david.elsbury Posted November 18, 2009 Share Posted November 18, 2009 Hi allJust a quick one on behalf of someone else. We've got a number of speaker cabinets, both front and horn loaded, that get used outside occasionally and would like to give a little more protection to the paper cones than they currently have. Is there some sort of spray (silicone? waterproofing?) that you can suggest to lightly spray on the cones to avoid them getting waterlogged when used outside?We already tarp the back and side of stacks, which is all good for the cabinets themselves, but just wanted to prevent destroying speakers. Please ask if I need to provide any more detail. CheersDavid Link to comment Share on other sites More sharing options...
Bobbsy Posted November 18, 2009 Share Posted November 18, 2009 Well, I know of a number of people who swear by using "Scotchgard" spray on fabric protector for exactly this purpose. However, let me add the caveat that I've never done it myself and personally would worry that something like this could change the characteristics of the speaker or, if heavy-handed, even do damage.

Jivemaster Posted November 18, 2009 Share Posted November 18, 2009 Most things that you can apply will change the shaps of the cons slightly, so could asily pull the voice coil off centre to the point where it wears itself out on the pole pieces.

bruce Posted November 18, 2009 Share Posted November 18, 2009 Possibly - but I'd suspect that any deformation caused by a light, even spray from something like Scotchgard would be significantly less than the deformation caused by a good soaking with rainwater... I guess you need to balance up the risks... and maybe try it on an expendable piece of kit... Link to comment Share on other sites More sharing options...

Bob Agreed! Works great! (for a while) depends on how long your thinking of leaving them out for. Link to comment Share on other sites More sharing options...
david.elsbury Posted November 19, 2009 Author Share Posted November 19, 2009 We're talking on a gig by gig basis- they'd be covered if left out overnight, but for during shows is more the idea.And they'd be returned to the warehouse between gigs to be dried out if required. Cheers for the ideas so far, feel free to keep em coming Link to comment Share on other sites More sharing options...
StevenW2 Posted November 19, 2009 Share Posted November 19, 2009 Based in Scotland, our speakers regularly get wet, and I anticipate some cabinets getting a thorough soaking this weekend! Whatever method you use to waterproof them or protect them I would also recommend that you get them back into the shed/unit as soon as possible after the gig - leaving them in the truck or van is not a good idea, and leaving them in a flightcase or with a wheel board on is definately not a good idea. Get them into a shed with plenty of ventilation, leave lots of room around the cabinets and dry off the outside with some old towels. If possible put on an oscillating fan to stir up the air. This should help them dry out slowly and evenly. Link to comment Share on other sites More sharing options...
SPTTRIAL Posted November 19, 2009 Share Posted November 19, 2009 When I was working for the uk subs, penetration, vibrators and the like back in the early 80's we had a lot of failures of monitor drivers and the cones collapsing, so we had to come up with a GOB proof monitor, so after hoseing the monitors out for the 5th time, we came up with the solution, using a paint called "dope" this is a lightweight sealer that is used on model airplanes, a couple of coats of this on the cone, and hey presto, we had a waterproof monitor and and could wash them off without destoying the cones. incidently, there are speakers around that are waterproof, try www.onesystems.com they have some decent waterproof speakers and wedges.

I saw the vibrators at toilet (Mr Digbys maybe?) as a punk young man many years ago, and have never heard of them since... Link to comment Share on other sites More sharing options...
tony g Posted November 19, 2009 Share Posted November 19, 2009 I painted a load of Reddifusion PA speakers in a garden centre with diluted polyurethane varnish, a thin coat on the cone, sorted out the damage being caused by wet but as it was only a crumby "british rail" type PA system I couldn't tell you what effect it had on the quality, it was equally bad before and after.
