Eric-1 In Revue Du Son & Du HomeCinema
Eric-1 Anniversary Version
Opera audio has been very successful in making their
amplifier, CD , LP, products , this is the first time
for them to make a speaker system. Eric-1 is one of
the Opera Audio anniversary series. A small bookshelf
model, two ways with elegant natural cherry finish
, a matt aluminum plate covers the front side. It
doesn't look like the other's cheap products "shinny,
unnecessarily complicated , aggressive looks and sounds
cheap", When you see it, you will be loving it,
you are willing to listen to it. It reflexes Opera
's philosophy 'Simple, Humanistic'.
The speaker features a reflex loaded 6.5 " mid
woofer with a 2 inches dust cap indicating the presence
of it's oversized 1.5 inches voice coil and dynamic.
Generally speaking the sound character of one driver
unit is determined by the profile of the cone and
the material. This is the most difficult part of designing
a units. Unfortunately neither system designer nor
most of the driver unit manufacturers knows much about
it. Sometime they have to bless if they could get
a good cone or good unit. The designer of Eric series
has lots of experience both in speaker system and
driver unit designing. So it helps a lot to solve
the problems and to do the optimization. System designing
can even be started from the driver unit level. The
most advanced FEA(Finite Elements Analysis) program
is used to do the optimization during the Eric's development.
Tooling is designed and specially made for this case.
The mid woofer has a very unique look , 6 slots on
the front of the cone with a large pyramid shape dust
cap strengthens the cone structure. Fiber filled cone
materials gives the right damping and also makes it
looks very unique. 1.5" large motor system works
like a V-8 engine to provide enough driving force.
Cooper shortcut ring and a special structure are used
to lower the Inter- Modulation Distortion. As you
know, sometime human ear is more sensitivity to IMD
than THD. So it's important to lower the IMD. Sound
will become more clear and relax.1 inches silk dome
tweeter uses a tiny neodymium magnet to allow it be
placed close to the woofer and to simulate the point
source. CCAW wire is used to gain the right sensitivity.
Ferro fluid technique is to improve the power handling
capability and lower the distortion.
The inner surface is filled with damping material,
3/4" thick MDF and inner bracing is used to quiet
the cabinet. The QB3 bass alignment is achieved to
get best transient response.. 3rd order X-over at
2.6KHz with high grade components (air coil, polypropylene
type capacitor etc) are used for better sound. Electrical
connection is via a big bi-wiring terminal board.
The overall impedance response of the speaker system
is optimized to make it friendly to less powerful
amplifier. You don't need to worry about over loading
and oscillating problems even if you use a small tube
