May I know the crossover point between the tweeter and the two woofers?

the woofers have no lowpass and it's naturally roll off at around 45-50hz, I believe the M22ti tweeter is being crossed at 2.5khz?

Demasoni: What you are referring to is a high-pass filter because you would only use a low-pass filter at that frequency with a subwoofer.

High-pass literally means that it lets frequencies higher than the specified frequency pass and low-pass means the opposite (lower than specified are allowed through).

Anyways, I do not believe that the woofers have a high-pass filter (as that is kind of pointless since it would interfere with phase and only give you the possible benefit of increasing overall power-handling due to less deep bass being fed into the woofers. Since Axiom speakers are more aimed at fidelity than power output, it'd be highly unlikely that a high-pass filter would be used on the woofers.

Think of it this way: it is analogous to using a low-pass filter on the tweeter to filter out ultra-sonic frequencies. Pointless, right?

I think that the M22ti tweeter has a high-pass filter at 2.7 kHz. I am not 100% sure on that number though.

I would assume that the M22ti mid-woofers have a low-pass filter at around there (~3 kHz), but I've never seen it written down. I know that the M3ti is unique in that it has no low-pass filter so it rolls off naturally at around 2-3 kHz.

PP, welcome. The crossover to the tweeter is at 2.7KHz.

Actually, I'm working on a new crossover for the speakers. Either I'm going to have a new design or I'll use other components with better quality. However, I'm stuck in the schematics. Anyone, have experience in this?

You may want to try asking 2x6spds. He has replaced components in the M3ti crossover if I am not mistaken.

You might also want to try the parts express forum or the madisound forum Both are great places for this type of stuff.

Hi,

The M22ti woofers do have a low-pass filter. It's the M3ti that does not have a low-pass on the woofer. And Axiom does not encourage modifications of the crossovers.
