KAM Cube 360 and WHY It Moves so Fast

0:00 You have in front of you a light from Cam

Right guys, you have in front of you a light from Cam. It's known as the Camcube 360. Now this is a light on steroids. If this was a stallion and it was set into or put into a little field with a load of mares, it would be on them like a tonne of bricks. Pretty much make them all pregnant in about five seconds and carry on to the next blinking field. It is a monstrosity, but it's tiny. It is completely efficient, it's very fast, very bright, very agile, and it's symmetrical. It's small. The centre of gravity has been put directly in the centre of the two arms so it can move with ease if... On the other hand, let's say this was a huge big moving head because it's big and cumbersome, it can't move as much. So let's take that or move as fast should I say but again that's depending on the cost of the moving head and of course how it's made. Let's not go there because I don't want to try and confuse the issue. Now let's take that analogy from this Camcube 360 to a speaker system.

1:10 This in greater detail for

Now let's imagine, alright that is a 12 inch single. I'm going to try and explain this in greater detail for the partially sighted. Let's imagine that's not a 12 inch single but that's an 18 inch bass driver. In my right hand and in my left hand I have let's say a 5 inch driver for mid and top. Now if I'm moving the 18 inch driver away from me, a couple of things are happening. One is I am pushing that away from me. I am pushing towards the air. And the other thing that's happening is I'm getting friction from moving the air away from me. And then when I bring it towards me, I'm getting the opposite friction from the air and I'm also trying to pull it towards me as well. So what's happening is the bigger the diaphragm, the less efficient it is because it has to move more air towards and back, towards and back. Whereas if you look at a small speaker, it doesn't have to move so much.

2:08 The bigger the speaker, the lower the sound they will make

Relatively faster. That's why small speakers tend to, most of the time, generate high frequency sounds or mid-frequency up to high frequency. The bigger the speaker, the lower the sound they will make. That is why big speakers generally are less efficient than smaller speakers. So for example, let's say you're doing a night for 50 people. Pretty much all you'd need is a set of 12-inch and horn. You know, so long as they're good quality, I would say 300 to 400 watts per speaker should suffice. If let's say it's for 50 people or more, then maybe you need a set of bass cabs. Again, 300 to 500 watts maybe per bass cab. Any more than 100 people, then you need to maybe invest in 18-inch bass cabs or maybe better still...

For mid and top, so you get more clarity and quality of high sound. So again, going back to the Camcube 360, this is why it is efficient because it's small, it's compact and also how it's made and it's actually quite bright as well. Practice and enjoy. Thank you.
