Axiom Home Page Forums General Discussion Hearing Things BrAxiom's been busy!

That's some very interesting feedback from you about your final preference.

The crossover is a bunch of parts in the speaker that act as a steering system for frequencies. Highs go the tweeter and the lows go elsewhere like a mid-woofer and/or a woofer. The crossover can also be used to fix misbehavior of the driver.

The devil is in the hand-off between one driver and another. Another devil is performance of the cross-over under high power.

You can't possibly know if a crossover is good or bad by looking at it. You also can't know by doing math. You have to do tests like Axiom does by spinning the speaker around and taking measurements. You start by doing some math to get the parts close to target and then iterate by measuring and tweaking the parts. When you think you've got it right, you do some listening. And you might need to tweak some more. Sometimes, you might have to build multiple flavors of crossovers, listen to each one and decide what you think your market likes best. That becomes the reference design that goes to production.

Then you get the speaker and phuk things up by swapping a v4 tweeter with a ti.

Rebulx, if you're really interested in crossovers, there's an excellent, free, 840 page book right here.

Like Mojo was sayin the crossovers job is to steer the energy in the frequency range for each speaker to that speakers.
By designing the speaker’s frequency ranges to over lap a bit one can fade one speaker out while fading the next in. Hence the name crossover. Part of the crossover circuit equation are the speakers themselves. Also, the speaker characteristics on reproducing what’s put into them are part of the cross over design.

All the components are designed to work together as a unit… its why swapping a speaker component with different characteristics is not recommended.

Hope that helps

Well, has anyone been exhibiting strange behavior lately or in the past?


For example … whacking M22 wannabees with a gun stock club or perhaps dressing LFRs in lime mankinis

You can't use the behaviors I exhibited in different posts to diagnose my condition in this post.

I'm just say'n ... no diagnostics going on here ...

Just looked at this … it’s excellent if you’re an EE and want some review.
(It’s not even on crossovers but the more general topic of filters)

Mojo is having a laugh … probably couldn’t get though it himself so suggested that you try

Don't let DeSantis see this book. It covers forbidden subjects like frequency transformations, sensitivity and selectivity, and biquads.

Andrew used chapter 11 to build a parametric filter with an analog biquad for the 125, 175 and 350.
