Paradigm Reference Active/40 Loudspeakers
Almost everybody I know agrees that active loudspeakers --
loudspeakers with built-in specifically designed-for-the-purpose amplifiers -- make sense.
Yet I know almost nobody who uses them.
Well, no consumers, that is. I know lots of studios that
employ them for mixdown purposes.
You've got to wonder why consumers resist them so. After
all, matching an amplifier to a specific driver/crossover combination makes a lot of
sense. If the speaker nudges 2 ohms at a certain frequency, the designer can build in a
massive amplifier to cope with it -- and if the load remains benign over the speaker's
entire output, it can be matched to a much more modest design.
Plus, it's one thing less to worry about. It means you
don't have to have a rack for an amplifier -- heck, it even eliminates an extra
interconnect and speaker cable. Lordy! These days, you can buy the Paradigm Reference
Active/40s outright for what you save by eliminating a single pair of interconnects. So
why don't people buy 'em?
Well, they're different, and different makes consumers
nervous. And even though reviewers occasionally review them, they seem like an
afterthought. Month after month after month we push power amplifiers -- why believe us, if
every so often, we advocate a system that doesn't need one?
But people are finally starting to accept loudspeaker
systems with self-powered subwoofers -- is it possible that that's the "killer
app" that will turn the tide for active loudspeakers? No, probably not -- audiophiles
have become just too comfortable with the notion that separates mean increased flexibility
to change now.
That's too bad. Too bad for them -- and too bad for
Paradigm -- because the Active/40s are one helluva loudspeaker and one heckuva bargain.
It's a pity that so few audiophiles will actually end up owning them.
Sometimes more is more
The Active/40 is a large (21.5"H by 9"W by
13.25"D) stand-mounted speaker with three drivers -- a 1" pure-aluminum dome
tweeter paired with a 6.5" mica-polymer cone midrange and a 6.5"
filled-polypropylene cone woofer. Paradigm refers to the speaker as a 2 1/2-way design,
meaning that it utilizes a third-order electro-acoustic crossover at 1.5kHz and a
second-order electro-acoustic crossover at 400Hz. These active crossovers, Paradigm says,
allow greater control over frequency and phase response and also eliminate crossover
saturation, a common cause of limited dynamics. All of the drivers are custom-built by
Paradigm and feature massive voice-coils, die-cast heat-sink chassis, and, in the case of
the tweeter, ferrofluid cooling/damping.
My review pair was clad in a handsome rosewood veneer that curves gently away
from the speaker's grille. The speaker's top plate is also curved -- contributing a rather
elegant look that belies the speaker's $2000-per-pair price point. Under the skin, the
cabinets are rigidly cross-braced and reinforced.
The plastic Paradigm logo-plate mounted under the speaker's
grille glows green when the speaker is powered up and turns red when the protection
circuitry is tripped -- or so I'm told. It would take a heartier head-banger than myself
to trip the protection circuitry. Even Waiting for Columbus [Warners 2-3140] at
frat-party level couldn't do it.
The back panel replaces conventional speaker binding posts
with an input/control panel that begins to hint at what a complex system the Active/40 is.
Mounted under a hefty slab of heat-sinking, the panel contains: a high-pass switch
(third-order beginning at 100Hz), in case you wish to use the Active/40 in a bass-managed
system; a low-frequency contour control with a 4dB range; a high-frequency contour control
with a 2dB range; a level control; an RCA line-level input jack; a switch for choosing RCA
or balanced inputs; and a balanced/XLR input jack. There's also a switch for choosing the
"always on" or "auto on/off" function and an IEC AC mains socket.
Extra-long power cables and a pair of 20' RCA cables are also included.
Each Active/40 contains two high-current, fully discrete
power amplifiers -- a 125W amp to power the bass/midrange drivers and a 50W amp for the
tweeter. High-power low-noise toroidal transformers and precision components, including
mil-spec glass/epoxy circuit boards with plated through-holes, are used throughout.
Think about it -- if you were
offered the Active/40 as separates, you'd be getting a pair of 50W monoblocks, a pair of
125W monoblocks, an active crossover system, and a sophisticated speaker system all for
$2000. Sounds like a bargain, don't it?
