EMPHASER EBP-T-G5 Anleitung Seite 3

Congratulations on your purchase of this EMPHASER EBP-T G5
bandpass trunk box subwoofer system.
Before you put this subwoofer in your trunk and fire it up, please
read the manual and the operating and adjustment instructions
given in this manual, to obtain best possible sound quality and full
performance.
Your G5 trunk box subwoofer model follows the bandpass enclo-
sure tuning principle, with some special features implemented in
the construction as listed below:
TECHNICAL KEY FEATURES
Loaded with EX-T-G5 woofer
Optimized for high bass output
Cabinet front chamber illuminated by white LEDs
MDF cabinet construction with acrylic glass front panel
Large cross section slot port design
EMPHASER ESP-T2 terminal
BOX PLACEMENT & 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 connections are
avoided by the special shape of the plug and the receptor cup.
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 of each
wire end that is going to be 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.

For safety and legal reasons, it might be prohibited using the logo illumination while operating a car.
Restrictions may apply in certain countries. For making sure to follow all national requirements and not to
distract drivers attention, we recommend connecting the wire for the LED illumination to the interior light of the
trunk compartment.
ADJUSTMENT OF CROSSOVER
The G5 bandpass 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 sub-
woofer either electrically "in-phase" or with reversed connection
polarity – while the resulting sound quality needs to be observed
sitting on the drivers seat and with the trunk closed. You can fur-
ther improve the phase match of the sub to the satellite speakers,
if your amp features a phase shift control function (adjustable
from 0 to 180°), or if the headunit deploys a DSP offering time
alignment of the connected speaker systems.
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.
