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-resistantdie-castframe. 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 CF404-8Afor 8 Ohms impedance,CF404-4Twith a 4 Watt 70 V/100 V transformer, and aCF404-8Twith an 8 Watt 70 V/100 V transformer.

ENCLOSURES AND BAFFLES

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.

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-seriesceiling speakers use a uniquedie-castspeaker 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.

MOUNTING DIMENSIONS

ACCESSORIES

Altec Lansing recommends use of our torsion-mountedenclosure and grille for the CF404. Since the CF404 uses a uniquedie-castspeaker frame, we recommend you check the frame dimensions for compatibility before installing in anindustry-standardenclosure & grille assembly.