More to be desired than gold
Actually, they sound incredible. They've got big, muscular
sound that really puts the boot to rock music like almost no other speaker I've heard in
their price range. Dylan's Love and Theft [Columbia CK 85975] is graced by the best
band the man's ever assembled (yes, I do rate it above both the Kooper/Bloomfield Blonde
on Blonde group and possibly even The Band). One of L&T's standout
musicians is drummer David Kemper, who swings with a limber, loosey-goosey version of the
The Paradigms captured this propulsive rock without adding
any boom or bloom. It's a big sound, but they kept it from getting too big. Guitarists
Charlie Sexton and Larry Campbell trade riffs throughout the record, but their individual
sounds were kept distinct and readily identifiable throughout. And Augie Meyers' organ has
never been a more organic part of any band's sound than as it is heard here -- what a
monster player he is. And what a cookin' album. Hope I'm half as vital when I hit
It probably doesn't come as a surprise that the Active/40s
have a big sound -- they're big speakers. They're rated down to 32Hz and they sure sound
like they get there -- maybe even a fewer Hz lower by the time you add room gain.
What surprised me was how delicate they sounded playing
Pierre Bensusan's new all-acoustic Intuité [Favored Nations FN2130]. Bensusan's
playing style -- densely articulated runs punctuated by widely spaced harmonics-heavy
floating notes -- could have been formulated as a speaker torture test. If the crossover
isn't spot-on, or if the cabinet colors the sound, you lose all the magic. Through the
Active/40s, Bensusan's light touch and whimsical compositions survived without an extra
ounce of speaker-induced heaviness.
Nor did they intrude upon Iona Brown's solo excursions in The
Lark Ascending [Argo ZRG 696]. Her viola was so light and so free from boxy sludge and
grunge, it was like listening to liquid sunshine. And what a sweet-sounding, terrifically
The epic sweep of the Reiner/CSO Beethoven 7th Symphony
[JMCXR-0006] was extremely well served. I especially enjoyed the propulsively rocking
cello line in the fourth movement. Talk about boogie!
Inevitably, I wound up listening to many of my favorite
songs -- John Hiatt's new The Tiki Bar is Open [Vanguard 79593], The Delevantes' Postcards
From Along the Way [Capitol 56179], Buddy Miller's Cruel Moon -- with
everything I played, I was impressed by how much information the Paradigms extracted from
my favorite discs and with the phenomenally sophisticated presentation they had.
Soundstages were huge -- both wide and deep. Images were
unwavering. The sound was detailed, yet robust and full-bodied. I really had no

As I listened to more and more music, I was beginning to
sense a slight grain in the upper midrange. It was consistent from source to source and it
was not pronounced, but it colored Emmylou Harris' Anthology [Warner/Rhino R2
76705], robbing it of some of the crystalline sweetness I know the disc to have.
Once I identified this quality, I could hear it with any
source or recording. In side-by-side comparisons with the Dynaudio Contour 1.3 Mk IIs, it
was reasonably obvious -- but when listening to the Paradigms by themselves, it was
noticeable but not all that obvious.
How big a problem is it? Well, it's there, but it's
extremely mild -- it took me quite a bit of listening to identify it. And even once I had,
it was an extremely minor coloration. So minor that changing interconnects or AC cables
might well mitigate it.
In comparison with the Dynaudios, the Paradigms faired
reasonably well. They matched the Contour 1.3 Mk IIs' bass extension and heft quite
nicely, but the Dynaudios had a tonal sweetness and liquidity that the Paradigms simply
couldn't match. This affected extremely low-level detail -- as good as the Paradigms
sounded on their own, they didn't actually extract as richly inhabited a soundstage as the
But think about this. The Dynaudio Contour 1.3 Mk II lists
for $2399, and I was driving it with a $10,000 Krell FPB-300 amplifier connected to the
loudspeakers with $1300 worth of speaker cable. It better sound better. The
Paradigm Active/40 cost $2000, amps included -- no speaker cables need apply.
More and more about less and less
I loved the Active/40. What it does right is capture
the big picture -- music's sweep, drive, and enveloping grandeur. Its single -- to my ears
-- shortcoming was minor and easy for me to adjust to.
And they're cheap! I simply cannot believe that you can buy
this much speaker -- let alone amplifier -- for $2000. It's like buying the speakers and
stealing the amps.
But I'm reluctant to rave too much about the Paradigm
Reference Active/40s. Oh, they deserve it all right. It's just that I know it's a lost
cause. No matter how good they are, no matter how convenient, logical and sensible they
are, I know that audiophiles won't buy 'em, because audiophiles don't buy active
loudspeakers. And non-audiophiles won't buy 'em because non-audiophiles don't buy $2000
Its a great pity, because these speakers are what
it's all about. They're wicked good. They're dirt cheap. They're well built and stunningly
engineered. Too bad most of you will never even think of owning them.
