any thoughts on wireless speakers?..there are kits available for audio quality RF transmission and reception, BUT they arent cheap..anybody have any ideas?
sagarverma
there is a nice an working fm xmitter on

www.sound.westhost.com

build it,use standard fm reciever and fix its response to high power signals only or make yourself one.

alternatively

or good ol discover circuits

the speakers cant be totally wireless,atleast three wires(power);)

You can certainly try.. but ..No One... has yet manged more than low Mid Fi result.. regardless of cost/price
Lotsa Work to replace a couple of wires:-)

what lots of work:confused:

transmitter and reciever.thats it.

effort will be worth it.

Personally, the only half way acceptable solution is to use something like an Airport Express to beam lossless digital to a DAC and Amp right next to the speakers.

Not quite wireless speakers but maybe enough..

Maybe with one Wifi media center per speaker, you can get lossless digital sound

LOL but the cost would deter most of us from doing this :D

there are several cheap studio monitors with spdif input... combine these with some wireless kit, posessing 1MHz bandwidth...

kits are a good idea..and i do know of a couple and have them in the back of my mind..i was hoping to make one BUT it might be a tad too ambitious

buy cheap chinese ir cordless headphones.salvage their IR xmitter unit.....do i have to expand it further:) .reciever also comes along with it.

IR headphone system is great.xmission is lossless(real world conditions apply).

It depends on what you mean by wireless.

Are you planning on using a battery operated amplifier to eliminate all wires? If so, then fidelity isn't much of a concern and there are a lot of ways to go with FM modulators, boom boxes, and mp3 players.

If you're going to allow wire for AC power, that's another thing entirely. You can get pretty hi-fi that way.

Get yourself a couple wireless squeezeboxes ($500/pair) and an amp and speaker for each. Put your CDs on your HDD in .flac lossless compression format. Install slimserver on the PC and "party on, Garth!" You do need to have a wireless router on your computer for this...
You can use a remote control to select music from your CD collection, and a bunch of internet "radio" feeds (they use lossy compression, but it probably isn't any worse than FM radio, and has a lot better S/N).

I have seen older model turtle-beach wireless media players selling pretty cheaply, recently, so instead of using squeezeboxes, you can hunt down the best deal on a wireless media player and get two.

Has anyone yet implememented any (midifi) DIY wireless speakers?

Cheers

Yes I have made wireless DJ sytems using our standard FM transmitter & receiver. If u like FM quality u like this. Anyway I don't anybody can differentiate between good Fm quality and a real Hi-Fi.
I shall post some of mine Wireless speaker models photo 2mrw.

but isn't transmitting on FM limmited to 19khz maximum?

so can you even look at this option .......?

Hi All:

There is another, very simple way...

Most big-box stores sell a wireless A/V Tx/Rx pair that will send your 2-channel audio and 1 composite VIDEO about 100ft. These gizmos sell for around $50. And, they are DIGITAL. Yep! 2.4Ghz public band digital Tx/Rx pair for $50. :D

I bought one about 4 years ago (Sanyo) and use it to send my satellite TV audio signal to my hifi in the next room (for muzak at parties). Fidelity is quite high - way better that a 100mw FM unit, and rock solid (until the wife turns on the Microwave) :xeye:

So, Source -> dTx -> dRx -> powered speakers...

Too simple.

Cheers

I see your point about the 2.4 ghz and the microwave, maybe quad cellphones might give you some interference..

Could be in other parts of the world...
Here in western Canada - so far, no problems with cordless phones, cell phones or ??? - only the dratted microwave oven

Really annoying when I'm trying to record music from the satellite. :cannotbe:

Yes.
At work we built a bunch of wireless effects speaker units in two forms. Both designs use the Sennheiser Evolution G2 systems. The transmitters are the square plug in modules for converntional mics and the receivers are the small packs made for video camera mounting.
One series uses a reciever plugged into the battery powered Meyer UPM speakers.
The other series used a class D car amp driving either Control 1's or Meyer MM-4's.
A show that recently closed used a bunch of them for the sound effects of a flying car (hint,hint) and there are several systems running now in various shows on and off broadway.

fyi
if you get a wireless kit from rat shack you can use it to send a SPDIF stream and then use an SPDIF decoder to decode the raw digital stream.
