F10 of 40dB from eyeballing quickly. Looks like that means JBL quotes frequency response as the F10 point even on professional gear. Time to measure the JBL M2... I wonder how they fixed the issues with the 7 series which seems identical but smaller, with obvious problems like that crossover dip which is not present in things like an 8331/41 which is a scaled down 8351. Guess it's cheaper so that's the compromise they chose to make though.
...But even with the "cheaper" excuse, price to performance wise, the 5.1 score on a Kali IN-8, and a 4.7 on this... With an older brand that has more resources and hopefully more engineers, and more than double the price, I expected a lot more.
I need to listen to the JBL 7 series in a different room now though to see if that changes my mind. In a partly treated demo room comparing them to other monitors by Focal, Adam, Neumann, and JBL, the 705 set I listened to sounded like the tweeter was working very hard and couldn't quite make all of the tones it was being asked to make. Maybe it was the reflection off of the desk, or maybe the strings and vocals I was listening to were playing around the cancellation area?
This model also hisses a little above my limit, and more than the $100 Harman Kardon Soundsticks I had in college and didn't notice. As much as I love Harman's research, and Revel seems great, the more I see about JBL, and the more I listen to their speakers, the less I like them as a company.
