Coverage note. Speaker Ranking currently covers 5 Infinity models across passive speakers and subwoofers. These are the products in our database, not a complete list of everything Infinity makes.
What this page covers. The Infinity models ranked here span passive speakers and subwoofers, including Infinity Speakers REFERENCE SUB R12, Infinity Reference R162 and Infinity Primus 360. Use each model’s category position to compare it with alternatives of the same size and use case.
This page lists all 5 Infinity speakers ranked on this site across passive speakers and subwoofers. Each model is shown in the category where it competes, with its current rank and the size of that ranking.
Use the category position rather than the brand name alone: speakers from the same manufacturer can perform very differently by size, price and product family.

Large Size Bookshelf Speakers
Ranked #67 of 134 in Large Size Bookshelf Speakers - Infinity Reference R162: $500 per pair Discontinued eBay
Pros: CEA2034 spinorama shows good directivity with wide, consistent horizontal and vertical response, and blended early reflections that need little room treatment. 1” CMMD waveguide tweeter and 6.5” CMMD woofer, 85.5dB sensitivity. Measured bass extension of 67.4Hz (-3dB), with a measured sensitivity of 87dB.
Cons: Elevated output above 3kHz adds brightness, with a resonance around 700Hz and some distortion near the crossover point. EQ or a simple inline tweeter resistor can tame the treble; the reviewer still called it a very enjoyable system for the price. Discontinued.

Ranked #87 of 134 in Large Size Bookshelf Speakers - Infinity IL10: $160 per pair used Discontinued eBay
Pros: Impressively flat for a budget bookshelf. Predicted in-room response is good aside from a bit of excess energy here and there. Distortion at 96dB SPL/1m stays low and controlled outside two narrow resonance-driven peaks. Measured bass extension of 59Hz (-3dB), with a measured sensitivity of 86dB.
Cons: Resonances at 600 and 5kHz, which show up as distinct distortion spikes at 96dB SPL/1m in the same frequency regions. Discontinued.

Large Size Floorstanding Speakers
Ranked #40 of 74 in Large Size Floorstanding Speakers - Infinity Primus 360: $650.00 per pair Discontinued eBay
Pros: A three-way tower from 2005 (two 6.5” mid-woofers, a 4” mid-range, and a 0.75” dome tweeter, 8 ohms nominal) that holds up remarkably well by modern measurement standards: on-axis linearity is within about ±2dB, and the listening window stays consistent out to roughly ±30° horizontal and ±10° vertical off the mid-range axis. Horizontal directivity is well controlled out to about ±75° before tonality starts to drift, meaning the reflected sound in a room stays close in character to the direct sound: a speaker that takes EQ well without fighting itself. Harmonic distortion measures low at both 86dB and 96dB, and multitone distortion stays under the reviewer’s 3% threshold. Silky, smooth midrange with a rich lower-midrange/upper-bass character. No mechanical issues or surround degradation found in a 20-year-old pair, and a second unit measured within about 1-1.5dB of the first, suggesting good long-term consistency for the design. Measured bass extension of 53Hz (-3dB), with a measured sensitivity of 89.4dB.
Cons: Manufacturer-spec sensitivity of 93dB runs about 3-4dB optimistic versus the measured 89.4dB average. Bass output drops off fairly quickly below about 50Hz in-room (F3 53Hz, F10 37Hz), so a subwoofer is needed for real low-end extension. Resonances show up around 170Hz, 220Hz, and 350Hz. On-axis, the lower treble can sound a bit bright or sibilant when the speaker is aimed directly at the listener; toeing out about 10-15° (rather than the more extreme 30°) gave the best balance, and some sidewall acoustic absorption further tamed a 4-5kHz peak. Placed close to the rear wall, bass gets boomy: pulling the speakers out about a foot resolves most of it, with roughly 1.5 feet from the wall as a good compromise between bass character and typical room aesthetics. Straying beyond about 25° above or below the mid-range axis introduces audible suckout. No longer in production, so it’s a used/secondhand purchase only.

Ranked #60 of 74 in Large Size Floorstanding Speakers - Infinity Reference 253: $400 per pair used Discontinued eBay
Pros: Horizontal beamwidth of about ±60 degrees is fairly smooth and well controlled. Really amazing value for the performance. Measured bass extension of 78Hz (-3dB), with a measured sensitivity of 86.9dB.
Cons: CEA2034 spinorama and predicted in-room response both show elevated treble above 4kHz (“too hot”), a dip around 2kHz, and bass shelved down relative to the midrange. Vertical directivity requires staying at or below the tweeter axis for accurate tonal balance. Distortion at 96dB SPL/1m is broadly elevated above the reviewer’s audibility threshold across much of the midrange. Minimum impedance dips to 4.2 ohms. Discontinued.
