October 2007 |

Harbeth. Say the name to any
music-lover or audiophile anywhere on the
planet and you’ll likely get a flicker of
light from their eyes and enthusiastic, almost
gushing, praise. There are few companies whose
products rate such universal and unanimous
acclaim. I’ve never met anyone who has
listened to Harbeth’s speakers who didn’t rate
them extremely highly. Considering the wide
range of tastes and styles among audio
enthusiasts around the world (and the US
audiophile community’s tendency towards
flavor-of-the month fads,) this universal
consensus is a significant and rare
achievement.
Harbeth’s success, moreover, is long-lived:
2007 marks their 30th Anniversary (a bronze
plaque on the back of my review sample Compact
7ES-3 speakers commemorates the fact.) The
company continues its tradition of highly
refined, musically consonant, and
true-to-timbre speakers that any music lover
will find easy to place, easy to drive, and
relatively easy to afford. And, as the
testimony of Harbeth owners repeatedly bears
out, easy to love. Many find themselves
appreciating their Harbeths even more after a
few years of ownership, when they find
themselves off the treadmill of that seemingly
endless Audio Upgrade/Holy Grail search for
“something better.” Harbeth speakers tend to
be final destination products for many owners,
allowing them to spend their time listening to
music rather than auditioning audio
components.
Harbeth’s tradition, as most know by now, is
rooted in the fertile alembic that was BBC
Research and Development, that creative
cauldron which inspired the formation of many
UK speaker companies and sourced many of their
founders. The BBC remains today one of
Harbeth’s largest customers. Current Harbeth
director Alan B. Shaw continues the high
ideals of Harbeth with an integrity that is
rare and admirable in today’s business world.
Demand for Harbeth’s products is extremely
high, yet Shaw maintains the perfectionist
quality-control the company is known for: no
geared up, quick-and-dirty production lines,
no slave-labor outsourcing to China, and no
artificially inflated “High End” prices.
The
new Compact 7ES-3 is the continued refinement
of the seminal Compact 7, the speaker which
introduced the Harbeth Radial™ 8-inch bass/mid
driver. The Radial™ driver was the result of
almost insanely intensive and tedious research
and development by Harbeth to find an ideal
driver material. The result was worth it: the
driver is considered by many to be the finest
of its type, its ability to correctly
reproduce the timbre of acoustic instruments
so natural and believable that many owners of
far more exotic and far more expensive designs
have switched to Harbeths and never looked
back.
The changes in the new Compact 7ES-3 involve a
new surround for the Radial™ driver, a
consequent change in cabinet loading,
refinements to the tweeter, and a new
cross-over. The rest of the Compact 7’s
salient features remain the same: cabinet size
and construction, sensitivity, frequency
response, and load are unchanged. The 7ES-3
uses single wire connection, as Shaw sees no
point in putting in bi-wire connection for a
design that does not benefit from it. The
crossover change allows a wider choicer in
speaker stand height without altering the
treble balance. Like all Harbeths, the Compact
7ES-3 is designed to be played with its grill
on. Build quality and quality of finish are
first-rate, in that grand UK craft tradition.
This is a speaker worth holding onto for
years. The changes to the speaker and the
vagaries of the US dollar/GB pound
relationship mean a price increase for US
customers. The Compact 7ES-3 now costs
$3295/pair in Cherry wood finish; Eucalyptus
finish costs $3595, Tiger Ebony $3795.
The new Compact 7 ES-3 is the fourth Harbeth
speaker I have reviewed; the others, in
sequence, being the Super HL5-here,,
the HP 3ES-2-here,
and most recently, the Monitor 30-here.
It was obvious within five minutes of
listening to the Super HL5, the first Harbeth
speaker I reviewed, that I was listening to
the work of a master speaker designer. Each
Harbeth speaker I’ve reviewed since has proven
itself a masterpiece, given its intended use
and room size application. The Compact 7 ES-3
upholds the grand Harbeth tradition: designer
Alan B. Shaw has hit the mark again.
Bulls-eye.
The new Compact 7ES-3 is the least expensive
Harbeth speaker to use the Radial ™ driver and
is designed to be used in small-ish to medium
sized rooms. Unlike Harbeth’s Monitor series
of speakers, the Compact 7ES-3 is designed
specifically for home listening and thus aims
at unalloyed appreciation of the quality of
the music, rather than analytically dissecting
how the recording was made. Though the
distinction between a home loudspeaker and a
studio monitor loudspeaker might be subtle
conceptually and need not ultimately be
mutually exclusive, Harbeth feels the
differences are significant enough to warrant
producing distinct loudspeakers for each
application.
