 3000-1801-2 Complete Subwoofer System Includes: 

- 2 LS1801 18" 1000W Subwoofers

LS1801 18" 1000W Subwoofer: 

The LS1801 is very compact high Q subwoofer design to add extended low frequencies to any system. Effective for both permanent and portable applications, it comes with handles, rubber footpads, and a 1-3/8-inch pole mount cup. Covered in black DuraTuff™. 

Applications include:
- Small to Medium Club System
- Medium DJ system
- Small to Medium House of Worship
- Working Band PA 

The LS1801's compact design competes in size with most 18-inch subs, but because of the high Q 3-inch voice coil, 18-inch woofer with a power capacity of 500w/1000w/1500w peak, it out performs other 18-inch subs on the market. With its included pole mount, systems such as the LS1502 to the larger LS1503 can be elevated on its optional pole to become the optimum high power system. Even the low-end of LS1523 and LS2153 can be extended down to the 30 Hz range by placing the matching footprint of the LS1801 underneath. The enclosure is constructed of CNC machined multi-ply Hardwood with heavy gauge steel powder coated front grills. The crossover includes 4 pin NL4 Speakon and 1/4" phone connectors mounted on FR4 double sided circuit boards for solid construction and durability. Made in the USA. 

HD3000 Power Amp: 

The HD3000 amp delivers an impressive 2200W bridged at 4 ohms providing plenty of power. Its clarity surprises everyone with its fast 50uv output stages delivering superb natural sound. It's designed to run at 2 ohms delivering 1100w per channel, 550w at 4 ohms (2200w bridged) and 340w at 8 ohms (bridged 1100w). Features include 94% efficient CLASS D amps, 100 Hz subwoofer crossover, built in limiters protecting drivers and balanced 1/4" and XLR inputs and Speakon™ and binding post outputs. The 2RU rack aluminum chassis holds the weight down to 9 pounds. 

Unlike comparable amps in this price range, the HD3000 is fused at 15 amps allowing you to get the full rated output at 2 ohms/channel or 4 ohms bridged. The best news is that it's made in the USA where nothing else in its category is manufactured.
