Speaker covers - Safe to leave off?

You're the guy who drunkenly stumbled and destroyed yourself/your hifi aren't you? :D

Leave the covers off OP, they'll sound a little better if you do. Just put them back on if you have kids in the room.
No, I could never destroy my babies :)

I have walked into them during the night though...my fault for awful room layout :D

Oh well. I remember somewhere in one of the numerous 'drunken injuries' threads someone saying they mangled themselves with their Hifi, but I can't remember who it was. I was sure it was a MoH though!
 
Its not the grille material so much as the frame that supports it which can cause some alteration to the sound. It changes (albiet slightly) the baffle profile and hence the edge diffraction effect of the baffle. Very insignificant though, worth using them if other people go in the room, dome tweeters are unfortunately very fragile.
 
depends how you like the sound. you'll probably find that the covers filter out some of the harshness in the treble, for example

Not at all. Speaker covers are acoustically transparent.

Not always.

I have owned Mission 760i, Mission 751, Mission 753, Mission M70 amongst others.

I have found that when I take the grilles off, the treble is clearer/harsher. Putting the grilles on muffle the treble, ever so slightly. Bass is unaffected.

Obviously different grilles/speakers will behave differently.

PS. I'm not a Mission fanboy or anything, it just so happened that whenever I needed a pair of speakers, the Mission speakers would either be award winners or offer the right value for money, at the time.

Once again, try it without looking/knowing, and I bet you can't tell :)
 
If I were to walk into a room, not knowing if they were on/off, then you are right I wouldnt.

However, if you played me a song that I am familiar with, blindfolded and then you either took them on or off and told me this, I would be able to tell you whether you have taken them on or off 100% of the time. I would only be listening out for the treble and I would need to be concentrating hard.
 
In a blind test I was able to tell the difference between the covers being on and off my Mordaunt Short speakers. Just like I was able to tell the difference between bi-wiring and different cabling.

Personally I find it is it the only fair test and the only answer to those non believers who without experience just state "it can't make any difference"

I've tried it on a couple of systems and had to just guess, and it was really just a guess... Maybe the covers didn't make a difference on those, or my ears are crud...

Personally, with my speakers I recon if curtains are drawn in the room is has more effect :)

Not all speakers and their grilles have the same effect. Your speaker grilles might be very transparent.

Another reason might be that to your ears, the effect of the grilles being on/off might be non-existent, even though there might be a difference.
