Each loudspeaker in this line was engineered for a particular purpose. The 3154 is designed specifically for the reproduction of low frequencies with minimum distortion in a direct radiator enclosure. When used as an integral component of the 8154 Loudspeaker System (6-cubic foot vented enclosure), full capability of the 3154 is achieved. This system provides a 3 dB down frequency of 40 Hz with an optimum Thiele-Small alignment. Power capacity for the 3154 is 250 watts when measured by the new AES standard specifications. The 3154 will handle 500 watts of program material when configured as the 8154 system, or mounted in another suitable enclosure. As with all Altec professional series woofers, the 3154 is built with a structurally reinforced die-cast frame. The ferrite magnet structure coupled with an exceptionally high power voice coil provides low distortion even at very high sound pressure levels.