The Compact 7ES-3 is slightly larger than the
Monitor 30 in size and goes slightly lower in
bass response, enough so that in the intended
room-size application (and even a bit larger)
the Compact 7 will reproduce the 42 Hz lower
limit of the double bass and bass guitar
clearly. Measurements in my very large
‘reference’ room showed flat response to 50
Hz, the beginning of the bass reflex-loaded
Radial ™ driver’s roll-off. Thus the 7 will
subjectively sound full-range, though the
bottom octave will be quite a bit down in
level. The Compact 7’s sensitivity falls in
between that of the mini-monitor HP 3ES-2 and
the Super HL5: an honest 50 watts per channel
into an 8-ohm load should be adequate to most
applications. The Compact doesn’t quite come
alive at the very quietest levels as well as
the Super HL5, but then it doesn’t need as
much amplifier drive as the HP3 ES-2 either.
The Compact 7 proved more accommodating to a
range of component quality than the rather
picky Monitor 30, though it wasn’t quite as
affable as the Super HL5, which has the rare
ability to extract the best out of all
components without spotlighting their flaws.
Potential owners of the Compact 7 aren’t
likely, however, to be tormented by trying to
find compatible amplifier, cable, and source
matches to use with the speakers. Although the
speakers are less sensitive than the
increasingly common new goal of 90 dB, the
speaker’s load appears very benign in
impedance and phase angles, making them easy
to drive by any competent amplifier.
I listened to the new Compact 7 in three
different sized rooms. The speaker was well
matched to medium and smaller rooms: If one of
your room dimensions extends much beyond 20
feet, the Super HL5 would probably be a better
match regarding bass support in the bottom
octave-and-a half. I used a variety of speaker
stands in a variety of heights. The new
crossover in the Compact 7 doesn’t require
laser precision in speaker-stand height to
achieve proper treble reproduction; gross
changes in height will likely more noticeably
result in bass response changes. I mostly used
the excellent and affordable Reference 3a
Solid laminated-wood stands, which permit
height adjustment from 19 inches to 30 inches.
I placed the Reference 3a stands on the
Stillpoints Universal Resonance Dampers, and
adjusted the stand height so that the
Harbeth’s tweeter was at ear level.
The first thing one notices when listening to
the Compact 7ES-3 is its simply wonderful and
natural-sounding mid-range – instruments sound
rich and full-bodied, with their full array of
harmonics intact. This is the kind of midrange
that often leads many listeners to purchase
tube amplification, yet the Harbeth achieves
its organic midrange performance even with
solid state gear. An accurate and natural
sounding midrange is essential to instrument
identification and vocal elocution, of course,
and the Compact 7 was simply magical in the
way it allowed the ear to identify
instruments, capturing their timbre and subtle
sonic signatures with an extraordinarily
natural ease. This was particularly so with
orchestral instruments whose frequency ranges
overlap. The speaker clearly differentiated
between the violin and the viola: Within the
woodwinds, there was zero tonal ambiguity
among the English horn, oboe, and clarinet, or
between the flute and piccolo. But the Harbeth
went further still: One could easily identify
the different makes of violins from the great
Cremona-based masters. The sonic signatures of
Fender, Gretsch, and Gibson electric guitars
were clearly rendered. It’s too easy to forget
that the live sounds of many instruments are
often simply beautiful in their own sonority,
a pure sensual pleasure to hear. The Compact
7ES-3 produces that beauty like few other
speakers. Being able to easily and accurately
identify the instrument playing is the
essential first step for any hi-fi system. The
rigorous experimentation and development that
went into creating the Radial ™ driver has
paid off: in terms of timbral accuracy; there
is no dynamic cone driver that matches it.
There is more to creating accurate timbre than
mid-range acuity by itself. The higher
harmonic overtones of the fundamental pitch
(note) that the instrument is playing extend
out into the treble range, making tweeter
quality and integration essential to the
instrument recognition process. The 7’s
tweeter sounded like an extension of the
midrange, in the usual Harbeth manner. The
high-frequency response of the Compact 7 did
not match the ultimate airiness and ease of
the Super HL5’s super tweeter, and while its
ultimate resolution lagged behind the Monitor
30’s, it also lacked that speaker’s analytical
sharpness. Overall, the treble does not draw
attention to itself. It’s neither prominent
nor absent. It’s simply there, as the music
requires.
Bass response was tight and very well
controlled when placed on the Reference 3a
Solid stands, with quick starts and stops to
bass notes, and no boom. This was true even
with my antique EICO 50 Watt per channel tube
amp, though admittedly this precise control
was only available when the amp was placed on
the Stillpoints Component Stand. The speed of
the bass does not sacrifice sonority for
acuity: the acoustic bass and cello were rich
and full-bodied.
