The Sanders 10e's are as close to perfection as any speaker system I have ever encountered.
The Sanders are a benchmark of speaker design, a design that is superb in all respects and in some respects raises speaker design to a level never reached before.
The Model 10e is indestructible. Even very high input signals will not cause arcing. A major bugbear of 'stats has been eliminated!
The 10e's have effectively unlimited dynamics and definitely adequate bass power and full extension.
If you wanted to call the Sanders 10e the best speaker ever, you could definitely make a case.
