Cards01, I really like my CS24, but these days it collects a lot of dust because I really, really, really like my Shockwave. Being able to have stereo sound and direct the sound in two different directions has been a great feature. If you really want super loud you could always buy a Krakatoa, but it's a pretty big speaker to pack around. If you don't travel much from where you park and where you hunt then it's not really a factor. I usually hike a fair bit so I like a caller I can fit in my day pack, the Krakatoa would be too much for my pack because diameter of the flare, on the speaker, would be too big. Frankly I've never had a calling situation where either the CS24 or the Shockwave left me wishing for anything louder, as they are both pretty stinking loud on full volume.
