QUAD 11L Owner's Manual
11L Classis Signature Loudspeakers
WARNING: To reduce the risk of fire or electrical shock, do not expose this
product to rain or moisture. The product must not be exposed to dripping and
splashing and no object filled with liquids - such as a vase of flowers - should be
placed on the product.
No naked flame sources - such as candles - must be placed on the product.
Do not place heavy objects on top of loudspeaker cabinets. If you play them with
the grilles removed be careful to protect the drive units from children and pets.
Do not use makeshift stands. Always fit a manufacturer's approved stand using the
instructions and the fixings provided. Your dealer will advise you.
Do not attempt to dismantle the loudspeaker. There are no user serviceable parts
inside and you will invalidate the warranty.
Site your loudspeakers at least 0.5m away from TV sets and magnetic storage media.
QUAD monitor loudspeakers are true to the classic QUAD tradition of the closest approach to the original sound. No
compromise has been made in quality of materials or workmanship. Although we naturally recommend that these speakers be
partnered with QUAD amplification, they will enhance any quality sound system.
Please read the following notes carefully. They will help you to install your loudspeakers correctly and safely.
Switch off the amplifier and all sources before making connections to your sound system. When you switch on the system or
change sources, set the volume control to minimum and turn up the level gradually.
The position of your volume control is NOT a reliable guide as to the maximum capabilities of your sound system. Playing
the system with extreme settings of volume and tone controls may damage the amplifier and loudspeakers.
Do not connect loudspeaker terminals to the mains supply.
Ensure that your loudspeakers are correctly wired and are in phase.
Do not subject your loudspeakers to excessive cold, heat, or sunlight.
POSITIONING YOUR LOUDSPEAKERS
We recommend that the loudspeakers be placed between two and three metres apart and equidistant from the listening position.
The tweeters should be roughly at ear level to a seated listener. The loudspeakers should be positioned so that they are angled slightly
inward, facing the listener.
The most uncoloured sound will be obtained when the loudspeakers are at least 500 mm from the rear walls and 1 metre from the
side walls. If the loudspeakers are operated closer to the rear walls the bass extension will increase but if they are placed too close to
the walls the bass may boom and become indistinct. If the loudspeakers are placed further away from the walls, the inward angle may
be increased by up to 40%, although this may restrict the width of the optimum listening position.
As personal taste plays a large role, please experiment with different configurations and play a wide range of music before finalising
the position of your loudspeakers.
CONNECTIONS AND TERMINALS
Crossover Network
Quad crossover networks separate the treble and bass networks into two distinct sections, each connected by
a dedicated pair of terminal posts. This enables the treble and bass components to be separately driven for
optimum performance. The upper pair of terminals is connected to the treble network and the lower pair to
the bass network.
As supplied, the treble terminal pair is connected to the bass terminal pair by removable metal straps. These
should be left in place for standard installations.
Choosing and Preparing Cable
Specialist audio cable will usually offer better performance than general purpose 'bell' or 'zip' wire. Audio cable
is polarised, with two cores of different colours, or often, in the case of twin cable, a coloured tracer or ridge
along one wire to indicate polarity.
Choose a cable of suitable diameter - cable that is too thin will limit the dynamics of the sound and may
impair the bass response. Split the twin cores to a depth of about 40mm.
Carefully strip the insulation from each end, leaving about 10mm of bare wire. If the cable is stranded, lightly
twist to gather any loose strands.
Connecting Speaker Terminals
Unscrew the terminal. Thread the bared end of each cable through the hole in the bottom of the terminal
post. Ensure that there are no loose strands which may touch adjacent terminals.
Retighten the terminal securely.
