Space:
Don’t you wish you had more of it?
If you answered “Yes!” to the above question,
I may have a neat and compact solution for
you. If you have a small to midsize room and a
wife that doesn’t appreciate the rugged good
looks of your favorite power amp parked in the
middle of her flooring of choice, the Jupiter
Audio Europa Active speakers may be just what
the audio-shrink ordered!
The Jupiter Audio Europa speakers are compact
two-way monitors that use Chinese, Silver
Flute drivers and high-quality crossover parts
and internal wiring. The front-ported Europas
can be purchased in either an active or
passive version and either model measures 10
1/2" W x 7 3/4" D x 21 3/8" H. Available
finishes include Black Lacquer or Antique
Cherry for the Europa Active, and Black
Lacquer or Oak Veneer for the Europa Passive.
The cabinets are solid and use real wood
veneers although no grills are available.
Jupiter Audio’s Greg Singh feels that the
speakers are attractive enough as they are and
that the use of grills would only serve to
diminish the performance. Those ‘philes with a
WAF (wife acceptance factor) to consider or
with small children roaming around will need
to ponder whether or not this constitutes an
issue.
The driver compliment includes an 8-inch
wool-filled paper cone woofer with a rubber
surround, a 38mm oxygen-free copper voice
coil, and a die-cast aluminum frame and
former. The Silver Flute tweeter is a 3 1/2" x
6 3/4" ribbon driver using a Kapton film
membrane with copper conductors and a
Neodymium magnet system. System response is
stated as 50Hz-20kHz with no tolerance given.
The
Europa Active, which is the focus of this
review, uses a two-way Hypex amplifier module
that supplies 65 watts to each of the Europa’s
drivers. The Netherlands made amplifier
incorporates an electronic 4th-order Linkwitz-Riley
filter with the crossover frequency set at
2.7kHz via a tidy plug-in crossover module.
Quality parts are in evidence, including a
beefy toroidal transformer and Wima
capacitors. The active Europas can be
configured for either single-ended or balanced
operation, which should be specified when
ordering because you have to remove the
amplifier module to change the internal
pin-strap. This is not at all difficult, but
folks that don’t like to tinker may not be
comfortable performing this short procedure. I
used the review pair only in the single-ended
mode.
It is worth noting that Greg Singh uses
high-quality QED Silver Anniversary cable to
connect the Hypex amplifier to its drivers.
This heavy-gauge cable uses spiraled, quad
bunches of silver-plated, oxygen-free copper
strands, and is silver-soldered directly to
the speaker terminals. Additionally,
absorptive, sound-damping material is used to
pad the amplifier mounting plate. Damping the
mounting plate helps kill any potential
ringing that might be induced by its close
proximity to the speakers.
In addition to being inconspicuously bolted to
the Europa’s rear panel, the Hypex amplifier
modules have a number of control and
convenience features worth mentioning. First
of all, there is a rear panel IEC receptacle
for use with audiophile-approved AC cords. The
amp has a master volume control as well as
separate volume controls for the respective
woofer and tweeter levels. Once the on/off
toggles are set to the “on” position, the
amplifiers have signal-sensing circuitry that
automatically turn them on when a signal is
present and automatically shuts the power off
when there is no signal for 15 to 20 minutes.
From an ease-of-use standpoint, it just
doesn’t get much simpler!
Additionally, there are room equalization pots
that offer plus or minus 3dB of adjustment
below 150Hz and above 6kHz. All the
adjustments can be made with a small
screwdriver and once set to your room and
liking can be largely ignored. My listening
tests were performed with the EQ controls set
flat, and with the master volume, bass, and
treble controls turned almost fully up.
I set up the Europa Actives in my 12’ x 14’
listening room with its vaulted ceiling. They
were supported on heavy-duty, metal, 18-inch
stands supplied by the manufacturer. This
positioned the tweeters close to ear level at
my listening seat. I located the speakers
approximately 3-ft from the front wall and 2
feet in from the side walls, and toed them in
a bit. Homemade Helmholtz resonators and Sonex
panels were employed to improve the imaging
(as with all speakers used in this room).
SignalCable Analog Two interconnects were used
to connect the speakers to my Parasound
P/LD-2000 preamp, and 14-gauge Belden power
cords (nothing too exotic) were used for the
AC power connection.
As it happened, my particular speakers had
been inadvertently wired with the drivers in
opposite polarity (on both the left and right
speakers), but I was able to correct that
mistake by switching the tweeter wires (at the
amps) in the early part of my evaluation. With
the drivers wired in opposite polarity there
was a little more of a suck-out in the
crossover region where the respective driver’s
response overlaps. Switching both drivers to
the same polarity improved the speaker’s
reproduction of brass instruments and piano,
in particular. My listening impressions
(below) are based on the Europa’s sound after
the polarity issue had been corrected.
To The
Listening!
The first things one notices about the Europas
are their sense of intimacy, outstanding
imaging capability, and their prowess on vocal
reproduction. The speaker’s overall character
is warm and musical but without the typical
euphonic embellishments that detract from the
naturalness of lesser designs.
