Infinity Intermezzo 4.1t (2000–2005)

The Intermezzo 4.1t was Infinity’s top floorstanding model in the Intermezzo series, a line built around the company’s CMMD™ driver technology — ceramic metal matrix diaphragms that Infinity claimed offered exceptional rigidity and transparency. The speaker paired a 1-inch CMMD dome tweeter with a 6.5-inch CMMD midrange and two 6.5-inch CMMD woofers, all mounted in cast frames within an internally braced cabinet. The enclosure used Infinity’s patented “TrapGun” design, which split midrange and bass loading into separate internal chambers to distribute resonance. Frequency response was rated at 27 Hz–40 kHz, sensitivity at 92 dB, and nominal impedance at 4 ohms. Recommended amplifier power ran 50–200 watts. Gold-plated binding posts allowed bi-wiring or bi-amping, and a ±1 dB tweeter level adjustment gave a bit of room-taming flexibility. Finished in black, silver, or cherry, each cabinet measured 1090 × 250 × 380 mm and weighed 31 kg.

Sources disagree on the crossover. The most detailed spec sheet (B. Audio) and a reseller listing (EAC) both cite a 4th-order Linkwitz-Riley network at 300 Hz and 2800 Hz. Audio Heritage gives a 1st-order design at 300 Hz and 2000 Hz. Two corroborating sources outweigh one, so the 4th-order Linkwitz-Riley figure is the one used here. The discrepancy is flagged for anyone restoring or modifying one.

Owner reports are uniformly positive. One reviewer on Audio Review, who came from Klipsch RF-3s, called the 4.1t "in a different league," and another described the CMMD drivers as "some of the most transparent drivers available." The speaker was praised for performing well with a "reasonably small footprint" for a floorstander of its ambitions. Audio (October 1999, p.178) covered the Intermezzo line around its introduction and placed it among the notable loudspeaker releases of that season.

No original retail price survives in the record. The production span of 2000-2005 comes from a corporate profile and may reflect the company range rather than this specific model's introduction, so treat those years as approximate. The used market occasionally turns up units in excellent condition - a Japanese HiFiDo listing showed one - but current pricing is thin. The record is otherwise clean: no common failure modes, no parts shortages, no maintenance warnings documented.
