Extremely Cheap pair of wireless bi-amped powered monitors.
$55 a pair shipped Blue Aura WS-80i through Amazon 3rd Party Merchant. The discount from the posted $100 price shows on final checkout (before you pay).
NOTE:
Do Not Buy until you read how they work in the linked reviews. They use a proprietary Wi-Fi technology (not Bluetooth, Not compatible with other Wi-Fi speakers) and only accept a signal from the included Transmitter Dongle (which accepts USB and 3.5mm analog stereo sources). Each speaker plugs into AC power..and has no other inputs - they receive from the Dongle Only.
Trusted Reviews Review of the Blue Aura WS-80i and
Tech Kings Review of the WS-80i (this site died in 2014...but the review is more complete.
I have owned a set for a couple of years and they work very well for me, and sound like $2-300 pr. powered monitors. But as mentioned, the system is unique and proprietary.
The vendor "Vanguard Dynamics" is the U.S. distributor. They are trying to off the remaining inventory I expect. I have no interest except its a very nice price on monitors I own and like. They work well for me connected to a Chromecast Audio or Echo Dot through the 3.5mm input. If you have questions on use you can PM me. They establish their own 2.4GHz Wi-Fi network.
