If you're familiar with LDL, you know we don't like talking "breakthroughs".
It's become a tired word for minor improvements.
Yet what else do you call a new transducer design that reduces IM distortion up to 2% and increases bass response as much as 6 dB? That's exactly what happens with the new Laminar Core Transducer we're using in our new LDL 749 Professional Reflecting Speaker System. It's a difference you HEAR. The first transducer that doesn't fight itself. In conventional dynamic loudspeakers, normal voice-coil action produces eddy currents in the magnet structure-currents whose magnetic fields oppose speaker motion, increasing IM distortion and reducing speaker output.
Especially on heavy bass passages requiring long cone excursions.
By utilizing a magnet structure with laminated pole pieces (instead of conventional solid ones), the professional's transducers virtually eliminate distortion--producing, power robbing eddy currents. Resulting in cleaner sound. And greater efficiency in the important bass region.
A "Fearless" speaker: the new industry standard with the Laminar Core Transducer, we sincerely believe we have set a new industry standard in speaker performance. Without being facetious, we can say that the new LDL 749 Professional Reflecting Speaker is equal to the challenge of flawlessly reproducing the tonal and spatial nuances of any musical performance, at any volume level, from the softest pianissimo to the human pain threshold, if need be.
Believe your ears. Not your eyes. We don't expect to convince you here: there's nothing like listening for yourself. Next time you visit your LDL dealer, take along a familiar record and listen to the way our new LDL 749 Professional recreates the fidelity and spatial effect of the concert hall with its precise combination of frontal radiation and panoramic reflection.
Then look at the price tag--it may amaze you even more than our sound.
