8000 SERIES
LOUDSPEAKER SYSTEMS
The Altec Lansing 8000 Series Loudspeaker Sys tems are a new family of vented cabinets for the new 3000 Series professional low frequency loudspeakers.
The 8000 series cabinets and the 3000 series loudspeakers were designed as integral systems to obtain varied performance characteristics. This 'systems engineering' approach involved extensive research to meet design goals for specific Thiele­Small parameters that would offer the user a wide range of choice of low frequency response, effi ciency and compact size.
Successful completion of this development pro gram has resulted in a family of bass reflex cabinets from the compact 1.5-cubicfoot Model 8127, to the 24-cubic foot Model 8182, which is used for
extended low frequency response. Careful vent design provides sufficient cross-sectional area to achieve laminarfiowforall conditions; thisassures proper operation even at maximum acoustic sound power levels.
Construction of each enclosure utilizes high quality 7-ply birch-face plywood. Extensive internal brac ing maximizes rigidity and strength. The mar resist ant textured gray spatter finish assures high durability.
All in all, the eight enclosures of the 8000 Series family, in conjunction with the 3000 Series low fre quency loudspeakers, offer the user a wide choice of performance criteria while assuring smooth fre quency response and low distortion at all sound pressure levels.

' Dual loudspeaker system. Sensitivity and maximum SPL includes 3 dB gain due to loudspeaker coupling. ^ Measured with 1 watt (E x I) input of band-limited pink noise from 100 Hz to 1 kHz at 1 meter. ^ 7-ply birch face plywood. Acoustically braced on all sides, except for small 1.5-cubic foot unit.
Incident sides lined with fiberglass except for Model 8182. Mar (scuff) resistant textured gray spatter for high durability.
The response and impedance of each system are published with the specifications for the 3000-series loudspeaker used
in the system.
