Description
The Harmony One are tall, slim floor standing speakers.
These are single driver, full-range speaker systems, using the
Fostex FE166En drivers. The entire audio spectrum is
reproduced by the single driver. The clarity of sound from
these speakers just has to be heard!
- For a single driver, no crossover is required, and none of the
phase shifts occur that are endemic to crossovers.
- Sound radiates from a single point source, the most
coherent of all. No interference effects occur as between
displaced multiple drivers.
- Single, high efficiency drivers, because of their designed
properties and light cones, give good detail and a large
dynamic range.
The Japanese Fostex drivers are high sensitivity drivers, with
very light paper cones, and powerful magnets. They respond
very quickly and accurately to music signals. Dynamics are
incredible!
The cabinet is a special design to extend the low frequency
response of the system. This is a mass-loaded tapered
quarter wave tube (TQWT), with the driver positioned in the
centre. The low end response is extended considerably,
giving amazing bass from such a short-throw driver.
The cabinets are beautifully finished in real wood veneer. An
option is the use of solid sheesham.

Speaker Grills
The drivers are mounted directly on the front baffle. The low
profile of the driver chassis helps to avoid dispersion
problems in the high frequencies.
A grill is provided, magnetically attached to the driver chassis.
For critical listening, remove the grill, since grills always
produce irregularities in the response.
Connections
Speaker cables should be kept as short as possible, so that
the additional impedance seen by the amplifier is as small as
possible. The best way to do this is to keep the speaker
cables short.
Cables for the left and right channels should be of equal
lengths, and should be placed away from power cables.
Follow the colour code while making connections, to maintain
proper phase between the speakers.
Location
Placement of the speaker system is very dependent on the
listening room, and some experimentation will be necessary.
The room plays an enormous role in the quality of the sound
perceived by the listener. The size, the shape, the ratio of the
respective dimensions, the type of construction of the room;
and the nature and quantity of the furnishings present, all
influence the sound heard by you. Obviously, the location of
the speakers will also be influenced by the normal usage of
the room, and a compromise will be necessary.
In most rooms, the biggest problem is in the low frequency
region. Standing wave resonances are excited by certain low
frequencies in the music and impart a boomy quality to the
sound. This problem can only be minimized by experimenting
with the positions of the speakers and the listener in the
room.
Here are some general guidelines for obtaining the best
sound from your speakers :
- Place the speakers close to the front wall (from the
listener’s perspective), but away from corners. A good starting
point will be to place them about 3 metres apart, 0.5 metres
from the front wall, and atleast 1 metre from the side walls.
- Place the speakers symmetrically in the room.
Furnishings on either side should be similar in nature.
- The direct sound from the speakers to the listener should
be unobstructed.
