FINAL SOUND 300i Loudspeaker Manual vs. 1.3 -US- c FS 2007RJ 20

more powerful and expensive amplifiers with 100-200 watts per channel to cope with very low
impedances.
Although our loudspeakers will work fine with the majority of reasonably priced amplifiers from 35
Watt/channel and up, we also know that our panels will benefit when driven by high powered quality
amps. This knowledge is not limited to the use of electrostatic loudspeakers but is true for any
loudspeaker in the market. Exceptions are the high sensitive loudspeakers which you can drive with
low powered triode and other tube amplifiers. But this belongs to the exclusive domain of audiophile
knowledge and the ultimate dedication towards sound quality. To complete this chapter; room size and
room acoustics have something to do with this equation as well. Bigger rooms need more power,
smaller rooms less. Rooms with lots of absorption from drapes and furniture need more power;
reflective rooms less.
How large are the panels? Is there a special model for a center channel?
The panels come in a range of sizes from 20” tall to 80” tall for front and rear channel use. The center
panels range from 21” to 37” and can only be used in a horizontal position. The center panel includes a
separate vertically aligned tweeter assembly that extends the vertical response of the center channel to
60 degrees off axis.
The Model 90i, 150i, 300i and 400i can be floor standing or wall mounted. The larger panels are
designed primarily as floor-standing loudspeakers. The wall brackets are included in the price for the
90i and 150i and the 300i wall mountable model. Floor stands are included with the larger models. The
panels are sized to match the height of the most popular selling brands of plasma TV between 37” and
60” diagonal.
Where should I place my subwoofer?
Coloration, due to resonance, is strongest at bass frequencies between 20 and 200 Hertz. It’s much
easier to obtain high absorption at higher frequencies. So, the placement of a subwoofer is critical.
Theoretically, the smoothest low-frequency response is obtained when the subwoofer is as close as
possible to the listener’s ears. The received sound from the subwoofer is then dominated by the direct
radiation rather than by room resonances. Practically, the subwoofer should be placed on the base line
between the front panels. That’s also advisable from a phase perspective and if the subwoofer outputs
frequencies higher than 100Hz. You cannot locate frequencies below 100Hertz. If the output is above
100Hz, it’s easy to locate the sound coming from the subwoofer. Then, it’s common wisdom to keep
the sub near the front panels and not along the wall or in the corner.
If you don’t want to put the sub between the front panels and if the output is below 100Hz, the second
best location is nearby the corner of the room, consistent with the acoustic theory that all the room
modes will be excited evenly from this location. But, useful lessons learned from the real world tells us
that the best approach in coping with subwoofers is to use your ears and play around a little bit.
Can I mix and match the Final panels and subwoofers?
Our lines of loudspeakers and subwoofers are modular, scalable and customisable. Basically, we do
have a line for home theatres and a line for professionals and most discriminating audio consumers.
The home theatre packages will bring you five panels in one box and additional subwoofers and
optional floor stands. But, because we’re modular and customisable, nothing stops you to design your
own home theatre configuration, using any combination of Final panels you like. Stereo-systems and
home theatres are also scalable. Depending on your room’s sizes, you can build a system with small
panels, but also head towards a theatre consisting of five large 600 electrostatics. It’s all up to you and
your dealer might give you some good advice. The Final family of electrostatics is arguably the most
flexible offering in the world.
What are the key features of Final electrostatic loudspeakers?
The Inverter technology represents a major breakthrough in electrostatic loudspeaker design.
High resolution and detail: The diaphragm’s combination of low mass together with instant acceleration
and deceleration, will bring a very natural and fast reproduction of the audio signal.
