JBL 4309 (football panther) vs PSB Alpha P3 (headless panther)
Yes, this is worth a discussion.
That commentary in the charts does not seem fair to me, that said I have a pair of JBL 4309's here and am doing some listening.
I can say that I have currently 6 or 7 pairs of speakers here that have Harman scores (and have owned more in the recent past)from mid 3's to high 5's (some that can be PEQ'd well into the 6 range) and as many more speakers with no known score.
I have more testing to do.
I wrote about this elsewhere but nothing can really prepare one for the sound of the 4309 based on the published tests. I find it is
much better than that chart indicates, and the Harman score indicates in terms of listening to music, creators of course might need flatter lines.
So far the 4309 sounds excellent to me and mean it. As an example I did a bunch of testing on a Polk T50 set (same base Harman score as the 4309 of 3.7 so an interesting testing companion)and while I enjoyed the process and the music enough I was ready to call it a night. Since I planned on testing the 4309, I dragged myself to set them up even though I was "over" music for the evening. Man did that change.
I wanted to "take out" everything I have. A really stunning sound and one that had me absolutely energized again as if I had never grown tired of testing earlier. A completely different speaker from the T50, so much more realistic sounding and clear and "open" if I can use that word here.
There was no comparison for me at all, the 4309 was so much better in my sessions than the T50 (even the T50 PEQ'd to improve response) it is not even remotely in question at my place (GF had the same general experience without any coaching. She did know the prices.). Not to mention it can play really, really loud for it size with total ease - easily outpacing the T50(granted the T50 costs a lot less)
I have more listening to do and of course and perhaps take a few measurements in my room if they seem meaningful.
YMMV.
Just food for thought.
