K3809 as main driver , K3833(K3836) as bass helper

K3809 are mine , while K3833(K3836) , stars of previous blog entries  are prepared for SuperFi’s Westminster project .

Just having fun with some old OB “wood” , gift from Chakija ( he’s not feeling young enough to continue playing with them 😉 )

Disclaimer – I really wasn’t expecting real bass ……. that’s max width I can squeeze in living room , where spks must be situated ; also , MJK OB software didn’t predicted it (bass)

But !! – there is bass , at least in my smallish living room ; sound is remarkable , even with crude and quick xover , without any efforts put in measurements and polishing of same ; OB is far from optimal in almost every area , but it is so fun …..

I had them for some short time , just to make vivisection , clean the switches ….

I was really surprised how plastic coned 2528 is good ……. 😉

Of course , as always with any new driver to me, I tried them baffle-less and I’m primarily basing my impression on that ; that was main reason why I , later , urged my Vladimir to try them , as cheap and easy way for trying Audiophile Retirement 😉

Data for coils :

As title sez – boxes for Mr. Vladimir Simovich’s (AKA AR2 , AKA Master Burner ) office 😉

Finally I got him to buy a pair of not so expensive Tanns ….. after more than a year of me harassing him with numerous Tann links …..

Box plan is sort of my job – done with MJK MathCad MLTL sheets – , while xover will be , hopefully , other Aleksandar’s work –

Mr. Simovich and Mr. Aleksandar Radisavljević RAAL are friends …. and these gorgeous Eternity pics at RAAL home page are work of Mr. Simovich 😉

So , world is ……. small
