So the JBL Synthesis 4367 with a 15” woofer wouldn’t be as good as the classic series?
The question isn’t which is better, the question is which can you return after an audition. The "better" part is subjective, your bank balance is objective. Make sure your choice fits what you prefer. I have a JBL system setup in the man cave with the Studio 2 series. I LOVE the way the 230 book shelfs present in that room, 6 inch drivers that go so loud the neighbors complain. The 15 inch drivers in that room would probably have the fire department at my door. I did audition the Studio 3 active versions which are praised morning noon and night but were too bright for my taste compared to the 230’s. I bought them right from the JBL website which DOES offer 30 day auditions with FREE shipping both ways if you return them. The 230's sounded good with my Parasound Zamp with 40 watts but when I drove them with 80 watts of Bob Carver magic the soundstage blew out from wall to wall, floor to ceiling. I would have NEVER known this from a chat room. You gotta get em in your space, with your amp, your music, and let the music play. If it don’t ring your bell, send them back.
