[QUOTE="Peter Morris, post: 139073, member: 652"] Re: New DIY Mid High The crossover is tricky in this case - I think (I may be wrong) from the quick look I had, its a series derived passive crossover and is connected as shown below. If you ignore the low driver in the circuit the VHF has an 18dB crossover, and if you ignore the VHF the HF driver has a 12dB crossover. Soooo I think it will not be a standard filter shape / slope and it will have an ultimate slope of 12 & 18 dB. [/QUOTE]
