Lubell VC2C Underwater Acoustic Transducer

Lubell Labs now has a woofer for sale. It is the VC2C and has been under development for several years. It adds a new dimension to underwater sound for bodies of water having 10' minimum depth. (The VC2C must be used at 10' depth to prevent damage.) It is literally sound that you can feel! Because of limited quantities, sales will be limited to marine scientists, ocean engineers, the military, and to laboratories in the United States. We recommend connecting the VC2C to the 4 ohm and common terminals of the Bogen Classic 100 (C100) amplifier only. Since the VC2C has a maximum current rating of 2.5A, we recommend installing an inline fuse holder with 2.5A fast-blow fuse in series with the white signal lead to help protect the VC2C against burn-out, especially considering that the Bogen Classic 100 is capable of producing 5A of current.
