David Vivian<\/strong> discovers if an unassuming, slim and starkly functional two-way speaker can deliver the Spendor sound in full<\/span><\/h2>\n

If any Brit-fi speaker maker’s reputation precedes it, Spendor’s is probably a nose ahead of the rest.\u00a0 The company was founded in the late sixities by the titular Spencer and Dorothy Hughes and its first speaker, the now legendary BC1, more-or-less set the bar for every mid-sized monitor that followed.\u00a0 Indeed, the company says the influence f that seminal design can still be heard across its current three-tier lineup, which continues to be designed, engineered and built in Great Britain.\u00a0\u00a0Spendor is rightly proud that it makes its own drive units, but unique in having its own cabinet-making plant in the UK.<\/span><\/p>\n

With its four-strong entry-level A-Line family, the aim is to bring Spendor know-how, craft and experience to a wider audience \u2013 albeit one that understands the deal and that \u2018price led\u2019 isn\u2019t part of the plan. Take the range-topping A7 on review here. From a distance, it looks too simple and plain for a speaker just under \u00a33k. No sexed-up drivers, no curvy cabinet panels. Zero bling.<\/p>\n

If you measure value in terms of material real estate, the A7 simply isn\u2019t going to float your boat, but fans of neat and petite should appreciate its modest height and footprint and take comfort from Spendor\u2019s assertion that it sounds anything but small. Making life more convenient still, the fourth-generation Spendor linear flow port, at the base on the rear, is said to work even quite close to a boundary.<\/p>\n

\"\"<\/p>\n

If the stark \u2018nude\u2019 aesthetic of the exposed driver units doesn\u2019t quite\u00a0click with your de\u0301cor, there are magnetic speaker grilles, but they\u2019re listed as an optional extra. The cabinets are beautifully built and immaculately hand finished in black ash, dark walnut or, as here, natural oak real wood veneers. Satin white is also available for an extra \u00a3300.<\/span><\/p>\n

The 180mm mid\/bass driver is a new Spendor design with a polymer cone and revised surround and suspension materials said to deliver exemplary thermal and mechanical stability. High power handling and good low-level linearity were also
\non the job sheet. It\u2019s paired with Spendor\u2019s 22mm \u2018wide surround\u2019 tweeter, which strives to combine the extended frequency response of a small diaphragm with the low- frequency characteristics of a larger diaphragm, the intended upshot being stable, low distortion response over a very wide frequency range. Wide dispersion is also claimed, broadening the listening \u2018sweet spot\u2019. The crossover network has been\u00a0afforded the same level of refinement. It features precision-wound, high- linearity tapped inductors which are said to avoid the distortion caused by attenuating resistors and allow very fine tuning of both frequency and phase response, necessary to achieve a coherent, balanced sound.<\/span><\/p>\n

The gathering weight of opinion challenging the convention that speakers should have high density cabinet panels and mass damping to minimise \u2018cabinet talk\u2019 finds a powerful advocate in Spendor, which joins with Russell K and Fyne Audio among others in arguing that with this type of build, spurious energy is stored and released slowly, sitting on timing and rhythmic snap. There are numerous cures that eschew internal wadding and unnecessary mass. Spendor\u2019s is called Dynamic Damping and uses small, low-mass constrained polymer dampers in the cabinet that \u201cconvert the spurious energy in the cabinet into inaudible heat\u201d.<\/p>\n

More than just a distinctive feature of Spendor\u2019s A-Line and D-Line ranges, the base of the speaker has four machined steel stabiliser inserts set directly into the cabinet. The reason, states Spendor, is that any micro movement or flexing of the plinth and feet blurs fine detail and destroys ambient cues and the sturdy metal perimeter prevents that, especially if used with the chunky supplied adjustable spikes (see Q&A).<\/p>\n

Sound quality<\/strong><\/span><\/p>\n

\"\"As Spendor claims that the A7 doesn\u2019t require a large space to deliver its best game, most of the auditioning is conducted in my smaller listening room, hooked up with my resident\u00a0Cambridge Audio CXC CD transport (HFC 401), Chord Electronics Hugo 2 DAC (HFC 428) and Rega Elex-R integrated amp (HFC 420). As ever, the speakers sit on Townshend Audio Seismic Podiums (HFC 426).<\/span><\/p>\n

