Internal Wiring & Box Damping
INCORRECT WIRING OR PHASE WILL
SERIOUSLY DEGRADE PERFORMANCE
INCORRECT WIRING OR PHASE WILL
SERIOUSLY DEGRADE PERFORMANCE
Above two drawings show the suggested way. The internal
wiring as shown and the crossover built into a smaller box of its own (not
drawn to scale). Red is Positive and
Blue is Negative.
Must use battery to make sure
you have gotten the polarity right!
See Battery Check above
As can be seen, there are five pieces of
damping material. These were Wool 60% and Dacron (polyester fibre) 40%.
This has a low density. If you can source this
material, used as insulation bats, but if other types of insulations bats
are used, you may still use above as guide, but some experimentation may be
required. Do not use excessive amount nor material that is too dense.
Also use some suitable glue to hold into place.
The Wool/Dacron bats were cut into the following
shapes/sizes:
2 x 1200mm High, 160mm Wide and 25mm Thick.
Used as Front Damping
1 x 850mm High, 110mm Wide and 75mm Thick. Used
as centre Rear Damping
2 x 1100mm High, 50mm Wide and 75mm Thick. Used
as corner Rear Damping
The above pieces can be fitted after the box assembly
is finished, through the 6.5 inch driver holes.
If denser material is used, then
reduce thickness to less than 75mm in the rear of the box.
