[QUOTE="Shonver, post: 50740, member: 34"] But wait a minute! You have a BFD? Why do you need to build an extra filter? Just off the cuff, what I would do is to apply BFD equalisation until it is flat, then add a LR24 high-pass filter. Then play around with that LR24's cut-off frequency. Your scheme is the best implementation, as it includes the room response. Does the BFD have a limiter? Can you set it up to work only in the danger (overexcursion risk) area? If the limiter can kick in only at levels approaching maximum excursion than your woofer can have deep response at moderate levels and reduced/curtailed LF output at high SPL. Just a thought. Never tried it myself. [/QUOTE]
