I use 2 Bose L1 Model II connected to a Tonematch 4S.
One is the older model with Firmware 1.4. It sounds great and has a quiet fan.
The other model is newer and comes with 1.5. The fan starts immediately at low speed, but anyway you can hear it.
I learned that this is normal behavior.
Actually I do not like the new normal and I'm asking myself, whether I could try to use firmware 1.4 with the newer model to eliminate the noise, or if there could be created a new version 1.6 to reintroduce the old fan behavior.
Talked to the Bose support today and I heard that it might be a good idea to hear from you guys whether you would also like that idea and support it!
So, what do you think?
