If you are looking for audio that you can sense, feel, if you are in the market for tactile sound, then we suggest that you take a look at this speaker system.

Remember 400 watts is peak power, which means if you run it at this for an extended period of time, you can risk burning out your speakers.

As always, when you look at speakers, pay more attention to the RMS. In this case, this system has a nice, powerful, RMS of 200 watts, and that is more than enough.


Each of the satellite speakers are 7.8 by 5.6 by 5.4 inches, so they will take up a bit of space on your desk, with each satellite speaker is designed with an angled shape which reaches upward, wider at the bottom narrower at the top.

The right speaker has three control knobs: Power, volume and bass. It has front firing, 2.5 inch, sealed drivers which drive the bass forward.

The surround is a soft butyl rubber, and the back of the drivers are magnetically shielded, stamped steel basket, large magnet, and a paper cone.

Overall, there are two 3.5mm connections, a headphone jack and an AUX input also are present on the panel of the right speaker.

What’s nice about this approach, using your satellite speakers for players and other devices, is that you can save yourself some computer memory, especially if you are working on memory intensive software programs, or gaming.

This way, no need to use up valuable computer power to play the audio you crave.

For an added tip, when you decide to use headphones, please check to make sure that your volume is turned down low before you hook up your headphones to your ears.

To not do this means that you can risk permanent damage to your hearing apparatus. You can always turn the volume down afterwards.
