Nice review !! It’s a pity Revel speaker’s are not easy to spot in Europe. I wish I could demo the M16 and this M106 and appreciate what Amir’s has listened.
The On-Axis is indeed very good but certainly not enough to achieve golfing panter, however everything gets fixed in a magical fashion with the PIR which is almost textbook.
@amirm With so much speakers measured already and the constant fact you keep enjoying speakers that has tilted down response (harman target). Can we start having some slight supposition that as a speaker manufacturer, the way to go is not to design for On Axis or LW flatnes/neutrality,
but all it matters to achieve bliss comes into tailoring the PIR and low-distortion?
Im really intrigued which tricks or methods helps the design process to tailor PIR...or is it just trial and error empiric work until it gets the target ? Couls PIR be simulated by soft at designing stage before even start prototyping?
