We really need some sort of group photo of all the 4-series JBL speakers because it's getting confusing trying to visualize the size.
Just from the 2-ways we have
- 4309 at 6.5 inches
- 4306 at 8 inches(but a bit of an outlier, with the white woofer and non-HDI horn)
- 4349 at 12 inches
- 4367 at 15 inches
No 10 inch model here, but there's a 10 inch 3-way. And don't get me started on the distinction between the classic L-series and the studio monitor 4-series where some 3-way studio monitors look like they belong in classic. Super confusing lineup, but I guess there's something for everyone.
