I needed a heavier duty speaker for some free dj'ing gigs. I put these on speaker stands to get them off the ground, and it really helps the bass. Light and easy to mount, with lots of speaker connection options. I use banana plug at the ends of my heavy guage speaker wire. They're 25 ft compared to the 15 foot speakon cables that came with my speaker stand package. I only use a home theater receiver which also has banana connectors, but if I ever get a pro level amplifier the speakers will be able to handle anything (speakon, 1/4 phone, bare wire, or banana plugs).
I recently provided audio and visual for a ski movie. I used these speakers on MONO with a separate powered sub. To augment the vocals, I ran a separate output to a powered speaker through a small mono crossover device. I set that speaker to about 250 hertz cutoff, while the pyles were running at 100 hertz. The sub handled anything below 100, with my receiver doing the splitting between the sub and the pyles. Sounded excellent.
