QSC K8 Powered Speaker a Look Inside

0:00 Something very simple is going to happen here

All right, ladies and gentlemen, something very simple is going to happen here. Here is my drill. Here is the K8 from QSC. It's a powered speaker. It's got an eight inch driver. It's also got a horn in there and it's rather punchy. I'm now going to not pull it apart but let's just say when I was younger. Let's just say when I was younger. My mum and dad got really pissed off because I used to pull things apart, including a carriage clock and a two-way radio, part of my dad's car. The list goes on. And a plug, and I electrocuted myself, thus why I've got burn marks here. So don't pull plugs apart, especially when they're actually still in the socket. Don't ask me how it happened, but it did. Anyway, I'm now going to pull this apart. Now again it's a powered speaker for anyone out there who does not know what a powered speaker is. It's got internal amplifiers that will power the speakers so there's no need for an external amplifier. It's from a company called QSC, it's known as the K8 and it's going to be pulled apart right then.

2:31 This is my long pointy thing box up there

Bear with me. Drill, right way, and off we go. Right, just stay where you are. Jobs are good. Right, on the back of this speaker there are two sets of screws. Now if you want to pull the entire amplifier out, you need to undo the outside screws. If you undo the inside screws, you will go into the workings of the amplifier. Now, what QSC have done, which is very clever, they've made sure that all of the amplifier is in one separate compartment. So, what that means... Let me just wind it from here. That's a long pointy thing. This is my long pointy thing box up there. No, that's not right. Right, I'll... No. No, I'm not going to pause the camera. I'll just make it go fast. So one second and now. Right, got it. OK, so pull that out now. And there is the amplifier in all of its glory. Now, it's pretty much like sort of an oblong type bowl. So the only part protruding from it...

4:12 Something along the lines of

The cables going to the speakers. Now, of course, that will give the speakers power. Inside here, you have all the workings for your amplifier. So I'm going to pause the camera now and you can come over here and have a closer look. Bear with me. Right, there we have it. There is our 8-inch driver and that is the magnet. Inside there is the coil. Of course, you have two magnets, positive and negative. And the coil will move backwards or up and down inside the magnets. And then above here you have the horn, also known as a CD horn compression unit. Now this here will give you the high frequencies to sort of let's say upper mid. And then the 8 inch will take over from that. Now an important thing to think of if you're going to look at something along the lines of the K8.

Is that these will and these will not do big gigs yes no i mean yes and no i mean well they will and they won't okay they won't do big gigs if you expect to turn up like a muppet with two of these for 300 people because you'll pretty much look a muppet they'll sound okay But when you start wanting to play some wicked drum and bass, it's not going to happen. They will do gigs though for 300 people on the other hand if you have them and use them in conjunction with some bass cabs. Now the beauty about a system like this small from say 12 to about 8 any smaller and you're dicing with death really but 12 to 8 inch, what you're doing is you're getting good quality, good fidelity of sound. You're getting a speaker system if you run bass cabs with it that will be far more efficient than if you do not run bass cabs with it. So the likes of say a 12 and a horn or an 8 and a horn...

6:46 See, I am the DJ Tutor and I know everything

Is great with an 18. if you go to a 15 then you want an 18 you could even use 15 inch base calves as well so i have pulled apart the housing now let's have a look inside of there so i'm just going to pause the camera hold on I do know a lot, a great deal about internal amplifiers. So what you have in front of you is the plug-in thing, the Wimsley Whatsit. There's the Fluctu Capacitor. No, that's the actual, sorry, Flux Capacitor. That's the Zoomily Zomzom. That's the four kilowatt per hour monstrous gadoobly. Those are the Dingley Dangley Doos and those are the Screwy Inbits. So just take a look in there. There you go. See, I am the DJ Tutor and I know everything. No I don't. Okay so there you go that is the K8. Now apart from size and possibly the internal workings on the amplifier pretty much the design is not dissimilar to the 12 and the 15. Of course it's not going to be exactly the same because

There will be definite difference of specifications, but what you get is an internal amplifier that will power the speaker, in turn give you a great sound. So I hope that's been a help and also what these sorts of videos do is show you what's inside of something without you doing it. Now if you do... If you do something like this at home, potentially you could void your warranty. So, oh shit, didn't really say that. Just don't do it, alright? Because yeah, you could potentially void your warranty. In other words, you get a brand new item, you think I just want to see what it's like inside. You open it up, you put it back together and guess what? You could have voided your warranty because some companies I haven't seen it on here but some companies will actually have

Little bits of glue on the inside of the screw. So as you screw it out, the glue comes away. So the people who open them up know, the professionals, that if the glue's not there, it's been tampered with. So just be wary. I hope that's been a help. There will be a link in the description to the QSC website where you can get more info on the K8 and all of the other K-series. I'll finish off with practice and enjoy. And this video is going out to Emma. Take it easy, bye-bye.
