Summary: I have used to PylePro 3.5" that have 4 ohms output. And compared to this model, I stay with the other ones, they are cheaper and the out impedance es lower which makes it having more output power than this model. This model's output impedance is 8 and it reduces it's sound. I used them with a 200 watt amp, and a 70 volt transformer @ 20 watts. I'll try to upload a video later, so you guys can see/listen to the difference.
Pros: Attractive Design, Easy to Mount, Easy To Set Up, Great Sound Quality
Summary: No problem mounting these to the wall, and the frequency response is adequate for the ambient music in our dining room. One of the terminal posts was stripped, however, necessitating a messy soldering job. There isn't always the time to mail something back or engage in arbitration. Time is money, time is life. It shouldn't be that hard to assemble such a simple product correctly, and inspect it before it goes out the door.
Summary: here in new orleans, we use these speakers when gatherings happen outside in hot and humid conditions. While outdoors, the pair I own right now are not directly exposed to rain and sun. I am buying another pair of these today to put them in the tree out back. The sound is decent.... not breathtaking... but decent. Other reviews are correct.... these need some power to get the volume up. if you are running another set of speakers and forced to use one volume knob...
Summary: I have these out on my deck in Chicago, with no real protection over them - just a tree over one. They seem to have no problem with water, and seem heavy and well made. They sound pretty good, too - they're not as efficient (it takes some oopmh from the amp to get them up to volume), but it's not a big deal since I don't run them simultaneously with my main speakers. I'd definitely recommend them.
