[QUOTE="Max Warasila, post: 211942, member: 3845"] Andy, I'm honestly not sure about this, but I know from creating my subwoofer presets that it can by very tempting to create a preset with a boost below tuning frequency to get more extension. It doesn't actually work super will in my experience, and usually get best results when making up gain at the tuning frequency. That is one explanation of what's going on - trying to make a flatter FR and then using HP to control excursion. It's not the worst way to go. The other option, and where I would actually put my money, is that that peak is for the cold, small signal tuning frequency. I bet that at lower levels the IPD makes more sense, but once the ports choke a little and the VC heats up, I'd put my money on the d&b preset making more sense. I can't wait to hear what Alexander says, though! [/QUOTE]
