ADJUSTMENTS
The G5 ported subwoofer systems need a lowpass filtered signal
to perform best. Thus you have to select the low-pass crossover
function of the amplifier channels that are dedicated to drive your
sub, or activate the headunits DSP based crossover driving the sub
line-out. A filter slope steepness of min 12dB/oct up to 18 or even
24dB/oct is recommended.
Phase optimized connection polarity: The correct and best sounding
polarity for your subwoofer needs to be determined empirically „by
ear“.
This is done by connecting the speaker wire to the plug of the
subwoofer either correctly “in-phase” or with reversed connection
polarity – while the resulting sound needs to be observed sitting on
the drivers seat and with the trunk closed. You can further improve
the phase match of the sub to the satellite speakers, if your amp
features a phase shift control function, or if the headunit deploys a
DSP offering time alignment of sat/sub channels.
Once you have found the correct or better sounding connection
polarity of your sub, you can re-mount the top of the terminal
plug.
The final adjustments now center around the lowpass crossover
frequency point and input level gain of the amp channels driving
the subwoofer. In general, the lowpass crossover frequency should
be set in between 65 to 90 Hz.

BOX LOCATION & GENERAL INFO
The G5 trunk box subwoofer models are designed and acoustically
optimized for deployment in the trunk of hatchback or sedan type
vehicles. The EMPHASER ESP-T2 Terminal provides straightforward
and simple connection of your trunk box subwoofer, or a quick
removal of it when necessary. Accidental reverse polarity connec-
tions are avoided by the special shape of the plug and the receptor
cup, that fit together like a key with a lock.
CONNECTION TO THE AMP
Remove the top part of the speaker plug. Connect the speaker wires
coming from the amp to the terminal binding posts located inside
the main terminal housing. You should strip off 20mm isolation on
the wire end that is connected to the plug. Do not remount the top
part of the plug yet, as the correct connection polarity of the speaker
cable connecting the sub to the amp must be determined first.
