I recently got my Sierra-1 upgraded by Ascend to Sierra-2. I'm a senior and don't have the manual control I'd need to do it myself. I was surprised to see these paper (magnetic?) covers for the ribbons.
Unfortunately, the print was so tiny, and partially rubbed out, that it wasn't at all clear what to do in removing them. I think I got them off, but then realized I needed to re-attach them to move the speakers up to the top of my entertainment unit. So what I'm not sure of is whether I slid the arrows on pointing the right way--or even if there is a right way. Did I mess up? Is there a right direction in future, when I move (about 3 years from now)?
I'm pretty sure I mostly slid the papers off, but I might have partially pulled up, after moving them part way down across the ribbon. I just was afraid that I was going to stick them into the gap by mistake.
Thanks,

Pegleg,
You are fine. The only thing to be careful of is not to pull straight up from the tweeter to avoid a possible vacuum bubble pulling up on the ribbon element which could potentially bend or tear it. Since you had already slid the paper down exposing the ribbon there should not have been any vacuum to worry about. Hope that makes sense!
Thanks, Mag_Neato. One question I do have: once the paper is removed, I got the impression I should use these if I ever move the speakers (not across the room, but a long move). But since the vacuum no longer exists, would they (papers) just be used to protect the ribbons?
Thanks,
Pegleg
The vacuum is an effect from lifting the magnetic paper up rather than sliding it off and has the potential of forming if the cover is placed back on the tweeter. Reusing the covers for moving the speakers is fine and is not a bad idea at all.
I just installed the upgrade kit. It's a very easy job UNLESS for some inexplicable reason you have one cabinet that accepts the new woofer and another that doesn't, like me. I ended up borrowing a dremel with a barrel sanding attachment and enlarged the opening. Having never used a dremel, I added quite a bit of cosmetic damage in the process. Using the dremel also produces a ton of sawdust which you'd normally want to vacuum out if it weren't for the ribbon being so close by.
So I'd say whatever money I saved on shipping/labor just went out the door with the cosmetic damage I did to one of the cabinets, with no warranty reset. My advice, folks, is if one of the woofers doesn't fit, STOP, and send them in.
FWIW my sierra-1's are gloss espresso from October 2011.
Sorry to hear that. I feel your pain. I added some scuff marks around the woofer openings on my natural cabinets. Not overly noticeable but it was aggravating when it happened. I just recently put the grilles on, having spent the majority of the last 7 years in the shipping box. Can't see the scuffs now!
As for sanding: before starting that procedure it is advisable to remove the tweeter, crossover and insulation. Vacuum/wipe the cabinets when the operation is finished.
Guys -- if you are having any difficulties installing the S2 upgrade kit, please call us before taking the next step. We perform these upgrades nearly every day so we can offer many recommendations
I'm seriously contemplating getting the upgrade kit. I bought my Sierra-1s used from someone else with the NRT upgrade. I'm hoping I don't have to make any modifications. I have the Piano black so would hate to scuff it up.
Do you guys take back the old tweeters, crossover and drivers?
