Philips Bombardon Ad 5201s/77

[Gijs]

I've got a brand new Philips Bombardon Ad 5201s/77 but I can't find all the specs. I want to build a subwoofer with it cause finding another is very hard.

Vas 300 l ( 247 l)
Fres 29 Hz ( 30 Hz)
Mms 25 g (-)
Qms 10 (6,6)
Q es 0,37 (0,4)
Q ts 0,36 (0,38)
Rdc - (7,5)

These are the only specs i've got (got them from a dutch forum) but I think it would be better to have al the specs so I can build it as good as possible.

Here are some pics of the woofer:

An externally hosted image should be here but it was not working when we last tested it.

I hope somebody can help me out so I can build it as soon as possible.

Dear Gijs

You got alle the specs !
I entered the specs you provide in WinLSD and it draws and calculates perfectly.
Diameter, surface, excursion, power-rating
and impedance are easy to measure.

Would you like me to send you the calculation
for a subwoofer with the Bombardon.

For the non-Dutch. How dows the word bombardon sound to you

Using the second set of parameters in brackets,

With your first set of parameters, not a lot of difference !
though the second set of parameters are better.
Should be obvious reflex loading is better for this driver.

Gijs wanted to build a subwoofer.
So add to the data in the sbapshot
one port/vent of: diameter 0,102 m
and length 0,021 m
