Service

The Meridian components have been carefully 
designed to give years of untroubled service. 
There are no user-serviceable parts inside the 
case, nor do the units require any form of 
maintenance.

In the unlikely event that your subwoofer fails 
to function correctly, it should be returned, in 
its original packaging, to your Meridian dealer.

In case of difficulty within the UK or USA 
please contact Meridian Audio Limited or 
Meridian America Inc respectively.

In case of difficulty outside the UK or USA, 
contact the importing agent for the territory. A 
list of Meridian agents abroad is available from 
Meridian.

No responsibility can be accepted for the 
subwoofer whilst in transit to the factory or an 
agent, and customers are therefore advised to 
insure the unit. When seeking service under 
guarantee, proof of the date of purchase will 
be required.

Guarantee

Each unit is guaranteed against defects in 
material and workmanship for two years from 
the date of purchase.

The guarantee is void if the unit has been 
subject to misuse, accident, or negligence, 
or has been tampered with or modified in 
any way without the written authorisation of 
Meridian Audio Limited. 

Note:

 Connecting anything other than the 

correct network lead to the COMMS sockets 
may cause damage to the unit which will not 
be covered by this guarantee.
