Summary:
JMLab always been an extreemly good speaker manufacturer.They use trustworthy FOCAL driver for all their line of speakers.
Price wise this SYSTEM 12 is excellent compared to others (paradigm, mirage, Definitive Tech, etc).
These speakers deliver accurate and detail tonal and music without hurting your eardrums. The brightness is soft but clear. The base is tight and precise.
In short, this $700 speakers is in the class of $1000-1500 speakers. This is definitely worth listening to.
For the money you can't find other better deal. I'll give 6 stars

Summary:
After 2 weeks listening to my new Paradigm Monitor 7 ..... I switched to JMLAB system line 12 .....Monitor 7 is not a bad speaker.... but JMLAB's tonal, detail, and softness beat the hell out of Paradigm monitor 7 ... (all paradigm speakers are very bright).

My new babies can go down pretty good ..52Hz .... and smoothhhh with bass that's not boomy at all. Midrange is excellent .... (is use FOCAL driver and tweeter)

I listen to jazz, classical, pop, rock, alternatif..... these babies played all extreemely well.

If you want to get a pair of speaker ranging $450-700 ... get these babies... you'll not regreted later..... btw I paid $600 for a demo JMLab.
