BUILT-IN 3-CHANNEL AMPLIFIER
The 15” subwoofer enclosure is divided into two separate compartments. The front chamber serves as the cabinet for the 15” subwoofer. The rear chamber houses all of the system’s electronic circuitry, which includes the amplification for all three components, power supply and preamps. The 15” subwoofer has a power handling capability of 400 watts and a nominal impedance of 8 ohms.
10" TWO-WAY SPEAKERS
The two 10” two-way speakers are loaded with B-52’s custom 10” speakers and a 3/4” titanium diaphragm compression driver, mounted to a 900 x 400 constant directivity horn. The speakers are designed to be pole mounted, can sit as stage monitors and have built-in (3/8” – 16 TPI) flying hardware for permanent installations. The front panel of both two-way speakers is concaved so as to fit perfectly onto the subwoofers front grille for easy transport. Each two-way speaker has the power handling capability of 150 watts and a nominal impedance of 4 ohms.

LX-18	LX-18 - 18" Folded Horn Subwoofer The LX-18 takes traditional folded horn subwoofers to the next level. The cabinet is built to withstand the abuse of the road and is backed by a LIFETIME construction warranty. A newly designed internal compression chamber provides intense, clean and controlled bass. At the heart of the LX-18 is the new B-52 18-200L subwoofer with a cast-aluminum frame, a massive 200oz magnet and an innovative 4” dual-layer tempered aluminum voice coil.  B-52 folded-horn subwoofers provide the advantage of low-frequency horn loading from powerful and cost-effective cabinets, which are suitable for a wide variety of high-output applications. LX-Series enclosures provide high-efficiency, low distortion, increased headroom and a superior transient response. The LX-Series subwoofer will outperform any conventional direct radiating system by 3-6 dB at distances of 75-150 feet. That’s up to twice the SPL at these distances! These subwoofers will add earth-shaking, chest thumping bass to any system, so we highly recommend reinforcing your dance floor or stage before use!
