Here are some measurements of Argon 6340, the smaller version of 6350, measured here:

Argon speakers are developed and sold by the Danish retail chain Hifi Klubben (founded by Peter Lyngdorf). This model was discontinued in 2018. The retail price was ~95 USD/pair (996 SEK).

They look similar, but the drivers are different (smaller tweeter as well).

Well, that's not good.

Early reflections are also worse compared to 6350:

0-90 degrees, for comparison with Stereophile measurements:

Vertical directivity:

Near-field response:

All the problems at 4 kHz seem to be caused by a woofer resonance. The huge port resonance at 1.5 kHz doesn't line up with the 2 kHz peak though, but maybe it's still causing it?

One positive thing is that the distortion is quite low:

But still, worse than the 6350:

I listened to it while writing this, and it's quite bad to be honest. The funny thing is that it sounds completely different from it's bigger brother.

At ~3m distance, the 6350 sounds neutral, but perhaps a bit dull / has a lack of detail. It's good considering the price though.

At the same distance, the 6340 sounds very bright and hollow, like it had built-in loudness.

I made this EQ preset based on the estimated in-room response (Graphic EQ plugin for Foobar 2000). It's not perfect, but it sounds much better (not suitable for near-field listening):

Yes, looking at the PIR and on-axis, it's pretty obvious the upper midrange / lower treble is going to sound noticeably bad on this one. Another good example of measurements where something has gone totally wrong. If the 1-5khz range was smoothed out, you could possibly forgive the rest. But I think it would probably sound really grating / nasal. Thanks for sharing!
 
Thanks for your measurements Ageve. Well done! :D

The two models, 6340 and 6350, look so similar. One might wonder what Argon's design philosophy is? :oops:

Could you remeasure with pluged port? From my point of view this port is a trouble maker at 100-200 and 1k to 2k.

Here it is.

Note: Measured in my living room. I was too lazy to add near-field bass, but it doesn't really matter for this comparison.

Hm... It made almost no difference, so the port wasn't the problem. It looks like just one measurement at > 2 kHz, but it's not. ;)

This is how the in-room measurement looks compared to the one from the spin data:

(Bass < 400Hz is from the original measurement since it doesn't really matter for this comparison):

To make sure the speaker isn't broken, I borrowed the other one today.

Here's a comparison:

(Both are in-room at 1m distance, 5ms window).

Note: I was once again lazy, and added the bass from sample 1 to both. It's getting late and I need to get some sleep. ;) Please ignore the lack of difference below 600 Hz, where I merged it for this comparison.

Hm... The difference at >4.5 kHz is probably just unit to unit variation, but there's a 3dB difference at 2.5 kHz, and the 4 kHz resonance doesn't look as bad on sample 2.

I switched back and forth between the two several times to make sure the measurements were accurate.

Could it just be poor quality control / pair matching, or is there something wrong with the first one?

I might have to do a spin on sample 2 as well, but not today. ;)

Thats strange. If i look at the port neasurements the influence should be bigger. But ok its like it is. Thx! And the influence could look like the other speaker??? Did you pluged the wrong speake?? Sry, but its so strange. :)

Sorry for replying a month too late, but the first speaker was measured with and without the port blocked before I borrowed the second one. :)

The difference at 2.5 kHz is a bit strange, but perhaps the kind of unit to unit variations that can be expected for the price. I didn't do a spin of the second speaker, but I did listen to both and they sounded very similar (i.e. not very good ;) ).
