L-505A and L-707 Main Speaker
1. A sealed enclosure tuned for the best impulse response rather than a low-
end extension. We strongly believe that various kinds of vented enclosures
always cause coloration that does not deliver reference accuracy.
2. Sturdy enclosure made of 1" (25mm) thick MDF with internal bracing to
bring unwanted resonance and box coloration to an almost nonexistent
level.
3. Stiff Glass Fiber Cone mid-woofers with low dampening rubber surround,
die cast chassis, and a low distortion magnet.
4. Neodymium Ring Radiator - super low distortion tweeters with frequency
response up to 40 kHz and extra wide dispersion.
5. The absence of a grill in front of the tweeter. Our laboratory and listening
tests prove that even the most transparent grill fabric causes high
frequency comb filtering.
6. An acoustic, rather than an electronic, time-coherence of tweeters.
7. Unique tweeter surrounding. Perfecting the tweeter environment appeared
quite possibly to be the most challenging aspect of the design. The goal
was to eliminate the edging effect by carefully shaping the tweeter
surrounding with specially designed Belgian foam.
8. A low-order crossover for the best phase response. We also selected the
lowest possible crossover point to deliver the best transient response.
9. Premium quality crossover parts. Foil Inductors wound on a wooden core -
with their skin effect conductivity - provide performance unmatched by less
