Sound Character

The Infinity RS II delivers the expansive and highly resolving presentation expected from a large Reference Standard loudspeaker.

The dual 10-inch woofers provide substantial low-frequency authority and scale, giving the system the ability to reproduce bass instruments, drums, orchestral foundations, and large-scale recordings with impressive physical presence.

The three dedicated midrange drivers provide a broad and articulate presentation through the vocal and instrumental range. Vocals, acoustic instruments, guitars, piano, and orchestral instruments can sound highly detailed and spatially convincing when the speakers are properly positioned and driven.

The EMIT high-frequency system is one of the defining characteristics of classic Infinity loudspeaker engineering. Its extremely lightweight diaphragm design allows the RS II to reproduce high frequencies with excellent speed, detail, and openness.

The result is a large-scale presentation with strong bass authority, detailed midrange information, and extended high frequencies.

Because the RS II is a large multi-driver loudspeaker system, it benefits greatly from careful positioning, appropriate room size, and stable amplification.

With the right amplifier and room, these speakers can deliver an expansive soundstage with strong dynamics and impressive resolution while retaining the distinctive character of classic Infinity engineering.

Actual Condition

The speakers are in Very Good vintage cosmetic condition.

The cabinets show the natural signs of age that can be expected from vintage high-end loudspeakers, including possible light scratches, small marks, minor edge wear, or other cosmetic imperfections accumulated over the years.

The large wooden cabinet surfaces, front baffles, driver panels, grilles, Infinity badges, and rear sections are shown clearly in the photographs.

The driver surfaces are carefully inspected, including the dual woofers, midrange drivers, and EMIT high-frequency units.

Because these are vintage speakers, minor differences in cabinet finish, wood grain, aging, and cosmetic appearance between the two speakers are normal and should be expected.

Please review all photographs carefully as they are an important part of the description and provide the most accurate representation of the actual pair being offered.

Important Note for Buyers

Vintage high-end speakers are precision audio components and require proper amplifier matching, careful handling, and appropriate placement to perform at their best.

The Infinity RS II is a large 4-ohm multi-driver loudspeaker system and should be paired with an amplifier capable of providing stable power into a demanding load.

Do not connect these speakers to an amplifier that is not suitable for a 4-ohm load or operate them beyond the capabilities of the amplifier.

The EMIT high-frequency drivers are specialized vintage components and should be handled carefully. Avoid touching or applying pressure to their delicate diaphragms.

Because these are large floorstanding speakers, adequate clearance and stable placement are important for safe operation.

We do our best to describe each pair clearly and provide detailed photos so you can buy with confidence.

Please review all photos, read the full description, confirm the amplifier compatibility, and contact us with any questions before purchase.
