    I really think you need more separation between those two boxes.

    Can you re-orient your system within that room ( iow; point the speakers a different direction and gain some separation ) ?

    Looks great Rob.

    86661

    Nice Blue, plus I love the look of the painted port-internals.

    Also the L94 lense is a nice touch .

    No wonder you thought the spider shim was meant to go inside the driver ( since you found a shim there when you removed the original diaphragm ).

    Yep, face-plant time ( too funny ).

    That plastic shim doesn't permanently live inside the diaphragm/magnet assembly.

    Is the sound captured "live", through the "optional" ME-1 Stereo Microphone ( seen below ) ?

    Hi Dino,

    The HF rolloff is really determined by the driver ( not the horn ).

    Here's the frequency response of that driver;

    Hi,

    It's definitively worth checking out Jerv's 4425 remake ( thread from 2006 )

    He nicely exposes/lays out the realities of working with the 2214H ( and a 1200 hz crossover point ).

    Hey Pete,

    You can safely ignore the impedance labeling from JBL , ( assuming the diaphragms are still original ) they all have the same impedance .
