412 CVX Posted February 22, 2012 Report Share Posted February 22, 2012 (edited) Did you use air or iron core inductors for your crossover? Aren't those ment for the "lower" freqs? in a first order 6db/octave crossover, yes. it's used as the low pass filter. but second order 12/db octave crossovers are fairly common in ht systems too. they use a capacitor and inductor for every crossover point. then there's the least common 3rd order 18db/octave 4th order 24db/octave basically the higher the order you get, the sharper the frequency rolls off after the crossover point.

I just realised I missread your post, i read "Did you use iron core inductors for your crossover?" And yes, but iirc the core inductors are less suitable for the higher frequencies, rather than a "normal" one. So for the x-over frequencies of a normal tweeter like that, say around 3k, a regular coreless inductor would be best suited. Or maybe he took it a step further and used inductors wound up with copper foil, those are suposed to be really good. This is just how it's in my brain, so correct me if I'm wrong so i can get myself sorted out. And edit: Sorry for messing up your thread. Are you going to try countersinking that tweeter? It's probably not the easiest thing to do but it would be nice!

412 CVX Posted February 22, 2012 Report Share Posted February 22, 2012 I don't remember if it was like that or the other way around. i know they are less suitable than an air core inductor b/c they can induce distortion. but they're a hell of a lot cheaper. i really want to do an experiment to see just how much difference does it make to the slightly above average joe. it's hard to judge from reading because most of the people who review this stuff have very expensive tastes and VERY picky ears.

bobobass Posted February 22, 2012 Author Report Share Posted February 22, 2012 Did you use air or iron core inductors for your crossover? and what capacitors did you use? I used Dayton poly caps and jazten aircores. i'm considering this for a summer project.
