All Wharfedale high performance loudspeaker systems are designed to work well
with the majority of good audio equipment. They are also designed to produce
good quality sound at high levels. If you need technical advice or would like to
confirm their suitability please ask your dealer or write to us at the address shown.
We hope that you will enjoy using and listening to your Wharfedale 2090’s.

If you prefer you can wall mount them using suitable rotatable
wall-mounting brackets.
You can mount your 2090s on conventional speaker stands
(see figure 2).

MODELS 2190 AND 3190
WIDE DISPERSION
People who use loudspeakers for public entertainment often put them high up on
walls or near to a ceiling. The result is a dull, unexciting sound with no detail. This
is because the sound absorption of the furnishing and the crowd of people moving
around soaks up the high notes.
Some loudspeaker suppliers get round this problem by using a product with too
much treble, often with painful results. Others try to bounce the sound off the
walls or other reflecting surfaces. They hope that this will make a uniform sound
all over the room. You can not guarantee this. All rooms have different amounts of
sound absorption in different places. You will lose stereo information by spreading
the sound around in this way.
The Wharfedale 2190
and 3190 enables you
to direct the sound to
where the people are.
Conventional
loudspeakers produce
a narrow beam of
sound at high
frequencies. Anyone
moving around in the
room will move in and
out of this beam, and
will find the sound varying in detail. The 2190 and 3190 produces a much wider
area of coverage (figure 1) using techniques pioneered by Wharfedale more than
25 years ago.

CONNECTIONS AND PHASING
Use twin flex with a rib or coloured stripe to identify the positive wire. The current
rating should be 10 amps minimum. The speakers are fitted with spring
connectors to accept bare wire ends that can be inserted into the holes and
clamped. Be careful to trim away any loose strands to avoid shorting the amplifier
output. Connect the wire with the stripe or rib to the red (or +) terminal for both
amplifier and loudspeaker for each channel.
To test the phasing of a stereo pair of loudspeakers switch the amplifier to mono
if possible and play some music, listening to the bass. If you have wired one
speaker ‘out of phase’ the bass will sound weak and ill-defined. Check your
connections and reverse the connections to one speaker only. Refer to figure 4
below when making multiple loudspeaker connections.
WIRING INSTRUCTIONS
There is a special terminal housing on the back of the 2090 loudspeakers in
which the Green terminals are not connected internally. To connect the
loudspeakers as multiple stereo pairs, as shown in figure 4, proceed as follows:
To place adjacent units in parallel use two link-bars G to B and G to R.
To place adjacent units in series use one link bar G to G.
For normal stereo connection use no links.
If you have wired up more than one stereo pair you will need to check the
phasing of each pair separately.
AVOIDING BURN OUT
It is easy to damage loudspeakers by over-driving. This happens when you turn
the volume control up too far, causing distortion. If that happens, turn down the
volume before you do any damage. It is more likely to happen if using an
amplifier with too small a power rating for the combination of room size and
loudspeakers. There are two remedies:
A. Use a bigger amplifier (but with an output not greater than the
power rating of the speakers).
B. Use more speakers (in series-parallel arrangement, keeping the
resultant impedance 4 to 8 ohms).
Note for each amplifier channel:
2 speakers in parallel = 2 ohms - this is too low.
2 speakers in series = 8 ohms
4 speakers in series-parallel = 4 ohms

Connection
The 90 Series loudspeakers are packed with a pair of brackets, see figure (A) .
This steel bracket allows the speaker to be fixed at an angle, either in a vertical or
horizontal position. Mounting the bracket vertically and flush to the wall allows
the speaker to be rotated left to right (see figure 2). Mounting the bracket
horizontally and flush to the wall allows upward and downward tilting of the
speaker (see figure 3).
