I have for sale my James EMB-1000 subwoofer in piano black finish with black anodoized passive cone and front plate. This sub uses a 10" driver that is mounted internally and coupled to a passive aluminum cone driver that you see on the outside. The unique design coupled with the internal 1000 watt amplifier allow this sub to sound very fast and musical with high output all in a very small compact package.
I used this in a two channel music setup and the sub has very few actual use hours on it. No blemishes I can find on the front plate or passive cone and functionally the sub is perfect. I have the double box and power chord.
I am the original owner and purchased from a local authorized dealer. It is about 5 years old.
