Axiom Home Page Forums General Discussion Technical Questions On crossovers, protection and materials...

Upon reviewing Axiom specs, I notice that there seems to be some info missing:

Crossover network frequency(s)
The presence or lack thereof of overload protection
The surround material for the cones (ie foam, rubber, etc).

I know this is a general question for the whole lineup, but if anybody could point me to an article or knows offhand, etc.

I'm primarily interested in the M22's and the M40's.

Thanks.

Hi Nickwh,

The crossover frequency used in the M22ti is 3.5 kHz. The M40's crossover frequency is 2.2 kHz. It's not so much that the crossover frequencies are "missing" from our specs; it's that the designer believes (and I heartily concur) that while it may be technically interesting, unless you are an engineer, knowing the crossover frequencies is not information on which to base an informed judgment of loudspeaker accuracy or quality.

Overload protection is a function of the output circuitry used in an amplifier or receiver. It's not a factor in loudspeaker design. It is not possible to effectively fuse loudspeakers to protect against transient overload, clipping, and other electrical abuse.

The surround material is a rubber composite.

Regards,

First, thanks for info...

I agree that the crossover frequencies are somewhat unimportant, but one can get caught up in comparison specs.

I have to disagree with you on overload protection. I have 2 pairs of speakers from the Allison AL series and the whole lineup featured "Powershield" overload protection. I have in the past tripped the breaker and it worked, lowering the output until I lowered the volume control. You are right, it won't protect against clipping, but this system seems to work for sustained overdriving of the speakers. You can still blow drivers, so it's probably a moot point.

Thanks,
Nick
