Spendor

The Spendor D7 is an elegant, modern, medium-size, 2.5-way, floor-standing loudspeaker, that combines distinctive modern styling with state-of-the-art engineering to deliver music with a fresh vibrant realism that conventional loudspeakers simply cannot match. This new level of performance is the direct result of important Spendor innovations like the Spendor LPZ (Linear Pressure Zone) tweeter.

Spendor says that the goal of every tweeter design is to achieve linear acoustic output across a wide frequency range, which has always been a tall order for engineers. Although Spendor’s approach to this age-old challenge is radical, it works.

Perhaps the most surprising speaker in the Spendor lineup is the Spendor D9, which has been introduced to rave reviews that it richly deserves.

At first blush, the D9 seems like a D7 model on steroids, but it is, in fact, so much more. Significantly improving upon the precision, detail and harmonic accuracy of the D7, the D9 adds a sense of scale, power and low-end response that is most commonly associated with bigger and more expensive floor-standing speakers, making D9 the best all-around floor-standing speaker we have yet heard under $15,000 per pair.

Spendor 18cm drive units developed for D7

The Spendor LPZ tweeter is built around a stainless steel front plate that forms a damped acoustic chamber directly in front of a lightweight woven polyamide diaphragm. The front plate incorporates a phase-correcting micro foil to equalize sound wave path lengths across the diaphragm surface. Simultaneously, it generates a symmetrical pressure environment on both faces of the tweeter diaphragm so the tweeter operates in a balanced linear mode.

Similar to focusing an ultra-high quality camera lens to bring up a clear, bright image, the LPZ’s sequential geometry micro-foil operates as an acoustic lens. The result is perfect focus, uninhibited sound transmission, and a wide listening window. The front plate also provides excellent mechanical protection for the delicate tweeter dome and a smart, modern appearance.

Spendor 18cm drive units developed for D7

The D7 mid-bass drive unit has an advanced EP77 polymer cone for superb clarity and vanishingly low coloration. The low-frequency drive unit has an ultra-rigid, two part bonded Kevlar composite cone assembly for accurate and powerful low-frequency response. Both drivers feature a cast magnesium alloy chassis, high efficiency motor systems, optimized electro-dynamic damping, and excellent thermal dissipation for a wide, dynamic range. The polymer surround significantly reduces driver ‘break-in’ time thanks to its stable molecular composition.

Fifth generation Spendor Linear flow port technology

The benefits of Spendor Linear Flow port technology have been well-proven in the Spendor A-line. They deliver deep articulate bass with natural timing, even in small rooms or close to a wall. The fifth-generation Spendor Linear flow port incorporates an aerodynamically profiled central baffle to create a tapered twin-venturi port. Air at the port extremities is decelerated and there is a further reduction in air velocity in the large tapered area at the cabinet base. The result is evenly-balanced acoustic pressure and air-flow along the whole length of the port. Rapidly decreasing air velocity at the port extremities creates an air-curtain effect to eliminate port noise and spurious mid-band radiation.

Conventional loudspeakers incorporate low frequency enclosure damping material, which stores energy that, when released, is no longer in-time with the music, making it sound unnaturally heavy and slow. The sound path within the D7 cabinet, from the bass drivers to the listening room, requires no low frequency damping and, therefore, the Spendor D7 is free from energy storage effects, resulting in clearly audible music that sounds naturally fast, agile, and coherent.

The Spendor A4 was designed for music lovers who demand a clear, captivating sound. Thanks to innovative Spendor technologies, the A4 allows for the very best sound, regardless of the equiptment its paired with.

At the heart of the A4 is a Spendor designed and engineered 7” bass-mid drive unit that features the same EP77 polymer cone and new surround developed for Spendor’s flagship D7 model. The driver has excellent power handling and excellent low-level linearity. Key electrical, mechanical and damping parameters have been optimized to ensure consistent low frequency performance and sound in any listening room, with any amplifier.

A meticulously refined crossover network integrates the drivers seamlessly to deliver vivid, dynamic, and natural sound. Spendor’s high-quality crossovers utilize custom inductors that avoid the distortion problem created by attenuating resistors and allow fine tuning of frequency and phase response. As a result, Spendor’s A Line loudspeakers achieve a coherent and balanced sound rarely found in loudspeakers within the same price point.

The Spendor A7 is a bigger and better version of the A4 that uses the dynamic damping system from Spendor's award-winning D Line as well as a twin-venture port developed specifically for the model. In addition, the A7 cabinet size is perfectly optimized for the main drive unit, delivering an open and rich sound with smooth mid-ranges and fast, deep bass.

At the heart of the A7 is a Spendor 7" bass-mid drive unit which incorporates key materials developed for Spendor's flagship D7 loudspeaker.

The completely re-engineered crossover has precision wound high-linearity tapped inductors which avoid distortion and allow fine-tuned frequencies and phase responses, for a coherent, balanced sound, deep articulate bass, and smooth natural highs with outstanding clarity.

A 22mm wide surround tweeter combines the extended frequency response of a small diaphragm with the low frequency characteristics of a larger diaphragm ensures a smooth, extended high frequency response over a wide listening area with fast, engaging sound and true transparency. The internal cables are high-grade silver plated pure copper with halogen-free dielectric. High linearity audio grade capacitors and an easy to drive 8ohm load ensure uncompromised performance and complete compatibility with all quality amplifiers and cables.

"A superb floorstander, one of Spendor's best boxes ever." - HiFi Choice, April 2013, Five Star Award Winner

"It has a decent helping of the original mid 1970s BBC magic midrange but with a modern twist. The D7 is easy to drive and truly compatible with valve amplifiers. Undemanding of placement, it has fine stereo and extended powerful bass, sounds upbeat and well balanced, and will drive larger rooms as required. And the build and finish is first rate: what more can one ask?” - HiFi Critic, September 2013
