We are very pleased to help publish ‘Touch Wood’, the accompanying book to the exhibition of the same name, which will be running from 17th–20th October at Dray Walk Gallery in London. The show is aiming to raise money to protect threatened habitats, restore tropical forests and reduce our carbon footprint. Proceeds from the show and book will be donated to the World Land Trust, patroned by Sir David Attenborough.

Born out of a deep love for nature, the project, imagined and curated by Thomas Danthony and Clare Mabin, showcases a community of artists, designers and illustrators who have been asked to express what nature means to them by contributing an original piece of art, created on a wooden board.

Designed by Sarah Boris this beautiful book reproduces the work contributed for the show and includes pieces by artists such as Jean Jullien, Malika Favre, Hey Studio, Virginie Morgand and many, many more. Referring back to the meaning of the expression ‘touch wood’, they may be perceived as lucky charms. We will need more than luck, but we hope this small gesture, in the form of art, will help to safeguard nature.

You can pick up a copy of this book here: https://www.counter-print.co.uk/…/all-b…/products/touch-wood

🙏 Big thanks need to go to a number of people for making this book happen. As well as those mentioned above and all the contributors, we’d like to thank Fedrigoni for the beautiful stocks, ‘Freelife Cento’ and ‘Woodstock’ and for helping us offset the carbon for the paper. Thank you to Foilco for supplying the stunning cover foil and to Team Impression for the wonderful print job!

Alumine Five of Stenheim

Stenheim is a relatively late entrant to the high-end speaker field. It was founded in 2010 by a collective of mainly ex-Goldmund engineers, and its products have inherited an unmistakable aesthetic and, to a lesser extent, sonic DNA, although it was a significantly evolved character that was to emerge in the shape of the debut model, the compact, two-way Alumine Two. It’s a developmental divergence that has continued and, if anything, accelerated with the emergence of each subsequent product. The latest Stenheim speakers, developed under the auspices of new owner Jean-Pascal Panchard, definitely have their own, unambiguous identity, both visually and musically.

I’ve been seriously looking forward to the arrival of the Alumine Five. Previous experience with the brand has included impressive exposure to the various versions of the enormous and enormously impressive Ultime Reference models, as well as a brief but highly rewarding flirtation with the stand-mounted Alumine Two in my own system. The possibility of combining the sense of musical articulation, enthusiasm and communication I experienced from the Alumine Two, with more than a hint of the clarity, scale and authority so effortlessly delivered by the Reference models, all in a package that, if not exactly affordable, at least isn’t completely out of the question, makes the Alumine Five a distinctly interesting proposition.

Yet, confronted with the Alumine Five in the flesh, there’s little to hint at the extraordinary promise lurking within. Resolutely rectangular in true Stenheim style, the Five’s aluminum cabinet, with its plate-to-plate construction, stands just 48" tall, 15" deep and presents a broad 11" face to the world, dimensions based on golden-ratio numbers. The front baffle is split by a physical break between the upper midrange-treble enclosure and the lower bass cabinet, independently ported by the laminated full-width slots above and below, a physical separation that is mirrored by the contrasting inlaid strips that help visually break up the one-piece side panels. The regular lines, smooth surfaces, flawless matte finish and lack of visible fixings could easily result in a bland, almost featureless appearance. But those trim strips and the offset midrange and treble drivers do just enough to give the Five a subtle hint of individual style without resorting to the sort of gauche and ostentatious flourishes that so often pass as design.

The result is a refreshingly clean, classical appearance that will blend seamlessly with a range of different decors. Despite the lack of grilles (although they are available as an option, does anybody really spend this kind of money on a speaker and then compromise the performance by fitting covers?), the beautifully profiled baffle and absence of visible fixings makes for a genuinely neat, finished appearance that matches the superb surface finish on the cabinet. The end result just looks right, in a way that makes you wonder why you’d want grilles anyway.

The first hint of its potent sonic capabilities comes when you try to pick it up. Each comparatively compact cabinet tips the scales at 220 pounds. That’s a grunt-inducing, two-man lift. Now, take a look at the figures for bandwidth and sensitivity, and an in-room response that digs down as far as 28Hz combined with 94dB efficiency should raise your eyebrows, especially given the compact cabinet dimensions. Which brings us to the first experiential disconnect: boxes this size shouldn’t produce this much bass or do it so easily. Nor should they weigh so much -- although therein lies the clue to this particular conundrum. When it comes to bass extension, it’s not the external dimensions of the box that matter, but its internal volume. Just like the Crystal Cable Minissimo, a thin-wall cabinet makes for a much larger internal volume than the external dimensions might suggest -- especially if we apply the expectations of more conventional wood-based construction. Throw in the sheer weight of the aluminum panels and the combination of mass and physical dimensions would subconsciously suggest massively thick walls -- and a correspondingly limited internal volume. Instead, what we have here is a deceptively large volume, which, combined with the inertia of the heavy cabinet and the mechanical stability provided by the material, makes for an effective mechanical reference for driver movement, meaning that more of the energy your amplifier sticks into the speaker comes out as sound and (at least in theory) it will be more precisely rendered.

