Hi guys. I guess, this forum topiks are about some DIY projekts, experiences, or etc..what we did, can do, or show own dreams which came true  :)
 For that, even i no have made all pictures step by step, how i made my speakers, but main of them i have. This is my 2 years planed and 3 months made speakers project. Base is on Davis Acoustics 20DE8 wide range driver, plus add RiPol subwoofer and on the top, super tweeter for highest frequencies. In RiPols i have used SEAS CA22RNY bass drivers /8" is smallest bass drivers which is OK for making RiPol subwoofer/. This is passive RiPol, even best way is made him active, for my using/plan, i decided go for this. Low pass filter is made with Mundorf and ClarityCap parts. No highest quality, but also no lowest. There is cca 360mikroF, and use for it high quality caps will be extremly costly  :P Btw, for low pass filter i think, is good enough. As super tweeter i have used HiVi RT2CA drivers. Fileterd ust with Jensen Audio Alumen cap. Here i used high quality cap, here it´s very important. Tweeter and Davis wide range drivers is regulated by attenuators. We are humans, have different rooms and devices, like this i can setup their character much better for each situation. Everything is fully open baffle. Even Davis isn´t designed for OB, even alone, he can play very well. RiPol is passed on 170Hz. Tweeter on 9000Hz. Impedance for single wiring is between 2,5-3ohm, and impedance in bi wiring is 4+5ohms +/-1ohm. Little bit low, but good amp can easy drive it. I drive them with Crayon CFA1.2, and everything is perfect. Sensitivity is around 91-92db totaly. Body is made from beech multiplex, thick 25mm. On the top is natural veneer, two different wood, and painted with wax oil, 3 layers. Internal cabeling is made with AdamHall 2x2,2mm twisted wires in cotton insulation, and used real gold plated pins where been i can´t solder it. Rest is made wire by wire, soldered with silver WTB tin. Sound? Is hard to explane, but what i can say - the background is completely black, quiet, the bass is deep, tight and fast, it can't compete with anything even with large closed speakers. The sound comes from space, and I can distinguish not only the left-right or front-back effect. But also height positions and positions are "visible". The tonality is more than very natural, pleasant, realistic to the point that I sometimes get scared when something unexpectedly plays or a human voice is heard in the background.
   I hope, you will can like my design and work as well. I try my best, even i went ower any my limits and possibility in my small workshop, with just hand tools  [smiley=10.gif]  Thanks for watching  ;)

Wow! Incredible!

I'm trying to wrap my head around how it all works, the open baffle subs are pretty cool.

Great workmanship.
