General description
and introduction
The DM70 is a precision monitor loudspeaker for domestic and profes-
sional use, built to very high standards.
This loudspeaker, employing the combination of dynamic bass drive
unit in conjunction w i t h an electrostatic transducer for the mid-range
and upper frequencies, is capable of most realistic reproduction of both
speech and music programme material. Because of its low distortion,
wide and balanced frequency response, and relative freedom from
colouration, it will be analytical and may well reveal shortcomings in
programme material and defects in ancillary equipment which an
inferior product w o u l d mask.
We hope that this instruction book will help you to assemble w i t h
ease, and in connecting and placing your loudspeakers, and we have
quite deliberately restricted these instructions to be simple and non-
technical wherever possible.
For an explanation of unpacking and assembling your loudspeakers
(each DM70 system, excluding stands, is packed in t w o cartons) refer
to section 3 of this booklet.
In common with all B & W loudspeaker systems, the DM70 is subjected
to stringent, quality control through every stage of manufacture and
dispatch. Individual frequency response tests are made on every DM70
during manufacture and before dispatch, and we provide you w i t h a
calibration curve w i t h the guarantee registration card.
Provided the instructions are followed, your loudspeaker should give
you many years of completely trouble-free service. In the event of any
query we w o u l d ask you to adopt the following procedure if service
is required:—
England, Scotland & Wales :
Contact the dealer from w h o m you purchased the loudspeakers.
All other Countries :
Contact our distributor for your country—name and address supplied
from our factory if in doubt.
B & W have appointed agents throughout the w o r l d , selected w i t h great
care to give you the best possible service. Should you have any reason
to feel dissatisfied or if any queries arise, we will be pleased to assist
wherever possible.
