final best setting.  Your acuteness and ability to perceive very subtle differences will
improve over these days, possibly because you may not have previously had the
opportunity to hear very deep bass in your room. If the bass sounds too prominent,
simply reduce one of the filter controls a notch. If there is a "hole", increase one of
the filter controls until it is filled in.

It is often surprising just how much effect the room is having on the bass response.
Sometimes, even quite small loudspeakers appear to need very low settings of
ABC. If this is the case, accept it and feel pleased that your stereo imaging extends
down so far. It is always better to try and set up for a subtle.  rather than an
overblown effect if possible. However, personal taste is the over-riding factor here. If
it sounds right to your ears, it 

is

 right.

REL sub-woofers are, so far as we know, the only available sub-woofers that
attempt to address the problems of very deep bass reproduction and matching in
any sized room. Until now there has been very little if any attempt by any
loudspeaker manufacturer to help people, particularly those with smaller or
"difficult" rooms, to obtain truly satisfactory loudspeaker/room matching in the bass.

Strata II is designed as a true sub-bass loudspeaker. It is designed to reproduce
those exceptionally deep notes that are felt, rather than heard. This it will attempt to
do at whatever volume you set on the gain control on its panel. If set too high, the
cone will simply run out of movement with the lowest notes, causing a "crack" to be
heard. If this warning is not heeded and the unit is continuously played in this
manner, permanent damage will be done to the driver. This damage is NOT covered
by Warranty. Always try and adjust for a seamless integration with your main
loudspeakers. This will ensure correct settings and minimise the risk of driver
damage.

Strata II is non-critical of positioning. For the loudest and deepest bass, however, it
is best positioned with its back to the wall, or even in a corner.

RUNNING-IN

Care taken over the running-in will be rewarded with many years of pleasurable use.
Both the electronics and the drive units will benefit from an initial period of carefully
controlled use. During this period, permanent damage can be sustained by running
the unit at too high a volume setting. Conversely, by taking a little care over this
initial period (about 12 hours of use), a longer life with a higher potential eventual
performance is assured.

CARE OF YOUR STRATA II

The high quality finish of Strata II is easily cared for by the occasional wipe over with
a damp cloth. Alternatively, a soft bristled brush may be used to sweep off any dust
which faIls on the surface. If objects are placed upon the top of the unit, it is
advisable to use a small mat to protect the surface and to avoid the risk of any
rattles.
Everything about Strata II has been designed and engineered to last a lifetime.
