O6:
+ improves loudness
+ improves clarity
+ incorporates landscape tuning with good left-right balance
Tuning work will continue to improve transient performance at max volume,
and incorporate feedback from UTD and PAE tests.
R4:
+ Improves loudness
+ Improves clarity and reduces bass distortion
+ Incorporates a landscape tuning that balances left and right speakers.
Further tuning work will improve bass response at lower volume steps and
improve tonal balance to reduce sibilance. We will also incorporate
feedback from UTD and PAE subjective studies.
