It is a two-way system with two 5-inch low frequency and two 1-inch dome tweeters. The HT-3 is designed to work as Surround Loudspeaker in a Home Theater System. The HT-3 Loudspeaker performance is equivalent to the quality of McIntosh's legendary line of Amplifiers, Preamplifiers, Signal Processors and Signal Sources, without imparting distortion or coloration of its own. It also complements the capabilities and the remarkably low distortion of McIntosh Power Amplifiers. To reproduce sound accurately, all forms of distortion, both harmonic and intermodulation, must be kept to a minimum. This has been the result of the design of the new McIntosh HT-3 Loudspeaker System. Each loudspeaker element and crossover component has been carefully designed for durability, efficiency, and above all, low distortion. The McIntosh HT-3 Loudspeaker System will function as an excellent Home Theater Loudspeaker Surround Loudspeaker. · Minimum Visual Impact The HT-3s offer a unique solution to the problem of integrating superb surround sound into a room without drawing attention to the Loudspeakers. The removable metal grilles can be custom painted or wall papered to perfectly match your decor. · Sealed Enclosures A sealed solidly braced enclosure is used in both the Surface Mount and Flush Mount version for superior sound and freedom from bleeding into adjacent rooms. · Gold Plated Input Connectors The HT-3 input connectors are gold plated for superior corrosion resistance and high electrical conductivity. · THX® Approved The HT-3 Surround Loudspeaker System meets and exceeds the performance requirements of the THX Standard for the best possible reproduction of a film sound track that was originally created for use in a movie theater. Performance Features · High Performance Drivers Each HT-3 enclosure contains two 5-inch Polypropylene Low Frequency Drivers and two 1-inch Aluminum Dome High Frequency Drivers arranged in an Antiphase Dipole, Mirror Image configuration. · Special Crossover At frequencies below 350Hz both Low Frequency Drivers operate in-phase; above 350Hz both the Low Frequency Drivers and Tweeters operate out-of-phase thus providing the desired diffused surround effect. Both the Low and High Frequency Drivers are crossed over at a 12dB per octave rate. · High Efficiency The Loudspeaker Elements used in the HT-3 Loudspeaker System have also been designed for high efficiency. As a result any McIntosh Power Amplifier, even our smallest, will provide satisfying room filling sound, yet they can be used with amplifiers up to 200 watts.

The Surround Loudspeakers are intentionally designed to create a very diffuse sound field. The HT-3 uses a dipolar radiation pattern to achieve this performance. A dipole loudspeaker radiates sound both forward and backward, with acoustic nulls located at the vertical center of the enclosure. If a dipole loudspeaker is placed such that the listeners are seated within the nulls, they will hear surround sound only after it has been randomly reflected off of the walls of the room. The listener will perceive no specific direction for surround sound. Refer to figure 1. ing the HT-3 Loudspeakers so that the listener is not on the null of the system but perhaps 20 degrees forward or backward of the null.
