THE NEWEST D MODEL
Forty-five years ago, Spendor developed the first loudspeaker with real transparency, articulation and natural sound specifically for BBC engineers who were mixing orchestras for live radio playback and needed to hear exactly what each musician was playing.
Over time and through their exhaustive R&D efforts, Spendor engineers achieved a series of technical breakthroughs and the company went on to become one of England’s leading loudspeaker manufacturers. Spendor continually developed landmark loudspeakers, always remaining true to the Spendor sound but also consistently improving transparency and thus creating “better” loudspeakers.
Three years ago, Spendor introduced the D7 which delivered an articulate, coherent and natural presentation, with a level of transparency never before heard in a conventional dynamic loudspeaker. As a result, the D7 became the most critically acclaimed Spendor ever, earning Stereophile’s coveted Class A recommendation - a remarkable accomplishment for a $6,500 loudspeaker.
Today, the new D9 takes the D7’s brilliance a step further. An elegant, modern, 3-way loudspeaker, the D9 delivers music with exceptional resolution and a vibrant realism with any genre. Easy to drive and highly efficient, the D9 is also remarkably flexible and can be placed in any living environment. This is a speaker 45 years in the making. This is the Spendor D9.

SPENDOR LPZ (LINEAR PRESSURE ZONE) TWEETER
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 age-old 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 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. The front plate also provides excellent mechanical protection for the delicate tweeter dome and a smart modern appearance.
NEW DRIVE UNITS DEVELOPED FOR D9
The D9 mid-bass drive unit has an advanced EP77 polymer cone mid-range drive unit. 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 drivers are in a large dedicated low-frequency acoustic enclosure.
Like Spendor’s highly regarded A9 loudspeaker (now superseded by D9) the D9 delivers accurate powerful bass without distortion or compression. All three drivers feature cast magnesium alloy chassis, high efficiency motor systems, optimized 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.
