Architectural Specifications

The loudspeaker shall consist of a 133 mm (5.25 in) low-frequency transducer and a 25

mm(1.0 in) high-frequency transducer with a frequency-dividing network installed in the enclosure. The low-frequency voice coil diameter shall be 25 mm (1.0 in). Sound waves from the low- and high-frequency drivers shall be reflected from a 781 mm (30.75 in) Dual-Parabolic™ sound dome.

Performance specifications of a typical production unit shall be as follows: Usable frequency response shall extend from

95 Hz – 20 kHz. The loudspeaker shall be available in either voice coil/4 Ohm direct or 70.7/100 Volt models, and equipped with a corrosion-resistant binding post for pre-selected impedance modes. Taps should be nominally 4 W @ 70.7 V (8 W

@100 V), 8 W @ 70.7 V (16 W @ 100 V),

16 W @ 70.7 V (32 W @ 100 V), and 32 W @ 70.7 V (tap position not used @ 100 V). Transformer options are factory preset at 8 Watt, unless otherwise specified at time of order. The frequency-dividing network shall have a crossover frequency of 5 kHz. Rated power capacity of the components and network shall be at least 50 Watts conti- nous RMS.

FP633-T32, FP633-4 specifications

Phase Technology has long been recognized as a leader in the development of advanced audio technologies that deliver superior sound quality. Among their impressive product lineup, the FP633-4 and FP633-T32 stand out as exceptional offerings designed for both professional and home audio environments.

The FP633-4 is a four-driver, in-wall loudspeaker that features an innovative design aimed at achieving high fidelity in a discreet form factor. It is equipped with dual 6.5-inch woofers, a 4-inch midrange driver, and a 1-inch tweeter. This configuration allows the speaker to produce a well-balanced frequency response, ensuring that both low and high frequencies are rendered with clarity and depth. The dual woofers are designed to extend bass response while minimizing distortion, creating a rich listening experience that is ideal for music lovers and movie enthusiasts alike.

On the other hand, the FP633-T32 provides a more versatile solution with its three-driver configuration that includes a 6.5-inch woofer complemented by a 1-inch tweeter. This model, specifically tailored for multi-channel audio setups, excels in delivering dynamic sound across a variety of genres. The FP633-T32 is designed to excel in both stereo and surround sound configurations, making it a perfect choice for theater setups.

Both models utilize advanced technologies such as Phase Technology’s proprietary Acoustic Lens technology, which optimizes the dispersion of sound waves. This innovation ensures that listeners experience a wide soundstage regardless of where they are positioned in the room. Additionally, the speakers incorporate high-quality crossover networks that effectively separate frequencies, resulting in a clear and coherent audio reproduction.

Durability and design are also key characteristics of the FP633-4 and FP633-T32. They feature robust construction materials that allow them to withstand wear and tear while maintaining their performance over time. Their low-profile design makes them suitable for installation in various environments without compromising the aesthetics of the room.

In conclusion, the Phase Technology FP633-4 and FP633-T32 embody the brand’s commitment to delivering high-quality audio solutions. With their innovative technologies, advanced design, and outstanding performance characteristics, these loudspeakers are excellent choices for those seeking to elevate their audio experience, whether in a home theater or music listening context.
