The big breakthrough features of the XTEQ are its proven tracking down converter amplifier, its long throw, high back-electromotive force drivers, and its fully automatic room equalizer. Taken together, these unique features provide these subwoofers with as much bass as you would get from several 15 inch drivers mounted in a cabinet the size of a small refrigerator. Defining the standard of quality today, the XTEQ series also brings a suite of premium audiophile features to the table, like advanced auto turn-on circuitry, Anti-Walking Tread Design Feet™, gold plated connectors, soft clipping circuitry, and variable crossover level and phase control, making the XTEQ the foundation for any great home theater and audio system.
