Are there any devices specifically for using wireless to powered speakers? I have some outdoor applications that are almost impossible for signal cables. Obviously the problem will be delay - although sometimes I NEED THE DELAY : )

I've used plain old wireless belt packs and strapped the receiver to the top of the powered speaker(s). Also, Lectrosonics makes some wireless devices to send audio to video cameras which are physically much smaller than using regular consumer wireless rigs.

AGI ProDJ on YouTube recently did a video on a Sennheiser system designed for your needs

What type of distance are you trying to get?
I use AT3000 systems all the time for several hundred feet. I guess I haven't found out the max distance because in our application it has always worked.
I also see several companies coming out with speakers designed to recieve a signal from an IPad. Haven't had the opportunity to try these.
For major distance we also use 5 GHZ wi-fi. That is a discussion all in itself.

AT sells the XLRW adaptor cable to connect a console out to a T310b Uni-Pak transmitter and as Dick said, strap the receiver to the powered speaker and that's it.

I think the average distance for the iPad-type stuff is about 30 feet. Unless you're in North Dakota where it's nice and flat with no trees. Effective distance out there approaches infinity........

I would presume the Dick is probably close to right... Its probably basically a bluetooth audio setup, same as bluetooth headphones or the bluetooth in your car... Most consumer level devices like iPads are only going to handle 30 feet or so. There are some bluetooth devices that can do 100ft (I've even seen claims to ones of 100m) but I wouldn't trust them to carry my audio signals reliably... standard RF can be tricky enough sometimes.

Hey now... Every once and a while a Buffalo or a barn get in the way.... And we do have Tree rows!

Funny you should ask. Im doing an event this weekend where I have distributed speakers throughout tents and runways (5k marathon). I use standard IEM systems. I have a rack with all the transmitters which I feed by a Meyer Galileo connected to an Airport Extreme for control and taking an XLR from the DJ for music and Announcements. The venue supplies power to all the locations or at least within 50'. Sennheiser has 1/8" to XLRM that we use and made a few of our own. The powered speakers we use are the JBL PRX line which have 1/4" inputs. On some we use the Sennheiser guitar input cable in reverse. ALWAYS TAKE SPARES OF THE 1/8" TO TS OR XLR. Murphy's law here. If it can break, it will.
Good Luck

Any brand/ model suggestions? i.e.: there are many IEM models - will some provide better frequency response? My application would be live entertainment so obviously we need the best quality we can get
thanks!

One of these:

and as many of these as you need:

Check with Lectrosonics to make sure I linked compatible units.

210 feet claimed range would be in ideal conditions. And they are never, NEVER ideal. Also note that the (mere) 16 channels available cover a range of the mid-600's to the mid-800's. Most of that range (as we know) is reserved for other usage. Operating within the bulk of the claimed range is not legal.

What might be easier to work with, and actually less expensive is:
Transmitter: http://www.lectrosonics.com/IFB/ifbt4.html
Receiver: http://www.lectrosonics.com/Receivers/r400a.html
The advantage with this combination is XLR in, XLR out, no need for adapters to get into the transmitter. Also, these are DC-powered, so you won't need to change batteries, etc. Although the UCR401 receiver above would also meet these requirements, it is meant to be a portable unit, and cost 2x the R400A. The IFBT4 + R400A is what is used most often for line-level signals through the air.
