Since the above was posted to the group I assume the poster will have the
courtesy to also be reading this, and able to respond...

I have been reading the issue advertised in the posting. On page 31 it
contains a line from a loudspeaker designer to the effect that:

"This is because when you bolt the driver to an MDF baffle, you cannot go
past three Newton-pounds torque without damaging it..."

I am puzzled for various reasons.

1) 'Newton-pounds' don't seem to be either SI units or Imperial ones.

2) 'Newton-pounds' strikes me as not having the correct dimensions for a
torque - although given (1) it is hard to be sure. :-)

3) I'd have thought that damage would result from excess *pressure* or
shear or bending forces. The effect of applying torque to a bolt would
presumably depend on a number of other factors like the size and shape of
the bolt-head face. (Also the details of the item being bolted down.)

So can someone from HF+ explain what was meant? Was it a typo? If so, what
should it have said? Or is it literally a transcript og what the person was
saying "In his own words..." as the header of the box states? if so, what
was he meaning?

Slainte,

Jim

Jim, firstly sorry for the very late reply.
Can I suggest you put your query as a letter to the editor - theres an
email link on the website (letter page).
I have no hi-fi expertise myself (apart from knowing what I like in my
own set up) but the editor and contributors have it in spades.
Hi-fi+ Webmaster
