Among the best known
of ADS two-way systems are ADS Minature
Speakers. Their introduction shocked the audio world and clearly established
ADS as a leader in miniaturization technology. Miniature or not, ADS speakers
have consistently delivered the greatest performance for a given enclosure
volume. ADS also builds some of the most sophisticated and prestgious
professional monitoring system in the world. Chosen by the most critical
recording and broadcast engineers in the industry. ADS speakers have gained an
enviable reputation for advanced technology, superior design, uncompromising
quality, and pacesetting performance.
It should come as no
surprise, therefore, that ADS produces some of the best two-way bookshelf
speaker systems that money can buy. The ADS L520 (L420 and L620) are results of
the very same technology which has put ADS Minispeakers at the head of their class.
They incorporate many elements of the largest, most expensive ADS professional
Monitor. They are designed and built with the same "old-World" care,
attention to detail and quality components.
Value is getting
more for your money
The L520 (L420 and L620) offer a degree of
quality and performance rarely found at any price. But don't take our word for
itt. Compare their specifications, quality of construction and sonic
performance to the competition. Compare the
L520 (L420 and L620) not only to other speakers of comparable size and
driver complement, but also to larger, costlier speakers. Buying a similarly
priced speaker simply because it is bigger or has more drivers may well prove
to be false economy.
The L520 (L420 and L620) deliver tonal accuracy,
wide frequency raange, low distortion, high efficiency excellent stereo
imaging, fast traansient response and wide dynamic range which set new
standards for two-way speaker performance. Their advanced design, lavish
construction, uncompromising manufacture and extraordinary performance ensure
untiring musical entertainment and uncommon long-term value.
