From my POV it's a matter of EQ'ing your FRFR speakers to flat frequency or taste.
I disagree with this.
I have tried more speakers than I care to mention.
Yes, all can be Eq'd to sound 'similar', but that does not account for quality of components and the tone/sound it produces.
Easy (drastic) example is Seismic audio vs. Atomic CLR.
I could Eq'd the Seismic to sound similar to the CLR. But after about 20 minutes of playing through the Seismic, my ears needed a rest.
It sounded similar, but the tone/quality/pleasantness of the sound....was DRASTICALLY different.
Seismic is a drastic example, but I've had the same experience with other speakers as well.
I (regretfully) put my current PA speakers (JTR Triple 8's) side by side with the Atomic CLR.
I could Eq them to sound 'similar' again, but the Atomics just had a sweater top end. No amount of Eq can change that.
It made me mad because the JTR's are way more expensive (and I already bought them).
So price doesn't always mean better quality/sound....BUT there is still no way to Eq a bad speaker to sound 'as good' as a well built, high quality speaker.
(for the record, the JTR's are still great speakers)
As for the JBL SRX-712, I tried one a few years back and thought it lacked low end.
At the time I had it side by side with an RCF NX12ma. RCF carried more low end....but taking that out of the equation....they were like Coke/Pepsi.
Both sounded great, it was just a matter of personal taste/preference.
Since I already owned the RCF, I just stuck with that.
I will also say that I've tried the RCF NX12ma vs. a CLR.
If the RCF is 85% perfect, then the Atomic would be 90% perfect. Just my opinion.
That's about all the info/opinion I can give on the topic as I've never had the CLR and JBL side by side.
Since you're in NY and I'm in MA, you're more than welcome to ship me a JBL and I'll track a video of them side by side.....just throwing it out there.
