Factory Speaker Specs & Grilles
« on: December 02, 2015, 07:51:11 am »

Lots of research and effort goes into the design of cones & drivers & dsp correction & amplification to produce nice spec'ing pro loudspeakers, but then we clamp reflective 60% open-area (i.e. 40% blockage) metal grilles on everything. I imagine these cause measureable response aberrations.

Back in the audiophile era,  FR was often displayed grilles-on and grilles-off. Is there a manufacturers standard methodology when speakers are on the measurement turntable?

Jim, Who cares ?
The measurements better be as sold, as intended to be used. In other words, grills on. I don't really care what they will do hanging upside down, grills off, in a nudist park. That's not how they are usually used.
Audiophool and it's wizardry have very little correlation to live sound.

Yes, the grills do cause a number of different issues.

Part of it is a loss of HF-due to the direct blockage.

Another is the reflections off of the back of the grill-back into the speaker-and then causing combfiltering-due to the multiple arrivals.

Hopefully the spec sheet measurements are made with the grills on.

I was at one shootout a number of years ago and the other manufacturer actually took of the grills onsite to get more HF out of them.

That is not how they would be installed-but that is how they demoed them.  Not exactly the same thing

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. :)

I'd like to know what speakers do in a nudist park. Do they need to shed their grills too?

When I was kid we used to take the air cleaner off our car engine to make it faster...

I thought it was more like the Harley-Davidson crowd immediately taking off the mufflers and changing the exhaust pipes . . . .

Look even better if they let me paint them red or orange.
