Anleitung Zusammenfassung


This 'systems engineering' approach involved extensive research to meet design goals for specific Thiele-Small parameters that would offer the user a wide range of choice of low frequency response, efficiency and compact size. Successful completion of this development program has resulted in a family of bass reflex cabinets from the compact 1,5-cubic foot 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 laminar flow for all conditions; this assures proper operation even at maximum acoustic sound power levels. Construction of each enclosure utilizes high quality 7-ply birch-face plywood. Extensive internal bracing maximizes rigidity and strength. The mar resistant 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 frequency loudspeakers, offer the user a wide choice of performance criteria while assuring smooth frequency response and low distortion at all sound pressure levels.
