 Unpacking

Before you begin installation you should ensure that your DSP 

loudspeakers are the correct voltage for your local AC supply. If they are 

not, do not try to install them, and contact your dealer. 

You should not make any connections to the DSP loudspeakers, or to any 

other component in your system, while the AC power supply is connected 

and switched on.

Care when unpacking

Take great care when unpacking or repacking the DSP loudspeakers that 

you do not put undue pressure on the face containing the drive units, as 

they may be damaged if pressed.

Components

Each pair of DSP loudspeakers is supplied with the following components:

 The DSP loudspeakers complete with grilles.

 A hex wrench (3mm) for the drive units.

 Eight screw-in spikes with lock nuts and protectors, together with a 

wrench for fi tting them.

 Head units complete with cups.

 Three knurled screw-in pillars for each head unit to sit on.

 Three plastic spacers per head unit to fi t over the pillars.

 A head connection lead per head unit.

 A top glass plate for each base unit.

 Caution

Meridian Audio has taken every care in the design, assembly, fi nishing and 

packing of this product. The high gloss fi nish on parts of the cabinet is 

achieved by painting up to fi ve coats of polyester lacquer onto the 

plywood, each one hand polished.

Due to the product size and high technology cabinet construction, small 

marks on the lacquer surface may be visible when unpacked. These small 

marks can usually be removed as described in
