message: Would this be the place to have an entry for a line array and point source? or should those be entirely different articles?
:You could put them here to begin with.  If the article gets too big, someone will move them to their own articles later. --Heron 07:56, 9 Sep 2004 (UTC)
thread_title:  Line versus point sources? 

message: I believe that it would be a good idea to split the article because although enclosures are part of a loudspeaker, they also are a componant of their own, and it diserves its own article. I have already setup a Subwoofer enclosure Loudspeaker enclosure article and linked about 10 articles there, and then redirected it to Loudspeaker for now. Please comment:
:Well, IMHO all enclosures except the band-pass, PR, and dipole are used in non-subwoofer applications also. So if it is split, it would be better to include all enclosures in the article and name it "Loudspeaker enclosures" instead of "Subwoofer enclosure", indicating in the article the common application of each enclosure (i.e. general purpose/bookshelf/subwoofer/etc).

replies: text:  Ok, Thats a good idea, Loudspeaker enclosure would be a better name. So do you agree that it should be split if it goes to Loudspeak enclosure? Fosnez 10:28, 10 March 2006 (UTC)
replies: text: Well apart from a small change to the name to "Loudspeaker enclosures", I have no issues. However, you may want to get a few more opinions before proceeding. Rohitbd 10:46, 10 March 2006 (UTC)

thread_title: Split [[Loudspeaker#Enclosures|Enclosures]] section to [[Loudspeaker enclosure]]

message: I am currently a media production student studying 3D design as part of my solid modelling module. I am trying to design a futuristic (25 year gap) speaker. Having hunted there appears to be little 
about the future design of speaker casing most searches have led to dead ends............... can anyone please offer a resultant target?
:Hehe, I think in 25 year's time, loudspeakers won't resemble anything we know today and will most likely not require enclosures as we know them. Speculations on future LS design hint at excitation of air molecules without physical diaphrams, much like plasma modulators. Who knows, maybe when we get a grip on the invisible forces surrounding us, we can coax the air molecules to mirror the exact recorded perfomance without our current relatively crude actuators!
:Model a small orb with a slight indentation on the top and call it "The Acoustic Exciter" ;)

message: Is it just me, or do those two sketches in the enclosure section tend to come and go randomly on random days? today i can see the first one and not the second one, which is a new phenomenon. Gzuckier 03:18, 9 May 2005 (UTC)
thread_title:  what's with the enclosure sketches? 

message: I added a little note at the end of subwoofers re: the LFE channel on modern decoders since there is often confusion about its purpose.  I'll edit the LFE page later to be more informative instead of blathering about it where its not relevant. MtB
:Thanks for that improvement!
:Don't forget to sign your notes on "talk" pages (I've done it for you). You can easily include your signature and a timestamp simply by ending your note with ~~~~ (four tildes); that will be replaced by a hyperlink to your Wiki username and the current timestamp.

thread_title:  LFE vs. bass management 

message: I removed this aside from the text, as it didn't help to explain how plasma speakers work.
:(the electron, which carries the charge in an electrical current, is defined as a negative charge only because the repulsion of positively charged candle flames from a positively charged electrode and towards a negative charge was misunderstood as the flame being blown by a flow of charge carriers from one electrode, which was therefore labeled as positive, needlessly complicating the life of beginning engineering students). 
It might belong somewhere in Wikipedia, if it's true. --Heron 18:35, 11 July 2005 (UTC)
thread_title:  Charged flames 

message: This article should include a section on series vs parallel speaker connections. I am trying to figure out the difference, and how those connections are set up, and cannot seem to find a simple explanation.
:Howzabout this as a start for your thinking:
:Speakers can be connected in series, parallel, or series-parallel networks. When connected in series, their impedances are generally additive. When connected in parallel, their impedances are generally described by the formula
::
{1 \over { {1 \over Z_{1}} + {1 \over Z_{2}} + \cdots + {1 \over Z_{n}} } }
:(as with parallel resistors). This change in impedance with either a series  or parallel connection may affect the performance of the speakers, the amplifier, or both. When connected in series, there may not be sufficient voltage from the amplifier to drive the speakers to produce an adequate volume. When connected in parallel, the speakers may impose too great a current load on the amplifier, leading to the amp overheating or simply shutting down. Because of this, the use of speakers in series or parallel circuits must be carefully evaluated.
:A common solution to this problem in large installations is the use of Constant Voltage Circuits. (And I think these are described elsewhere in the article.)

thread_title: Excessive list of links

message: Note also that there is lots of wiggle room.  What you have cited is a guideline, something we are free to ignore, not a policy. Gene Nygaard
*If the argument is that the guideline should be ignored, please explain why it is benificial to do so.  Referencing sections of some of these would be helpful:
**Wikipedia:Policies and guidelines and  it's talk page, 
**Wikipedia:What Wikipedia is not with the risk of embarrassing myself,
**Wikipedia:External links itself, and
**Wikipedia_talk:WikiProject_Albums#Links_to_reviews has a similar theme.

thread_title: Arguments for ignoring the guideline

message: Having read the article I think its very much in need of a few changes, none more important than deciding on the terminology to be used to refer to a driver (transducer) and to 1 or more drivers in an enclosure (cabinet) and clear distinctions to be drawn between the 2. I also think the last 1/3rd - 2/3rds of the article could benefit from being farmed off into other articles. Just my 2c but it is a very messy read. People seem to be actively editing so I'll leave well alone for fear of treading on others toes.--Pypex 23:46, 7 November 2005 (UTC)
thread_title: Article Cleanup

message: I did my best tryng to clean the article, check it out, I hope the work could be useful
:Why not split the Specifications section into two parts, one for Loudspeakers (complete system) and one for Drive Units or Transducers?
:Generally loudspeakers have a small set of specifications of interest to the normal user, while the drive units themselves would have substantially more. It would make more sense to break it apart to make the context clearer.
:Overall this article has poor focus and needs to approach the topic of loudspeakers from a general scope. The various types of loudspeakers in existance are too many to deal with in detail and should only be briefly described.
:Essentially a loudspeaker as a whole is an acoustic transducer, used to covert recorded material from its electrical waveform (in the case of analogue signals) to acoustic waveform. The basics of how this is achieved remains the same regardless of the method of excitation. Only once this has been properly detailed, could one present a general overview of some of the techniques/technologies employed to achieve the above.
:References could then be made to technical resources delving into the contriversial guts of LS design ;)

message: Much of this article seems to have been copied from http://www.audiocircuit.com (click 'Loudspeaker'). Njál 03:37, 24 January 2006 (UTC)
replies: text: You are mistaken. Before making this sort of accusation, a chicken vs. egg question should be considered.  Consider rather that this article may have been copied by the audiocircuit people.  Having looked at the audiocircuit article, there is content there that I know I personally added to the wikipedia article.  That means that audicircuit copied the wikipedia article.

message: I just skimmed the article and don't see any mention of "70 V" "constant voltage" distribution systems.  Is there an article about this? — Omegatron 02:57, 25 January 2006 (UTC)
thread_title:  "70 V" "constant voltage" systems 

message: Heron asks if this new sectionof the article is spam. I think I'd say that it is. Transmission line speakers ain't really nothin' new; horn-loaded speakers share a lot of the same attributes and it could be argued that they are also transmission line speakers. In any case, the recent editor certainly was pumping in the PoV. I think it would be correct to tone this section down squite a bit.
