Environmental aspects - care and maintenance
In the development of loudspeakers we concentrat e
on innovative solutions to problems, and solid, well
thought-out designs, but these are not our only concerns.
We place equal importance on the maintenan-
ce of all German and European safety norms
and standards.
We are able to guarantee that our product s are of th e
highest qu ality, an d meet all our specifica tions in ful l,
because we carry out strict quality chec king of all materi-
als, empl oy painstak ing pro duction methods controlled
by highly qualified staff, and carry out a fully automatic,
computer-controlled final quality control procedure.
At the earliest stage of development we also emphasise
the importance of avoiding environmentally harmful ma-
terials and methods of working.
For example, we avoid the use of materials which are
injurious to health, such as chlorine-based solvents and
CFCs.
We also aim to avoid the use of plastics in general, and
PVC in particular, in the design of our products.
Instead we rely upon metals and other non-hazardous
materials which are easy to recycle.
Electronic sub-assemblies such as valve output stages
are shielded by solid metal housings.
This excludes any possibility of external sources of in-
terference affecting the quality of reproduction. From the
opposite point of view our products’ electro-magnetic
radiation (electro-smog) is reduced to an absolute mini-
mum.
The particle board which we use meets the E1 quality
standard in full. The board i s manufactured without t he
use of chlorides, other halogens and timb er preservative,
and its formaldehyde content is checked at regular inter-
vals by independent monitoring laboratories.
In ecological t erms particle board is e nvironmentally
sound, because its use represents a significant ecologi-
cal use of wood as a renewable raw material.
The sound-absorbent wadding used in our loudspeakers
is made of 100 % polyester fibres, in conjunction with a
binding fibre.
This material has been tested for harmful ingredients to
Eco-Tex Standard 100; the same test is used for
clothing, bedclothes, pillows, mattresses, household
textiles etc.
The wadding we use has passed the „te xtiles tested for
harmful materials“ test and fulfils the currently valid
humane-ecological requirements. It has even success-
fully met the very exacting requirement s of the standard
test for baby clothing.
For loudspeaker transport we have selected a form of
styrofoam packing which g ives excellent protection a nd
is environmentally non-harmful, because:
- Styrofoam is not foamed using CFC-based propellants ,
but with pentane, which is a pure hydro-carbon.
- Styrofoam packaging is 100 % recycla ble; it can be
disposed of, free of charge, at material collection
centres and community recycling points.
- Styrofoam packaging requires for its manufacture 85 %
less raw material and 50 % less energ y than compa-
rable packaging made from other materials.
- Styrofoam packaging consists of up to 98 % air, and
2 % pure hydro-carbon.
- Styrofoam packaging has no harmful effect on groun d
water.
- Styrofoam packag ing helps to reduce freight costs and
transport damage.
Note:
The carton containing the styrofoam packaging h as been
designed specifically for our loudspeakers.
It forms a safe container if you ever need to transport the
speakers, and helps to maintain their resale value.
Care and maintenance:
The surface of the lou dspeaker cabinets should be clea-
ned simply by wiping with a soft, dry cloth.
Never use powerful cleaning agents or solvent cleaners!
If necessary, the front grille can also be clean ed carefully
using a vacuum cleaner.
Please note th at the drive units of some loudspeak er
models are mounted immediately behind the cover, so
don’t press too hard on them with the vacuum cleaner,
otherwise you could damage the delicate loudspeaker
chassis.
Loudspeaker cabinets finished in genuine hardwood
veneers should be set up i n a location away from dire ct
sunshine; real wood changes colour when subjected to
sunlight.
The only permiss ible method of disposing of
this product is to take it to your local collec-
tion centre for electrical waste.
