...I also bought the HR 108 to use upstairs - due to size, weight and no fan.
It’s good in that role.
BUT.... there is no way it can compete with the Yamaha’s 10” driver for overall sound/authenticity of the modeled cabinet and tone.. In my opinion (yes, opinion), the DXR is a far better sounding speaker with better realism, balance and ability to handle louder volumes as well.
I also found the 108’s bass response to be very “spikey”.
I like the 108 for $199, but to me, that’s all it’s worth. $199.... it’s $199 well spent, but it’s no DXR10. Not by a long shot. (That said, I can see it as a good option for a monitor speaker...)
Wow, that's not been my experience. Having gigged the DXR10, I was pleasantly surprised by the Headrush 108s. They sound better as studio monitors and as a FRFR speaker for the Kemper than my Yamahas ever did. Much flatter and fuller. I'm hugely impressed.
YMMV, of course.