The first CD up for inspection is the one that\u2019s closest to hand, but I\u2019m rather glad it\u2019s Michael Jackson\u2019s Scream compilation because Thriller neatly generates a broad first impression. Maybe just a hint of BBC reserve and polite neutrality? Nowhere to be heard. On the contrary, the A7 sounds much bigger and bouncier than you\u2019d ever guess from looking at it, with well-projected presentation combining truly impressive bass weight and extension with terrific agility and tunefulness. This is not to be confused with the kind of artfully revved up presentational style that blows you away for 30 seconds then gradually becomes harder to take seriously. No, with an appropriate dose of volume from the Elex-R, it\u2019s what a natural sense of life, pace and musical verve sounds like and keeps you wanting more.<\/p>\n

Dextrous jazz fusion guitarist Larry Coryell went through a phase of fridge-chilled funk in the mid-nineties and, thus flavoured, his version of<\/p>\n

the St. Louis Blues from I\u2019ll Be Over You challenges a speaker\u2019s ability to\u00a0capture contrast with a striking and very sudden change of mood. The track begins in true gritty acoustic blues fashion \u2013 spare, steely guitar phrases; Don Harrison\u2019s gruff, slightly echoey vocal; simple mic placements for authentic atmosphere. It all sounds raw, tactile and dripping with attitude through the Spendor. But\u00a0<\/span>37 seconds in it\u2019s as if a group of renegades from Funk Central crash through the roof and hijack the track with extreme \u2018dig this\u2019 prejudice. Coryell\u2019s faithful Gibson Super 400 electric guitar is joined by Chuck Loeb on rhythm, Mark Sherman on keyboards and Zach Danziger on drums and bluesy angst is replaced with a rich, smooth, densely layered groove in a heartbeat. The A7 just isn\u2019t fazed by the jokey suddenness of the stylistic shift, but seems to be in on the conceit, delivering a sonic wink in the form of an opening bass note sweep with visceral presence and extension that all but dives through the floor. The whole thing hinges on delivering just the right amount of dynamic emphasis and<\/span>the A7 absolutely nails it.<\/span><\/p>\n

\n
\n
\n
\n

It does so time and again. But the svelte Spendor also has a special talent for the small stuff \u2013 not just its command of musical nuance and laser-locked precision with timing, but its ability to resolve subtle ambient cues right down to the noise floor. It all makes for an addictively transparent, engaging, rhythmically sussed and endlessly enjoyable loudspeaker.<\/p>\n

\n
\n
\n
\n

Conclusion<\/strong><\/span><\/p>\n

Anyone who thinks Spendor is a bit old-school stuffy needs to hear the A7 urgently. Leave your preconceptions at the door. It sounds modern in the best possible way: fast, clear and open with fine dynamic expression, great bass and an unerring instinct for the musical pulse.<\/p>\n<\/div>\n

DV: What is the secret to the A7\u2019s great sound?<\/strong>
\nPS: Look behind the A7\u2019s simple exterior and you\u2019ll find a wealth of Spendor engineering innovation focussed on achieving a natural engaging sound. Examples include our EP77 polymer cone mid\/bass driver, which is exceptionally free from break up and resonance, our unique crossover topology with three-port inductors, which allows us to create a loudspeaker with a very linear phase response as well as a flat frequency response and our dynamic damping, which eliminates spurious vibration in the cabinet structure.<\/p>\n

\n
\n
\n
\n

What are the advantages of the design of the rear reflex port?<\/strong>
\nThe large rectangular port is smoothly integrated into the bottom structure of the cabinet. It eliminates many of the limitations of a conventional tubular reflex port. Air flow velocity is much lower so there is less distortion and higher head-room, group delay is substantially reduced and the low frequency response is more extended and even. Because the loudspeaker behaves very predictably when it is placed close to a wall or in a small room, it gives the A7 an unrivalled ability to deliver deep articulate bass, with a natural engaging sense of musical timing, in almost any listening room.<\/p>\n

What contribution does the built-in, spiked metal plinth make to the overall performance?<\/strong>
\nThe base of each plinth has four machined steel stabiliser inserts. Our threaded floor spikes can be quickly and easily fitted and adjusted by hand to compensate for any unevenness in your floor. Simple finger tightening of the spike lock nut against the steel plate secures the spikes so they won\u2019t vibrate loose. The stabilisers are secured directly into the main structure of the cabinet so that micro- movement or flexing of the plinth and feet \u2013 which blur fine detail and destroy ambience \u2013 is eliminated, the improvement in sound definition compared with a conventional spike\/foot arrangement is significant.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
