This may sound like a dumb question but it's a question that has popped into my head for quite some time now... Whenever measuring speaker distances from the listening position, sidewall/back wall placement or even width placement, where are these speakers measured from, the back of the speaker (the rear ports affects the overall sonics) or the front of the speakers? I've always made the center line of my measurements from the front edge of the grill, directly centered of the drivers for front, back (sometimes) and side placement ... basically disregarding the 17 inches these speakers are deep (I have lot's of room behind the 80s) but I know many of y'all have your speakers 6 inches or so from the back wall, telling me you measure from the back of the speaker. Where do you all take your measurements from? And if most of y'all don't understand my question, it's no biggie ... I'm on my fourth Heineken so give me a break, it's just a beverage induced, mind boggling question.

Rick, I usually measure from the center of the front edge of the speaker.

When I measure the back wall distance I measure perindicular from the wall to the center of the back of the speaker box

For me:
Back - from the wall to the rear of the cabinet and normal to the cabinet.
To sweet spot - from the front baffle to the spot diagonally
Width - centre to centre

Rick, the relevant distance should be measured from the center of the woofer cone, also counting the distance traveled along the front and/or side of the enclosure.

If this is the case it looks like I need to measure my distances again. I have always measured from the back of the cabinet to the wall.

Yeah, Rick Wid; it's the point where the sound is actually coming from that interacts with the nearby room surfaces.

John, could you post a link to your source for this information. I just read this article that shows something different.

Well, sure it's different; it pretty much ignores the point raised in this thread, i.e., what part of the speaker is relevant for determining distances. The sound waves reflecting off the boundaries obviously start at the driver cone, not at some part of the enclosure. As far as the different distances to the boundaries requirement goes, here's one brief discussion I found quickly.

In the article you referenced,"Tips For Speaker Placement", the author states "placed...angled in toward the listeing seat." I have not receive my m-80s yet, but when I call Axiom, they said you do not need to toe in Axioms. What do most people do?
