How do you stop house guest from damaging your speakers?

Over the years I have had many adult guest coming to my house and curious about my speakers though I never mention to them I’m an audiophile. Most of the time they will lean close to the speaker, looking at the driver, maybe occasionally touching the cabinet or knocking on the cabinet. But in other times I’ve had guest touching drivers gently as well and I usually just tell them to stop to prevent them from damaging the driver when I see them doing that.

Yesterday I had a little sit down with a few guests and one of them wanted to play my Blade 2. Out of nowhere, while the music is playing he stood up and walked to the speaker and knocked on the side driver woofer and asked “are these speakers too?” It was probably 3 or 4 consecutive hard knock on the woofer while the woofer is playing, and you guys can already imagine my facial expression. I don’t want to blame the guest as the blade’s woofer doesn’t look like regular woofer and I can’t expect guests to have knowledge of how not to damage speakers, but man, that really hurts when I saw that happen.

I inspected the driver afterward and it seems like all is good and the driver survived. I don’t remember if I heard distortion while the music is playing but to my knowledge this would easily fall into the abuse category for an audiophile.

I’m wondering, do I attach a label to say do not touch on those drivers? Do I tell guests not to physically touch the speakers? 


In the 40 years I have owned moderately high end equipment I have had many people in the room, and have never had one of them touch anything.

If the speakers are so easy to damage that simple touch does so their design is defective. I have horns that are nearing 90 years old and kids can climb in them. I also have new horns that kids can climb on. I have mastiffs and I have no worries anything will be damaged. I actually want guests to touch the large speakers they are very tactile. 


Many of us don't have dedicated listening rooms. We have living rooms or large dens that have to serve the purpose. These rooms are where guests (and their kids) will be when they visit. 

I'd advise to leave speaker grilles on at all times when you either aren't there or have guests over. 

The main issue is of course the turntable, cartridge, and tone arm.  Just too tempting to some. An idea a friend of mine did was to get a nice, stained wood box cover to put over the whole thing when not in use to keep it out of sight. And when most guests come over, play CDs, not albums.  Just not worth the risk whether your turntable costs $600 or $6000. Just the aggravation factor alone would be well, bad. 

Wondering if any of you have had any guests get burned by being clueless enough to touch some KT88 or other tubes on your amps or integrated?  At least once should be enough for most people. 

I suppose we should keep a cage in place, but really, we shouldn't HAVE to. Ugh.
