R2SUBZ and R2SUBDF - Installation Guide - Page 8
Although it’s easy to simply reverse the phase of the subwoofer to determine its best phase relationship to the full-range
speaker system, if the best position turns out to be reversed we recommend that you instead reverse the full-range
system(s) so that the subwoofer(s) can remain in a state of positive absolute phase.
R2SUBDF Assembly
The R2SUBDF includes a Direct Firing Mounting Kit that is designed to attach a weather-resistant R2SUB subwoofer
system to the floor, walls, or ceiling in order to take advantage of the surface as an acoustical boundary. Typical
applications include theme parks, sports venues, race tracks, shopping centers, cruise ships, skating rinks, and nightclubs.
Directly firing the R2SUB into an acoustical boundary provides a substantial increase in output level, when compared to
installing the subwoofer in free space.
The kit consists of four stainless steel Mounting Brackets that clamp to each of the four corners of the R2SUB, two stainless
steel Support Struts that provide additional structural integrity when the R2SUB is mounted on a wall or ceiling surface, and
one stainless steel Cable Cover to protect the R2SUB’s attached input cable.
Each of the four Mounting Brackets consists of two parts; the Surface Bracket is first fastened to the mounting surface, then
the Clamp Bracket is attached to the Surface Bracket, thereby securely clamping the R2SUB between the two parts of each
bracket. The Support Struts provide additional support to the R2SUB when it’s mounted on a wall or ceiling. Installation
of the R2SUB on a wall or ceiling should NOT be attempted without the use of the Support Struts.
The following parts are included with the Direct Firing Kit:
Surface Bracket (4)
3/8" Flat Washer (8)
Clamp Bracket (4)
3/8" Lock Washer (8)
Cable Cover (1)
3/8" Hex Nut (8)
Support Struts (2)
Gasket (4)
3/8-16 x 1" Carriage Bolt (8)
Layout Template (1)
Rubber washers, flat washers, lock washers and hex bolts are included on the mounting points of the R2SUB enclosure, and
should be utilized with the Support Struts as needed. No other hardware is provided to install the R2SUB loudspeaker using
the Direct Firing Kit. Such hardware must be supplied by the installer, and should be rated to safely handle the weight load
of the enclosures. The installer is solely responsible for determining if all components that are used to install or suspend the
enclosures are adequately sized and rated, and if the structure they are suspended from is capable of safely supporting the
aggregate weight load.
R2SUBDF Mounting Instructions
1.
First plan the optimum location(s) of the R2SUB(s).
2.
Once you have determined the subwoofer location(s), lay out a square pattern of four holes on 22 1/32” centers
(55.9 cm). See the diagram below. To simplify this operation, a full-size layout template has been provided in the
kit.
