JBL is one of many brands in the Harman International
Group that benefits
from Harman’s huge research and development department and testing
facilities. You can find JBL audio products being used everywhere from movie
theaters to concert stadiums under their professional line, and also in living
rooms all across the country. They have built a reputation with the public
for creating quality loudspeakers that work well with music or movies and
have developed quite a fan base over the years.
JBL’s Northridge series is
designed around the thought that performance can be delivered at a moderate
price, and the line includes bookshelf speakers, floor-standing speakers,
center channel speakers, and subwoofers. Recently, we reviewed a complete
Northridge system. The
present review focuses on the E90s in a two-channel listening setup.
The E90 floor-standing speakers are a three-way design, featuring dual 8”
bass drivers, a 4” midrange driver, and a ¾” titanium laminate dome tweeter. The
bass drivers cross over at 300 Hz, and the mid driver crosses over at 4 kHz.
The mid and bass drivers use PolyPlas™ technology for their cone material.
This consists of a fiber-based cone that is reinforced with a polymer, which
enhances the rigidity of the cone. The increased rigidity of the cone will act more like a
unified piston and also move the breakup point of the cone to a higher point in the
frequency spectrum (higher than the crossover frequency).
The ported enclosure is made of MDF and is covered with
a wood veneer finish available in black, cherry, or beech. These speakers
are about forty inches tall, weigh 48 pounds, and come with spikes for the
feet. I love the look of real wood, and the rich cherry finish of the review
models just glowed with warmth in my living room. The rear of the speaker
has dual, gold-plated, binding posts, making bi-wiring for the lows and highs
possible. These speakers are rated at 8 ohms nominal and 91 dB sensitivity,
so they are perfect for
medium powered receivers.
I reviewed these speakers entirely in two-channel mode, although they
certainly would work well in a home theater environment. The bass extends
down to 34 Hz, so they can stand by themselves for most musical and movie
listening. If you want that real deep impact though, pair them up with JBL’s
Northridge E150 or E250 series subwoofers, which are in the same price
category. I played these speakers continuously for three hours at a time at
mid-level volumes for about two weeks. After that time, the speakers started
to loosen up and the real warmth of the midrange started to come through. I
found they worked very well placed about six feet apart and toed inwards
I tested these speakers using a Yamaha 5760 receiver, and a Panasonic CP-72
Gould’s 1955 performance of Bach’s Goldberg Variations (Columbia House) is
considered by many to be a landmark performance for classical piano. Gould’s
technique and timing are impeccable and his stylish contributions to the
piece are astounding. The JBL E90s have the performance to bring this piece
to life. For example, the sound has good projection and clarity in all the
tonal ranges and is especially warm in the midrange, which makes listening
that much more relaxing.
Some of the passages in this
recording are incredibly fast and require good definition in the upper
range, which the E90s also deliver eloquently. It is a shame that some of
the great classical performances were recorded under less than ideal
conditions. That doesn’t keep me from enjoying the music though. It was a
pleasure to listen to this older recording on these speakers.
used Steve Reich’s Triple Quartet album to test for imaging. In "Electric
Guitar Phase", four electric guitars play a repeating melodic pattern in
unison with each other and then slightly offset from each other in varying
ways. This creates new melodies and rhythms with each variation. The E90s
created a very nice soundstage with good separation of instruments. I was able to
hear the guitars separate from each other and move within the soundstage as
they panned from left to right and faded in and out with volume. The guitar
notes could also get high in pitch and the E90s always projected the treble
cleanly with a tone that was never shrill, which made listening enjoyable.
new favorite jazz album is The Roy Haynes Trio, with Danilo Perez and
John Patitucci. It features studio and live performances of their tributes
to many of jazz’s most influential musicians. I greatly enjoyed listening to
this album on the E90s. They have the crispness to bring the drums
alive, and their warmth just makes John Pattitucci’s bass sing. Roy Haynes’
drum set was accurately reproduced with crisp authentic cymbals, deep
melodic tom toms, and authoritative kick drum notes.
A piano, bass, and drum
trio has the dynamic range to give any set of speakers a run for their money
and the E90s created a musical experience that had me looking for the
remote’s repeat button.
I down-mixed all surround sound material to two channel stereo mode, which
is the way to go if you don’t have a center, subwoofer, and surrounds. These
work great by themselves for movie viewing with lots of dialogue. The human
voice needs to sound natural, and it certainly does with these speakers. The
E90s also work well by themselves because they are able to project sound
into the whole living room. The sound doesn’t skimp on any of the frequency
ranges, and thus makes it suitable for the music soundtrack or the dynamics
of intense action scenes. These speakers are versatile enough to play movies
on their own, but would really shine with the rest of the setup.
The JBL E90 floor-standing speaker is a great value for a full-range speaker
with good performance. Their neutrality makes them suitable for a wide range
of music and movie listening, and they have good bass extension. They have
excellent tonal range with no skimping on any band, and they are exceptionally
warm in the midrange, which makes for an entirely musical experience. I
would classify these as a workhorse speaker because they are versatile
enough for refined listening, intense action movies, or a house party. They are
definitely a solid performer in this price range.
