Features

Gold Plated Input Connectors



The HT-12 input connectors are gold plated for superior
corrosion resistance and high electrical conductivity.

Patented LD/HP



The McIntosh low frequency loudspeaker element fea­tures the patented LD/HP motor structure. This design,
when compared to conventional loudspeaker elements,
reduces distortion significantly. It also increases power
handling and efficiency.

Shielded Magnetic Field



The HT-12 may be used in Home Theater installations
near a television receiver or monitor without causing the
television image to degrade. McIntosh has designed spe­cial shielding around the magnetic structure of the HT-12
Loudspeaker Element to prevent interference.

High Power Handling



The Loudspeaker Element of the HT-12 is chosen for
use with powerful amplifiers up to 400 watts.

Installation

Locating The Subwoofer

The optimal method for selecting speaker locations includes
the use of a real time spectrum analyzer (RTA) operated by
an experienced system installer. Refer to figure 1. An un­compromising installation would take into consideration the
floor, wall and ceiling coverings, the type and placement of
furniture and can even include the architectural design of
the room and its construction materials. The frequencies
reproduced by the HT-12 Home Theater Subwoofer are
non-directional. The HT-12 does not have to be placed aim­ing directly at the listener; however, it will sound best lo­cated toward the front of the room and away from corners.
Placement in certain spots in rooms with multiple similar
dimensions can cause undesirable bass reinforcement
known as standing waves. Experimentation with the place­ment of the HT-12, combined with careful listening, will re­sult in the smoothest bass response.

High Efficiency



The Loudspeaker Element used in the HT-12 Home
Theater Subwoofer has also been designed for high effi­ciency. As a result, any McIntosh Power Amplifier, even
our smallest, will provide satisfying room filling sound.

Automatic Overload Protection



The HT-12 has built-in Loudspeaker Element Protection
in the form of an automatic resetting solid-state device.
