That's hard to do without writing a whole textbook. Of all the books I've read on speaker design, the crossover chapters are always the hardest, because each type of crossover has it's advantages and disadvantages.LimeB wrote:You could do a whole seperate ( or have you already ) on a guide for Non tech typres, to make the cross overs / notch filters and what they should do.
As a general rule, the industry standard is for 2nd order filters (12dB per octave). That's fine, but the industry standard is also to incorporate a light bulb or some other sort of protections device because a fair whack of material still passes through a 2nd order filter. Higher order filters roll off a lot faster, and are therefore much better at offering protection for the tweet. They also sound better IMO. So I use 3rd Order filters (18dB per octave) or 4th order filters (24dB per octave).
Once you decide on what Order filter you'd like to use, there is a wealth of information and calculators available online to help calculate values for your components. I have a really good Excel spreadsheet that consists a gazillion crossover calcs AND wiring diagrams. I paid good money for it so I'm not going to share it around. But there's nothing it's can't do that isn't available online somewhere.
It's incredibly important that you cut your pieces square to start with. Take extra time measuring, and use a "Square" tool often.LimeB wrote:Any tips on squaring the peices when gluing and clamping them together ?
What sort of screws?
And that "Square" tool was never far away when I was gluing the panels together either.
