I wonder what is the difference between 0.4x one driver karlsonator and 0.53 with two 3fe25-16 in terms of midrange and highs only.Is there a better image, soundstage with 0.53x? I already have a subwoofer but I'am afraid I do not have the necessary listening space for a 0.53x...

I am slowly working towards this as my first speaker build.
I just bought exactly those drivers for second hand.

Did you use a particular guide?
I've got a bit confused by reading too much on it.

Mid and highs are similar but more bass and more punch in mid bass. Feels substantially bigger sound stage with 0.53x. I like to think of 0.40x as desktop near field speakers and 0.53x as full room speakers.

I am interested in building a plywood version of the .53x with the dual 3FE25s but my wood working skills are limited. Is there a source to purchase a flat pack?

You might drop Jhofland a PM. He may have one you can get.

My eyes are playing tricks on me. I was making a root beer float and thought I saw a Karlsonator on my ice cream carton. Turns out it was the Eiffel Tower.
