These speakers are a part of the Utah Series, known for their exceptional sonic performance, durability, and versatility.

The mid-range section of the 668-0028B speakers is handled by a 10-inch (25.4 cm) woofer, engineered with a butyl rubber surround for increased durability and improved resistance to wear and tear. The cone is made of a proprietary polypropylene material, which provides a balanced frequency response and excellent power handling capabilities. The voice coil is made of aluminum, ensuring efficient heat dissipation and stable performance under demanding conditions.

The high-frequency response is handled by a 1-inch (2.5 cm) titanium diaphragm compression driver, which delivers clear and articulate highs with excellent detail and dispersion. The driver is mated to a horn designed with a carefully engineered flare and a waveguide that provides controlled directivity and uniform coverage.

The 668-0028B speakers are bi-amplified, allowing for separate amplification of the mid and high-frequency drivers, resulting in improved sound quality and increased efficiency. They can be used in a variety of configurations, including stand-alone, flown, or ground-stacked, making them a versatile choice for different applications.

The enclosure is made of 15mm (0.6 in) birch plywood, providing a rigid and stable platform for the drivers, minimizing resonance and ensuring accurate sound reproduction. It also features a rugged, powder-coated finish that protects against environmental hazards and wear and tear.

The 328132 Ampex Crescendo amplifiers are a powerful and efficient choice for driving the 668-0028B speakers. These amplifiers deliver a total power output of 2,000 watts RMS (4,000 watts peak) and feature a Class AB design for improved efficiency and reduced distortion. They also offer several protective features, such as overcurrent and overvoltage protection, ensuring reliable operation and long-term durability.
