Has anyone purchased or listened to the current 15" 3-way 4338 & 4-way 4348 JBL moniters available in Japan? How do they compare with their predecessor units, 4333/L300 & 4343/4344/4345(18") we have over here and talk about? Costs are pretty high at ~$15k for 4348 pair, plus shipping to NA but maybe there are some used available to make reasonable if they are worth it and much lowere 4 than the new DD66000. I know the component drivers are all different from the oldies.
