HCCA was really a way of cheating when you think about it - take a 50 watt per channel amp at four ohms. Four of them gets you in the sub 500 watt class! Wire them up for 250 milli-ohm operation and you really have thousands of watts of actual power providing your wiring and electrical system can take it!

That sounds familiar! ;)

The original was a 1bit (5.6448 MHz) recording.

Wallplugging is popular for blowing home speakers. Some of the better built drivers (woofer) and pro audio can handle it producing a really LOUD 60Hz tone. Step up to 240VAC for even more fun. (or wire dual voice coil drivers in parallel!)

I had an old Legacy 15" sub that I used to pug into the wall in electricity class in HS. Now that was fricking loud :D

Open it up and let it loop at full volume

WTF dude, not cool!

Thats... HORRIBLE!

I thought you were leaving the forums? I made a thread about it and everything. You are quite the disappointment.

No its a legitimate file, it just sounds terrible. I listened to it at high volume on headphones and it made me feel nauseous

So just throw them away.

Failing that, cut the ends of the speaker's cabling off the main unit (or unplug them and cut the plugs off) and stick them into the ends of an extension cord, and plug the extension cord into the wall outlet.

now how is that more fun than listening to music and all of the sudden the speaker blows out the dam front?

It's more fun because it's also more dangerous. You might zap yourself, you might throw a breaker, start a fire, damage some other equipment in the process, etc. You're not going to blow those speakers connected to the stock power amplifier they came with. You're going to need to connect them to something that can damage them - a high-powered amplifier with no protection circuits or direct to live current.

Watch this:

How is that NOT fun?

It's not the music that destroys speakers, but the poor quality signal square wave sent to them by low end underpowered amplification. Use a cheap end under powered amplifier/receiver and killing them should be no trouble regardless of the track played.

If the voice coil(s) can handle the thermal power delivered by the amplifier power supply the speaker will survive. ;)

Here's a clip that WILL damage speakers if played at higher levels. 16Hz sine for the woofer and 16kHz sine for the tweeter. Mixed in at equal levels and not too harsh on the ears while doing it. 16Hz was chosen because High Pass Filtering (HPF) of popularly called "subsonic filtering", etc. does not knock it down too bad nor make some amplifiers go whacky driving woofers way out of control. Most speakers will distort audibly long before producing a real 16Hz fundamental that is more heard than felt but at 100dB 16Hz is heard well.

Here it is - just remember to use LOW levels when playing back. Use even lower levels if listening to headphones. The 16k part is piercing!

The bass line on "No Sunshine" by DMX will cause problems.

Find an old computer data cassette tape and play it back in your home stereo's cassette deck. Those tapes when played back on audio equipment produce square waves.

Norwegian Dawn and I run a 1000 seat theater with a 90,000 watt sound system so do the math. ;)

Those would be the ones.

I wouldn't have remembered those details...how did you?

A friend showed me a pair of KEF 107 bass bins with XTR10's installed in them. They were driven with a QSC Powerlight 9.0 amp and could handle it! Two 10's in a coupled cavity - sort of an isobarik arrangement where the common area has a transmission line vented to the listening area. Extremely tight, snappy response at 90Hz you'd expect from a 10 but could play very loud and clean at 20Hz which was unheard of. But it took power to get there and the woofers handled it!

I have a recording called "Norwegian Dawn - Blizzard '06". I consider it one of my 10 highest quality recordings. It's in vbr ~400kb .WMA. I'm not sure if you have any connection, but if so the ownloadday inklay to more would ockray ^_^

Not as harsh as a digital square wave - data tapes will produce signals that will saturate the heads and it's not nearly as harsh as a perfect tri state signal would be.

If you have a deck with a microphone input, set it to record and use the record monitor (loop) feature of your receiver with the microphone next to the speaker! :Q

A turntable with the stylus parked on a record sitting near a powerful subwoofer is also a good way to create a rumble from hell if the system is powerful.

Actually the file format/encoding has no bearing on the quality of the original recording. ;)
