Magico - Wide vs. Narrow

Duke may be onto something. Snell A/III was wide, but also attempted to get close to hemispherical. The SF Stradivari isn’t just wide but it’s curved as well. Another wide baffle speaker with curves would also be the mid-tweeter towers on the Infinity Reference Standards.  The wings on the IRS were pure facade with nothing behind them.

You can test your theory by curving that sheet of cardboard… using math, ear / brain or both…

Peter was a gifted dude… RIP…

Cardboard is not a good speaker baffle material. Cardboard is very noisy in and of itself. Just putting my mouth near a piece of cardboard and humming lowly makes the cardboard vibrate like crazy, adding all kinds of resonances.

Just a side note, I was trying to replicate an experiment where you stretch a balloon tight over the top of a glass to make a trampoline surface that a ball will bounce on for a long time. That didn’t work out very well. But what it did do well was add a lot of reverb to my voice if I talked in to it. The kids were highly amused. So stretched balloons also do not make good speaker baffles.

Maybe something more dead, like a piece of carpet tile or mass loaded vinyl would be better for the experiment.

carpet is a lousy broad band absorber… but run your experiment, i’ve just got a blackbelt in design of experiments…

Ive also got a bunch of Panzerholtz 

The wings on the infinity had rear firing tweeters and they did that as well on the genesis 200 model.my new fr 30 has a rear firing tweeter.happy holidays and stay healthy
