Touring the R115B
Versatility is the keyword with all SHERMANN Audio
products and the R115B has been designed to maximise
use within a wide variety of system combinations.
This compact, relatively lightweight low frequency workhorse is
supplied with two strategically placed handles to assist loading
or stacking; the cabinet may be used in vertical or horizontal
format .
Four x 80mm rear mounted swivel castors are supplied as
standard whilst an optional castor attachment plate may be fitted
to allow rapid removal of any castor for the odd occasion when
load or stage space becomes a little tight.
A fully recessed, heavy duty 35mm pole mount is also fitted on
the top of the R115B for use with our telescopic extension pole;
these fittings will support a 40kg mid/high cabinet.
Baffle assembly
25mm multi-laminate Scandinavian
birch plywood.

may also be specified in a variety of painted finishes and even
supplied with flying equipment if space restrictions dictate that
LF drive cabinets cannot be floor mounted.
Our expertise in the installation market allows us to offer superb
sounding systems which are highly efficient, cost-effective and
fully compatible with our customer’s requirements.
