Good that you checked, Peter. Now what we still can't be sure about without measuring with test tones and a SPL meter is what frequencies the 30-90Hz VTF-2 control actually affects. As Tom Nousaine has shown in his sub tests, the markings on the controls are often off by 20Hz or even more, so it's possible that the 85Hz point might be actually around 70Hz. Whatever, the marking, of course, the important thing is to get the blend that sounds best. Glad to see that you're enjoying your speakers.
