Infinity RS 6000
The Infinity RS 6000 is a four-way floorstanding loudspeaker, reviewed by Stereo Review in 1979. It was a top RS Series model with a dual-woofer three-way configuration per High-Fidelity (April 1987, p.50). It's a fairly big design. A 12-inch woofer in a tuned enclosure handles the bottom end up to 150 Hz, where a 4-inch cone midrange takes over. A 2-inch dome tweeter covers the upper mids, and a 1-inch dome supertweeter takes over above 8,000 Hz. Crossover points are 150 Hz, 2,500 Hz, and 8,000 Hz. Rated sensitivity is 92 dB, nominal impedance 8 ohms, and power handling is listed at 100 watts. Frequency response is spec'd from 30 Hz to 35 kHz.
Stereo Review's reviewer found the overall sound "satisfyingly smooth and well balanced," with excellent frequency balance, and noted the power handling capability was far beyond what would be necessary for home listening. The reviewer also measured a system resonance around 50 Hz.
The RS 6000 sits in an odd spot in Infinity's lineup. It's not an EMIT-equipped Reference Standard model, but it shares the family character. Owner reports describe deep, clean bass from the 12-inch woofer, a lifelike midrange, and highs that come close to the EMITs, though slightly harsher. The soundstage is reportedly bigger and more realistic than smaller Infinity models, particularly with orchestral music and large-scale rock.
Known quirks and failure points, per owner experience:
- The midrange driver's foam surround deteriorates. It's a common failure, but replacement surrounds are available and the repair is fairly straightforward.
- The 1-inch dome tweeter is a known weak point and tends to fail if overdriven. Replacement tweeters are hard to find and expensive. They were shared with other Infinity models of the period.
- The midrange and tweeter level control pots (potentiometers) can get dirty and cause crackling or intermittent sound.
- A full recap of the crossover is recommended for long-term ownership, as the capacitors drift out of spec with age.
The cabinets are sturdy and well-damped, with a steel front baffle and vinyl finishes that can be refinished if needed. These speakers want solid-state power. They handle a lot of it and play loud, but they're not a good match for low-powered tube amps. The model number appears in sources as both "RS 6000" and "RS-6000" interchangeably.
