I'm an Audio Professional and this is a terrible product.
16 June 2014
Summary: I've worked as a networking and audio professional for 4 years now. Since then, I've worked with enough equipment to know what's quality and what is not. Pyle doesn't necessarily have a reputation for high quality products, but I figured for $30, it must be at least decent. Didn't have to be anything spectacular. After an hour of wiring into the car, I was disappointed to produce low volume, low quality audio. Wasn't worth more than $8. Will be returning it very soon.
Summary: I ordered the 8.1 inch speaker and got the smaller one by mistake. I contacted Amazon's customer service and they sent out the correct one right away, so I'm very happy with Amazon's quick response. Obviously you can't expect high fidelity from a horn speaker, but it definitely reproduces voice clearly. I hooked it up to only a 10-watt amp and it is LOUD! If I ever need another PA horn I'm definitely coming back to this one!
Summary: The speakers are quite compact and sturdy. But they are not very loud. Won't work for the crowd control application for my rocket club. But at the price, I probably will not return them. They will be useful at indoor presentations.
