Axiom Home Page Forums General Discussion Technical Questions Tweeter differences

Is there any major tonal difference between the regular titanium tweeter and the "hybrid" tweeter used in some models?

yes,

the hybrid uses a half inch voice coil, whereas the others use a regular 1 inch voice coil. The hybrid tweeters are less open, less airy, and, of course, not as detailed and clear.

Why would one use a half inch voice coil in a one inch tweeter?

Hi,

The short answer to using a half-inch voice coil in a 1-inch tweeter is cost.

Using a 1-inch voice coil means a larger magnet and greater power-handling capability. The magnet/voice-coil assembly is the speaker's motor--a reciprocating electro-magnetic motor--and the larger voice coil yields better high-level power handling with less distortion and improved heat dissipation. But it's also more expensive, which is why it's found on more expensive models in the Axiom lineup.

Huh! I wonder how many out there have half inchers.

My brother and I both have m60ti. My tweeters are incredibly cleaner than his. We’ve always puzzled about why that is. I mean there is a ton of factors, source , room, power plant etc. But at high volume his break up way easier and messier. Maybe he’s got half inchers.

Interesting idea mojo, rolling back to old posts.

Maybe I’ll compare our serial numbers and see who’s got the older speakers and possibly the half inch voice coils.

That would be very interesting. If all other factors are the same, I'd say it has to do with the amplification.

Maybe an easy test would be to just try my receiver on his speakers next time we meet up.

He’s using a vintage HK with raspberry Pi / volumio fed Spotify.

Same lacklustre tweeter sound when we play his turntable too via the vintage HK.

Then he comes here to my place and we just jammed some Hanne Boel and Larry Carlton and he commented that my tweeters were soooooo smooth. Go figure.

Maybe the ferrofluid in his tweeter is no longer ferrofluiding.

Oh interesting. Right. I suppose that’s a possibility. I’ll have to read about ferrofluid properties and shelf life.

Wonder if there’s a way to rejuvenate the fluid….
