OverviewTweeter

The HRS-SAT4 and HRS-SAT4C are high performance loudspeakers, specifi- cally designed to provide high output and high performance for your home theater. Years of research and decades of ex- perience have gone into these amazing loudspeakers.

Sunfire created the category of small- box, high-power subwoofers more than a decade ago with the original True Subwoofer. This design relies on high- pressure, “High Back-emf” technology that provides very high bass output from a very small box. When migrating this subwoofer technology to the midrange and high frequencies on these HRS loud- speakers, you get the same advantages: high output, small size, high efficiency, and years of trouble-free operation.

Woofers

The “Trifilar” voice coil (actually 3 dual voice coils wound in parallel) has a much higher output than conventional multi-layer voice coil designs, and is also significantly lighter. This, combined with the lightweight and incredibly-strong Kevlar® cone, means that the driver responds very quickly. As a result, drum kicks, and other percussive effects will sound tighter and more lifelike. Having a lightweight woofer means that it has im- proved top-end response. This makes for smoother integration with the tweeter in the critical upper midrange, lower treble range – where much of the vocal informa- tion lives. As a result, vocals and dialog sound very natural – not muffled or tinny.

The woofer's 1" excursion is up to four times that of conventional woofers, and provides the highest power handling in its class.

The cast aluminum basket offers more rigidity than the typical stamped variety. When driven at high volume, they will not flex, and the result is tight bass at high volume, with very low distortion.

The tweeter used in both the center and surround loudspeakers represents a unique approach to tweeter design that results in unrivaled performance. It shares design elements with tweeters found in very expensive European loud- speakers, and has a frequency response that is flat to above 20 kHz for crystal- clear detail from any source.

The 1" ring radiating silk dome offers instantaneous response and wide disper- sion. The tweeter's vented back chamber contributes to high power handling, improves frequency response with lower distortion, and provides superior transi- tion from high frequencies to the critical midrange.

Cabinet and baffle

The woofer(s) and tweeter are mounted to a cast aluminum front baffle that is clamped to the cabinet from the rear, forming a fully-sealed enclosure. This clamping design produces a stiff cabinet that is very resistant to vibration, result- ing in tight bass response, high fidelity reproduction, and high output for music and movies.

Nine layers of paint and clear coats provide an elegant finish with protection and scratch resistance, and matches the finish of the HRS subwoofers.

Optional satellite stand

Specially designed for the HRS-SAT4, these optional stands follow the cabinet shape, and produce an inte- grated, one-piece look. The stand has an attractive high- gloss lacquered base and painted aluminum column.

Speaker wires are hidden inside the column, for a sleek finished product.
