Dynaudio Emit M10 Review (bookshelf speaker)

[generg]

Happy to hear this...

I looked inside and when I am right, the woofer has only a coil means 6dB filter and the tweeter has a cap and a coil, so I suppose 12dB.
Normally the cooking book says that 6dB filters on both sides demand no polarity change, and 12dB on both units demand to switch polarity of one of the units.
So with this mixture of 6 and 12dB, the phase correspondence might be not so compelling for the one or other.
I seems Dynaudio decided for the way the speakers have a small valley around 1.4kHz. This makes more panorama.....
Or in Chinese production was a fault....
:--))

Do not know and I am no expert.

If the tweeter polarity is reversed, would the tweeter sound become 180 degrees out of phase/upside down?

And if that's the case, should I switch around the tweeter orientation 180 degrees?

 

[Zaiden]

Yeah I just flipped my speaker upside down. The tweeter now sounds more correct, if that even makes sense.

I think I'll drill new holes to screw in the tweeter in a 180 degree orientation from its previous spot.

The more open midrange/brighter sound is definitely welcome. But I was getting bugged by something and I think this was it.

 

[Zaiden]

Okay, I flipped the reversed polarity tweeter upside down. Drilled new holes into the Dynaudio Emit M10 for the tweeter.

Holy smokes. This is it. No more feeling bugged. Perfectly balanced frequency response, without this weird sense of the treble output being upside down.

And it's retained the previous desired change, essentially becoming a midrange focused speaker, with airier top end, while still having a lush, colourful bass that isn't overriding the frequency response anymore.

As someone who loves their vocals/midrange, this is definitely a huge huge upgrade on how the speakers were before, where the vocals/midrange was being subdued by the V shape.

Ha, ha, funny idea!
If you like it more this way, why not.
I know too less about beaming and waterfall pattern.
Normally I would say the way the tweeter is mounted is not important.

The way I'd describe it is that the top end of the treble shared a dispersion area similar to the upper end of the woofer, and the sound could get raspy at times like the treble/mid and upper bass were crunching a bit.

Flipping the tweeter 180 degrees resolved that.

I own those speakers and I would say if you can get them on the cheap they are really good, better than anything for $400. But if you have $800 and that's their list price, there are plenty of better options.

this is probably a dumbass question, but i would like to know the answer anyway.

in theory for a speaker like this that does not measure well, would it be even worse in performance if the amp powering it also did not measure well?

Loudspeaker non linearity can be split into a few categories. One is linear distortion, where at a given point in space, the speaker is creating certain frequencies too loud or quiet. Another is non-linear distortion, where the speaker is creating signals which are not in the original, generally due to the mechanical limitations of the drivers. The last is directivity, where the speaker is creating a non-optimal sound field in three dimensions, with sound in certain locations having significant non-linearity not in other locations. All speakers are non-linear with regard to space, but the goal is for the sound quality to transition smoothly from one point to the next.

Amplifiers can have linear distortion, but it's almost never that significant. Maybe a single db down at frequency extremes, nothing like the linear distortion of any speaker. Amplifiers can also have harmonic distortion, but again, generally far less than any transducer. In addition, harmonic distortion rarely diminishes sound quality. For the last category, directivity, amplifiers have no impact.

as an m10 user i am interested if anyone knows if the issues raised in this review were resolved in the later "emit10" model?

since reading the review it has given me a case of upgraditis
