I said- You seem well versed in radar, but a loudspeaker woofer will not beam unless there is a fundamental x-over design flaw and it is getting way more power than the tweeters- The waves are simply too big to localize- they reflect seveal times before they even reach you ears- this is why you only need one subwoofer and it can even point at the floor!

This means that the only way a woofer will "beam" is if it is receiving a much higher input than the other drivers. This wont be true beaming as I think I've established that that's impossible with a woofer's low frequency, but beaming in this sense would simply mean that it was playing noticeabley louder than the other speakers.

Nic said- For bass frequencies, you need a pretty wide bass driver to notice beaming, but it does happen.

then he said

Nic said- It is a fundamental law of physics and occurs because of wavelength and size. Sub-woofers aren't typically wide enough to induce noticable beaming at low frequencies,

Glad you finally agree with me, but-this begs the question-if a sub aint wide enough to do it what is?

Nic said- And as for paper cones, you'd be hard pushed to find one that wasn't treated in some way. No one uses pure 100% unadulterated paper for loudspeaker cones, they are all treated in some way or another

Which was my point several posts ago. Glad we finally agree.

I think you are a little confused with the term 'beaming' (sound being louder directly in front of the transducer, than at the sides). If you want to induce noticable 'beaming' from a sub, then mount it flush with your wall and stand well to one side. The wall will act as a sound radiator throwing all the sound forward. Anyways, we've probably whipped this one to death now :=).

Ok this is getting way beyond the question of desdgl. Consider the topic closed.
