Reference Compact Bass Filter (Oris Horns)

Hi Bill,

I am also interested in knowing how the input impedance of the bass amp effects the frequency response of the filter.

The cascades 6dB filter have influence to each other. The lower the next resistor the lower the Q of the filter and the less steepness behaviour of the filter. In principle the following resistor should be 10 times higher than the one in front to have the least influence. A low impedance amplifier acts as a relative low resistance as shown by the filter and that has negative influence to the filter in front it.

So if I understand this correctly, I see how there is much more bass energy at lower frequencies. It seems like there could more of a "gap" in the bass/horn crossover frequency though. Is this correct?

Yep, that is how it works. More deeper bass and filling the gap by increasing the volume. If there is too much deeper bass (or the gap is too wide) then lower the value to lift the higher bass frequencies.

Ciao,

Bert
