Spendor D9 speakers (no grilles)


Spendor D9

SKU: 1.00E+13 Category:


We have two pairs of Spendor D9 speakers that were produced before the grille design was finalised. As such they have small holes for the grilled but no actual grilles. They were then eventually manufactured with magnetic grilles.

These are current models and there are no other differences between these and the current grille models. But the saving is immense. We have black and rosewood.

The new Spendor D9 is an elegant, modern, full-size, 3-way, 4-driver, floor-standing loudspeaker. The D9 delivers music with exceptional resolution and a vibrant realism that conventional loudspeakers cannot match. It delivers low frequencies with breath-taking power, scale and authority. It is easy to place in real-world listening rooms, very efficient, and compatible with all good amplifiers. With a tall slim enclosure and smart modern finishes the Spendor D9 is entirely at home in any living environment. The D9 incorporates all the engineering innovation developed for our 3-way Spendor D7 loudspeaker, but the new D9 is far more than just a big D7 . . .

Spendor loudspeakers, cabinets, crossovers and drive units are all designed and manufactured in-house in the UK. 



The goal of every tweeter designer is to achieve linear acoustic output over a wide frequency range. In practice this is extremely difficult. Spendor’s approach to this challenge is radical, and it works. The Spendor LPZ tweeter is built around a stainless steel front plate which forms a damped acoustic chamber directly in front of a lightweight woven polyamide

diaphragm. The front plate incorporates a phase correcting micro foil to equalise sound wave path lengths across the diaphragm surface. Simultaneously it generates a symmetrical pressure environment on both faces of the diaphragm so the tweeter always operates in a balanced linear mode. The front plate also provides excellent mechanical protection for the delicate tweeter dome and a smart modern appearance.

Imagine focusing an ultra-high quality camera lens until you see a clear bright image. That’s the effect of Spendor LPZ Technology. Our sequential geometry micro-foil operates like an acoustic lens. The result is perfect focus, uninhibited sound transmission and a very wide listening window. Sound images are vivid, in-the-air, as bright or sweet as any music demands. 


The D9 mid-bass drive unit has an advanced EP77 polymer cone. Housed in an isolated enclosure at the top of the cabinet, it handles only mid-range frequencies which eliminates mid-low frequency intermodulation. It delivers music with superb clarity and vanishingly low colouration. The two D9 low frequency drivers have ultra-rigid, two part bonded, lightweight Kevlar composite cone assemblies. The bass drivers are in a large dedicated low-frequency acoustic enclosure. This allows the D9 to deliver accurate powerful bass without distortion or compression. All three drivers feature cast magnesium alloy chassis, high efficiency motor systems, optimised electro-dynamic damping, and excellent thermal dissipation for wide dynamic range. New polymer surrounds with very stable molecular composition reduce driver break-in time significantly.


When extended low frequency sound reproduction is the goal there is simply no substitute for volume. In the D9 low frequencies are handled by two specially designed bass drivers in a substantial volume enclosure. For optimum low frequency response and power handling the enclosure is ported, but not like any conventional loudspeaker. The D9 incorporates our innovative Fifth Generation Spendor Linear Flow Port Technology. Inspired by Formula 1 diffuser technology it offers significant advantages over any conventional port or transmission line loading. An aerodynamically profiled central baffle, like an aircraft wing, creates a tapered twin-venturi port. Air at the port extremities is smoothly 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 linear 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. A carefully optimised combination of bass driver electrical and mechanical parameters, enclosure volume, air flow and wide-band (very low Q & very low phase shift) alignment allows the D9 to deliver deep, fast, articulate bass in a way no conventional loudspeaker can challenge.

High quality terminals are recessed within the port aperture to hide plug and cable connections. 


Conventional loudspeakers incorporate foam or fibre to provide low frequency acoustic damping. The damping material stores energy. As stored energy is released it is no longer intime with the original music and it creates an unnaturally, heavy, slow sound. Inside the D9 there is no low frequency damping, the sound path, from the bass drivers to the listening room, is totally unrestricted. Consequently, the Spendor D9 is entirely free from damping material energy storage effects. The advantage is clearly audible, music sounds naturally fast, agile and coherent.


Timing is a fundamental element of all music. In conventional loudspeakers rigid high density cabinet panels are mass-damped to reduce cabinet-talk. Spurious energy is stored and released slowly. This introduces unacceptable and unnatural blurring and slowing of the sound. Spendor’s solution is Asymmetrical Aperture Bracing to disperse internal waves and create a very rigid non-resonant enclosure, while Spendor Dynamic Damping with small low mass constrained polymer dampers at key energy interface points instantly convert any spurious energy in the cabinet structure into inaudible heat. The result is a silent rigid cabinet and a naturally fast engaging sound.


The base of each cabinet has four levelling feet attached via forged steel inserts to hold the cabinet rock-steady. The elimination of micro-vibration allows fine musical detail to be reproduced with delicate precision. 


A meticulously refined crossover network with precision wound inductors and high-linearity plastic film capacitors integrates the drivers seamlessly in a minimum phase alignment.

All crossover components and Spendor drive units are calibrated and matched to stringent broadcast reference standards. 


90dB efficiency and an easy to drive 8ohm load ensure complete compatibility with all good amplifiers and cables. With substantial power handling the D9’s can play very loud without compression. At low replay levels the sound is always clear and balanced.


The Spendor D9 looks as good as it sounds. Our special finishes perfectly complement today’s on-trend interiors. Spendor Dark, a diamond polished gloss lacquer over a dark natural veneer, for an alluring modern look. Satin white, a silky pure white lacquer, for a distinctive contemporary look. Dark ebony for a deep luxurious look, and natural rosewood
