Lot of two of them for a stereo setup! Requires some knowledge of electronics and soldering to use. These speakers were designed for use in the "universal translators" like the Phraselator issued to soldiers and police. I found they are best used in reverse as they make an excellent dynamic microphone for the human voice while ignoring the background bass and drums. Used as a speaker they can produce an amazing 90 decibels without any distortion in the range from 700hz to 4khz, but are usable at less volume from 150hz to 7khz. Coil impedance is 48 ohms. If that isn't enough they can take fairly serious immersion in water if the device they are installed in is properly sealed around the speaker. I replaced a mid grade Sure voice microphone with one of these and put it in an old mic case. The result was exceptional, preforming as good as two hundred dollar + vocal range microphone! This item is extremely hard to find. I have lots of lasers and other unique tech stuff for sale this week.
