i purchased these speakers two years ago refurbished for $89. i placed one speaker in a room that is 30 x 42 and connected it to a laptop and lcd projector and had an instant home theater. the remote can not turn on the speakers which Outdoor Speakers doesn’t make sense, but the sound is just fine. in my house i have a 5.8 ghz uniden 4 phones system and g wireless router which does not interfere with the signal. if you have a 900 mhz phone or baby monitor nearby it might mess up as with any wireless device operating in the 900 spectrum. you can power the speakers with d size batteries or plug the speakers into an outlet which is the way i used it and have no problems. i saw a teacher in my building use the same speakers which made me decided to by a pair for myself. the speakers are close to the size of a 2 liter bottle and sound like computer speakers. you are not getting bose quality speakers, so don’t expect perfection. they are good computer quality speakers that give you wireless capabilities.
The sound is easy to adjust and the bass is acceptable. I use them for the back yard while having BBQ’s. They work great with our Blue Tooth Cell Phones, I pod – o what ever you can hook into the holder. I would recommend these to anyone who is looking for a set of out door speakers. Easy set up. Anyone can set them up. We utilize the external power source for these. Although batteries can be put in but that seems rather expensive.
