Ohm Walsh Micro Talls: who's actually heard 'em?

Ok, it may not be a cross-over exactly, but there are some electronics attached to the input board and there is switch and some capacitors. I have a photo if anyone is interested.

My TV related speaker hum ended up being a bad set of RCA cables between the cable box and the preamp.

After talking to the cable TV repairman, he told me that digital cable doesn't cause any hum and that was only an issue back in the analog days. Hey, what do I know?

In addition to the crossover electronics. Which should be pretty simple I think there is also what is called the "sub bass activator" circuit which is used to help extend the bass.  I'm assuming the latest x000 models still use that.   Js would know.  It's a circuit sold as an upgrade to older models as well.  I bought a pair when I refurbed my old Ohm Ls. 

Mapman,
Yes, that is probably what it is.
Thanks!

crossover most likelycontained in teh can with the drivers.

SBA can work off the full range signal feed into the can.

With my 5 series 3 drivers on the OHM F cabinets, everything was in the can as best I recall from when I first connected those.
