame.
The speaker shall have a power rating of 32 W EIA / 128 W peak.
The frequency response shall be 130 to 14,000 Hz +/- 5 dB with a
sensitivity of 94 dB @ 1 W 1 m. All transformers shall have a low
< 0.6 dB insertion loss. The model numbers shall be Altec Lansing
Professional CF404-8A for 8 Ohms impedance, CF404-4T with a 4
Watt 70 V/100 V transformer, and a CF404-8T with an 8 Watt 70
V/100 V transformer.
ENCLOSURES AND BAFFLES
All measurements were made in a standard AES baffle for a
12 inch driver. The driver was housed in a 0.084 ft3(0.002 m3)
enclosure.
The CF404-series ceiling speakers use a unique die-cast speaker
frame. Prior to installation in a standard 4 inch (100 mm) back can
or enclosure, please make sure that the CF404 frame dimensions
are compatible.
Please note that larger volume enclosures will result in altered
low frequency performance.
SAFETY CONSIDERATION
1. Appropriate connectors with suitable ratings must be used
to make all installation connections.
2. All unused taps must be insulated with suitable insulation.
3. Transformers and speaker combinations must be supplied
by a suitable amplifier incorporating ungrounded outputs
only and reinforced insulation (as per IEC60065) from output
to mains.
ACCESSORIES
Altec Lansing recommends use of our torsion-mounted enclosure
and grille for the CF404. Since the CF404 uses a unique die-cast
speaker frame, we recommend you check the frame dimensions
for compatibility before installing in an industry-standard
enclosure & grille assembly.
