kind of an inside joke I posted shortly after I set up my Home Theater

If you haven't heard the words, you don't have enough subbage yet. :D
Better and more sensitive than a standard SPL (Sound Pressure Monitor)
and somewhat related to WAF.

...my Spousal Pissedoff Measurement goes off every time
my system has exceeded her tolerance levels...
Furniture, glassware and pictures rattling on the upper level (two storey home)
when I'm all the way down in the basement mancave playing with my toys makes her Lose it!

TTFSD !!! gets yelled down
the open stairwell all the way down to the basement mancave, and its LOUD!

I first heard it go off about 8 years ago, shortly after moving into our new home.
Right from day one I was told the main floor was off limits to my AV gear,
but I was free to do what ever I wanted in the unfinished basement.

...well even that changed the first time the TTFSD alarm went off.

you don't have to add it to your list, it's more of a joke ;)

I have a pair of SubMersives. My guess is TURN THAT F+++ SUBWOOFER DOWN. Well, more of an educated hunch based on personal experience. :)

Added DEQ. I think it stands for Dynamic Equalization, and I think it is a marketing term for a feature offered by Audyssey.

But let me know if I got it right or wrong.

Essentially, altho Behringer also uses the same acronym for a feature in their gear, even part of the name of this unit. Similar to loudness contour as found on older 2ch receivers, for compensatation of specific frequencies based on the playback volume level....along the lines of a Fletcher-Munson curve.

Added Q, from SVS's Q control. Don't know what it is an acronym for (if any), and what means (if anything). Welcome suggestions.

Here. Your Xmax description in the list is wrong. Mine is correct.

I thought your definition and mine were quite similar. I got mine from http://www.subwoofer-builder.com/xmax.htm In either case I added yours above, before mine.

As to Q, I need a physics PhD to read that Wikipedia page. Any succinct explanation would be appreciated.

Thank you, Kool-Aid Man!

^^ The first paragraph there is about as succinct as it gets. It's a difficult concept to explain simply to non engineers. The pendulum example on wiki is good. I'd add the link and maybe this one too: Selectivity and Q of a circuit, mainly for the middle and lower graphics as people may have seen graphic and parametric EQ filter responses.

As for Xmax, the VC does not need to exit the gap. Xmax is usually defined by manufacturers in one of two ways: excursion when it reaches 10% THD, or in mechanical terms, Xmax= [(winding depth - magnetic gap depth)/2] + (magnetic gap depth/3).

For Xmech/Xlim, damage can happen in both directions where suspension such as spiders and surrounds are damaged on the outward stroke.

SME added.

Will work later on refining the definitions for XMAX, XLIM, and Q. If anyone wants to offer succinct explanations, I welcome that.


Thanks, this helps noobs (like me) :D
Glad that this helps - that is exactly why I created it. I too consider myself a noob.
Personally, I think this should be a sticky thread, but that is not my call to make.

Great idea, but why is it in the subwoofer forum?
:confused:

The ones that gave me a hard time (IIRC [if I recall correctly ;)]) often have nothing to do with audio/video, but I'm an old, non-texting, non-tweeting f*rt, so they may have been obvious to someone else:

BTW - by the way
OTOH - on the other hand
AFAIK - as far as I know
HST - having said that.

...because most of us are too lazy to type the entire movie title
TIH is just quicker to type than The Incredible Hulk.

If anyone here has been around from the start its a given that we know what movie is being referred to,
but to someone who just joined within the last year or two may not have a clue.

The subwoofer forum is where I spend the bulk of my time on AVS (because subwoofers are where its at), so that is where I came up with the bulk of these terms.

I don't think we need to include LOL, FYI, BTW, etc.
Keep focusing on audio/video directly related terms.
F3 should be on the list. It is a frequency in which sensitivity drops down 3dB.
MTM (midrange-tweeter-midrange), a typical design for HT center channel.
(I assume we all know HT means Home Theater).
Do we have to list HDMI, ARC?

Added ICE (for ICEpower). Does anyone know if ICE is an acronym?

Added JTR for JTR speakers. Does anyone know what JTR means?
