Rubber inserts around tweeters

[guard52]

Mien feel off, I think they got loose during shipping - do they serve any function other than aesthetics? Gee I hope my woofer didn't get damaged...

After unpacking my Sierras, I took the grills off and found both inserts had come off and were trapped between the speakers and grills. They just press fit back in to place. No harm done but obviously some rough handling must have occurred during shipping. Very musical speakers and a pleasure to listen to.

WOW! You have 7.1 Sierras! You use Sierras as back surrounds!? Please give me a moment as I wipe the drool off my keyboard....

I'd say the finance committee deserves a lifetime appointment!

I second that! Although my "committee", who is very beautiful to boot, actually forced me to upgrade to Sierra fronts, "and stop being so cheap" with myself. Kind of like reverse-WAF.

Hi Dave,

How are they supposed to be attached? Glue, friction fit? This isn't the first time I've read about these falling off during shipping. Since I'm on the verge of possibly ordering Sierras, it has me a bit concerned.

No reason to be concerned.. These are designed to be a friction type fitting and we have received a few reports of them falling out during shipping. UPS can be a bit rough on speakers

If they do fall out, simply pop them back in and there is nothing that can possibly be damaged in the process -- it is really that simple and they will absolutely not fall out in your home. It is a rather snug fitting.

We are experimenting with doing a minor mod on the tweeters in our factory whereby we add a bit of glue to the elastomer waveguide prior to assembly.. Problem is, glues out-gas and the tweeter dome itself can be sensitive to this.

Still, I assure you, it is highly unlikely yours would fall out during shipping and even if they should, just pop them right back in -- simpler then removing and re-installing the grille.

FWIW as a prospective customer, I'd prefer a short note packed with the speakers with a short explanation and some instructions compared to trying to come up with a gluing method.

Dave,

My concern was with potential damage to the tweeter dome caused by the waveguide bouncing around. If you don't feel it's an issue, then I'm fine with it. Especially if glue outgassing is a concern. I can certianly handle popping them back in if it should occur.

On a related note have you ever stuck some of those G-force measuring stickers on a box? Like the one's you see used on Mythbusters. It would be interesting to see just how baddly they get treated. Or maybe, I don't want to know.

In my case, nothing was damaged. I think the insert stayed floating more or less in place for a while.

Hi Doug,

Honestly, it is an extremely rare occurence. I think we have received maybe 7 reports of this in total now, the chance of this happening is less than 2%. I should clarify though, we are working with SEAS in order to find a gluing solution and I fully trust whatever solution they come up (with regard to the potential of the adhesive fumes damaging the dome). Still, your recommendation is a good one with regard to inserting some form of documentation.

This is a SEAS designed tweeter, these guys really know what they are doing and have fully earned my faith. We have yet to receive a report of a damaged tweeter and there are a lot of Sierra-1's out there now

I would actually prefer not to know We have seen some damaged speakers that could bring a man to tears... Wost cases are when a forklift blade goes right through a cabinet...
