    Hello all. I just completed replacing some surrounds that were incorrect types installed by a previous owner (5/8" roll, over sized surround used, by cutting out a section). My question is about the replaced dust cap(s). These are of the felted (porous) type that allows air passage. Since the AR voice coil formers are the vented type, should the the dust caps be sealed? It has been my experience they should. Thoughts?

    I think you're OK with felt... some places only have certain sizes. So screen or felt works OK....

    Hey Darren,

    We don't mean to be confusing.  We're just enthusiastic.  But, remember, whether you choose film or NPE, or a mix, they'll be an upgrade.  Don't stress too much over it, as there is no wrong choice.

    As to your questions, yes the parallel shunt caps are "second level".  NPE is fine.  The 4.0 and 24uF caps are the series caps.  To me, they deserve "top notch".  Though, as mentioned, electrolytic is fine too.  But, even inexpensive poly's are great.  And they won't ever need to be replaced.

    Good luck.

    P.S.  I literally read and researched for months, when deciding on caps for my AR-90s.  So, you're not alone.

    Passionate...... we'll call it passionate..... I get it!! 

    I did the caps on a pair of JBL CF150's and it was like new speakers... I have done early B and W and seen no difference, I've done some Marantz Imperial 6's and huge change...

    I swear it is all hit and miss as far as a change.... But it does help to do the best you can... then you can go onto other shit as the reasons for shitty sound.... LOL

    thanks,

    Darren
