We in this hobby are Audio Application Sound Specialists, or AASS‘s for short. We do not design speakers, amps, DACs, cables or turntables. We design audio systems. Therefore, what matters most to us are the basic interface specifications of each component. For example, for a given speaker we need power handling range, frequency response range, efficiency, impedance curve, ported/unported, size, and weight. And finally the looks for those who don’t listen in the dark. For more advanced work the Q factor might be beneficial to know. Nothing in the design/development specs is going to give us much of a clue as to how the speaker sounds or images in our room along with our ancillary equipment and cables. The speaker designer and builder is doing his best to make a product that looks pleasing, plays well with various amps and is reliable all while meeting a price point. I have been known to blow a tweeter or two in my day.
