Hello,   Do you intend the tonecontrol to move from a highpass of 1064 Hz to a lowpass of 234 Hz I have simulated the output filter and got this responce:   I have also attached the filter chapter from the TI book.   On the net there is also a design tool from Analog: https://tools.analog.com/en/filterwizard/   Bertus sloa088_Active Filter Design Techniques.pdf

I have an NSD, and the only time I tried to drive it, I got stuck inside. My own fault, I was unsupervised. My eldest kid drives it, and she finds it a tight fit. However, I have made the brave decision not to build a Paradigm. Or at least, that's what my wife tells me.   (I'm six foot two, my kid is about five eight, five nine.)

@Dougie C Thank you! It's not perfect, but I'm proud of how it came out. @Tobyskyward Thank you so much! I keep looking at and thinking about making a full figure from it... just don't think I have the space.   Also, thank you to everyone who Liked my post!!

To be honest, I'm highly unlikely to disconnect the shoulders from the skirt now, pretty much negating the "car transportable" feature of this build...!
