Hi Mike, sorry for delay, no i havent specs whats speakers have inside, i have only listened once and the filters works, but nothing like bhi of course.
I think there will be a lot of software that do these work via pc, but i want to try built it
The problem not is my skills in built the circuit, its to understand how to calculate the filters, like you have said me, high, low, bandpass; i have reading some articles, but not are very clear the formulas.
im know that i havent the same skills or studies like an engineer or a person that studied electronics, but i wish to try to do my own filters
