help mounting Radian CD
Well I just took delivery of some 465PB today and find the mounting studs can only go about one turn deep into the mounting holes. This is trying all studs on all holes. Has anybody else experienced this or are mine defective somehow.

They sit fairly securely but still with a bit of wobble and not completely vertical. Seems strange they dont screw further down into the threaded holes.

That is strange. Not a problem at all on my old Radians.
Could they be the wrong thread pitch?

Thanks for the reply.

Now I am a bit worried, time to phone the States I think.

I agree about the thread
I think they should be 1/4" bolts, If you use 5mm bolts thhey wont go in!

I have Radian 950 pb never had that problem...

Yes, 1/4" 20 (thread pitch)

It does look like 1/4 20, and its what came with the brand new drivers from which is the strange thing.

Radian managed to figure out the problem, luckily. They recently changed from the US system whatever its called (1/4") to metric (M6) and sent me the wrong bolts. No apology from usspeaker and they wont send me the correct ones, told me to go out and buy some, the pricks.
