Is it just me?

I can say that a lot of speakers that i have are best listened to with the grills in place and a lot of the speakers do not have removable grills because they are part of the voicing and an integral part of the sound.

Stereo5 shoot me a message if you ever want to sell that MA. I'll say nice things to make up for these inconsiderate bastards. 

I have bought several Porsche race cars and a Ruf Turbo without "looking under the hood." But there was provenance available on these vehicles, some of which were transported from thousands of miles away.

@speakermaster.  I think you are missing my point.Aside from electrostat or golden ear speakers which amount to a very small percentage of all speakers made,most all cone type speakers have removable grill covers.It matters not if the speaker sounds better with or without the grills in place.A person does not have to be tech savvy to remove a grill cover that comesoff in a matter of seconds.

@Jdane" I bought several cars without looking under the hood. What am I, as a non-mechanic, going to see there that I can evaluate? "
