Joined 2005 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 edit. some pics: http://img259.imageshack.us/my.php?image=im000790hg1.jpg http://img259.imageshack.us/my.php?image=im000795vj7.jpg http://img259.imageshack.us/my.php?image=im000796st6.jpg vinylkid58

Joined 2005 Paid Member Hi Mikko, Those drivers look mint!:bigeyes: 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

Joined 2003 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. http://members.myactv.net/~je2a3/open.htm An externally hosted image should be here but it was not working when we last tested it. M

Joined 2005 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... Simon planet10
