Description

Precise and engaging Infinity RS2 bookshelf speakers from the 1990s, offering exceptional clarity and accurate sound reproduction in a compact design.

These Infinity RS2 bookshelf speakers deliver remarkable audio performance with their well-balanced sound signature. The two-way design features a 6.5″ polypropylene woofer with butyl rubber surround that provides tight, controlled bass, while the 0.5″ soft dome tweeter reproduces crystal-clear high frequencies. Audiophiles appreciate these speakers for their neutral sound character and ability to present music without artificial coloration.

The rear-ported enclosure enhances low-frequency extension, allowing these compact speakers to produce surprisingly full-bodied sound despite their bookshelf size. Their 89dB sensitivity makes them compatible with a wide range of amplifiers, though they shine when paired with quality electronics in the 15-100 watt range.

These speakers are known for their excellent imaging capabilities and accurate soundstage presentation. Many owners report using them as studio monitors due to their honest sound reproduction that doesn’t exaggerate any particular frequency range. Their compact form factor makes them versatile for placement in various listening environments.

Infinity was founded in Los Angeles in 1968 by aerospace engineers Arnie Nudell and John Ulrick, with Cary Christie, and its first speaker was the electrostatic Servo-Statik. We carry Infinity towers, bookshelf speakers, centre channels and subwoofers. We've had more than 45 Infinity listings so far, covering more than 30 different models.

Our best-selling Infinity models so far: the Beta 40 towers, then the Interlude IL25C centre, IL30 and IL40 towers and IL36C centre.

The Infinity story

Arnie Nudell and John Ulrick, aerospace engineers at Litton Industries, left with Cary Christie in 1968 to build speakers, starting in Nudell's garage. Their Servo-Statik combined electrostatic panels with a servo-controlled woofer, an idea from their aerospace work, and sold for $2,000 a pair.

EMIT and the reference years. In the late 1970s the Quantum line and the low-priced Qa, Qb and Qe brought in Infinity's EMIT tweeter, a flat plastic diaphragm with etched conductors, and Stereo Review called the $145 Qa one of the best loudspeaker values on the market. Infinity's flagship reference systems arrived at the end of the 1970s, and in Canada its speakers came in through Gray Acoustics of Markham, Ontario.

Harman. Infinity has been part of Harman International since the mid-1980s, and Samsung has owned Harman since 2017. The Kappa, Reference, Interlude, Primus and Beta lines followed through the 1990s and 2000s. In North America, Infinity now sells mainly car and marine audio.

Which Infinity is which?

1970s high end: the Servo-Statik, Monitor and Quantum models.

1970s and 1980s budget: the Qa, Qb and Qe, and the InfiniTesimal mini speakers.

Reference Standard and Kappa (1980s to 1990s): many numbered RS models, and Kappa towers and subwoofers.

Interlude (2000 to 2001): the IL10 bookshelf, the IL30 to IL60 towers, the IL25C and IL36C centres and IL subwoofers, with Infinity's ceramic metal matrix drivers. Infinity lists the IL30 and IL40 as made in the USA.

Primus and Beta (2003 to 2010): such as the Primus 250 and 360 towers, and the Beta bookshelf speakers and subwoofers.

Later lines: Cascade, Classia, TSS and the Reference series of 2014.

Buying used Infinity: what to check

Swap channels first. Infinity's own advice: if one speaker of a pair is silent or distorted, swap amplifier channels. If the fault follows the speaker, look for a loose wire, a bad crossover or a bad driver.

Crossovers. Inspect the crossover board for parts that look burnt or bulged.

Tweeters. Check that every tweeter, EMIT tweeters included, plays at low and moderate levels.

Powered models. Test the bass amplifier of any powered subwoofer or tower at volume.

Parts. Infinity lists no replacement parts for models such as the Interlude series, so replacement drivers come from donor speakers.

Everything we list is inspected, tested and serviced as required here, and comes with our warranty.
