Hi, I have a query and I hope that you can help me with.
I am starting out on building speakers and have no clue about electronics and would like to learn. To this end I am building my first speaker from a kit. The drivers I decided to get in Australia, but did not want to risk putting together the crossover, which I bought from the USA.
The crossover is put together as per wiring diagram of the speaker kit, except for one difference.
In the tweeter circuit, there is first a resistor going into a capacitor which feeds into a branch. First to an inductor which goes to ground. The second branch goes into another capacitor which feeds into a branch. The first goes into (according to the circuit drawing) an inductor, then into a resistor and then into a capacitor and then goes to ground.
On the circuit board supplied it is not as per the diagram. It is a sequence of capacitor into a resistor into a inductor, which then goes to ground.
I have queried this with the supplier, but would like to get a second opinion.
My question is, does it matter if the sequence is reversed and if so what would be the difference.
Another question is, are components usually mounted with the printing down? I would like to study how components are laid out, and, at a later date, maybe want a look again how it’s done. I don’t even know which way to point a capacitor in a circuit.
I can change the components around, but would really like a second opinion and maybe a short explanation.
The diagram in question is at Zaph|Audio - ZRT - Revelator Tower. I am building the enclosed version of the speakers.
I hope you can help me and clarify things.
Thank you for replying

sorry that the link is not working for you. Can you tell me if it makes a difference to have the components swapped around?

The order of series components is irrelevant. At any given frequency, each component will have a fixed impedance and phase. These values are added together to give the total impedance/phase of the series circuit. Really no different than the fact that 1 + 2 + 3 will equal 6 no matter how you arrange the numbers.
At least I think that's right!
