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

Almarg is correct; shoving a highly resolving system's signal through the electronic nightmare that was an Audio Control 101 to achieve flat response at the listening seat is an error. It would also ruin the sound due to the sheer amount of electronics, though they worked fine for mid/lo-fi systems. I sold those things 20 years ago from a store 4 blocks from the Lynnwood, WA factory, and sold LOTS of their excellent car gear, electronic crossovers and EQs alike.

In-room response is absolutely desirable. What I cannot abide are speakers with messy FR and dispersion curves as that can only worsen in-room FR.

For a simple test done by a fine Brit manufacturer showing the superiority of active vs. passive crossovers, see http://avihifi.blogspot.com/2010_03_01_archive.html . Of course, that is just one aspect; the amplifiers needed to drive drivers directly don't need a lot of current, so are far cheaper, smaller, and easier to make.

Martykl, there is never anything to be traded away by using electronic crossovers. I don't know why you think that. There are only strong advantages. There is no credible debate over the statement that it is always desirable to reduce speaker distortion. Passive crossovers produce several hundreds of times more distortion than a good electronic crossover. It is *always* desirable to remove that distortion from the signal.

The more important factors are speaker-room interaction, which affect the signal endlessly more than getting a new amplifier, new cables, etc., and general speaker quality--as in a better active speaker!

I can say with confidence that that the OHMs should rate very well in this aspect.

Tvad, it's difficult, and requires more sophisticated measuring techniques involving measurements from many places in the room. See Lyngdorf's website for how they recommend doing it with their digital room correction system. Which is difficult in and of itself.

It is indeed impossible to get accurate results out of Radio Shack gear. Plus, I'm not beholden to the artifices of pin-sharp imaging and stereoscopy, which don't exist anywhere in real life to the extent it can on some systems. It's why I don't really bother with room correction or damping; I optimize speaker positioning and go directly to enjoying music. I'm far less interested in tweaking about than I used to--I'm a red giant in astronomical terms, at the end of my long audiophile life.
