Your input will influence a DIY business decision.
Have listened to the Volla and came away impressed.
Thanks - noticed that the earlier Volla had the G1 tweeter whereas the newer Volla has the APR 1.0... heard great stuff about the G1 but nothing about the APR 1.0

The second 2-way would likely be the Leisure 5... as a lower cost alternative to the Volla
