Here are some measurements of the Mackie CR4 powered speaker.

The retail price was ~120 USD / pair. It has been discontinued and replaced by CR4-X.


My measurements are quasi-anechoic, with near-field port+woofer measurements, corrected for baffle edge diffraction, combined with gated outdoor measurements at 1m distance (5ms window). I measured the "passive" speaker (the one without amplifier), connected to the "active" one (Not really active. It has a passive crossover).

From Mackie's official Youtube channel:

The new creative reference monitors deliver the studio quality performance that you expect from Mackie, in a
compact package that outperforms anything in it's class.

The CR series takes Mackie's 20 years of expertise in designing studio monitors, and packs it into a new smaller
format, that gives you accurate, articulate full-range sound in a package that can easily fit onto your workstation.

With 3 inch and 4 inch woofers, that pump out an amazing amount of deep, punchy bass, and silk dome tweeters
that deliver smooth, articulate highs.

The result is full-range sound with wide consistent dispersion, and well defined stereo imaging that goes beyond
anything that you'd expect from a speaker of this size.

These are true reference monitors, with the flat response and accurate imaging you need to mix your music, or
multimedia.

The CR series deliver sound the way it was intended to be heard, with clarity that only studio quality monitors

provide.



It almost sounds too good to be true.

The estimated in-room response is probably not that interesting since they are meant for "near-field" listening, but still, here it is, compared to the smaller CR3-X, measured by Erin:

Near-field:

Uneven woofer response and a tweeter peak at 1.6 kHz.

The 1.6 kHz peak matches the right Batman ear, and the woofer resonance at 6.6 kHz matches the dip in the quasi-anechoic measurement (cancellation).

Horizontal directivity:

0-90 degrees for comparison with Stereophile measurements:

Vertical directivity:

Distortion:

Mackie CR4 THD 86 dB 1m percent.png



Mackie CR4 THD 90dB 1m.png



Mackie CR4 THD 90dB 1m percent.png



The port was already making alot of noise at 90 dB, so I didn't measure at higher SPL.


So, did Mackie deliver on the promises?

It's a very inexpensive speaker, so I'm trying not to be too harsh, but it sounds pretty bad.

Female voices have a tendency to resonate/distort, sounding almost like an old telephone at times, and the bass is muddy.

They did deliver on one promise though. The horizontal dispersion is even, and the horizontal ERDI looks good:

My advice for anyone considering using it as a studio monitor, is to run away, like the guy on the speaker. ;)

Thanks for the measurements! Keep it up.

This speaker is really not good and I dont think an EQ will fix it but it may help. I would not use this speaker for monitoring.
The on axis shows very steep up and down and I didn't let the EQ compensate for them and limited Q to 3.
We see some nice improvements with EQ but end of the day, still not great.

Another way to look at the same EQ is via a radar plot which shows with and without EQ.

Comparing with the CR3-X measured by Erin, we see it is a family disaster:

Any chance you could measure CSD and IMD? I guess the former you can extract from the measurements you've taken already

CSD-data would not be accurate with my setup, but thanks for the suggestion about IMD.

Here's a simple test, using 100 Hz + 1 kHz.

2-way speakers always have a hard time with this, and I know the comparison is unfair, but I'm using Revel F208 as a reference since I know it has low distortion, and I want to make sure there's no problem with the measurement (clipping).

Anyway, here's the F208 at 76 dB SPL, 1m (86 dB @ 30cm).

The highest distortion peak is at 300 Hz (below 50 is just room noise), and it's 62 dB below the 1 kHz fundamental (0.08% distortion):

F208 imd 100 1000 76db 1m.png



Mackie CR4:

The 1.1 kHz overtone is 33.4 dB below the 1 kHz fundamental (2.14% distortion).

Mackie CR4 IMD 100 1000 76dB 1m.png



F208, 86 dB SPL @ 1m:

0.16% distortion.

F208 imd 100 1000 86db 1m.png



Mackie CR4, 86 dB SPL @ 1m:

6.24% distortion. :)

Mackie CR4 IMD 100 1000 Hz 86db 1m.png




With F208, you could hear two clean tones. The CR4 sounded like a church organ. ;)


26,75 times more distortion at 76 dB / 1m.
39x at 86 dB / 1m.

Here is my take on the EQ.
Please report your findings, positive or negative!

For the score rational your journey starts here
Explanation for the sub score
The following EQs are “anechoic” EQs to get the speaker right before room integration.
If you able to implement these EQs you must add EQ at LF for room integration, that is usually not optional… see hints there.

The raw data with corrected ER and PIR:

Score no EQ: 2.4
With Sub: 5.2

Spinorama with no EQ:
Mackie CR4 No EQ Spinorama.png


EQ design:

I have generated two EQs. The APO config files are attached.
  • The first one, labelled, LW is targeted at making the LW flat
  • The second, labelled Score, starts with the first one and adds the score as an optimization variable.
  • The EQs are designed in the context of regular stereo use i.e. domestic environment, no warranty is provided for a near field use in a studio environment although the LW might be better suited for this purpose.
  • Large difference in loudness needs adjusting when A/B
Score EQ LW: 5.1
with sub: 7.7

Score EQ Score: 5.8
with sub: 8.4

You get what you pay for...
 
Great data set. Waste of time of a speaker. With uneven fr and high distortion it truly wastes the time dedicated to listening and adds fog and dust to any recording. A real pass in my book.
 
But the main question is - how do you get the like "Listening window" and "Sound power" in REW? Calculate in VituixCAD and reimport? Did I miss something?
 
Great job, Ageve. Weird Al's Doppelganger has a Klippel! Who knew?

Nope, no Klippel. Just quasi-anechoic measurements. ;)

But the main question is - how do you get the like "Listening window" and "Sound power" in REW? Calculate in VituixCAD and reimport? Did I miss something?

When you have a full spin in VituixCAD (generated using the merger tool), you can select File, Export, CTA-2034-A data. Select txt-format, and then import it in REW.
 
Great job, @Ageve!

Lol ..
I have a pair of MR-5's being fed by a pre-amp from my Rhodes piano.

I expect they aren't much better - but they do the job as an amp speaker combo for the Rhodes.

That being said, I've currently got a pair of KRK-VXT 4's not in use - and I may add a small sub and use them instead.
I'm always hunting down an old Leslie going cheap -- but the last one (825) I had was pretty dark and lost a lot of the top end of the Rhodes. Of course any Leslie is going to be pretty coloured.. but that's the point.

More like running away from the speakers :)

It can't be so hard to make decent multimedia speakers. The production volumes are large so development cost per unit isn't too high even when engineering something not broken.

There's probably not enough money to spend on an amplifier + decent drivers and cabinets at that price. The updated "X" version is just as bad (comparison by pierre above):

And then there's the M-Audio BX3. Similar price, and also really bad:

I had a pair of CR4, I found them interesting for the price, as computer speakers. I also bought another pair for a friend.
They have a design flaw, most of them produce no more sound no so late after warranty ending... I assume it's overheating issue.
This video gives an easy hack:
with limitation that then there's no more commutation between headphones and loudspeakers (by cutting a pin of the tda7265 amp)...
I also saw a video on how to modify the pcb and wiring to transform them in passive speakers...
I didn't have/take time to fix them.
Thus I reaaaally recommend to avoid them, many owners are very disappointed by such a low quality design, it's kind of typical example of planned obsolescence: cheap design which gives short product life (after max 4 years they are dead, even with limited usage).
