Hi, I need a little bit of help with my crossover. I have my design and desired parts listed on this
Picture, but I cant find the parts to make it. So my two questions are can anyone point me in the right direction to buy capacitors and inductors? The second one is if I mount them properly, can I mount multiple inductors in series and have the inductance add up to the right value? Will the same go with capacitors? Thanks in advance for any help.
HERE ya go. I recommend using air core inductors of the largest wire gauge you can afford, and metalized poly caps. Yes, you can add inductors or capacitors (although they add in different ways) but do not think you need to hit the calculated values in your image exactly. Inductors in series add, caps in parallel add. Getting within 10% of the calculated value is usually close enough. I generally round values for inductors up (meaning if the computer says I need 55.6mH, I use 56mH) and cap values down (7.35uf becomes 7uf.) Also use non-inductive resistors for tweeter pads, and remember that a calculated crossover may or may not sound exactly the way you want it too, so it is always good to have a box of extra parts laying around and to test and adjust when you build your xover. Building and perfecting passive crossovers can be a very fun hobby or a maddening exercise, depending on how you approach it.
