Speaker rolloff? Trying to match my mains and sub.
Can someone eirther explain or point me to a good reference concerning speaker rolloff? Is that frequency, sound, what? I have a decent mid-fi setup, M&K MX150 sub with Vienna Acoustics Haydn mains. This is a combo HT / audio setup. I've matched the dB level outputs using pink noise test tones, but what's all this talk about setting speaker rolloff? I have a Yamaha receiver with a built in 90Hz cross-over. My Vienna's are new, but my previous Boston Acoustics VR M60's seemed to "roll off"?? around 90hz and mostly disappear around 70hz. This seems like a good thing to me based on my cross over settings. What am I missing to truly make these two work together.
