[. . . ] Start by placing the subwoofer close to the center of the front wall, however leaving at least 10 cm (4") of free space in front of the amplifier panel. We recommend a distance of less than 90 cm / 36" to the wall. This position gives increased acoustic loading and SPL due to the proximity of the front wall and floor. Cancellations from the front wall and floor are also avoided. [. . . ] The phase difference between the main speakers and subwoofer at the listening position is dependent upon the position of the subwoofer. To avoid phase differences between the left and right channels and the subwoofer, the subwoofer should be placed close to the center of the front speaker array. Two phase matching switches in the crossover allow compensation for incorrect phase alignment. Four settings are provided between 0° and -270°.
Positioning in the room
The placement of the subwoofer in the room affects the overall frequency response and sound level of the system dramatically, as at low frequencies the effects of the room are strong. Even a slight change in the subwoofer's location can cause a marked difference in the frequency balance and often patient and methodical experimentation
Soffit / Cabinet mounting
If the subwoofer is installed in a cabinet or flush mounted in a cavity inside a wall, sufficient space must be left around it to ensure amplifier cooling and correct functioning of the driver/passive radiator system. The cavity must be at least 10 cm (4") wider and 10 cm (4") deeper and higher than the outer dimensions of the subwoofer. This

variable or fixed, consult the operating manual of your processor. [. . . ] Do not connect two remote controls to the subwoofer at the same time. Remote control overrides the "AUTOSTART" function.
After the phase setting has been completed, return the speaker configuration on the processor to its' original settings.
Warning!
This equipment is capable of delivering sound pressure levels in excess of 85 dB, which may cause permanent hearing damage.
Using multiple subwoofers
The HTS3B and HTS4B are equipped with a "LINK OUT" connector to provide an easy way of coupling two or more subwoofers together in high SPL applications. Connect an XLR cable from the "LINK OUT" connector of the "master" subwoofer to which the decoder is connected, to the XLR input connector of the other, "slave" subwoofer. When two subwoofers connected in this way are positioned close to one another, bass level increases by 6 dB. [. . . ]
