Speakerlab 50's/Nesterovic Delta Hybrid 5's

i'm sure these are what he says they are, but i never heard of Nesterovic. in any case some pretty cool and substantial looking speakers.

I believe Nesterovic were rather more famous for their tube amp designs. Can´t find any info on them, though.

A little rich for my blood, nonetheless if only 25 pair were made, no wonder they're not so common...

No one knows about Nesterovic? Shame on you! One of the great speaker designers around. Smart smart dude. Builds nice amplifiers, but his speakers hav always been legendary. Doesnt change his product mix much, he just builds primo stuff. Expensive, but stuff you keep forever.

Nesterovic in this case is in reference to using two dissimilar bass drivers within the same cab. Something that is usually a no no but can be made to work. Seems SL like to use this method a lot. IMHO he is asking about $2000 to much.

thats pretty much what i figured, but i'd still love to hear them.
