Wed, 02 November 2005 05:34 Quote: the reason you dont hear the high freq wave through the mdf is because it is reflected NOT absorbed. I'm trying to keep it simplfied, by using simple words, yes there will be some reflection but No, we are talking about a compression waves, not a transverse waves, a whole diferent thing.Transverse wave will reflect a major of there energies, compression waves don't. The wave hits the MDF and stops on the other side since it needs to move that material ie compress it in order to pass through. The wave needs alot of energy to do this so most of energy dissipates or is "absorbed" in to it's surrounds and some of it will reflect. Bass will tend to pass through this and have some too reflection. MDF-> May I should say use a pillow which doesn't reflect! Anyhow From would your saying, we'd hear echo's... Reflected sound, unfortunately,this is not the purpose of the orignal statement,it was to prove what has more engergy, Low or high frequencies Quote: I dunno if this was directed at me, No, so far your on track, it was for everyone Quote: light, This get stranger too... has Momentum, by no mass,an acts like a wave and a particle... but it does stop when it hits a soild, non-transparent object, cause it hasn't got enough energy to pass through it.... Quote: tweeters need less energy because they are very directional, No, cause you even said it... Quote: a longer stroke increases AMPLITUDE. you are howeever correct in saying that increasing the stroke increases energy Also to produce a high frequencies, you need to move things very fast, and to do that, things need light and therefore small. They are directional cause they don't have enough energy to move/compress the large amounts of air, only the bits directly infront of them. You don't and can't feel a tweeter shaking the crap out of your body do you? [Report message to a moderator]