Accurate instrumental timbre alone is not,
however, enough for complete musical
satisfaction: The depiction of what the
instrument is playing and how it’s playing it
ultimately determine the worth of a hi-fi
component. A truly great speaker helps us
understand the music and interpret its
meaning: It serves as a hermeneutic tool. The
Compact 7ES-3 is more than a beautiful face of
vivid instrumental sonority – it adds grace,
wit, fire, nuance, intelligence, and artistic
sensibility of the highest order.
Most middling hi-fi is fairly adept at
revealing the broad outlines of music, a kind
of abstracted generalization and
simplification of the music. Increasingly,
much current mass-market digital technology,
both for music playback and for computer
application, produces this kind of filtered
short-hand, using simplification to produce
its clarity. Not surprisingly, music
specifically produced for these formats (the
medium becomes the message) tends to the
synthetic and artificial. Tellingly, no one
actually plays a real instrument on much Rap
and Pop. Instead we have ‘samples,’ and
‘beats,’ drum ‘machines’ and various other
computer-synthesized sounds with almost zero
dynamic range, lock-step totalitarian rhythms,
and a complete lack of any of the emotional
inflection and artistic intent that reveals
the human being creating the music. (My recent
forced audition of an acquaintance’s iPod was
a descent into musical hell. Every instrument
sounded like a synthesizer, there was an
appalling lack of dynamic contrasts and of
rhythm and timing. It all sounded appallingly
robotic.) No wonder that Classical and Jazz,
just two kinds of music that rely on nuance,
expression, dynamic contrast and rhythmic
suppleness, are increasingly just blips on
contemporary sales charts.
Duke Ellington’s old adage that there are only
two kinds of music: good music and bad music,
bears revision. There is a third kind: great
music. To really appreciate, indeed to even
understand, good or great music requires more
than the simple outlines of the music. From
this standpoint, the primary goal of a hi-fi
is to reveal the quality of the music: The
greatest sin is aesthetic distortion. The
Harbeth Compact 7 ES-3 is exceptionally low in
aesthetic distortion: It reveals the inherent
merits of the music played through them -
good, bad, and great. To the simplest
requirements of the broad outline of music,
the 7’s add subtlety, nuance, expression, and
musical meaning. The Compact 7 reveals the
details of the playing, the subtlest of
inflections and touch.
I was pleasantly surprised at how well the
Harbeths performed with CD playback. It did
not exacerbate the format’s common weaknesses
in timbre reproduction, low-level detail, and
general rhythmic coherence. Moreover it did
this with even humble CD playback gear. The
Compact 7 was definitely more forgiving than
the Harbeth Monitor 30, or my own reference
Sound Lab Dynastats. Importantly, it achieved
this forgiveness without coloration and
opacity.
High-quality analogue LP playback more clearly
revealed the Harbeth’s ultimate strengths. One
of the stand-out merits of the Funk Firm
Vector turntable (which I’ve just reviewed) is
its ability to lay out the rhythmic
variability – the playing around the beat - of
the individual players in much Post-WWII Jazz
performance. The Funk and Harbeth combined to
not only clearly portray what each player was
doing in relation to the implied pulse, but
also how it related to the other player’s
variations of it. The Harbeths were equally
adept at portraying other music’s versions of
the technique – “in the pocket” drumming on
Rock and Roll, and rubato in Classical
playing. The 7’s were equally adept with
Groove-based music and with polyrhythms. The
Harbeth’s rhythmic performance is impeccable.
Given the 7ES-3’s superb rendition of timbre,
acoustic music of all kinds was predictably
easy and rewarding to listen to. Freed from
the aural chore of trying to identify the
instruments and to localize their position in
the sound field, it was unusually easy to
focus on what the instruments were playing and
how they were playing it. Phrasing and parsing
of musical lines was excellent, as was their
interplay, both melodic and harmonic. Even the
most difficult of Classical pieces and Jazz
performances yielded readily to understanding.
Judging the artistic merits of various
performances of a given Classical work was
easy and reliable: the Harbeths are an
invaluable aesthetic tool.
The Compact 7ES-3 offers an exceptionally
well-integrated blend of accurate timbre,
sophisticated rhythmic performance, highly
articulate reproduction of performance
technique, and clear insight into the artistic
intent of the music. That it can do this with
just about any kind of music makes it a superb
ally for investigating new music, opening the
door to musical adventure. The new Compact
7ES-3 is another masterpiece in the grand
Harbeth tradition.
