JBL's newest
tree-way bookshelf loudspeaker is a happy blend of the ideal and the
attalnable. Here's how they met.
We built a
superb system called the l212. it's an absolutely no-trade-off,
state-of-the-art., $1,700 system that hasredefined the upper limits of hogh
performance sound.
Wouldn't it
be great if we could build a loudspeaker that would sound as expensive but
wouldn't be. The answer's the L50. you can take a pair home for $550. but
before you do that, turn them on. The sound is everywhere. No matter which way
you turn you're in the center of the music. Here's what's heppening to you.
You're
learning the new geometry of sound. The third dimension: Bass guitar, left
front. Saxophone behind. Drums deep in the middle. Lead guitar front right.
Flute behind. And the sound is never altered, colored non caricatured.
The silent
hero of the L50's smooth, seamless sound is the best crossover network you can
buy - the same kind we put into our studio monitors. You owe it to your soul to
hear the L50's. and be sure to ask for them by their first name: JBL. That
guarantees you'll get the same craftsmanship, the same components, the same
sound heard in leading recording studios and concert halls, around the
world. Come hear the L50's, come see
what it's like to get close to perfect.
The precise
vertical alignment of the transducers insures near perfect stereo imaging.
