Reverb question

[tyrosguy85]

Hi all,
When I use my genos at home through its speaker system or my stagepas 400 my reverb settings sound really good but when I'm using it through my BOSE speaker using the L+R jack output I have to increase the reverb volumes!
On my tyros 4 i don't have to alter anything.
Any ideas
Cheers
JOHN.
