The tweeter mounting location inside the car exhibits a direct influence on the front staging and sound
quality of the component system. Depending on the selected mounting location for your tweeters,
the front staging is going to be good or poor. Note that the tweeter level can be attenuated by a
jumper on the crossover’s pcb bord, enabling you to tailor the treble response for different places
of tweeter mounting.
Aim for a tweeter location as unobstructed and as high as possible – recommended places are the
center of the A-pillars, the window triangles or else always as much up and in front as possible.
Attention: The main radiation axis of both tweeters should cross at a virtual point in the center between
passenger and driver’s seat. A direct “on-axis” installation of the tweeters, where they aim or point at
the listener, is not recommended. The result of tweeters angled too much in direction to the listerners
is called “side-biasing” – which can only be compensated with a DSP based time-alignment.
Flat Surface Mounting
Two parts are needed for flat surface mounting. The main tweeter units and the flat aluminum
baseplates.
Mark and drill holes where you want to fix the tweeters. You can use the baseplate ring as a temp
-
late. Three holes need to be drilled, one main hole for the cable routing and two small pilot holes
for fixing the base to the surface. You’ll need 2.5mm and 6mm drill bits and a power drill. After
drilling the holes, mount the flat adapter ring to the surface, using the two self tapping flathead
screws contained in the acessory set. Feed the tweeter wire through the center hole and connect the
tweeter wire to the extension wire. Place the tweeter over the adaptor ring, gently press the tweeter
down and turn it counter-clockwise, to lock it in place.
Flush Mounting
After choosing a mounting location that offers at least 17mm clearance behind the panel, you
need to pre-drill pilot holes for both tweeters. These two holes must be enlarged to 50mm diameter,
using a core drill. The cup adapter part must now be inserted into the cutout, and is fixed with the
mounting bar and two metrical M3 screws contained in the hardware set. Assemble the tweeters
by inserting the tweeter lead wire into the center hole of the adapter, then push the tweeter down
and turn it counter-clockwise, to lock it in place. Finally, attach the tweeter extension wires to the
lead wires on the backside of both tweeters.
