ZTZ Audio designed the TN-18P300 to play louder, and lower, than most every other speaker manufacturer's subwoofer in its price range. A thoroughly vented, well executed motor with an inside-outside 4" voice coil is utilized to minimize output-robbing power compression, while also increasing driver longevity and power handling. The use of a dual spider suspension, mated to a cotton M-Roll surround and attached with a special resin, allows for extreme linearity during intense use.
A reinforced cast aluminum frame increases rigidity and resists frame flex. Spring-loaded speaker terminals allow for easy speaker wire connection. This popular professional audio subwoofer is at home in bandpass or ported (bass reflex) speaker cabinets and has been used in live sound reinforcement, high SPL mobile audio systems, and as high output home theater systems.
