2090 SERIES • PROFESSIONAL

The WHARFEDALE Wireless Works was established in

1932 by Gilbert Briggs who soon established a reputation

as one of the most innovative loudspeaker engineers of

his generation. His company was at the leading edge of

an exciting new technology which was dedicated to

bringing the pleasure of music and entertainment into

people’s homes. As the technology advanced Wharfedale

gave many music lovers their first taste of High Fidelity,

mounting a series of live sound demonstrations which

excited the audio world and heralded the birth of the

modern hi fi loudspeaker.

Today Wharfedale Systems takes the same

uncompromising approach to the design and

manufacturing of every audio product, using high quality

components and state of the art testing equipment to

ensure consistency and high performance. At Wharfedale

we design and build all of our products and all our drive

units. We control all the variables, so we don’t have to

compromise design goals.

Wharfedale 2090 Series of Professional Sound

Loudspeakers are high quality systems suitable for club

and studio use. They are straightforward to use, reliable in

operation and capable of excellent performance.

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

You can mount your 2090s on conventional speaker stands

(see figure 2).

POSITIONING THE 2090

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).
