I saw a commercial about this Wirless solution for Rear speakers. The commercial said that it would work with all surround formats. Anyone tried this. I think the Price is around $100.

I work at Best Buy and I can tell you that it is universally compatible with all speakers. However, it is not designed for high current (large, high-end speakers). It is geared more towards "high end" home theater in a box systems. Supposedly, Best Buy teamed up with one of the leaders in wireless technology to make it so it should be acceptable quality. I wouldn't recommend it for a high end system, but if you have a moderate system and need wireless give it a shot.

Seems to be a pretty basic idea... wireless transmitted to a small (probably digital) amplifier for the back speakers. It likely won't provide a whole awful lot of power to the backs but they can probably make due below reference levels. I'd run wire before I considered this but there are times that's not an option and this may be the best alternative.

I would also love to know how this unit performs. Wonder if it suffers from slight delay over wired speakers, as some wireless systems. I have a situation where running wire is not an option, and I hate having wires running across the room.

Another option is the Kenwood RFU-6100. Same concept, more expensive, but at least Kenwood publishes the specs. No specs on the Rocketfish setup makes me think it puts out a couple clean watts at best.

These are geared for at most a very good HTIB. It provides pretty good power for surround speakers in a HTIB, according to what I read. I read of an owner who said the manual reads, '2 x 25W into 4 ohms, RMS'.

kenwood rfu-6100 is 50W x 2

any idea where is the cheapest place to get this? So far I only found $150....

http://www.shoptronics.com/kerfwispamsy.html

but then this is > 3x of what rocketfish is selling....

I'm wondering the impact between RFU-6100 and the rocket fish. I am considering feeding it with the Logitech Z680 speakers which is rated at 62W RMS. Is the rocketfish good enough?

I've used the system on a few installs, and it works well.....supposed to only use it in line of site situations, however I've had good performance with a set up in an adjacent room(open walls) and no problem whatsoever!! If the system buzz's as some have experienced, all you need to do is connect a 100 ohm 1 watt resistor across each channels terminals(L+,L-) and problems solved! Nice little system in situations were hard wire in not a possibility.....

Supposedly, this has been corrected and no longer needs to be done.

Can you use this for front and center speakers? I think wireless sound will be big in the years to come. I, for one, can't wait to get rid of speaker wires.

I can't wait to get rid of electrical cords. Think that'll be big in years to come? I also can't stand paying my electric bill. Hopefully they'll figure out a way to power all this equipment without power.

So this won't work with the Onkyo 705 because the Onkyo puts out 100 watts per channel to the rear speakers?
Thank you.

The receiver will have no part in powering these speakers - they have an internal amp that powers them. You'll still need to plug these into a wall socket (well, hopefully some form of surge protector).

How far are your fronts from the receiver that you'd need wireless? I can understand not liking wires for surrounds, but geez...

I try not to laugh when customers want an all wireless speaker system for all of $500.

The Rocketfish system does work well, but there is a small, probably, 25 millisecond delay on it.

LG makes a similar kit to this. Ive used it with HTIB and also smaller satelites like the mirage nanosat system.

Works relatively well in my experience with it.

I don't think the delay would be a problem, since the receiver should be able to compensate. The Audyssey or similar setup should locate the speakers as a little farther back than they actually are and set the "distance" accordingly.

Thank you.

I am wondering if the high power signal would burn the transmitter.....any idea?

I know Kenwood's RFU-6100 will work, coz they accept the 100W output from the receiver too.

Yes, this is what I was concerned about. I have read that some (a very few) individuals have reported that their Rocketfish did not work and they returned it and the new one did not work either. Given the fact that there are so many people who say it works I am wondering if the receiver does indeed have something to do with it?

Since it's designed to connect to a speaker-level output, I think that it would work with receivers rated at 100 watts per channel. They'd really be limiting their market otherwise.

Looking at this on the website, I don't see much of a point. I mean, I thought each speaker had its own built-in amplifier, and you would plug in each speaker to a wall outlet on the corresponding side of the room. However, this set has a single amplifier to which both speakers must be connected, so you're going to have wires running across the back of the room anyway. Is this really better than just running wires from the receiver? I guess it would depend on the situation.

As I understand it, there are no wires running to the rear of the room. From the Onkyo to the amp/product there is a set of wires, then the receiver located by the rear speakers plugs into a wall outlet as well as connects to your speakers.
Right?

Right, but those two surround speakers have to be connected to the "little" receiver (sort of like being connected to each other). So, you still have wires running across the back of the room, but not from the "big" receiver to the back of the room. I could see where this would be helpful, but I'm not sure why they didn't go all the way and give each speaker its own amplifier.

THD is distortion.
10% is an awful amount..
