So you are saying you are using a 1.4" driver on a horn that has a 2" throat? Build the extension, or get a 2" driver. Honestly I would recommend the 2" driver. Lots of reasons if you have the time.

Please remember what Kloss told you about the WE snail horns. The were designed to utilize the capabilities of the 555 driver, which is a very wideband driver that goes really low, 120Hz or something. Unfortunately acoustic horns are not wide range transformers. The snail horns are beautiful, but an anachronism. Build one to look at if you want.

Your filter is -3db at 350Hz? You driver is operating a lot lower than that.

Hope this helps,
