Not sure I've ever seen this before.

OK, so we all know the fewest 'most reasonably achievable' parts number for a 3-way crossover is Eight - 2 on the woofer, 4 on the mid, and a couple on the tweeter.  Thing is, has anybody actually done it?  I've never seen one before.  I'm messing around with one right now that fits the bill - no resistors at all.  Usher 8955A/Rival R176/CSS L22.  Just about every other 3-way has taken anywhere from 12-16 parts per side, including 4-6 resistors. 

Discuss.

No resistors? I've only seen that one other time and that was on a high end commercial product. It sounded very good. The name escapes me, but I think they cost as much as my house.

My recent 2way I thought was doing good with 9 parts, 3 of those resistors lol

I know a guy who knows a guy.

I could have done sans resistors with a corner loaded application in mind.

How about Keith's coax he's taking to Indy, 30 parts per side.

Yeesh! That 10" 2way is only using 9!

My 3-way coax ended up with 3 caps, 3 inductors, and 4 resistors, but I've planned it for off axis listening.

I managed to build the Allisons without any resistors. 24db/oct with 8 parts. I believe the Neo3 has 92db efficiency so they were pretty loud. Sometimes you get lucky. The little 3-ways I brought to Grinnell had 18 parts.
