Electrostatic and Dynamic Speakers and Electronics
The Electrostatics
2805 and 2905 Electrostatic Speakers -
    
The
latest electrostats from Quad, the 2805 and 2905
improve upon their predecessors in a number areas.
The 2805
uses four electrostatic panels, like the 988, and the 2905
has six panels, the same number found in the 989. While the
new models mimic their brethren in many ways, cosmetics isn’t
one of them.
I think we’d all agree, the 988 and 989 aren’t the
most attractive speakers on the planet. Not unsightly mind
you, but clearly in need of some freshening to bring then into
the new millennium. So the challenge for Quad was to improve
the looks and the sound. But how does one go about
improving upon a legend? Carefully, very carefully!
Increasing structural rigidity was a prime
focus. From it’s introduction, lack of structural integrity
was seen as a significant weakness of the ESL-63. A myriad of
solutions have appeared over the years, some moderately
effective, but none
ideal. Arcici introduced a stand which supported the speakers
(ESL-63) vertically, along the sides, and that worked well,
but had distinct
limitations. Quad themselves addressed the issue with the
introduction of the ESL-63 USA Monitor, which featured a more
substantial frame. That helped, but still was not perfect. In
the spirit of DIY, audiophiles conjured up their own
(sometimes very odd)
solutions. I recall a system where a guy used two-by-fours as
braces between the speaker and the back wall! Ugly, yes, maybe
even gruesome, but it did improve performance.
Fast forward to 2006 and let Quad engineers deal
with the issue. They did, and those solutions are realized in
the new speakers. Steel frames that are stiffer still, a more
substantial base and an innovative brace (which seems
particularly effective). At the rear of the
speaker
Quad has installed a tensioned, triangulated strut which runs
from the top of the speaker down to the base. The upgrades
have significantly reduced the tendency of the speaker to rock
back and forth. Further, the heftier pedestal base (which
houses the electronics) adds mass underneath, lowering the
center of gravity.
What’s the sonic payoff? You'll hear significantly
tighter bass, with better control, and a good deal more kick
(the fellows at Quad tell me that in-room response measures
flat to 30Hz!). There is also increased clarity of high
frequency tidbits (string plucks, cymbal shimmer and the
like), compared with the 988 and 989. These are impressive
performance gains.

HiFi News Review
988 and 989 Electrostatic
Speakers -
Are the 988 and 989 a re-birth
of classic, or a poor replica with little more than a passing
resemblance to the original? The ESL-63
has been (and still is) revered for its marvelous ability
to uncover detail, without sounding forced or analytical.
The speaker had a wonderful soundstage and a midrange that
many audiophiles (this one included) feel has never been
surpassed. With such a strong product to follow, I was,
very frankly, afraid of what the new speakers would be like.
There was no reason to
worry, the new speakers are outstanding! Two
models comprise the line, the 988 and 989. Physically,
the 988s are very, very similar to the ESL-63, albeit
a bit sleeker. Internally, the ESL-63 housed an array of
four electrostatic panels, two for the bass, two for the
midrange/treble. The 988, like the 63, also uses
4 panels. The 989s are 30% taller, thanks to an extra
pair of electrostatic panels (for a total of six). The added
radiating area means greater dynamics, volume capability
and bass. Those will no doubt be welcomed words to all who
wished for just a “smidge” more of those qualities from
the ESL-63. The 989s were the first to arrive and
are the focus of this article.
If you’ve heard Quad’s
in past, you’re most likely are a fan. The speaker has a
very musical tonal balance and a unique ability to present
subtle detail in a relaxed fashion. The Quad’s offer detail,
in spades, but the detail never dominates. Some speakers
scream detail, grab you by the throat and force you to listen.
Though short term listening with that type of speaker may
be exciting, the character often proves fatiguing over time.
Quad’s have not one aggressive bone in their body. They
will never hit you over the head and command your attention,
but the music is there, flowing and relaxed. The Quad’s
will draw you in, rather than seek you out.
Tonal balance is on the warm side; the midrange is rich
and liquid. But don’t take that to mean these speakers are
colored, they are not. Listen to a voice recording you know
well and see if the Quad’s don’t involve you with their
sense of naturalness.
The ability to focus
instruments and players on a soundstage is not the forte
of most planar speakers. Quads are different. Many years
ago, Quad’s Peter Walker decided that a point source was
the ideal way for a speaker to radiate sound. Since electrostatics
radiate a planar wave front, Mr. Walker designed a series
of delay lines into the speakers’ electronics, allowing
the speaker to electrically approximate a point source radiation
pattern from a planar diaphragm. Thus, the Quad’s focus a
soundstage more like a good point source speaker than a
typical planar.
As I mentioned at the
outset, an important (maybe critical) character in making
these new designs a success, is that they have that familiar
Quad “sound.” I am here to tell you, they do. Quad has not
thrown out the baby with the bathwater in re-designing this
speaker, but have instead built upon the strengths we all
knew and loved in the ESL-63. If you liked the sound of
the ’63, you’ll be right at home with the 989. The
magic is back, boys!
Memories of times gone
by can be fond. Most audiophiles recall the sound a component
or system we’ve owned in the past and seek to restore that
magic. Quad ESL-63 loudspeakers are indeed the focus of
those memories for many, and you can now happily relive
those moments with the 989.
The Dynamics
The
Quad dynamic speakers live up to the standard set by the
company's electrostatic speakers. The "L" Series speakers
utilize
very high quality components and advanced construction techniques
resulting in speakers that offer outstanding performance at
a very modest price. The
speakers are beautifully finished in a sumptuous high gloss
lacquer over hardwood. Choices include Rosewood, Piano Black
and Bird's Eye Maple.
11L2 Two-way Mini Monitor
I don't know how
they do it. These little
speakers are flat out amazing for the price! Sonic performance,
parts quality and build quality far exceed expectations
for a speaker in this price range.
The cost is just $799.00pr, and
you can choose from real hardwood veneers in a variety of
finishes. A lovely speaker!
