Thank you for commenting. It's true that specifications aren't everything, and it's not possible to know exactly how a system will sound just by looking at numbers.
The higher-end models look nice, so I'll limit my comments to the Media Desk. It seems that such a small set, even with sealed enclosures and nice drivers, will still have frequency reproduction problems. A crossover frequency of 110 Hz is high enough that the subwoofer will be playing directional frequencies. The threshold of directionality is roughly 100 Hz, and given that the low-pass filter is set to 110 Hz, even higher frequencies will be played as the filter slopes downward. The satellites' nominal operation frequencies are between 300 Hz - 10 kHz. Above and below that, they begin to roll off. The subwoofer begins to roll off at 35 Hz. In other words, the speakers are not full-range.
I love smaller 2.1 systems for computer areas, and I've owned and heard a fair number of them. But in my experience, none of them were accurate. However, most of them still managed to sound good, just as I'm sure many people find the Media Desk to sound great.
This isn't my thread, so I apologize to the OP and others for the slightly off-topic post.
A few more comments:
The SATs "nominal operation frequencies" are not 300 Hz - 10 kHz. The operating frequency range is 110 to 20 kHz (+/- 3.0dB) as you can see here.
The SUB is sealed and does begin to roll-off at 35Hz, at 12dB per octave, which is much better than any traditional near field monitor, which is typically ported, rolls off at around 24dB per octave or greater and rarely do they touch 35Hz.
With regard to directionality: Directional acuity and the ability to locate the source of a sound, is much more complicated than just the crossover frequency. For this application, where the SUB is typically located very close to, or inbetween the SATs, directional acuity is going to be very low with regard to the SUB. This is especially true for a sealed box system, that has the subwoofer integrated into the design from the start. For more information about subwoofer directionality, please follow this link.
I hope this helps explain it a little better.
