Drowning in acronyms.......

[aussiephil]

To All

Yes there are a couple of very old threads that probably didn't need reviving.

Whilst i have been around audio and speaker building for nearly thirty years theres a bunch of acronyms that seem to be prolific but i could not find any references to them except to decode them by reading, some days it feels like i'm in the middle of The DaVinci Code.

Here's a list from just a couple of hours of reading, along with my understanding of each one.

MTM Mid-Tweeter-Mid
BMTB Bass-Mid-Tweeter-Bas
MMMT Mid-Mid-Mid-Tweeter
XO Cross-Over/Xover
LR Left Right???
TM
OB Open Baffle
T-TQWT
CLD Constant Layer Damped
Ported Bass Reflex Cab
TL Transmission Line
TH Tapped Horn
IB Infinite Baffle
QW / TL
BW Bandwidth
CSA
BLH Back Loaded Horn?
FLH Front Loaded Horn?
BR
WG
HE High Efficiency?

It would be excellent to help new people to have an acronym sticky.

LR Left Right or Linkwitz Riley
TM Tweeter-Mid
T-TQWT don't know the T, the rest is Tapered quarter wave tube
CLD Constrained Layer Damping
QW / TL quarter wave TL
CSA Cross Section Area
BR Bass Reflex
WG Wave Guide

Saw a cartoon once with a man wearing a T-shirt with the following on it.

SPA
(Society for the Prevention of Acronyms!)

and the old classic DNA (National Dyslexics Association)

My understanding in red...
Not sure what CSA is, did you mean CSD? Cummulative Spectral Decay?

[c2cthomas]

CSA = Confederate States of America??? Confederate States of America - Wikipedia, the free encyclopedia

Hmmmmm.......... probably not

Perhaps = Canadian Standards Association - used a lot to meet electrical safety standards in the frozen tundra....

Just to be technical. NONE of what you posted are acronyms.

NASA
LASER
RADAR
FUBAR

are.

[Darkstar52]

Would they be acrostics?

[Pano]

Almost! Oddly, I'm reading a book on the subject at the moment. (Mnemonics)

Made me laugh as by the majority of sources you are correct, however, Merriam-Webster, says that an acronym is just "a word formed from the initial letters of a multi-word name.

Whatever we call them they are often confusing to newer people to any hobby.

Thanks to those who have aready provided additional clarifications already.

Cheers

That is another one. Lots of TLAs have multiple meanings
