The main issue isn’t the change in inductance, its core saturation…. Basically in the "real world" air cored inductor don’t saturate (…. they do but at very very high power levels), as soon as you introduce a peace of ferric material into the inductor core space you no-longer have an air cored inductor and at some point you will hit the saturation knee, at this point your inductor is now non-linear and distortion accrues. The smaller the amount of magnetic material in the core the lower the power it which it will saturate so a small screw will saturate at low power were as a large pump of iron will saturate at higher power levels. …. And then we have Eddy currents in the core to consider! |

+1 What I was worried about as well. Just don´t stick any ferrite material in an air core inductor. |

Either under General, or there's a new projects one under plans. Isn't a special build one, but there probably should be!

All set up now. Only thing so far i am struggling with a bit is setting the GAIN on both the subs and mid/tops.
I have tried various different ways which i have read and been told and i find i can have the gain to max without distortion. I have turnt it down to around 2 o clock though as around 2 oclock for the subs was a comfortable level in my garage. And 1 o clock for the mid tops seemed to match. But both could go to max with no distortion. As you can see Min is 7oclock and Max is 5oclock. I would like to know if its ok to have it up higher (even i no distortion) or if anyone has any tips for setting it correctly or any advice on it in general? 🙂👍🏼

The gain is there to match with a wide range of sources, like mixing desks, pré-amps, laptops/iPhone, etc. What is the chain of components you are using as the source now ?