So far, not very much that’s new. It’s not like Stenheim (or Magico, or YG Acoustics) has exclusivity when it comes to aluminum cabinets. But what does make Stenheim different is the unique material they use in damping their cabinet panels. Of course, the separate enclosures and the internal baffles they demand make for an inherently heavily braced structure, but look inside a dismantled Alumine Five and you’ll find strategically placed pads stuck to the cabinet walls. These three-layer, self-adhesive pads combine a heavy damping layer (adjacent to the cabinet wall itself) with added foam and impervious layers, allowing the low-volume pads to influence both the mechanical behavior of the cabinet itself and the enclosed volume. It’s an interesting solution because it manages to overcome the weakness so often audible in simple, braced aluminum cabinets (the all-too-recognizable resonant signature of the material itself) while maximizing the benefits (large volume and rigidity) by obviating the need to stuff the internal space full of wadding or long-haired wool. In fact, if the Stenheims were stood behind a sonically transparent curtain, you’d be hard-pressed to recognize the music as emanating from an aluminum cabinet at all. The absence of the bleached, grainy or lean colorations, the lack of sterile, mechanistic reproduction, is one big half of the Stenheim story, living, breathing proof that it’s not what you use but how you use it that counts.

The other half is down to the drive units, and after the cabinets, those come as quite a surprise, both the lineup and the chosen materials. In stark contrast to the use of the latest, precision CNC techniques, complex damping pads and finishing options, the Alumine Five's drivers are as traditional as they come, with a coated silk-dome tweeter and pulp or laminated paper midrange and bass drivers. The cone drivers use textile double-roll surrounds and massive magnets more normally found in pro-audio applications, and while Stenheim doesn’t build its own drivers, the company works closely with its chosen supplier (PHL, definitely not one of the usual suspects) to specify the electrical parameters, mechanical characteristics and precise details of the surface coating.

The use of such lightweight cone materials and large motors aids the system efficiency, while a hybrid second-order/Linkwitz-Riley crossover, the result of extended listening and evolution, ensures phase coherence and excellent out-of-band attenuation and makes for easy non-reactive load characteristics, despite the three-way topology. The other aspect of the driver lineup that might be considered slightly unusual is the use of a large-diameter (6 1/2") midrange unit -- although less so since Vandersteen’s patent on the approach lapsed some years ago, resulting in a rash of companies suddenly exploring the possibilities of the topology.

Perhaps more important, in the case of the Alumine Five, it means that you are getting the tweeter and midrange drivers from the Ultime Reference series speakers, teamed here with a pair of 10" woofers but without the benefit of a super tweeter. Even so, Stenheim quotes bandwidth out to 35kHz, which should suffice for most purposes. The review speakers arrived with the optional second set of terminals installed, allowing for biwiring or, more significantly, biamping, an upgrade opportunity that makes this an option you should take. If, in the meantime, you are single-wiring the speakers, make sure you factor in a set of jumpers that match your speaker cables: the Alumine Five's overall sense of musical coherence makes the benefits especially obvious. Likewise, good wiring practice is essential, both in terms of cable dressing and diagonal connection (red to midrange/treble, black to bass, with jumpers arranged accordingly).

Aside from the speaker's substantial weight, the parallel sides and flat surfaces of the four-square cabinet make setting up the Fives an absolute joy. Precise, repeatable, angular adjustments are easily achieved, while changes in attitude are just as straightforward, helped by the beautifully profiled stainless-steel spiked feet and deeply cupped footers. Both the cones and their locking rings have nice, large ports to take the supplied pry bars, but it’s worth greasing the threads before installation. One other thing to watch out for: the spikes are seriously (refreshingly) sharp -- sharp enough to penetrate a thick rug and score the floor below, so be careful where you stand the speakers once the feet are installed. Final positioning disposed the speakers on a broad front with minimal toe-in. When it came to dialing in their considerable musical energy, the most critical factor proved to be height off the ground, with tiny adjustments of the spikes making profound differences to the weight and pace of the presentation. Likewise, equal weighting of the four spikes was crucial to a proper sense of grounded weight and dynamic authority.

明明可以用的地還有
明明要從需求落手，又不去做
一定要開發郊野公園，是何居心?!
.
一寸都不能少!!

