Sonance has designed two new in-wall subwoofers exclusively for home theater systems. The new models, SUB12-500 and SUB10-250, join the existing Cinema Series in-wall and in-ceiling speaker line.

The 12-inch SUB12-500 and 10-inch SUB10-250, which are available this month, are three-piece systems featuring a high-performance woofer and grille integrated into a vibration-free enclosure with an outboard mono amplifier. Both models have been designed for CEDIA installation professionals who have requested sub bass performance while maintaining an aesthetically pleasing slim profile. The Cinema Series in-wall subwoofers feature Sonance’s Visual Performance micro-trim grilles.

Construction Details
Sonance Cinema Series In-Wall Subwoofer enclosures are constructed from a combination of half-inch and one-inch MDF for superior isolation of bass and extruded aluminum bracing for minimal obstruction of airflow inside the enclosure.  Mass damping of front and back walls of each enclosure and long strand fiberglass internal damping for standing wave dissipation is also incorporated. In addition, a floating enclosure design minimizes vibration transfer to adjoining rooms. Both enclosures fit in a standard 2x4 stud bay and a blank pre-construction plate is included for easy installation.

Low-Profile Drivers
The Cinema Series In-Wall Subwoofers feature a low-profile driver with an ultra-low distortion motor and four-inch diameter voice coil, according to Sonance. The Cinema 12-500 incorporates a 12-inch woofer, while the 10-250 utilizes a 10-inch woofer. Dual central mount spiders are used in both models to maximize the linear movement of the laminated carbon fiber honeycomb woofer cone.

The four-inch diameter voice coils were chosen for two reasons,” said Sonance chief speaker engineer Todd Ryan. “First a large-diameter voice coil will be able to continuously handle high levels of power and absorb all the power from the new digital amplifiers. The second reason was to allow us to place the spiders on the inside of the voice coil. In most shallow woofers due to the short distance from the surround to the spider the cones have a tendency to rock. This rocking requires the use of a larger gap in the motor to reduce the output of the driver. In our design, the spiders are placed at the center of the driver and connected to a post which is bonded to the cone.”

Class D Amplifiers For Continuous Power
The outboard Cinema Series subwoofer amplifiers feature a Class D output stage, line and speaker level high-pass filtering and are designed specifically to complement the SUB10-250 and SUB12-500 drivers and enclosures. Each amplifier is capable of driving up to two woofers.

Performance
Sonance says that the SUB10-250 extends down to 30Hz, and using the matching SUB10-250D amplifier it is capable of producing 108dB of output at one meter. The SUB12-500 extends down to 25Hz and using its matching SUB12-500D amplifier it is capable of producing 114dB of output at one meter.
