The driver complement includes an 8-inch woofer with an integral phase plug for the LF and the company’s PRD500 5-inch ribbon driver for the HF. The ribbon tweeter has 120-degree horizontal and 30-degree vertical dispersion, allowing for a wide sweet spot. A user-selectable limiting circuit can protect the woofer from over-excursion. The LF amplifier has 180W of power; the HF amp provides 40W. Response is rated at 44 to 20k Hz (±2 dB). Retail is $1,495 each.
SLS PL6/PL6C SERIES
November 2004—Offering enhanced sonic performance for in-wall and in-ceiling installs, both new models include a PRD Planar Ribbon HF driver and a polycomposite woofer with Santoprene surround, which provide the extended frequency range necessary for the accurate playback of high definition music. In addition, the system offers uniform coverage over the entire frequency range with an extra-wide “sweet spot” for maximum full-range coverage.
SLS PS8R POWERED STUDIO MONITOR
November 2004—Building on the award-winning S8R line of studio monitors, the new PS8R powered studio monitor uses a unique amplifier topology that lowers distortion, increases bandwidth, and improves noise performance over traditional amplifier techniques while maintaining high efficiency. Additionally, each amplifier has been customized and matched to power the S8R drivers with appropriate headroom, damping, and uniform response.

The MF and HF drivers are mounted on a rotatable panel, which allows the speakers to be used horizontally or vertically, with the woofers oriented above, below or on either side of the mid/high section. The 26x36x12.5-inch (WxHxD) cabinet weighs 136 pounds and is capable of 121 dB continuous SPLs (127dB peaks!). Response is rated as 35 to 30k Hz (±2.5 dB); retail is $3,000 each.
November 2002—A new offering from SLS is the S1066, a high-SPL monitor with dual 12-inch woofers, twin 6.5-inch mids and the large PRD1000 tweeter.
