there are others on that website as well, just check them out, find something with a decent price. 2 things to make sure u check besides price is 1. make sure its 4 ohm, lots on that site are 8 ohm which will be harder to power, if ur amp says it does 100 watts @4ohm, it will do 50@8ohms. 2. check the frequency response. not sure what ur going to do for crossovers, but make sure the speaker can play to the crossover point your wanting to use
