Unison Research MAX 2 2-Way Floorstanding Loudspeaker at Vinyl Sound Buffalo, NY USA

The MAX 2 is a 2-way floorstanding loudspeaker from Unison Research (Treviso, Italy), available at Vinyl Sound in Buffalo, NY, USA. Engineered specifically to partner with Unison Research's own valve amplifiers, the MAX 2 optimizes both sensitivity and impedance to extract maximum performance from low-powered tube designs while remaining equally capable as a front-channel loudspeaker in home theater installations. Its 15-inch woofer and 1.4-inch compression driver with titanium diaphragm achieve a sensitivity of 96 dB at 2.83 Vrms/1m, a nominal impedance of 8 ohms, and a frequency response of 30-20,000 Hz. The front-firing reflex duct simplifies room placement by eliminating the need for rear-wall clearance typically required by rear-ported designs.

Designed for the Valve Amplifier Era

The MAX 2's defining characteristic is its 96 dB sensitivity -- one of the highest available among contemporary floorstanding loudspeakers of its size. This figure is not simply a specification; it is an engineering commitment to the belief that a loudspeaker should present its amplifier with the most efficient load possible, allowing even a 10-watt tube amplifier to fill a large room with effortless, undistorted sound. The 15-inch woofer -- loaded in a front-firing bass reflex enclosure -- delivers the full extension and control in the bass octaves that smaller-format drivers cannot replicate. Its substantial internal volume provides the necessary air mass for bass frequencies to develop naturally, producing full extension down to 30 Hz. The 2-way crossover topology assigns everything above 800 Hz to the compression driver, with woofer low-pass at 12 dB per octave and tweeter high-pass at 6 dB per octave.

Versatility Across Two-Channel and Home Theater Systems

While designed as a dedicated two-channel music loudspeaker, the MAX 2 adapts naturally to home theater use. Its high sensitivity and large-scale dynamic capability mean that a pair used as front-left and front-right channels can produce cinema-level impact without requiring a subwoofer or center channel -- the full-range bass extension of the 15-inch driver and the wide dynamic envelope of the compression driver together replicate the roles of both components. Two pairs of MAX 2 cabinets (front and rear) create a high-impact home theater presentation of exceptional coherence. The front-firing port allows both music and cinema installations to be positioned against or near rear walls without acoustic penalties.

Key Features

• 96 dB Sensitivity: Exceptional efficiency makes the MAX 2 ideal for use with low-powered valve amplifiers from as little as 10 watts, while remaining capable with amplifiers up to 200 watts RMS.
• 15-Inch Woofer: A large-format bass driver provides full extension to 30 Hz and substantial dynamic headroom for both music and home theater applications.
• 1.4-Inch Titanium Compression Driver: The titanium diaphragm tweeter section handles high frequencies with detail and control, crossed over at 800 Hz for seamless integration with the woofer.
• Front-Firing Reflex Port: The bass reflex duct fires forward rather than rearward, greatly simplifying room placement and eliminating the minimum rear-wall clearance required by traditional rear-ported designs.
• 8-Ohm Nominal Impedance: A benign, stable impedance characteristic (7.4 ohm minimum) makes the MAX 2 an ideal amplifier load for both tube and solid-state designs.
• Home Theater Capable: Two pairs (front and rear) create a complete high-impact home theater system without requiring a center channel or subwoofer.
• Italian Craftsmanship: Designed and manufactured in Treviso, Italy, within the Unison Research / A.R.I.A. Srl production facility.

Frequently Asked Questions

What is the Unison Research MAX 2?

The Unison Research MAX 2 is a 2-way floorstanding loudspeaker from Treviso, Italy, using a 15-inch woofer and a 1.4-inch titanium compression driver, with a sensitivity of 96 dB at 2.83 Vrms/1m and an 8-ohm nominal impedance. It is designed primarily to match Unison Research valve amplifiers and produces a frequency response of 30-20,000 Hz through a front-firing bass reflex enclosure.

How does the MAX 2 compare to the Unison Research MAX 1?

The MAX 2 uses a 15-inch woofer crossed over at 800 Hz with a 6 dB/octave tweeter high-pass, reaching 96 dB sensitivity. The MAX 1, by contrast, uses a 12-inch woofer crossed over at 2,000 Hz with a 12 dB/octave tweeter high-pass, achieving 94 dB sensitivity. The MAX 2 is the larger, higher-sensitivity model better suited to large rooms and very low-powered amplifiers; the MAX 1 offers a slightly more compact footprint with the same reflex design philosophy. Both share the front-firing port and titanium compression driver topology, but the MAX 2's lower crossover point and higher sensitivity give it an advantage with single-ended tube amplifiers of 10 watts or fewer.

Can the MAX 2 be used without a subwoofer?

Yes. The MAX 2 extends to 30 Hz from its 15-inch woofer, which covers the vast majority of musical bass content and most film soundtrack low-frequency effects. In most listening rooms, a subwoofer is unnecessary. For home theater setups, Unison Research specifically notes that two pairs of MAX 2 cabinets -- front and rear -- produce an impactful surround presentation without requiring a center channel or subwoofer.

What is a compression driver, and why does the MAX 2 use one?

A compression driver is a high-frequency transducer in which the diaphragm drives a narrow throat or waveguide rather than radiating directly into open air. This loading increases efficiency dramatically, allowing the compression driver to produce more output from a given input power than a conventional dome tweeter. In the MAX 2, the 1.4-inch titanium compression driver complements the woofer's high sensitivity and extends the overall system efficiency to 96 dB, a figure achievable in a 2-way design only through the use of a compression driver format.

What amplifiers pair best with the MAX 2?

The MAX 2 pairs optimally with Unison Research's own valve integrated amplifiers, including the Simply 845, the Sinfonia, and the Performance/Anniversary, all of which operate in single-ended or parallel single-ended Class A topology. Its 96 dB sensitivity means even a 10-watt SET amplifier can drive the MAX 2 to realistic listening levels. Solid-state amplifiers up to 200 watts RMS or beyond are also compatible. The 8-ohm impedance (7.4 ohm minimum) presents a stable, non-reactive load that suits a wide range of output transformer configurations.
