Green Mountain Audio Callisto mounted on sand filled 24" stands. These are bottom ported and sound fabulous with small or large amps. These throw a huge sound stage and play all types of music. Roy Johnson is a genious and great company to work with. You can also home demo these and see for yourself. Good luck!
