Short answer: the JBL L82 Classic MkII. It ranks #85 of 214 bookshelf speakers by sound quality, rated 4.0/5, at $2,599. The JBL 4312G ranks #103, rated 3.9/5, at $2,500, $99 cheaper, a saving that is not big enough to make up the sound-quality gap.
The case for the JBL L82 Classic MkII: The 2023 update keeps the 8” pure pulp woofer and 1” titanium dome tweeter with a revised crossover, a cast frame woofer and bi-wire terminals, rated 44Hz to 40kHz (-6dB). The tradeoff: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from its measured predecessor.
Why pick the JBL 4312G: The current 4312 keeps the three-way layout with a 12” pure pulp woofer, a 5” midrange and a 1” magnesium/aluminium tweeter in a waveguide, with front-firing ports and 90dB sensitivity. The catch: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from its measured predecessor.
Buy the JBL L82 Classic MkII. It is rated higher for sound quality, and the $99 you would save on the JBL 4312G does not close the gap.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: JBL L82 Classic MkII 3.7 to 4.3; JBL 4312G 3.6 to 4.2). Treat this verdict as provisional.
