I thought it was more like the Harley-Davidson crowd immediately taking off the mufflers and changing the exhaust pipes . . . .
On many carbed cars of the 70's you could also flip the lid.  Pull the vac. hose off the ER valve and stick a golf tee in.  Crank up the timing a bit and put some bigger jets/metering rods in and you could really wake up a smog motor.

Or you could remove the valve on a small block Chevy and block it with a plate.

I think I'll pull the grills off of my cabinets. That way the crowd will have a target for throwing shit at, it will make it easier to punch holes in the cones while moving them, and if I still owned a cat it would make it much easier for it to piss on them.

Of course some speakers are easier to tear up with the grills removed than others---  ;)  ;)
In some cabinet the drivers are not easily accessible and are more protected.

Good points and if there was any chance of those things happening I wouldn't take the grills off either.
But mine are permanently flown and not in a bar.

Look even better if they let me paint them red or orange.
That's a matter of opinion John ;-)

I see some speaker grills that are honeycomb shaped holes and look like they provide the best open ratio.

Good timing. I just took the grills off my SH96HO's. Like an hour ago. Been meaning to do that for a while. Next shows on Friday and I'm expecting more hi end. I think they look better too. :)

If I did that to mine, I would have birds nesting in them. Then PETA on me for when the birds died after they were fired up.

I thought that too... Until I tried it out on CAD...



This is with a 6mm wide aperture and 2mm of material between apertures.

If I offset the apertures out by 0.5mm keeping the spacing the same (increasing the aperture width to 7mm and reducing the solid material to 1mm wide) I get 75.56% for both.

Interesting point. I don't see many, if any, square hole speaker grills.
It is my understanding that with a honeycomb, the strength of the design allows for thinner material between holes.
That would allow more open space per square inch.

You could always adjust the flat space that is the problem to be less flat and make it a triangle.  /\  So it will not bounce back as easily.   That would be a very costly grill !

When I designed the speaker grille for the bottom of my drum tuner, protection and effectiveness were both important.



At the frequencies I am dealing with the modest grille blockage was not an issue, and effectively transparent to the drumhead/speaker acoustic system. For my customer base (drummers) leaving the speakers exposed would be a bad idea.

Don't tune your drums half-ass. Listen to what a properly "cleared" drum sounds like.   http://circularscience.com/
