I am looking for some wireless speakers for cold produce storage rooms in a warehouse. What is needed is one transmitter and (5)separate wireless receiver/speakers, with maximum daitance of 300ft. These are for large refridgerated area where customer stores produce, with fairly-thin, insulated aluminum walls. Customer says other companies have this, so the wireless speakers should work through the walls, since they are not steel.
Does anyone know where I might look for these?

Any speaker with much volume is going to need a good power source, batteries in a cold environment sounds like a maintenance nightmare convince them into a real system with wires.

Aluminum will still dampen radio... what do you think the braid/shield of all your Cable TV lines are? Steel and Copper just work better (being denser). Copper works better then steel because it's a better conductor then steel. Atleast this is how it was explained to me way back when. If i'm wrong feel free to correct me

I agree with Merritt and Kumba, get a real intercom. The fact that the coolers are lined with thin aluminum offers no advantage over any other metal and thickness, it will cause problems. I can't even see how something with batteries would be a consideration.

Ask customer for name of establishment that has this 'fabled' system, and then check it out and educate us. I'll bet it turns out to be either 25/70 volt system, or something using the ac power as both a carrier and a power source. John C. (Not Garand)

AC power is available in the fridge rooms. I did not ever consider battery operated units. AC power is a thought, though.
