Spendor's technically advanced yet wholly musically satisfying D7 loudspeaker is another Spendor speaker that reviewers like to write about. This time it's the new linear pressure zone (LPZ) tweeter that better tracks leading edge transients that is getting the attention - there is better clarity of lyrics, and mushed treble cacophony is replaced by purely pitched differentiated clarity, and a new smoothness to this part of the frequency spectrum. This is perfectly integrated with a clean midrange and the right, tight bass. The new D1 speaker also uses the same LPZ tweeter
Spendor updated the A series with the A6R and A5R speakers, the latter of which features a closed box infinite baffle design that was found to give more even bass in smaller rooms. These typically have more complex room mode patterns making speaker placement more difficult. Today's Spendor speakers well balanced room friendly designs that will reveal true high definition recordings from those masquerading as such.
Spendor has always been associated with reference standard domestic and studio monitor loudspeakers since the sixties. The company's founder Spencer Hughes was involved with the development new materials such as Bextrene while working for the BBC that outperformed the paper cones of the day. After gaining the contract to provide the BBC with reference-standard, monitor-quality speakers such as the Spendor LS3/5 and BC1, domestic versions were made available to the consumer market and achieved cult status.
Under the capable leadership of current owner /designer Philip Swift, Spendor has launched several highly regarded series of speakers; the S, SA/ST and A, and updated classic series models, that have received excellent speaker reviews in the past few years. The combination of built-in-house cabinets with fit and finish beyond reproach, matched drivers and cross-over designs made under strict quality control in the UK, is part of the reason. The other big part is that with such experience, Spendor has the art to manufacture really great natural sounding loudspeakers and not just rely on engineering and analytical measurement.
One of the noticeable characteristics of Spendor speakers is the faithful tracking of a wide frequency bandwidth from low to high acoustical output
levels thus preserving the relative contribution of harmonic and sub-harmonic frequencies and hence the natural timbre of instruments.
This engages the listener into truly layered sound stage between soloist and accompanist and provides an enjoyable experience even at lower volume levels. Spendor uses very high quality components within a critically optimized cross-over to achieve this.
Careful management of the bass and seamless integration of the treble provides for a very coherent sound and helps the speakers disappear. The BBC always considered the midrange to crucial for good sound reproduction since the ear is most sensitive to this part of the frequency spectrum.
Todays high definition digital and analog sound sources demand even more from loudspeaker manufacturers and Spendor fully meets these requirements by building speakers with even greater definition while preserving the great transparency and natural non-fatiguing presentation they have always had.
