'Mirrored Speakers' apparently

Talking to a mate last night, he mentioned 'mirrored speakers'.

He'd been talking to a composer and had explained to him that speakers are never the same. on a mirrored set apparently they're dried at the same speed, same temps, and theres a whole lot more standardisation that goes into the building.

Anyone know anything about them?

Have you noticed much difference with top audiophile speakers?
No doubt there different but they are tested and pick the 2 most similar.

true..

my argument to him was buy a set of nice headphones. as his room is tiled, his PC is in the corner and the walls are pretty much bare, meaning REVERB!

id be less worried about slight speaker variation in his digital music creation and more worried about reverb, yes? headphones?

Sounds like a "matched pair",

much the same as matching output stage vacuum tubes.

It takes time and testing equipment to do it really well,

also the speakers will be more sensitive (transparent) than generic speakers.

Yes, definitely HP's in that situation

I`d ask your mate whether the "Composer" had his hand on your mate`s inner thigh whilst he was telling him the story about "mirrored speakers".

My understanding (along with Polk Audio`s, and many others) has nothing to do with the manufacturing process of the actual driver, but solely with the placement of the driver in the cabinet. Imagine, if you will, a vertical center-line running down your cabinet. Now, if all your components (tweeters, mids, sub woofers) are centered on this line, well, in essence, you have a mirrored pair. It makes no difference which cabinet your place on your Left or Right Channel

But, if your components are off-set - ie, to the left or right of the center line of your cabinet, one of two things will be obvious. Both cabinet layouts will be identical(A) - Not mirrored. Or the Left cabinet will be a mirror image of the right cabinet (B) - Mirrored.

With system (A) you can inter-change the cabinets from Left Channel position (physically) or Right Channel position and not realistically notice any sonic differences.

With system (B), the crossovers, in better quality systems, will compensate for the relative small difference in placement (from the center-line) of the drivers and as such, the cabinets will be labeled Left and Right and should be wired and placed accordingly.

Well, that`s my take on it.

Tjank you phate666 .

Whether thats what he meant, or its what GlennsPref meant, im still gonna be kicking his ass till he decides headphones over speakers for this.

How is he working? If he is producing music straight out of the computer, he should alter his setup because headphones wont suffice for mixing anyway. If he is composing and making scores for other musicians to play, it might not matter what he uses. I live with a professional composer who uses $30 computer speakers. All his output is sheet music so he just listens to get a general idea of sound, but doesnt need to mix.

basically hes doing an Electronic Music Production course and seems to be getting his whiney asian ass all excited over it, lol.

So yeah hes actually mixing\composing.

Please explain why headphones wont cut for mixing? I knew a composer who uses headphones and as a DJ i mix with headphones all the time.

do explain :D

They are no good for mixing because the right ear doesnt receive information from the left speaker and vice versa, and there is no interaction between left and right channels. Therefore you get no phase information and you cannot accurately judge how sounds affect each other, or how you will perceive them, in a stereo field. When people mix using headphones, reverbs often end up being too smooth and too long, and mixes are not very spatial. Some people mix ok with them, most dont.

interesting.

and you have a point.

I guess he'll have to just get some high end consumer speakers and headphones. and a carpet :P

Given most speakers are built in production runs or batches, there's unlikely to be significant variations in the construction of two speakers in the same set.

Especially if they are a symmetrical design like phate666 is describing.

The manufacturer will build cabinets for a bunch of speakers and they'll probably all go through similar steps on the same days, so temperature, drying time etc. will not be that different.

I'm sure it's a marketable phrase that many people will be convinced by. If unsure simply swap your left and right speakers and do a blind test. I'd imagine that room set-up will make any manufacturing variations close to impossible to detect.

Active monitors would be a different aspect. Variations between two discrete amplifier components may result in different sounds, but any decent company would be electronically tuning their amplifier modules to get them all close enough to a design baseline that a human couldn't tell the difference.

A lot of studio monitors are matched and come with a test certificate.

As they should be. But i'm guessing the matching is mostly about electronics and good design, and less about construction timing.
