Re: Subwoofer comparison SRX728 vs Vertec 4883Peter,Let's agree to disagree here. The impedance curve does indeed show a tiny bump from the mass reactance at 300Hz, and this is characteristic of a bandpass. However, the effect is so subtle, and so high in frequency, that it defies the semantic notion of a bandpass as people tend to think of it. You can see a similar effect from the recessing of a driver baffle to allow for excursion.-Phil
