The ADS L710 3-Way Loudspeakers Systems
It is difficult to
think of a popular speaker system that has endured as long as the ADS L710 have. It is also difficult to imagine that these two 3-way systems,
already refined to the highest degree, can be further improved. But for 1980,
the new ADS L710 boast several improvements from the inside out.
Now in
their generation of refinement, the l710 continue to uphold the
same standards of sonic performance which have made them two of the most
popular bookshelf speaker systems ever produced.
Features
Celebrated ADS
dual-woofer/dual-chamber design with new ADS Stifflite woofers for improved
bass efficiency and accuracy.
The new 2-inch
acoustic suspension soft-dome midrange driver has a stronger magnet assembly
for greater linearity,improved efficiency and transient performance, and lower
distortion.
The 3/4-inch
acoustic suspension soft-dome tweeter boasts the lowest moving mass among
drivers of its type (including tweeters which employ esoteric materials, such
as beryllium); excellent force/mass ratio assures lightning-fast transients,
superb damping, and extremely low distortion; small diaphragm diameter ensures
highly uniform dispersion and smooth, airy sound quality.
A newly designed
crossover network works in conjunction with the new woofers and midrange to
deliver improved linearity, efficiency and less pronounced room-boundary
effects.
New cabinets feature
radiused edges with soild walnut reinforcement inserts.
New acoustically
transparent grill lends a distinctive appearance while eliminating grill-frame
structure for reduced diffraction and improved dispersion characteristics.
New user-interface
panel features heavy-duty binding-post connectors and readily accessible
tweeter fuse with built-in spare.

Just curious about the fuse as I have this configured 3 way but the xover does NOT have any fuse or such at least not easily seen? I have a suspect dud tweeter which tested out OK when I disconnected so need to have a looksee and check crossover. Not sure how to check caps with the multimeter? PS the woof and mids are fine. Buying a crossover for these vinty's may be a challenge? Any comments from AKs. Thank you
