JBL 4319 Speakers

Is anybody familiar with the JBL 4319 Speakers.
I can get them for $3000.00 brand new boxed. All I know that,
they are made for Japanese market. Unfortunately seller
wouldn't let me to unpack the speakers. Are they classic
JBL sound.
Thank you all in advance for any information.

Buddy, you need new glasses. There is the difference
between 4319 and 4312. Not just in numbers.
I bought the speakers anyway. Maybe my best decision ever.
My Focal Aria 948 are for sale. Can not come close to JBL.
