And they sound pretty decent so far. Bass-shy to be sure but I do have them in an undersized box, vented 7 liter, but that's all I had ready to be used. Can't thank ya enough Paul C. It seems like there's a bit more in the midrange and up than I generally prefer. Others might love 'em like this because it's not like it's searing my ears off.

Measurements are coming soon. I ran a quick test to make sure I had tweeter polarity correct and it looks nice enough. I threw some Tonic Solfa at them first and the imaging is there. Van Morrison sounds a wee bit bright on Moondance (flute part does at least) but overall there's some good stuff going on with this little kit. I think Mad has a winner on their hands. These would be a great basis for a rather good HT rig.

Green trace is the baseline measurement for the speaker as a whole. Burgundy trace is with tweeter polarity inverted. Orange trace is the woofer with the LP filter in place and the blue trace is the tweeter with the HP filter in place. I might take some measurements of raw driver response a bit later. Impedance sweeps will be later once I drag my laptop back here for that.

They obviously treated the tweeter very nicely in not pushing it too low. The woofer isn't worried though and is well managed. Back to listening to them now.

I'd wager that if you fill in the bottom, the top won't sound so bright anymore.

They don't look like they need anymore BSC???

I wonder how many Madisound has left?

Can't wait to hear mine! I even got a heater for my garage so I can get 'em done sooner.

Thanks for posting the measurements, they look good! :cool:
