Hi Guys.I'm looking at building the crossover as shown below......
High-pass Crossover Ativo 2KHz – 4ª ordem Butterworth – Automotivo | Toni Eletronica One
I'll be making it as a stereo high and low pass,obviously swapping the resistors and caps over to make a low pass section.What I need to know about this design is....
1.The L7660 voltage convertor,is it manly enough to supply the whole four way circuit by itself,or do I need one per op amp?
2.They specify an LM833 op amp,is this an ok kinda device or could I do better for not a massive amount of money? It'll be used in a reasonably high end install with Phoenix Gold midbass and Image Dynamics horns but not for competition use,so absolute perfect quality isn't that important.
3.Is this actually a Butterworth design? My very basic understanding of such circuits suggests to me that it's actually a Linkwitz-Riley,and although all the designs seem to suggest L-R is preferred for such things,is this actually a good enough design for an in-car 24db/octave crossover?
I have actually e-mailed the designer of the circuit to answer these questions,but as he hasn't got back to me hopefully I can find the answer here.
