found reassuring. I may or may not have wa r med to t he voicin g of a part icular model, but I’ve always respected what I’ve heard. So when cartons bearing the famil­iar orange JBL logo arrived on my door­step recently, I was eager to check out the company’s latest efforts.
midd le pr ice ran ge, a hotly c ontes ted market where prospec tive buyers know wh a t sound s g ood but don’t want t o spend stupid amounts of money to get it. I u npacked two ES80 towers, a n ES25C center speaker, two ES10 surrounds, and an ES250P subwoofer. With their sizable bulk filling my listening room, I expected significant sonic results.

The ES Ser ie s occ upies JBL’s uppe r-
The ES80 tower stands waist-high. Its
ES80’s five ver tical d rivers are a pair of 6-inch woofers, a 4-inch midrange, and a module wit h two covering the normal high-frequency range and the other covering ultra-high frequen­cies. This sa me module appe ars i n the other satellites as well. Two pairs of stout binding posts allow mono- or bi-amping. There’s also a rear-firing port.
The ES25C center speaker uses an MTM (midrange/tweeter/midrange) driver con­figuration, with a pair of 5-inch midranges flank ing the tweeter module. Adjusting the ported cabinet’s two feet can lower its vertical angle. The ES10 surrounds are direct-firing, with one 4-inch driver and the tweeter module. There are two mount­ing brackets on the back and two ports on top. Make darn su re the kids don’t drop pennies in there — or your car keys.
The ES250P subwoofer sports a f ront­firing 12-inch driver, a downwa rd-fi ring port, and an amplifier rated at 400 watts. Its control set prov ides adjust ments for level and crossover frequency (50 to 150 Hz with a 24-dB/octave slope), phase (0°

and 180°), and LFE/stereo line inputs. A switch toggles between LFE (for the mono low-frequency-effects channel on Dolby Digital and DTS tracks) and Norma l (for a regular stereo input), with the crossover adjustment bypassed when the former set­ting is selected. All six speakers are faced with removable black grilles.
SETUP
In stal ling t he JBLs didn’t present any unusual obstacles. I placed the ES80 tow­ers 10 f ee t apar t, about 1 fo ot out from the f ront wall, and toed them in to face the l isten ing position. Th e towers a re supplied with th readed spiked feet, but I used the included rubber feet instead. As with any floorstanders, the proximity of the d rivers to my tile f loor created a reflection t hat colored the direct sound path. To mitigate this, I placed throw rugs on the floor in front of each cabinet.
The ES25C center speaker went below my T V. Its vertical a ngle was good, so I didn’t adjust it s feet. I placed t he ES10 surrounds on speaker stands in the back of t he r oom. I wi sh they had the same adjustable feet as the center speaker so I could have aimed them down a bit.

The ES80 exhibits a 300-Hz floor-bounce notch that’s typical for tower-style speakers, along with narrow band irregularities up to 2 kHz and a 5-dB drop in level above 7 kHz. The ES25C center shows
and listening positions. From experience, I knew to place the ES250P in my room’s sub sweet spot, along the front wall and between the TV and the left tower.
MUSIC PERFORMANCE
I sta rted my critical listening with stereo playbac k, cou rtesy of KT Tunsta ll. Her debut album, Eye to the Telescope, was a bona-fide hit and proved t hat not all new stars need to be Idols. The JBLs reproduced the muscular ba ss guitar on Suddenly I See with good musicality; the subwoofer prov ided solid f undamental notes wh ile the towers woofers added the attack of the plucked strings. Likewise, the kick drum, pulled back in this mix, sounded steady and strong. The sat/sub blend was seam- less — one of the advantages of using tow­ers for t he lef t and right f ront chan nels, instead of small satellite speakers.
Tunsta ll’s lead vocal on t he song was clean, as was the touch of reverberat ion ar ou nd it. Detail s were clea rly audible, such as nuances in the vocal echoes on the line I can see her eyes looking from a page in a magazine. That I could hear all of this detail suggests good midrange clarity.
The snare sound was appropriately crisp and snappy, albeit a bit brighter than what I’ve heard on some other systems. The com­bination of t he nor mal t weeter a nd t he
similar irregularities between 800 Hz and 6 kHz, and its response tails off at 6 dB per octave above 6 kHz. It also has a deep (20 dB) notch centered at 3 kHz that extends from 1.6 to 6 kHz. Be assured that off-axis listeners won’t hear the same sound as someone sitting front and center. The ES250P subwoofer only has upper bandwidth of 103 Hz using the LFE input. When using the internal crossover, its response ranges from 52 to 81 Hz, even though the crossover is marked from 50 to 150 Hz. To its credit, the sub can deliver 105 dB SPL from 32 Hz upward.
Tom Nousaine
ultra-high-frequency driver served up lots of presence and air. The entire top end siz­zled with energy, and, in fact, it required a little getting used to. But once I got accli­mated, I was quite happy with that extreme high-frequency extension.
Expanding my audition to other faves bot h old and new, I worked t hrough my evaluation checklist. Imaging was accurate, with a good phantom-center image on pop lead vocals, and likewise the panorama of orchest ral instru ments was continuous across the stereo arc. The soundstage was open and natural, undoubtedly aided by the plentiful high-frequency response.
Turning my attent ion to music in sur­round, I listened to t he 6-channel mix on the DVD-Audio edition of Led Zeppelin’s How the West Was Won. On this album, the center channel is used lightly for lead vocals, but since the ES25C employs the same tweeter module as the towers, the high end sounded well matched. The center speaker’s 5-inch woofer falls between the towers’ 4- and 6-inchers, but its tonal qual­ity is similar enough. On other su rround albums, too, these drivers worked together to reproduce a realistic soundstage across the front, with good image definition.
MOvIE PERFORMANCE
JBL got its start in movie sound, so I wasn’t
surprised that its ES system handled with aplomb t he soundt rac k to Hero, a C hi­nese fantasy spectacle directed by Yimou Zhang. In one scene, the t itular cha rac­ter swirls around a blue room, cutting ties holding bu nd les of st ic ks. The swoosh­ing sounds of ou r flying hero, co-mingled with the ringing of his sword, are panned th roughout the sur round mix. Here, the satellite speakers provided great spat ia l continuity instead of the blobs of localized sound I sometimes hear on other models.
The subwoofer added to t he swirling sound w ith low-pitched whooshes — an effect that was nicely integrated with the satellites. (A lesser system might have stat­ically localized the low sounds to the sub, deg radi ng the sense of movement.) And when the sticks crashed to t he floor in all six speakers, the sense of immersion was complete. Meanwhile, dialogue ha rd- panned to t he center channel sounded absolutely clean. As I expected, the cen­ter speaker’s MTM configuration produced symmetrical horizontal dispersion.
BOTTOM LINE
In a world of tiny satellites — not to men­tion cute cabinets that a re subwoofers in name only — it’s comfor ting to listen to big, traditional speakers from a big, tradi­tional company. JBL has a speaker-design knowledge base thats almost unrivaled. If theres one thing it k nows how to do, its putting drivers in boxes and making them sound damn good.
