This listing is for a  Pair of Altec 9846B BiAmplified Studio Monitor Speaker Systems 9846-8A Powered by 771B. The 9846 Studio Monitor Speakers came in 2 versions the 9846-8A and the 9846B. the design of the cabinets and the low frequency and high frequency components in both version were the same. The basic difference was that the 9846-8A had a passive Altec N501-8A crossover with a 30923 attenuator and the 9846B employed the Altec 771B solid state bi-amplifier/crossover with a 60/30 watt (60 watts for bass and 30 watts for treble) combination and both versions were rated at 8 ohms. So the 9846-8A needed amplification and the 9846B could be used with amplification or be self powered.  When the speaker cabinets were produced at the factory they came with cutout so that a 9846-8A could be converted to a 9846B and that is what must have happened to one of the speakers as it has the 9846-8A factory label but has the 771B amplifier/crossover installed, the other speaker has the 9846B factory label. The speakers are in good working condition and can be used with or without the solid state power bi-amplification that is built in, the sound of the speakers is quite dynamic. .

The speakers sound quite nice and the component complement of each speaker consist of  411-8A 15" woofer, 802-8D driver with 511B horn a 771B Amplifier/Crossover. The frequency response of the 9846B speakers is 30Hz to 20KHz. The cosmetic condition of the speakers is very good and can be seen in the pictures. The woofer surrounds were re-done professionally and the speakers are ready many more years of audio reproduction. One of the dust caps was pushed in prior to my purchasing but it does not affect the sound.

*******Please accept my apology about some of the poor pictures. For some reason there were flash spots that look like round light greyish different size spots on the speakers but they are present on speakers when you compare the pictures*********

Due to age the speakers are Being Sold AS IS.
