Biased 4406 networks

[4313B]

There have been a few inquiries about biased 4406 networks.

I figured I'd post a few quick snapshots of my mini-monitors. They're fun.

New boxes for 18Ti components along with new boxes for their little 121A subs. There's a charge-coupled 4406 network in that 115H-1 hole. L-Pad knobs aren't installed until the boxes are finished. Piano black lacquer finish maybe.

Other stuff - tired L212, mainstay L96/4313B hybrid, 4435 components, LE14H-1. One project could be pairing the LE14H-1's up with the 2344A/2425H's in nice sized 3 cu ft boxes... Maybe someday. 250XPL's and surround sound Ti Series are probably first.

Nice show and tell!!! I like all those goodies!! I have 3 pairs of L20T'T3 floating around is it worth doing the CC for them??

I want to say it ran me something like $100 a pair to do new biased filters (I didn't reuse any stock parts but could have).

You know how everyone's own creations are... there is a built-in bias (no pun intended) and unless they really stink... I had to have some guys and gals listen to them that couldn't give a rat's ass about JBL and cared even less about biased anything, they just like good music, preferably live. We A/B'd stock 18Ti's and stock 4406's and the biased hybrids won hands down. It's like they're alive. Very nice for a "minimal" loudspeaker. It was worth it to me.

They really sound good as they are.

Yes, they certainly do.

I remember some circuits(crossover) of bias(charged) that I seen on this forum somewhere in my researching. In some of them I noticed there were more than one set of caps to be biased in the same system. Will "one" battery work for that, and would it not introduce a way for the different crossover functions to affect each other??? Or did I not pay enough attention to them when saw them?
