Here is my little feedback on the headrush 108 vs CLR
They are rather correct as wedge or backline guitar FRFR monitoring.
it has a good sound reproduction in the spectrum of low to low mid.
Beyond this freq range it's worse than the CLR for example (which I also have), but for the low, it's definitely better than the CLR
Strangely and pleasantly, i find sensations quite similar to a real cab with it without adding too much high cut in the cab block.
On the side of weight (9.2kg), dimensions and price, it's happiness.
The CLR NEO weight is 15kgs (33lbs) FYI.
CLR is better in term of dispersion angles (coaxial HF driver)
In term on power HR 108: 126 dB continuous (dB SPL @ 1 m) vs CLR 120 dB continuous (dB SPL @ 1 m)
I will try to make a more advanced comparison in the coming months if it interests other people.
I hope it can help you make your choice easier
