I'm using an analog active crossover on the low pass only.
The high pass is fed from the full range signal straight from the preamp to the power amp: I've created a first order high pass filter inside the power amp by changing the value of the input capacitors. The -3dB corner frequency is 100Hz. It's only purpose is to avoid amplifying unnecessary low frequencies. The power amp feeds the mid-high section of my preamp trough the original 3 way crossover. Passive high-pass at speaker level is 400Hz. Therés a 6 ohms resistor connected to the woofer outputs on the 3 way crossover.
The preamps second output goes trough an analog crossover and feeds the bass amplifier driving the bass horns.
That's where i wanna insert an analog equalizer.
Reason I use this "half passive / half active" bi-amp setup is that I really can't stand the sound of my active crossover in the midrange and high frequencies. Doing like I do gives me maximum transparency and with the low bass filtered from the mid-high amp I don't have any headroom problem.
Problem I'm trying to fix is a peak centered around 125Hz (150?) that's due to the bass horns and most likely worsened by the room acoustics.
That Audio Control Richter scale looks like a great product: I could have crossover and equalizer in the same box, would be ideal!
