this technology came out in the early-mid 90's and wasn't a big hit. relative to 3 - 12" drivers is kind of confusing, but because it doesn't use a normal motor assembly like a regular speaker, it's supposed to be more efficient and move more air because of it's design. unless you hear it in a car, i'd be carefull of buying it and getting your hopes up high. i'd get some 10" or 12" JL 10 or 12W6 drivers and call it a day to be safe.

do let us know if you are able to demo it, and what kind of amp was driving it.

thx...
