Given that this system has been produced with rather mild specifications, I'm not predicting any window shattering sound pressure or earth shattering bass. However, for many smaller single user environments this could be more than ample, so let's see how they performed.
The High End
This system comes equipped with tweeters built in to handle the high end, which is definitely a good start. Unfortunately the tweeters chosen here are of quite a low quality and as such their performance is also quite limited.
Testing a mixture of different music, the high end sounded rather tinny at best and did not really convey any of the subtleties of the music being played. Technically speaking, I don't think these tweeters would really be able to extend past 12-15 KHz; not with any clarity and definition anyway.
The Arion ET-AR504LR-BK comes with two small lightweight 3" speaker drivers to handle the mid range frequencies. I believe these drivers are constructed from paper which helps with cost and rigidity.
During performance testing I found the midrange to be quite acceptable when listening to frequencies in the 1-5KHz range; vocals particularly. While using a rather high crossover between these drivers, the subwoofer limits mid bass a little. But it has certainly aided in providing quite clean mid frequencies, if perhaps a little lacking in the 300Hz-1KHz area.
The Arion's low end is provided by a 5 1/4" woofer located in what appears to be a side firing band pass enclosure.
What I mean by band pass is that the woofer is located in a separate chamber inside the cabinet with the addition of a side firing bass port. Now, the 'benefit' of this sort of enclosure is that a certain narrow 'band' of bass frequencies are exaggerated while others get totally neglected, meaning that the 80Hz-200Hz range is boosted but anything under 80Hz bass drops off to nothing.
During testing I found this subwoofer to be about on par with most other small cabinets. Generally speaking you will get a small window of bass that is always thumping away (around 150Hz), but really not much aside from that.
On the upside these subwoofers are great for people in apartments or small noise restricted areas.
