What is the best HEAVY METAL speaker?

I get that you don't agree, but you would be wrong, except for that last bit, which I agree 100% because that just happens to be true of most audio systems.

Orchestral material has plenty of sharp transients. Tell you what- find your self a copy of Das Reingold, on Decca or London ('blue back'), conducted by Sir George Solti. Put on side 6 about halfway through and crank it up as hard as your system will take. Make sure you let it play all the way to the end.

When Donner's hammer creates the Rainbow Bridge- its a bit of a transient :) Its also pretty metal. Norse gods- what can be more metal than that? But hang on till the final fanfare! Many systems just can't play this disk at full whack. You need power in the amps and efficiency in the speakers. That's just the way it is, regardless (for the most part) of the music genre. If you want electronia to sound its best with all the bass impact, you need exactly the same thing. I can't get my own band's records to sound right unless I crank them up too. Some music just needs power, without coloration. Metal is nothing special in that regard.

"That's just the way it is, regardless (for the most part) of the music genre. If you want electronia to sound its best with all the bass impact, you need exactly the same thing."

That is true.

Of course its always hard to define what is good and what isn't. In this case its better to talk about performance in regards to ability to deliver the most challenging musical passages at high volume. You will probably almost pay more for better performance on a larger scale, but what sounds "good" or not is subjective and way more up in the air.

If you are reproducing music only on a small scale and with limited volume, then the world is your oyster. :-)

JBL-LSR 6332?

Well, I guess classical is only well-reproduced on dynamic cone speakers, because I've never heard metal well-reproduced on anything other than that. It's gonna break the hearts of Quad and Maggie owners that their speakers aren't that good.

The JBL LSR is a good speaker for heavy metal. I know someone who had them, and I heard them before he sold them. He played a Metallica album, and it sounded really good. However, he had subwoofers going at the same time.
