| | Joined: Apr 2004 Posts: 585 Member | OP  Member Joined: Apr 2004 Posts: 585 | 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? | | | | | Joined: Jan 2005 Posts: 15,287 Likes: 3 Moderator-Vertical, Vodavi, 1A2, Outside Wire | | Moderator-Vertical, Vodavi, 1A2, Outside Wire Joined: Jan 2005 Posts: 15,287 Likes: 3 | You might try MCM Electronics at www.MCMInone.com

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.

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.

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)
