JBL Speaker Upgrade - 4331A to 4333A conversion
How I turned my vintage JBL 4331A studio monitors into (almost) JBL 4333A 3 ways, using all JBL components. Please SUBSCRIBE to my channel. You can support my work at Patreon: patreon.com/audionautica This is a great improvement for what are already fantastic speakers. Just to clarify, the L300 is not a domestic version of the 4333A. They are similar in that the L300 has the domestic versions of the various speaker drivers, ie woofer, compression driver / horn and tweeter. However the enclosure is quite different. https://jblpro.com/en/products/4331a-... https://jblpro.com/en/products/3105-3... The components in this speaker are: 15" Woofer - 2231A Compression Driver - 2420 Horn - 2312 Diffraction Lens - 2306 2 way crossover (for 4331A) - 3131A (4333A has a 3133A 3 way x-over) Super tweeter - 2405 HF crossover - 3106
