The impedance of the speaker is matched to the output impedance of the amplifier.  Every circuit has a resistance of sorts also.  Impedance matching works like this -

Ohms law says that Voltage = Current(Resistance)
One definition of a Watt is = Voltage(Current)
Therefore Voltage = Watts/Current and Current = Watts/Voltage
You can derive from that - (Current^2)(Resistance) = Watts

Say you have a resistance (impedance) of ten ohms, but your load is 5 ohms.  Now your power amplifier is dissipating 2/3 of the power that might be dissipated by your load as sound..

So basically, your six ohm speaker will work.  If you start cranking up the volume, however, you may find that your heat sinks inside aren't compatible with the extra heat load, and your transistors will lose their magic smoke.

I suggest you look for a pair of speakers to salvage from a Hifi someone doesn't want.  Why a pair?  Because it sounds like you have a stereo amplifier (two different ones, one for each speaker) and your tone will be off-balance if the speakers aren't matched.

A humourist simply goes to 0 in my respectometer if gets into politics...

You also don't like The Simpsons or Family Guy, if I remember right.  I think you blew a funny fuse.

Completed Game Announcements / Re: Nanobots

This game is awesome and so are all of you wonderful game developers.

Now I want to make some nanobots, but I don't have the necessary nano-machinery or nano-love.  It's a little disheartening.  I also might mention that these are more like milli or perhaps micro-bots, because nano-bots would not be seen by the human eye.   ;D

I know if I found a thread on the internet from a girl I kinda knew raving about how awesome I am and posting my picture on the internet I'd be thrilled.  Just think about it!

Snapped by my colleague, thanks to her.

Where'd you get those bell bottoms dude?  Vintage or new?

Was the only other driver an old lady who only drove it once a week to go to church?

:D  Maybe not, but sounds like you were fed a line or two!

Plus the steering wheel is clearly installed upside-down.

I think you should go ahead and get the premium car / sell your family.

They're only holding you back at this point.

Oh, I forgot, there's a blue man group there, if you're interested in that.  If you don't know what I'm talking about, youtube it.

There's a historical trail through the city where you can see a lot of colonial places.  Faneul Hall is where a lot of political rallys and discussion took place (and where John Kerry conceded his loss in the last presidential election).  There were all kinds of trippy little graveyards by the old churches with carvings that looked like they came straight out of an old zombie movie or game (my state is very young, so we don't have that sort of thing here).  I had a blast just walking down the trail, which is marked on the sidewalks.

The favorite places I visited were MIT and Harvard, simply because I was about to go to college for the first time then.  MIT has a bunch of weird techno museums and research stations around it with robots in the window displays.  I toured the place with a student group hoping to see some cool stuff, but they just talked about the meal plans and showed the dorms like any other college!

If I had been over 21 when I went I might have had a lot more fun.. but being 18 and from Oklahoma what I did (wander around randomly) was pretty interesting anyway because I'd never been to a real major city then and all the quirks were new.

Eh, no, but there is a well-known earthquake hotspot on the Mississippi somewhere around there.  Once in the 1800's the flow was reversed because of a massive earthquake!

Hell, I barely open AGS.  I just come here to play games and laugh at all of the threads from the hilarious game writers.

It's a threat to my ability to find a mate if my potential mates think I'm only interested in men.

That's thinking ahead, our 85% male audience hasn't seen a vagina for the most part so the 15% female population might be appalled... or thrilled, however their personalities allow, by the sight of a cartoon penis-arm.

Black holes have event horizons.  Mini black holes have mini-event horizons.  Slashdot had an interesting article posted today about a new record for the smallest black hole in discovery.

Some people thought the atomic bomb would never stop reacting and destroy the Earth.  Most people knew the calculations said otherwise.. which is the same in this case, else they wouldn't do it.  By "not sure" they mean "not 100% sure" because they're scientists dealing with theory and nothing is 100% sure.

We take risks in the name of advancing humanity.  Being on this planet is a risk for more reasons than I care to go into.  By advancing technology we can make it less so.

It's more the other way around. The hot-to-not ratio is in bad favour, but when an Irish girl is hot, she's really hot...

Just like everywhere else, I'm sure the following rule applies:

1. Single
2. Attractive
3. Mentally stable

(pick two)

Would it happen to be the one in your sig?  You might notice dozens of people advertise their websites (commercial and private) in their sigs.  That's for whatever you want to put in there, inside the realms of size and decency.
