How would you modify the crossover/eq circuit to work with a “regular” small monitor, instead of the main panel, and use the dipole woofer?
A15 – My answer to FAQ10 also applies to this case. I would imagine that a pair of dipole woofers added, for example, to a pair of B&W DM302 would make for a very natural sounding system. The dipole woofer would add bass output capability to the small monitor with minimal excitation of room modes and boom. It is very likely that the low frequen cy roll-off of the small speaker occurs around 100 Hz or somewhere close to the intended 100 Hz crossover to the dipole woofer. In such case the proposed high-pass filter solution of FAQ10 will not result in the desired 12 dB/oct crossover, because the monitor contributes phase shift and roll-off. This problem can be solved by using the circuit of Fig.9 from Ref.12, which allows correction of the monitor’s frequency response in addition to providing the required high-pass function. The circuit can be constructed using my general topology WM1 printed circuit board. The design for the equalizer proceeds as follows: a – Seal off any ports on the mo
