Klipsch KPT-1802-HLS

THE INDUSTRY'S ONLY FULLY HORN-LOADED, VENTED SUBWOOFER FOR THE GRANDEST AUDITORIUMS

The Klipsch KPT-1802-HLS cinema subwoofer uses a patented, horn-loaded vented cabinet design with an 18” driver, resulting in class-leading acoustic output combined with commanding sub-20Hz bass response previously unattainable from even a 21” driver configuration system.

• An industry-first horn-loaded vented cabinet design
• High-efficiency with very low distortion perfectly complements today’s digital sound formats
• 130dB continuous output capability

As a personal note, this is one of the cleanest subwoofers you will hear.  It's just very large and doesn't dig quite as deep as some people would like in a home environment.  The basic premise is that they built a ported 18" sub then wrapped a horn around the entire unit.  We often use them with Crown XLS amps, that's really all you need.  

There are no returns on these, they take up two pallets and are entirely too expensive to ship back and forth.  Please measure all of your doors, including interior and exterior.  They are 48" tall, 72" wide, 31" deep, and weigh 330 pounds.  You need at least 34" doors preferably 36" to get it in.  Measure before you order, not after they're sitting in your garage.
