about the a/d/s/ subwoofers

This manual covers four a/d/s/ powered subwoofer models. The C10ps and the C12ps use 10 and 12-inch subwoofers in sealed enclosures. The HT10ps and the HT12ps also use 10 and 12-inch drivers respectively, and feature precision-tuned bandpass enclosures for enhanced low-frequency performance. The C-series subwoofers have an attractive black matte finish that blends well into most decors. The HT-series subwoofers feature a black wood grain furniture grade finish.

These subwoofers are designed to be used with in-wall, bookshelf, or miniature satellite loudspeakers, extending the bass response of the system by an octave or more. The crossovers in the subwoofers can relieve the satellite speakers of the demand of reproducing the deep bass portion of the sound range. The combination of an a/d/s/ subwoofer and high-quality full range speakers produces a system that has the bass response and output level of much larger loudspeakers, in a compact, easy to place format.

The subwoofers can be driven by either preamp level or speaker level input signals. They can be connected to nearly any audio system.

The amplifiers in these subwoofers are capable of producing very high peak current levels. Sophisticated protection circuitry protects the amplifier and woofer if the subwoofer is operated in a manner that might cause damage. In addition, the amplifiers feature an array of controls that make it easy to adjust the subwoofer so it integrates seamlessly with the main speakers in the system.

The HT-series a/d/s/ subwoofer cabinets have a sophisticated tuned bandpass design. The speaker in the cabinet is mounted between two chambers. One chamber is sealed. The other is vented through special high flow tuned vents to the rear of the cabinet. This computer optimized hybrid design gives the transient response of a simple sealed box system with the efficiency and power handling of a vented box design. The result is clean and dynamic bass at all listening levels.

The speakers in the a/d/s/ subwoofers have an oxygen-free copper wire voice coil wound on a Kapton former for maximum efficiency and fidelity. The cones are acoustically inert and capable of moving large volumes of air without flexing or bending.

unpacking

These subwoofers are fairly heavy. Rather than lifting the unit out of the shipping carton, turn the open carton over and lift it off of the subwoofer.

Set the carton on a carpeted floor (or a large pad) with the top up and open. Hold the top flaps down against the outside of the carton. Carefully tip the carton onto its side and then onto the open top of the carton. Hold the inner packing material in place while turning the carton over to prevent the subwoofer from slipping out of the carton. Lift the carton off of the subwoofer. Remove the inner packing material. Then gently turn the subwoofer over onto the base. Save the shipping carton and inner packing material for future use. Moving or shipping the subwoofer in anything other than the factory carton can result in costly damage, which is not covered by the warranty.
