Install it on a flat wall surface to ensure a good seal between the bezel and the wall. If you are using two iWS subwoofers in the same room, it is preferable to install the second subwoofer assymetrically. - Page 5 Configurations The basic configuration of the iWS can be expanded. For increased low frequency response and clarity, two iWS enclo- sures may be connected in parallel to the A1 amplifier, which is designed with enough current capability to drive two sub- woofers.

Page 6: Connections
The iWS is designed for use with the A1 amplifier and X1 crossover. As it does not have an internal crossover and requires these components, or it will not function properly. Proper wiring of the subwoofer is essential to good sound. At a mini- mum, 14AWG 2-conductor speaker wire is recommended for runs of 10 feet or less, with heavier special purpose speak- er wire used for longer runs. -

Page 12: Basic Settings For The X1 Crossover
The subwoofer enclosure must be correctly connected to the A1 amplifier and X1 crossover in order to function properly. X1 Design The NHT X1 active crossover is designed to allow convenient front panel adjustment necessary to integrate the iWS sub- woofer with most popular satellites. It also provides unbalanced RCA and balanced XLR inputs and outputs for connec- tion with all types of receivers or separate audio components. -

Master Gain (Front Panel) The Master Gain control allows you to adjust the volume of the subwoofer relative to the other speakers in the system. Use the Master Gain judiciously. A properly calibrated subwoofer blends seamlessly with the Monitors or satellites without calling attention to itself. Here are some general... - Page 14 (as from a movie). Sources with lots of bass output will be the most useful. Adjust the LFE gain control until the bass pro- duced by the subwoofer reaches the desired level. Most users initially set the level of the LFE gain control too high, so be prepared to adjust the control over a long period of time.
- Page 15 Adjust the Low Pass Filter to approximately the same setting as the High Pass Filter as a starting point. Adjust the Low Pass Filter in small increments up or down until the blend between the Evolution Subwoofer and your main speakers is seamless and the subwoofer does not call attention to itself.
