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.

Darkmoebius,

You are correct. You have to design line arrays carefully to take into account lobbing and nulls. They work very well when properly designed and will ensure a higher SPL reaches further out into the audience at a sports or rock arena event.
I too had been advised of all the combing when I started considering line sources, but physics aside, my ears tell me something else.

I had a chance to hear a used pair of Scaena 3.2's today that were for sale. I have heard the 3.2 in various versions and systems over the past 2.5 years, so I am familiar with how it performs. In this particular demo, it was not setup anywhere close to ideally, since the speakers had just come into the dealer the day before, and there was alot of other gear around. However they didn't have a problem with me tweaking the placement and crossover levels, so I was able to coax a reasonable performance from them, even though no attempt had yet been made to pair them with best match of cables and amps in the store.

That being said, it was the best demo I have ever heard in that store by a significant margin, and that has included Magico V3's, Rockport Mira's various wilsons, Martin Logan CLX, etc. Now to be fair, none of those demos were what I'd consider proper set ups either, but I believe one can tell the basic character of a speaker, even in marginal setups such as these.

I'm not saying the Scaena is the typical line array, in that its almost baffleless design is rather cutting edge, but to my ear it what no other speaker in that showroom had ever done, and made me think that this was a product I could own for a long time. The level of detail, purity, and imaging achieved a level of realism that put them over the top for me. Plus the ability to listen from mid field and far field I thought was fantastic since they drop half of what point sources do over distance. And I didn't feel that instrument size was being overblown.

As I mentioned I am getting in some line sources to audition soon, where the drivers are positioned even closer together than the Scaena. I believe that this actually helps with combing, the closer the drivers are to each other.
Hi, I am very interested in the line array, especially when listening to them outside. 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)