Male
vocals sound natural and correct, without the
artificial chestiness that some speakers
impart. Listening to “Good King Wenceslas”
from the Crash Test Dummies’ Jingle All The
Way (Koch KOC-CD 8439), even with the
predominant male vocal, the backing female
singer’s words could be heard distinctly and
clearly. And on Ray Charles’ Genius Loves
Company (Concord Records/Hear Music
CCD-2248-2), both Ray Charles and Natalie Cole
sounded fantastic singing, “Fever” along to
the beat of that snappy acoustic bass.
On
tracks like “The Nearness of You” from
Branford Marsalis’
Trio Jeepy (Columbia CK 44199), I was
surprised by the Europa’s ability to develop a
sense of space and exactness to the
soundstage. You can virtually walk around
Marsalis’ bass sax and when he turns away from
the microphone it is clearly evident, which
implies the adept portrayal of the related
phase information and micro-dynamic shifts.
Here again, the acoustic bass is tight, right,
and palpable, and the cymbals on the drum kit
shimmer like the real thing.
Without a doubt the Europas are enthralling on
vocals and are very convincing on guitar and
other string instruments. Listening to a
complex musical work such as “Plymouth Rock
Roll” from Brian Wilson’s masterpiece,
Smile (Nonesuch 79846-2), I was struck by
the layering of the voices and instruments
within the soundstage, and also by the sweet
decay of the piano and strings. This provided
a kind of eerie ambiance that captured the
mood of the piece beautifully. Also evident on
Smile was the fact that the weight of the
deepest bass notes was somewhat lacking in
authority, which is to be expected from
speakers of this size.
While I find the Europa’s bass extension
adequate for much of my music collection,
certain of my bass-heavy recordings could
benefit from the addition of a competent
subwoofer. And just coincidentally, Jupiter
Audio makes a very good subwoofer
appropriately dubbed the “Subterfuge A”. As
you may have guessed, the “A” designates the
audiophile version. But the Subterfuge A is
not the subject of this review, nor have I
actually heard it. I am told by Greg Singh
that it works exceedingly well with the
Europas and do not doubt it.
Ascending
into the treble region, the Europa’s Silver
Flute ribbon tweeter acquits itself extremely
well. It is not at all hard or nasty sounding,
but rather smooth, airy, and open. It lends
detail to song lyrics and supplies the upper
overtones of acoustic instruments in a manner
that is easy on the ears, yet on the polite
side of neutral. The Silver Flute tweeter did
a nice job of defining the skins on drum rolls
and of painting the brushes on cymbals. I find
its horizontal dispersion to be excellent and
its vertical dispersion to be much better than
one would expect from such a ribbon design. Of
course the most extended high frequency
reproduction was near the tweeter’s horizontal
axis but when I stood up, the highs did not
disappear as they do in other designs with
similar tweeters. They did roll off slightly,
but it was not a night and day affair by any
means. To me this neat trick was a pleasant
surprise.
Shortfalls
The Europa’s flaws are mainly sins of
omission. As I explained, the lowest octave of
bass is lacking while the mid-bass and upper
bass is quite articulate and rhythmic. I find
that the bass the Europa does produce is
convincing and natural, without overhang or
exaggeration. It does appear to roll off
around 50Hz as the specifications suggest.
Many would not require a subwoofer if the
Europa is used in small to mid-sized rooms
and/or possibly placed a bit closer to the
front wall than the 3-foot distance I used.
As superb as I find the Europas to be on vocal
music, they are not quite as convincing when
portraying brass instruments. This was evident
when playing tracks from my Squirrel Nut
Zippers’ retro-swing CDs, which flaunt the
brass vividly and often. It’s hard to put my
finger on the exact reasons for this other
than to note that in comparison to my VMPS
RM30s or even my Newform Research Module 30
speakers, brasses through the Europas are not
quite as plausible.
Part of the reason my lie in the Europa’s
seeming inability to excel in the reproduction
of macro-dynamic contrasts, and transient
speed. The Europas, while very good for
speakers of their size and price, do not quite
match the incisiveness or dynamic capability
of today’s best speakers. This is not an
egregious shortcoming by any stretch, but it
is an area where I found a bit of room for
improvement.
Summing
Up
The Europa Actives are capable of painting a
very vivid, intimate, and captivating musical
portrait in smallish and mid-sized rooms. They
manage to supply a wealth of detail and
articulation, and yet, are easy on the ears.
They sound fabulous at low listening levels
and can play moderately loud; but, are not for
someone who requires high sound pressure in a
large room.
The Jupiter Audio Europa Active speaker system
will certainly find a niche in the audiophile
marketplace. It’s compact dimensions, ease of
use, flexibility, and potential to reduce the
typical system’s clutter factor are all strong
enticements. The fact that the Europas perform
so extraordinarily well for their size and
price category is the icing on the cake.
Without hesitation, this adroit active speaker
system comes highly recommended by me! Did I
mention the Europas are enchanting on vocals?
