I have a pair of theese horn/lens with the 1" throat adaptor, and I have a pair of McCaully horns who look like the JBL 2391 horn/lens. Does the sound of the JBL 2390 be superior to the McCaully, because I use for a long time the McCaullys and it is too far in my memory how they sounded(2390). What if I put back the 2390 on my JBL 2420, would it sound better? The woofers are K-145.
