What to do with this woofer.

[Nordic]

I bought 2 drivers to try and repair an old set, but I am afraid, the drivers do not blend well with the tweeters, and I don't think it is working well with the bass refles boxes it is in now either.

Please help me find a usefull project for these.
I don't even know if these will work for a 2 way, maybe it should go into a 3 way... what do you think.

I also don't know if it is best suited for a sealed or vented box, or remotely what the best volume would be for an enclosure...

Been playing with winisd, but I simply just don't know enough... The woodwork is not a problem, I just have no idea what type or size enclosure to build.

How the hell did you get TVM from Czech republik in CAPE TOWN? There is a forum dedicated to this drivers, but i dont know if you speak czech.anyway, try this http://www.amplion.wz.cz

Sadly no Czech, yep, I understood from the guy I bought it from he had to bring in 100 units...

I will have a look at your link... I guess anyone can understand pictures and diagrammes.

It is a very nice driver I have to say, and it was much cheaper than I expected.

THis one looks nice
