The simple, yet elegant looks of the MJ-18 makes it a desirable choice for home theatre and car subwoofer systems. The MJ-18 is used extensively by DIYers for infinite baffle configurations where bass reaches sub-harmonic levels. Its lightweight craft pulp cone and thick foam surround allows for tight, punchy bass, while the 8 pound magnet structure ensures control of the driver through a 3" voice coil. Its a serious sub, for serious people.
