Accurate vs Musical


What is the basis for buying an "accurate" speaker over a "musical" one? I am very familiar with most audiophile jargon but this is one that confuses me. Musical to me means that the speakers convey the "air" or/and overtone of instruments.

"Accurate" on the other hand is what, the accuracy of a single note? If accurate does not convey the space of an instrument, how can it be defined as accurate? I can understand why an "accurate" speaker can be used in a recording studio or as a studio monitor but for casual listening/auditioning?

Thiel is an accurate speaker but Magnepan is more musical so which would truly be more faithful to the original source? Someone please clear this up for me. Thanks.

Musical describes the speakers you like best. Accurate is what you call them when defending your choice.
Gregm,

I see your point. My choice of words were not the best. What I meant was a speaker that has a ruler flat FR, limited distortion, and reproduces all the details but does not have the fluidity or emotion that a musical speaker has. I am not a speaker engineer so if it is "non-linear" distortion that evokes the terms i use then so be it. :)

Cheers
Thank you for all of the well informed intelligent answers. Audiophiles on Audiogon Rule!
The term accurate speakers is surely an oxymoron.No speaker I have heard ever captures the scale and dynamics of the real thing.So how can it be accurate?
The only speakers that come close to real world dynamics are horns and they usually have flaws in other areas such as phasing.
Many dynamic speaker owners claim that their speakers are accurate but if these people have use of a good pair of electrostats for a couple of weeks and and then return to their speakers they will usually be amazed by the box and cone colourations of their speakers.
Most of us get used to a certain sound and then come to believe this is accurate.Any similar sounding speakers we also label accurate.So it is a silly term and completely subjective.Their are also cultural biases involved.
