I've just acquired some new speakers. They've got unusual-looking dust caps - think they're floating dust caps, as described here http://www.300guitars.com/articles/dust-caps-the-deal-on-dust-caps-by-anthony-lucas/ - and there's a small scrape/scratch on one of them.

There's pics here http://www.flickr.com/photos/96845896@N03/ Two questions, really - doesn't seem like a likely cause of problems, but unusual-looking things so I don't know if I'm right? Also, does having this type of cap make them easier/harder to change if it does come to that?

Thanks!

That is not the dust cap. That is the end of the pole piece. Lots of manufacturers don't bother with a cap.

Thanks, and doh - I had wondered if it was the end of the pole piece, but thought it looked a bit dust-cap-like.

Predictable next question, then - would a scratch on the end of the pole piece be a likely problem?

Nope, not at all. Wont make any difference apart from your OCD :D

Thanks! So, if I've understood things right, it's the speaker cone that vibrates (making nice music :) ) while the pole piece is part of the magnetic assembly that generates the force needed for this?

I'll try to watch the OCD ;)

And to dissipate heat in the coil when in use.

Thanks - learned something new about speakers, anyway! Sensitivity in the low 80s, and 4ohm - so suspect they may have a bit of heat to dissipate?

Now, after all that I just need to make sure I don't drop them next time I'm moving them round :)

With spec's like that, Just make sure your amp is up to the task ;-)

I from experience/having forked out much in many places advise you suitably-safely to maximise your perception of your stuff/enjoy suitably.

Sometimes stuff that looks naff sounds fine.

I confess that I need my stuff to look brill to sound ace.
