Here is the software
A, B, C, Dipole

Very useful. it allows you to model the response and create active crossovers.
I went through the design process a while back. I developed the active crossover design and then modelled them and converted them to a passive crossover.
I was already to attack it but then I got heavily into riding motorbikes and went MIA.
Anyway the original plan has changed now. So I will need to start from the beginning again.
I know exactly what I want, and I think I will get it, I just hope this full range speaker is good.
I am starting to think I might put a 1st order High Pass filter on it. Although the manufacturer reckons it is OK for open baffle I don't like that Xmax is 1mm.
Anyway I don't really need it for bass duties anyway. I've got that covered.
Just hope it sounds great. If it has great midrange and treble then I will be happy.

They are absolutely bloody beautiful. Even if they sounded crap (and I know they don't) I would be happy to have them in my lounge room just to look at them.
Best looking DIY speakers I have ever seen. I reckon they might even look better than what I have been working on.

How come you did not go Open Baffle all the way?
Was it too hard to maintain the efficiency and frequency response you wanted?

I still prefer TL bass ; in any case , one of conditions was not-biamping ;
in any case - entire xover is one coil , one cap ; no stinkin' attenuating parts



I made some sims for Sonido 8" FR + 2x Eminence Alpha15 per side , and pair of them was made and everyone was happy

look here : http://tinyurl.com/d4ectwe

either use Chrome translator , or Google one

Papa, seems like we will have the new active audio device coming:

The return of the vacuum tube?

Gotta contact NASA to produce some samples for you (and the DIY crowd)

I remember seeing these and almost buying a pair because i liked the look so much. I also liked that they offered both a FR unit and woofer. I might buy either the LCao or SOnido after GB when i get some time. Specially now I got cheat sheet1
