Why so few high end line arrays?


To me the intrinsic "wall of sound" of this design are compelling. I recently tried a very nice 3 way w/ stereo subs in my system after 2 years of line array-only listening and the lost impact and scale of eight midbasses/ribbons per side was profound. I was immediately aware of the music emerging from boxes, despite very nice imaging. And it's not that the arrays exaggerate the size of voices and instruments. Does the materials cost dissuade manufacturers? Is it the size? Seems like relatively unexplored territory in high end home audio.

Thanks for the response regarding higher impedance speakers. I currently use a Zero autoformer to raise my current 4 ohm speakers to 8 (anything higher than that and it didn't sound right)

Your system looks great as well.
Emailists:

Your system is impressive. You take your vinyl as seriously as I do my cds!

Headsnappin:

Have you heard the effect of comb filtering in more than one line array model designed for home audio? Can you elaborate on what I should be hearing (or not hearing) that is deleterious to the music? How would you compare/contrast it to the comb filtering of the much more commonplace MTM designs?
I am referring to these speakers.

I've heard several line arrays. Like any design they seem to do some things wonderfully, but also seem to have issues of their own to contend with and overcome. It's always a trade off for what you consider important.

In my experience and on the ones I've heard, they seem to have:
- very good dynamics, both micro and macro
- very good imaging and soundstaging
- however the image can tend to be overly large, like a 6 foot tall saxophone or a 3 foot wide nose on the singer

From what I understand the overly large image can be compensated for in the design of the crossover and speaker connections. I'm sure newer designs have done this.

It's also important to have proper amp matching, but this is true of any speaker.
