It’s fairly common in the world of highend loudspeakers for a company to first use a newly developed technology in its flagship model, and only later apply that technology to its less expensive models. This practice is especially common in bigger companies, where ongoing research and development ensures a steady stream of new ideas and approaches. A good example is the Chorus 807 W ($1599 USD per pair), one of two bookshelf models in the Chorus 800 W Prestige series of speakers from venerable French manufacturer Focal. By combining design elements from their flagship Utopia and lessexpensive Chorus V models, Focal has created a series of speakers that bridges a gap between their midlevel and highend offerings. French fusion If you visit Focal’s website, you’ll likely notice that the Chorus 800 W and Chorus 800 V models look very similar. That’s because the same cabinet shape, produced by Parisian industrial design firm Pineau & Le Porcher, is used in both lines. The profile of the 807 W’s cabinet and the neckline of its grille are both in the shape of a V. In combination with the striking Red Carmin High Gloss my review pair came in, this gives the French speaker a very distinct personality. However, the V shape isn’t merely for appearance’s sake: the sides of the speaker gently taper in toward the rear, resulting in opposing nonparallel surfaces that help break up standing soundwaves inside the box a good example of form following function. The walls of the cabinet are made of MDF ranging in thickness from 0.8" to 1.0", and are internally braced to keep resonances at a minimum. Another similarity between the Chorus V and W series is that they share the same 1" TNV inverteddome tweeter. This updated version of Focal’s TNC tweeter was created out of what the company learned while developing the tweeter for their previous flagship floorstanding speaker, the Grande Utopia Be. Unlike the beryllium driver used in the Utopia, the TNC and TNV tweeters are made of an aluminummagnesium alloy said to have very good damping properties. Although the TNV is based on the TNC, it features several modifications, including a new foam surround and a redesigned neodymium motor system, all of which are said to reduce harmonic distortion to as little as onesixth that produced by the TNC. While the tweeter benefits from technology developed for the Utopia series, the 807 W’s highend pedigree is truly revealed by its midrange woofer. The cone of this 7" driver is made of Focal’s W material, a patented composite used in the Utopia line that comprises multiple thin layers of glass on both sides of a central foam layer. Together, these materials are said to produce a light yet rigid diaphragm with excellent selfdamping © SOUNDSTAGE!

By varying the density of the glass, the number of layers, and the thickness of the foam, Focal is able to adapt the W material to be used as a midrange driver, a woofer, or, as in the 807 W, a midrangewoofer. Both tweeter and midrangewoofer are made inhouse by Focal and are crossed over at 3kHz. Measuring 17 5/8"H x 9 1/3"W x 13 1/8"D and weighing 22.2 pounds, the 807 W is on the big side for a bookshelf speaker, though not obtrusively so. What makes you take notice of them is not size but style. When I first unpacked and set them up, I thought they looked a little too gaudy for my more minimalist tastes. However, as time went by I grew accustomed to them, and thought they looked pretty good in my room. While the top, bottom, and rear panels are finished in highgloss black, the buyer can choose from one of several finishes for the side panels, including French Walnut veneer, Black or White High Gloss, or the aforementioned Red Carmin High Gloss. Ultimately, a speaker like Focal’s Chorus 807 W Prestige will be more at home in a room with contemporary décor, where it can accent the space with its distinct personality, than it was in mine. Focal claims a frequency response of 50Hz–28kHz, ±3dB, for the 807 W, and a sensitivity of 92dB. Combined with its 8ohm impedance, the 807 W presents a very modest load for an amplifier; it shouldn’t be too difficult to drive. My 100Wpc integrated amplifier provided the Focals with all the juice they needed to come to life. To provide the 807 Ws with that power, a single pair of binding posts near the bottom of the rear panel accepts spades, banana plugs, or bare wire. I perched the 807 Ws atop 24"H Osiris stands and hooked them up to a Bryston B100 SST integrated amplifier with AudioQuest Type 4 speaker cable terminated in banana plugs. An NAD C542 CD player was used as a transport, its digital signal sent to the Bryston’s onboard DAC through an AMX Optimum AVC31 coaxial cable. I used a Thorens TD160HD turntable with Rega RB250 tonearm and Dynavector DV10X5 highoutput movingcoil cartridge to play LPs, and wirelessly streamed music from my Apple iMac computer through an Apple Airport Extreme to an Apple Airport Express. An XtremeMac XtremeHD TosLink cable connected the Express to the Bryston’s DAC. Everything was plugged into an ExactPower EP15A powerline conditionerregenerator.

The front baffles of the 807 Ws were thus 3.5’ from the front wall, and toed in so that their tweeter axes crossed just behind my head. I listened for a while and was underwhelmed by the way the Focals reproduced the oomph of a kick drum or the weighty tones of a bass guitar, so I moved them a foot closer to the wall. Listening to "Girl I Love You," from Massive Attack’s Heligoland (CD, Virgin 5 9466 2), I found that the bass had gone from a little too lean to a bit murky. It was definitely more fleshed out than before, but not as clear as I wanted. I can imagine some people preferring to keep the 807 Ws closer to the wall to get as much low end as possible, but I tend to favor bass definition over sheer bass output. I split the difference, leaving the 807 Ws with their front baffles 3’ from the front wall, and was rewarded with a broad, threedimensional soundstage with wellarticulated, sufficiently voluminous bass. This was evident on "Paradise Circus" (from Heligoland): the Focals produced a strong bass rhythm that provided a good foundation for Hope Sandoval’s voice. As handclaps emerged from behind the singer, the sense of the stage’s depth was palpable, and the whole sonic picture came into focus. Needless to say, I did the rest of my listening with the 807 Ws in these positions. Once they were set up properly, I was impressed by the 807 Ws’ reproduction of scale and impact. "Your Rocky Spine," from Great Lake Swimmers’ Ongiara (CD, Nettwerk 30691 2), emerged as a wall of sound spread across the front of the room. Strings sounded crisp, the bass was taut and punchy, and Tony Dekker’s voice was cleanly reproduced. The presentation of the band and their positions on the stage sounded coherent. The drum kit in "Backstage with the Modern Dancers" sounded especially good, conveying good impact but not as much bloom as I’ve heard from other speakers. Some listeners might crave more bass extension; positioning the Focals closer to the front wall will satisfy this to a large degree. No one will accuse the 807 W of sounding laidback or recessed; its sound was sharply detailed and prominent, almost unapologetic in its ability to get in my face and draw my attention. The voices in the title track of Atlas Sound’s Parallax (CD, 4AD 31302) were centered between the speakers, against a backdrop of gently strummed acoustic guitar, strange computer blips, and the crisp metallic resonance of shimmering cymbals. The Focals did a nice job of sorting out everything to produce a forwardsounding, highly immersive soundscape. Much of the prominence of the 807 W’s sound was a function of its extended high frequencies. Some speakers trail off a bit at the top end, but not the Focal. Rather than rolling off the treble, the 807 W soared well into its upper registers, which made its sound more incisive.
