The year was 2002, and we moved into the new house. My small studio no longer had room for 4311 studio monitors, so I replaced them with the active powered LSR series, a decision that I was sad about because the the LSR's were so clinical as to be sterile, a more accurate, less colored speaker for mastering on but lacking the character and richness of the legacy JBL's.
In my malaise, I happened upon a store on Broadway called Gold Sound with the JBL trademark on the store front. I walked into one of the rooms containing second hand and consignment property, and my eyes locked in on a pristine JBL B460 low frequency system. I had coveted that speaker since the '80's but had never seen one. I wrote a $1k check for it on the spot and went to borrow a pickup truck. As soon as I got home, I picked up a call from the store's owner Ron Gold, who told me they had noticed a rattle in the loudspeaker. Devastated and forlorn was I, Ron surprised me with an offer to replace the driver with a brand new-in-the-box 2245H. This was original equipment, and it was very important to me to have the OE so I elatedly accepted. He actually just handed me the 2245H in the box and I installed it myself. I was so happy and the sound was terrific, deep but musical. I mention the 2245H because that is the same 18 inch low frequency driver used in the 4345.
The B460 tuning is lower, larger cabinet volume and thus needs a specific equalization that JBL provided with the BX63A crossover with equalization. I was never able to find a BX63A so I built one myself from the BX63A schematic using linear op-amp IC's, exactly per the JBL schematic. It worked perfectly and this survived until a lightning strike in 2008 wiped out the power amp and crossover. At that point, it was easier to use the new Crown 4000XTi which had a software configurable equalization, so I just copied the equalization curve that JBL had published for the B460 system, and no more need for BX63A.
I continue to use and enjoy it to this day. The lightning strike as well as setting the house on fire (although not destroyed), also wiped out the LSR active monitors. The cement tile roof had exploded over the driveway, and I wasn't quite made whole by the insurance settlement so when it came time to replace the LSR's I was under a budget constraint. I auditioned Mackies, Yamaha, KRK, Adam, several others but in the end the active monitors I chose were DynAudio, chosen in no small part because their sound character reminded me of the JBL 4311's where it all started for me.
Although I don't know the reasons for resurrecting the 4312SE, I would bet that a.) JBL are not seriously expecting to sell many, b.) they were easily assembled from the parts bin, c.) the 4310/4311/4312/L100 were more responsible for JBL's success likely outselling the 4345/4350 100:1 or more. But if you are lucky enough to own the 4345/4350 or L220/L222 or S9800K2, those are lifetime speaker's that would be as relevant as anything you could buy today as long as you have the room for them. I would love to own the M2 master reference monitors above all. Once you drink the JBL Pro KoolAid, you are changed for life.
