I am no authority on this, but I did a search and there is no reference to using enclosures when installed in a car, such as the door. So I would guess they are meant for an Infinite baffle or very large enclosure.

Hope that helps some...

Do you mean open buffle setup?

Hi,

The short answer is it is more trouble than its worth, car speakers
do not like boxes and the crossover is completely wrong for a box,
and the dispersion of a "top" mounted tweeter.

Large open baffle + subwoofer is the easiest way to use as is.

hi Sreten

can you suggest the baffle dimension? does the tweeter mounted on the top or on the same buffle?

TIA

Hi,

Size is not critical, the bigger it is the lower the subwoofer setting.

Mount the bass/mid at ~ 0.6 of baffle width and the baffle width
down from the top. Mount the tweeter directly above it. The bass/
mid should alo be around 1.6 x the baffle width up from the floor.
So hieght is ~ 2.6 x width.

There are other ways of doing it, but think about your average
door which is ~ 0.7m x 2m, needs 0.2m chopping off, an ~ 0.6m
door would need 0.5m chopping off, between these is ballpark.

hi Sreten

this is the guideline i need. thx alot

i also read some suggest smaller size buffer width. with guideline that the buffer width is less than 2 times the woofer diameter. claim to improve performance. whats your opinion on this?

"Mount the bass/mid at ~ 0.6 of baffle width" does this mean that the driver is mount off axis right?

Hi,

In open baffles baffle width determines bass extension.
The drivers are not centrally mounted, they are offset.
