Hello,
Just wondering if anyone can suggest how deep to make a parallel notch filter (i.e. L,C&R in parallel with each other, in series between crossover and driver driver).
As I understand it, the L&C of an LCR effects the frequencies targeted, and the 'R' of an LCR effects how much the trargeted frequency is allowed to pass, lets say how 'strong' the notch filter is.
This is an LCR with no resistor making a superb job of taming the breakup of two W22s in parallel
This is using a 5.6R resistor
I notice this thread suggests 5.6ohm resisitor, but I don't understand why that value is chosen.
Surely unless the filter is adversley effecting the response of the driver in the range in which it is being used, a very low (zero) resistor value should be used.
Note, I'm using this in the following design which I'm working on... hence the bandpass explaining the lack of low frequency response from the W22s
I'll write a separate thread about these speakers which I'm aiming to use 100% passive filters (two amps needed) just as soon as I'm happy with the crossover. The odd person might recognise them being a slightly more developed version of those mentioned a thread I posted last year here, and incorporating advice offered here
