Thinking about picking up a pair of Transducers and can't decide which is a better deal. Those who have experience with both please give your input. I can get a pair of Pro (50W) for $60, or a pair of the 25W ones for $30. Are the Pro's worth the extra $$$ or should I get 4-25W ones for the same price as a pair of the pro's? I wish I could get a Buttkicker but I don't have several hundred dollars or a thousand watts to use on transducers. Thanks in advance!
