    If I didn't have my 910's I would have grabbed them in a heart beat! Yes, would have been a fun project.

    I only changed the 90uf cap on my xovers. I wonder if I need to replace any of the other caps. They sound great though!

    If they sound great, I'd leave them as they are. I'm going to put my originals back in and keep these as backups.

    The ONLY capacitor that should really be changed on the 910's is the 90uF/100uF bi-polar electrolytic. I'm just being honest here, the HUGE metallized polypropylene caps with the loooooong wires that the person with barely a clue installed on Glenn's crossovers in place of these is absolutely ridiculous. All the other metallized polypropylenes shoe horned in are also very unnecessary IMNSHO.

    So I guess that answers my question. I should stick with a bi polar electrolytic for the 90uf / 100 uf cap replacement.
    I'm pretty sure Ricard So recommended to me to usie two bi polar 50uf to replace my 100uf. I wouldn't want to try and quote Richards reasoning for using two half value caps instead of the one. Does any one else have a opinion on this?

    Everything I've read on AK also says just replace the electrolytic, leave the rest. There's also been those that have done complete recaps and stated they sounded noticeably better. Anyway, I bought these for two reasons. One to see if in fact there was a marked improvement, and two, to have a spare set if I ever need them. So the first reason was nullified, I didn't hear any difference. So now I have spares if ever needed.

    2 caps instead of 1= speed.

    2 paralleled capacitors of the same value are:

    - Additive in value

    - Will have the combined ESR value halved

    I don't see how that relates to speed, however. Looking for some insight, here.

    Cheers,

    David

    Not sure either, just an assumption though perhaps shoukd have said that from the gate.
    Some amps I've had use multiple main caps instead of single big ones for speed or some such thing.
    Chapman, in his speaker xovers will do the same thing. Maybe speed is the wrong terminology or maybe 2 caps will indeed act differently than one. I've heard it referred to as speed, at least far as amps go

    Hey gents!

    A pretty nice set of later 910's is on fleabay now, complete with stands.
    Take a look.
    Listening to mine last night, and I'm still blown away by these speakers.

    I noticed the same seller also has a Y shaped cheeto (yes, cheezy puffy snack ) for 543.90
    Chester Cheetah would be proud.
    Of the 24 people watching the un-tested 910's if any are AK'ERS, expect orange thumb prints on your speakers IF they get to you intact. Lol. Sling shot shaped cheeto..lol.

    For them whos close enough to pickup in person, could be a winner.
    Anyone hoping they can ship, not so much.

    Getting these may just push out a bunch of those too many speakers!

    Hey Glenn. Been a while. Just got the LED power meters from the guy in Canada. Comes with the decals but no metal clips so will have to fabricate. Looks pretty cool though. And i don't hear any sound degradation as some have claimed. I didn't get the bi and try-cards. More power is just an easier way to go IMHO.
