      The SPH-135C is an excellent bass-midwoofer. It is crystal clear and very well balanced over the frequency range it is supposed to work on. It isn't very sensitive, so it may seem a bit quiet in comparison to other products. Take that into consideration when designing the crossover network for your speakers. The SPH-135C is top draw.
