Rubber inserts around tweeters

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...

on your Sierras? Yes, it is a waveguide, it is not for aesthetics.

From the Sierra technology webpage:

"Fully integrated slightly elliptical wave guide made from elastomer to reduce diffraction and control off-axis response."

Well, I put them in, and now they sound well beyond what I would have thought possible for a speaker.

Since I never took off the front grilles, I never noticed before. Strange no? Could they have been shaken loose by bass?

Now that I put them back in, will it be OK? Do I need special glue or something?

[curtis]

Never noticed what? Didn't the speakers arrive with the waveguide in place?

You shouldn't need anything special to keep them in place.

I didn't check. I just never took the grilles off. Maybe they were on the verge of falling off and then finally popped completely off?

So... Would bass shake them loose? I was running low freq. test discs to place my speakers and some acoustics treatments, mind you, it wasn't that loud.. I was moving the speakers around... I guess that's the explanation, they they were already partly out, and then finally fell due to bass or even gentle motion.

I checked both woofer and stweeter - they don't look damaged at all, I hope that means something...

I do notice that my sweet spot just got bigger, and that imaging is better than ever before.

I highly doubt bass would shake them loose. The cabinet is extremely inert. They were probably shaken loose during shipping.

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.
