Genelec 8341A spinorama and measurements

I doubt that's a good idea, as far as I noticed, Genelec used to use grills whenever possible to protect their drivers, wo when the Ones don't have it on the mid woofer must have some acoustic reasons to not do so.

Plus the exterior casing have continued the waveguide shaping, adding a cover must affect it somehow

Well in theory, an acoustically transparent fabric should basically be 'invisible' to the sound waves. Usually when a grill causes problems it's not because of the fabric itself, but because of the hard edges of the frame.

I suspect the reason the ones don't have a such a grille is that it would be hard to make it pretty, and Genelec probably assumes its drivers are generally 'tough enough' for most uses.

One of their greatest strengths is (imo) their ability to produce a tight(horizontally and vertically) center image while still maintaining fairly wide dispersion. They somehow manage to image almost image as tightly as JTRs, while also throwing a soundstage not much narrower than the Revels.

Is there a technical term for this? I suppose the other thing you are referring to is Apparent Source Width (ASW).

Well in theory, an acoustically transparent fabric should basically be 'invisible' to the sound waves.

I doubt it is when traversed at a very steep angle, which is why it wouldn't go very well with the waveguide; a horn would probably take it well. Plus, it doesn't really protect anything.

I'm betting it would look worst than this

I wonder how hard it would be to fashion a fabric grille to cover the 8341's waveguide. I feel like you could take just some acoustically transparent fabric with stretchy edges and stretch it over the woofer slots, like a glorified shower cap or something. That shouldn't cause too many acoustic problems, I think, and the woofers are mostly protected.

I don't see how fabric would add any protection at all though. The midrange isn't soft like a dome tweeter, it's more like a medium-hard rubber. To damage it, you'd need to poke it with a hard object pretty forcefully, or drop it in a way that there's impact directly on the rings.

I would not ship them without a board to protect the front driver. The carry bag for the 8040 is not to be used for the 8341. Instead they tell you get the very expensive hard case.

So you better plan on protecting the driver with even a taped on cardboard at the least if you plan on transporting them.
