Most of you probably think of JBL as a manufacturer of affordable high-performance speakers, but the company offers a truly vast range of consumer and professional models.
The K2 S9900 ($15,000 each) is the best consumer speaker JBL makes. It's a massive thing, weighing in at 182 pounds, and it's armed with a 15-inch woofer, 4-inch magnesium, horn-loaded midrange, and 1-inch magnesium horn-loaded tweeter. It can handle amplifiers as large as 500 watts a channel.
The JBL K2 S9900 will be equally at home in ultra-high-end music and home theater systems.
The K2 was originally developed for the seriously finicky Japanese audiophile market. There it has already achieved legendary status, and it was years before JBL brought it home. American hi-fi at its best.
I haven't heard this latest version of the K2, but I'm somewhat familiar with the previous K2 S9800. That one's sound was huge, incredibly effortless, and capable of delivering truly lifelike dynamic range. That last quality alone goes a long way to making reproduced sound sound realistic.
If you can afford the best, make it your business to hear the K2.
