Good answer! I know I generally prefer to have others do the experimentation.

BTW, tweeter "protection" measures and their effect on sound is something I have wondered about in the past. I recall a few speaker reviews (of other brands) that showed measurable differences in level and response with protection removed, but these were, more or less, with screen type tweeter covers.

My own opinion is that removing the "wires" from the Studio2 tweeter would likely change the sound in some small way, but not to a degree that I would be able to hear. The F208's tweeter has a lot of hardware in front of the dome. I doubt it is there as a sound enhancer, but who knows.





Maybe revelman (Mark Glazer) is still reading this thread and will comment. On the other hand, it might be difficult for a Revel employee to endorse owner modifications to product.

I'm very open to being wrong. However you will note that different Revel models have distinctively different "bars" in front of the tweeters. The Revel F32 and F52 as well as the C32 and C52 have completely different "bars" in front of them. The Ultima2 and Performa 3s had likewise different bars.

I'd suggest calling Revel or emailing Revel support directly for a definitive answer. Id tend to think that if it made a significant/audible difference then the "tweeter cover" would have been removeable.

I am with you.

But the question is not whether it would make a difference to remove it or keep it. The question is would it make a positive change to remove it. And I say try it if you want to know. But just like Thxtheater, I highly doubt that Revel stuck them their for anything but a positive effect. Kinda naive for anyone to believe they could better modify the speaker by removing such a portion of the wave guide. Then again, give it a shot. Why not? It is a free country and Salon speakers clearly must be a disposable item.

Yeah why not?
I'm sure that Revel put those "wires" there for no good reason and you, being an acoustic engineer, have wisely concluded that they serve no purpose and in fact inhibit accurate imaging.
Hell it's only a teeny beryllium tweeter back there, it needs room to breathe.
Personally, I'd choose my 12" ChannelLocks and give em a good yank.
Good luck, Gomer and let us know how your before and after measurements stack up.

Being satirical and calling the poster names won't contribute to a discussion, at least not after middle school. You have made no argument, but have only regurgitated a previously stated opinion, also without source.

On the other hand, Sound and Vision calls those wires "a two-wire guard" and likewise for this Perfoma model. They may not speak for Revel, but at least Revel has not disputed this magazine's claim.

So far this is not strong evidence for them being merely protective, but it is still more than the amount of evidence (zero) you have provided to the contrary.

If they were simply guards I would think it would be simpler to make all the guards the same instead of making distinct looking guards for each tweeter model. I'm just guessing though.

I would leave the protection in place, as they (hopefully) were factored into the design and overall performance of the speaker.

Well guys I reached out to Revel. They told me that they had received 15 inquiries into what the bars were for. Okay, just kidding they haven't really received 15 inquiries. But, I was able to confirm that the speakers are designed as a complete system with the bar in place. Removing the bars will simply void your warranty and not give you any good acoustical benefit. So there you have it.

IMO the two wires on those revel tweeters are there to protect the tweeter or just for Aesthetic , but the ones on the revel performa 3 look that they are to enhance the high frequencies.if you remove those on the revel Performa 3 probably the top high frequencies roll off and could affect sound details.


This info may help you.

Thxtheater, thanks for checking with Revel.

I wanted to make sure I had permission to post the email response I got from Harman/Revel support. Now that I got the green light, here it is:

"The protective bars for the tweeters are both for protection and the finished speaker is optimized in terms of sound quality with these in use. All of our transducers are conceived and designed by the Harman Engineering team and built to those specifications.

Unfortunately the removal of the protective bars, and use of unauthorized parts will consequently void any implied warranties or certification of performance. Furthermore, our specifications as well as technical data are extended to the complete finished speaker."

Quick question. My new Revel Studio 2 in black should be here in a few more days. I am noticing where the speakers will be placed gets a considerable amount of sunlight. Is this OK? I don't want the sun to damage the finish or the drivers. I know some speaker companies offer covers. Any suggestions for protecting my speakers?

I'm not an expert enough to know about the UV effects on the finishes of speakers/pianos, etc. However, if you're concerned, I suggest putting a UV glaze on your windows. I've done that and no fading on furniture, rugs—nothing! It's fantastic and works without impeding sunlight and views.

Ok, I came crawling back to apologize for my snarky remark to your post, neutralguy.
My sincere apologies.
Totally unnecessary and unwarranted.
So here is how I should have responded to your query about the wires.
Leave the grills on, listen to the beautiful sounds coming out of your system and forget about the wires.
