The most fun you can have in audio is DIYing your own speakers

Would these classified as diy?

Here is a pair speakers I have been Interested in for awhile now, whilst not perhaps fully a diy job as all the hard work has been done. Besides I am crap at Math and can't cut straight for toffee. I knew there was a reason for my purchase of 9 piece De Walt set, just haven't found it yet, lol.

Have you ever heard these speakers:

I really like how they look and if they sound good, might try to build them.

I've been thinking about trying to build some speakers for a long time but haven't done it.  I'm going to start simple, probably a little 2 way from Madisound.  One thing I'd like to do is build a box that is stiffer than the 3/4" MDF.  I was thinking about making the standard box, or very nearly, and then instead of wood veneer using some porcelain floor tiles.  There's a huge variety available and those things are incredibly stiff.  Has anyone ever tried that?

gndrbob - I'm afraid I don't know much about full-range single driver speakers, you are better off asking in the DIY audio's full-range forum.

Best,
