Your right Peranders,

Its not often we see a masterpiece from Fred,

Apparently he has an eye for craftsmanship and engineering excellence.

Uli has the idea of diffraction loss compensation crossed your mind??? Not that you have to design it in. But is the crossover you are designing mother board daughter board type idea that would allow the insertion of such a module. Then again the proper variable Q setting would provide almost the same thing.

To many ideas and not enough time.

Mark,

That is a very interesting topic.

In an earlier link to the L R site there is some great reading on diffraction effects and I expect those with dipoles in particular would benefit from this feature.

Another area for compensation is room boundary loading.

Hi folks,

A liitle disappointing answer at this time but all those nice little
gizmo features would blow the frame of this Sallen Key
implementation.

For baffle compensation you would need the electronic equivalent
of a LR combination.

Room compensation:

Maybe Mr. Pass will do a 5 band full parametric equalizer with
delay adjustments all in single ended class A somewhere in the
future ( )
For my part I tend to live with room loading as natural instruments
played live in this particular room are loaded in the same way.

Any news ?

Actually, since the MOX was posted over in Solid State, and
the basic circuit is virtually identical to the XVR1, and he has
made board artwork available, I figured that the pressure
should be off, and so I back-burnered it again. It will come out,
but not until I think of something better than I had.

There you go ...............

I know it will amuse you to know that I have 6 pigs (among other
animals) and they often wake me up in the morning rooting
around outside my window. Never thought I'd develop affection
for pigs.

Heh. That's par for the course. What other tasty tidbits are there to know? I've never imagined The One and Only to be in cahoots with ol' MacDonald.

As a guy who has spent a little time on a farm, I gain more and more respect for you daily!

Sandy !
