One woofer has been replaced by Harman International. The 4312M2 is popular as a miniature version of the 4312 monitor. It's a speaker with dry low frequencies, sharp high frequencies with excellent sharpness, and a compact yet comfortable speaker that can be played energetically like JBL. The exterior is good with no conspicuous scratches (Sasaki Shota)
Maintenance information: 2023.5.22 manufacturer maintenance completed (I have confirmed that the voice coil on the woofer part is defective. The woofer unit was replaced and normal operation was confirmed)
