Looks like it happened on Sunday so the Polk Audio webservers got kind of a reprieve. It's a shame though because most of the people commenting obviously have no clue about audio at all.
BTW, just so everyone here knows, current wireless standards do not have teh ability to support the bandwidth needed to transmit a full 20Hz-20kHz signal across a WiFi link. The next generation stuff coming out will but we are still a few months away from that.

I always wondered what a ping sounds like.

CD audio is 44.1 KHz @ 16 bits. 802.11b has more than enough bandwidth, 802.11g is has even more.So what if those speakers are as big as a Subaru and cost twice as much? You'll never have to trade these babies in and when you die, they can bury you in them.
And, if you can't afford them, F***ing FINANCE them! -
I'm not sure you understand what is involved here.
Sure, a CD may only be recorded at those standards but we aren't talking about a single bit stream of CD audio. If you have a stereo rig with these speakers, you are sending two streams of audio. On top of that, to get the kind of performance one would need to have these sound acceptable, you need to stream the audio. The way that the packets would be handled to do so would cut your bandwidth by at least 30%. You might be able to get some of that back if you compress it but then you get losses in signal quality. Add to all of that the error checking in the signal, the bit checking on the stream itself and encryption on the wireless network. That is just the obvious stuff. There is not enough bandwidth in current wireless technology to support a full, uncompressed 20Hz-20kHz audio signal. Especially not multiple signals with multiple paths.Expert Moron Extraordinaire

Along with jstas said, the packets allow wireless to operate in a computer network as delays are made up at other times and once the file is complete, it is re-assembled. Since the audio signal would be realtime with no openings for delay (without greatly increasing the cost of the recieving unit), you would need a huge bandwidth to ensure acceptable performance.
The average rate on wireless is fine, the problem is it can not be considered constant.There is no genuine justice in any scheme of feeding and coddling the loafer whose only ponderable energies are devoted wholly to reproduction. Nine-tenths of the rights he bellows for are really privileges and he does nothing to deserve them. We not only acquired a vast population of morons, we have inculcated all morons, old or young, with the doctrine that the decent and industrious people of the country are bound to support them for all time.-Menkin