【環保團體聯合聲明】
【Joint Statement from Green Groups】

反對開發郊野公園不接受「可加可減」
郊野公園具重要旅遊康樂及規劃功能港人重要綠色寶庫
應先善用棕土、軍營及閒置土地

Objection to Developing Country Parks and the Adjustment Mechanism
Make Use of Brownfield Sites, Military Camps and Spare Land

行政長官梁振英向傳媒公開表示，已指示政府部門就發展郊野公園作研究。環保團體對此感到十分憤怒，因為社會有眾多聲音明確反對開發郊野公園，政府當局仍然一意孤行，更為此目的投放資源作具體行動，是蓄意與社會製造矛盾。
.
香港仍有不少可作發展的土地，過去房屋問題只源自「分配不均」。政府多年來逃避檢討「丁屋政策」（為丁屋預留土地）、未有動用閒置的軍營、未有以「棕土優先」發展等，為導致目前情況的主要原因。政府亦沒有正視大量住宅單位空置及私樓單位成為投資工具的問題，是政府的政策出錯，卻以缺地作掩飾。明明有其他可行及有共識的可用土地，政府仍以老人家及公屋輪候冊上的人為人質，提出發展郊野公園，是絕不可接受。
.
郊野公園是香港重要的特色，亦是重要綠色寶庫，除包含保護珍貴生態的環境價值，亦有旅遊（香港的郊野公園世界聞名）、社會（供大眾休憩）、規劃（限制城市過度擴張）等重要功能。郊野公園亦是重要集水區，讓足夠雨水流入周邊的水塘，提供港人生命之源。郊野公園有大量樹木，吸收二氧化碳，抵銷部份因燃燒化石燃料產生的溫室氣體，紓緩全球暖化。郊野公園亦有無以彌補的珍貴地質地貌。
.
梁振英指可選取「生態價值較低」的地帶發展，我們並不同意。郊野公園的一草一木、花鳥蟲魚皆是生命，她們亦有自身存在的意義與價值，而生態價值亦沒有百份百客觀標準衡量。梁振英提出郊野公園「可加可減」機制，更是保育的「語言偽術」，。現存的每一片郊野公園的地理位置、地勢、環境及生態本來就獨一無二，不應被任何藉口取締，以另一處新郊野公園「面積」作交換是誤人耳目。
.
梁振英在未有善用棕土、軍營及閒置土地之前，就提倡開發郊野公園邊陲，是規劃目標錯誤。房屋問題亦不能單靠盲目覓地處理，亦需要同時透過人口政策，控制房屋需求來解決。大自然一旦遭破壞將無法復原，絕不應發展香港人引以為傲的郊野公園。

The Chief Executive Mr. CY Leung told the media that he has instructed relevant departments to conduct a study on developing country parks. Green Groups are furious and strongly opposed to this, as the public has already voiced opposition to the development of country parks. However, the government still insists on doing so and, furthermore, devotes more resources to this, deliberately leading to conflict within our community.
.
In fact, there is still a lot of land available for development in Hong Kong. The housing shortage problem has originated from “Uneven Distribution”. Over the years, the government has avoided reviewing the “Small House Policy” (land designated for New Territories Exempted Houses), unused Military Camps and Brownfield sites. These are the main reasons for the present situation. Moreover, the government has failed to address the problem of vacant housing units and private flats used for investment and speculation purposes, falsely presenting the situation as a “lack of land”. As there are other land resource options, it is totally unacceptable for the government to use the welfare of the elderly as an excuse for developing country parks.
.
Country Parks are important features and treasures in Hong Kong. Apart from the environmental value of preserving our precious ecology, they are also well-known for eco-tourism, community enjoyment (for public recreation) and even have a role to play in urban planning (for preventing over-expansion of the urban areas). Country parks are also important water catchment areas, which allow rainwater to flow into surrounding reservoirs. Furthermore, trees in country parks can absorb carbon dioxide and offset some of the greenhouse gas emissions from burning fossil fuels, which relieves global warming.
.
Mr. CY Leung pointed out that low ecological parts of country parks can be developed. We totally disagree with his claims. All the plants, flowers and birds in the country parks have their own meaning and value to the natural environment. Ecological value cannot be measured in objective criteria. He further suggested the “Adjustment Mechanism” in Country Parks, which we consider to be “weasel words” designed to mislead the public about conservation. The geographical location, the terrain, environment and the ecology of each existing country park are unique and should not be replaced by any excuses. The exchange of another “new” country park area is totally a mistake.
.
Mr. CY Leung hasn’t made good use of brownfield sites, military campsites or spare land before advocating the development of country park borders. Hong Kong’s housing problem could also be solved not just by finding land but also by controlling housing demand through a population policy. Once the natural environment is destroyed, it cannot be restored to what it was before. Therefore, the government should not develop our country parks, which are the pride of Hong Kong people.
