Summary: These speakers are very compact in size, especially considering the performance you get from them. There is very deep bass, and crystal clear highs. They. Get. Loud. I got them to go over 100 Decibels without any distorting. The cabinet its constructed from is very sturdy, and after over 10 years of abuse-that's right 10 years, Its still holding up phenomenally. I have my pair hooked up to this receiver: http://goo.gl/iumyUl and it works great.
Summary: I've had these speakers for just about a year now. My first impression unpacking them was "these are heavy!". I liked this because, rightly or wrongly, I associated that with quality materials. I also noticed that they seemed incredibly well sealed which is always good for outdoor equipment. Turns out my first impression was "rightly". :-) The speakers sound really good to my untrained ear; and they hold up incredibly well in heat and humidity.
