She loves me she loves me not!

My Heresy IIIs sound fine with grills, better without...the magnetically attached grills are very easy to remove,  tuck away next to the gear rack, and I put 'em back on every night to keep dust off the drivers...is this sort of thing really difficult for people? Please don't answer as it could upset me.

My speakers don't come with grills so I have nothing to lose so to speak. 😄I also generally prefer the off look.

When I was younger, I liked them off. Perhaps (yes) it was a showoff thing.  Now I like them on and if it was up to me, I would like the speakers to be invisible, as if coming from nowhere!  just beautiful sound originating from an invisible "nowhere".  Interesting how we change with age and maturity... 

It’s your speakers so the risk is yours. 

• We can’t determine your “carefulness” as we are all different
• We can’t determine the “impact” (emotional, financial, replacement) on you if damaged

We can only tell you what we would do aka our own risk level.

 ..   if I keep them off inevitably I will damage them moving them around….

So the question is: 

Do you prefer to leave them off then replace the speakers when damaged (which could be multiple times) or just leave them on?  

Most here would choose save $ and time to replace damaged speakers by choosing the careful path. 

Like a broken record, I suggest you use 'reality' to help you make a decision.

A sound pressure meter, tripod mounted at seated ear level.

A test tone CD with selectable individual frequency bands.

Chart the results 'on' and 'off'. Differences?

Despite differences, Preferences: Visually/Audibly?

inexpensive SPL meters work just fine, even if not calibrated, relative differences +/- is comparative reality.

make sure it has a tripod mount

I have this excellent CD with 29 individual frequencies

There must be others, perhaps I could help you find a copy.
