What should I do with these Philips Full Ranges?

miccomacho · 19th January 2007, 04:04 PM

Hey everyone.

I have six Philips AD 7080/m4 drivers. I got these for free. All are in perfect condition.

Does anyone have any information about those?

I don't know any parameters. Maybe I should try OB?

Comments...

(My english is quite poor and i'm sure there is some mistakes

)

Thanks

Mikko

Hi Mikko,

Those drivers look mint!

Sorry, I have no info to offer, I have 4 of the smaller version, also free. They sound surprisingly good in OB, but not amazing.
I wouldn't try putting yours in boxes until you have more info, you could try OB first.

Regards,
Jeff

I'd try to get them measured at some point. Also, I think the paper surrounds tend to get brittle over time, so maybe some dope (silicone?) on the surrounds.

I believe they were taken out of some sort of TV or radio console and would therefore be designed for an open/infinite baffle type of use. I'll bet their Qts is somewhere around 1.0.

They were more than probably made for open baffle. I've got some 4" Philips' with accordeon surrounds running in OB (be it 8/side in line array) which puts out quite some bass considering their size and small baffle...

Hi!

I've got a pair of Philips AD3800AM's, wich are 7,5"

Mounted them in a pair of full-size Voigt pipes (2,44 Meters high)

do the same and you'll be supprised of how good these ol' drivers sound

If you want more info on my voigts, the discussion once started at:
Terry Cain's BIB -why does it work and does anyone have those Fostex Craft Handbooks?

cheers!
