When did acoustic suspension become infinite baffle?

Cal Weldon · 17th December 2005, 04:46 PM

Todays rant.

Growing up, the two were quite different. How did we adopt the IB name to the sealed enclosure? An IB used to be a flat plane, large enough to prevent wave canellation down to 20Hz, and AC was any old sealed box.

Heck, I don't even hear the term acoustic suspension anymore. I suppose I should roll with the punches and get on with it but the whole thing rubs me the wrong way.

Never mind the 'sub' woofer thing

Cal,

I believe infinately baffled refers to mental state of a DYI'er when he can't get his newly built 50 foot square speaker into the living room.

I think accoustic suspension is what happens when you ignore warnings from the moderators about being rude or abusive.

Acoustic suspension is when the Vas/Vb ratio is less than 3. Infinite baffle is when the ratio is 3 or above.

So then... what are you thoughts on 'fast' bass

Stop it now Shin!

Fast Bass = Car Audio

Poobah, You're great.

Shin, Don't have to worry about the speed with my omni/multi/bi-directional speaker leads. They promise zero drag provided I elevate the amp above the speakers to not compromise the electron siphon effect.

Joules, I like it and I wonder if the speed of the bass changes with the choice of automobile?

Its the colour of the car that determines the speed. And purple is scientifically proven to be *the* quickest.

That's what my friends from the sixties said.

You know that is interesting... purple speaker wires are claimed to be fast as well.
