Hybrid preset combining Syva and Syva Low.
Use only with AutoConnect or when Syva and Syva Low are within 60 cm (24 in) from each other, that is,
acoustically coupled.
When Syva and Syva Low are more than 60 cm (24 in) apart, create a custom preset in LA Network Manager
combining [SYVA] and [SYVA LOW_100].
