The Altec Lansing 9864A is a two-way, factory assembled, vented bass Duplex® horn system. This compact system features high sensitivity, high output capability, point source alignment with excellent directivity control down to 200 Hz. The coverage at 500 Hz is 70° horizontal by 50° vertical and the systems nominal coverage is 60° horizontal by 40° vertical. The bass reflex porting extends the low frequency response to 50 Hz, or lower if multiple units are used. This unique driver utilizes the low frequency magnet structure to support both low and high frequency voice coil assemblies. This physical driver alignment creates a true point source device. The 9864A "Duplex" driver combines the Altec Lansing 515-8GHP 16 inch (40.6 cm) low frequency driver and 299 1.4 inch (3.6 cm) high frequency compression driver with a 60° by 40° constant directivity horn for smooth directivity through the crossover region. The system should be used with an electronic crossover, and the recommended cross- over frequency is 1 kHz. The 9607A plug-in equalization module can be used to provide equalization in Altec Lansing electronic crossovers. The enclosure will also accept the standard Altec Lansing passive crossover network. The enclosure is constructed from 3/4-inch (1.9 cm) thick, thoroughly braced 7-ply birch plywood lined with sound absorbent glass wool. Threaded insert mounting points are provided to conveniently attach the Altec Lansing 816VI-SK suspension kit. The system may be hung as a single unit or as part of a cluster. The enclosure is covered in a new and unique wood-grained vinyl which can be painted or stained to complement any interior. The enclosure is supplied with a removable black metal grille. The 9864A can be used individually or in arrays to create compact, high output and directivity controlled systems for use in churches, auditoriums, hotels and civic centers.

NOTES ON MEASUREMENT CONDITIONS 1. Pink noise signal, one Watt calculated using E2/Zmin, 3.16 meter-measurement distance referred to one meter. 2. On-axis, one Watt calculated using E2/Zmin, 3.16 meter-measurement distance referred to one meter, low frequencies corrected for anechoic chamber error. 3. This system rating patterned after the AES method for individual driver, where the test signal is pink noise with a 6 dB crest factor over the bandwidth of the system, with power calculated using the E2/Zmin, for two hours. 4. This measurement made under the same conditions as Pressure Sensitivity, but at rated power, and takes into account any power compression effects due to non-linearities in the system. 5. Distortion components invalid above 10 kHz. The distortion at any given frequency may be found by graphically taking the difference between the fundamental and harmonic, and adding the number of Decibels which the harmonic has been raised on the graph and apply the formula: % distortion = 100 x lOl
