Motorola Contracom Speaker enclosure with built in 8 Watt audio amp. High quality volume control. These speakers are pull outs from DE-commissioned Radio dispatch systems. They provided a small independent amplified speaker for each radio channel. They have a RG-45 connector on the back that brings in DC power, the low level audio feed, and \"Turn on\" logic. The amp chip is very durable and of high quality. I have a bunch of these. Useful anywhere you need a small amplified speaker. There is enough room inside that you could put in a 9V dc battery and make it portable. The Motorola part number is BSN6003A51. Here is a link to the audio amp device inside the unit... Plenty of room for other circuit boards as well. Free shipping to the lower 48 states. Payment by pay-pal within 3 days of sale close. US Sales only.
