quality speakers are excellently designed
How is the speaker clear?
Let me preface my review by saying that I am no "audiophile."  While I do have electrical engineering knowledge and understand many of the specs that can be compared amongst speaker sets, I cannot discern some of the subtle differences that true audio technicians can.  On the other hand, I am also picky about sound quality and am able to immediately notice many aspects of speaker design based on how they affect the sound of a song.With that said, my appraisal of the Klipsch Promedia 2.1 system is a 5-star rating.  These high-quality speakers are excellently designed, admirably built, and deliver outstanding sound quality whether they are used with music, movies, or video games.First off, the speakers themselves are wonderful.  Featuring strong midrange drivers and bright "horn style" tweeters (a Klipsch tradition), they deliver the full range of frequencies contained in a typical audio track.  In this regard they surpass competition such as Logitech, which lacks good midrange abilities.  The Klipsch speakers are good enough to draw out flaws in lower quality audio tracks, which can be mildly annoying, but is a great testimony to the quality of the drivers and filters.Now, the subwoofer.  I demand GOOD bass from my music.  I hate deafeningly loud, boomy bass units that obscure the higher frequencies and irritate everyone within a half mile radius.  On the other hand, weak bass drivers that rattle and vibrate or distort when the music is turned up are also an abomination.  The Klipsch subwoofer, which runs at 50 watts continuously and can peak at 130 watts, is perfect for in-home audio use.  While it probably would not be sufficient to overcome road noise in a car (I have a 150 watt subwoofer there), it is more than ample for a home theater system.  I absolutely love the sound of the bass from this thing; while it is ported, which generally makes for boomier bass, the Klipsch unit does deliver very tight, clean bass.  A former roommate who was arguably much more of an "audiophile" than myself even commented with approving surprise about the great resonance the sub has at low frequencies.  Again, this sub might appear to be weak at only 50 watts RMS, but it is MORE than sufficient.  If you turn up the volume loud enough to start distorting or rattling the subwoofer, you will be completely deafened by the satellites.Features are where the Klipsch speakers lose a few points from the overall rating...but not very many.  Like most computer speakers, they feature a decently lengthy input cord (1/8" [3.5mm] stereo mini-jack), headphone port, and volume adjustment on the primary satellite.In addition, three features stand out as especially nice.  First, there is an additional input port (female 1/8" [3.5mm] stereo mini-jack) which means you can play music and video games at the same time, for example.Next, the speakers are connected to the amplifier/subwoofer unit via detachable 2-wire speaker cords, NOT hardwired cords.  This means you have a lot of flexibility in the placement of the units; additionally, the included wires are very long.  If they aren't long enough, you could also solder an extra length of ordinary speaker wire to the amplifier end because they simply clip into place.  The satellite ends have 1/8" jacks on them which plug firmly into the back of the satellites.Lastly, the subwoofer can be fully adjusted via a knob on the primary satellite, meaning you can turn it down or even off without affecting the volume of the music.  This is great in apartments and dorms where the bass is OK during the day but must be toned down at night to avoid disturbing people.The one feature of the set that is NOT a plus would be the placement of the power switch.  In order to prevent that awful popping noise that occurs when you power up a speaker set remotely (such as by flipping the switch on a power strip), you'll want to use the unit's built-in power switch.  Unfortunately, this is located on the back lower part of the amplifier/subwoofer, under the wiring connections and generally in a place where you will have trouble reaching.  Usually, the sub gets tucked away under a desk or in a corner, and thus the switch location is rather terrible.  Logitech systems, for example, often have a remote or hardwired control pod which includes power and volume controls.Build quality on the speakers is also a plus.  The subwoofer is sturdy and rugged MDF, with a quality black coating and a firmly attached rear amplifier panel.  The satellites are injection molded plastic, but it is thick and strong, and the bases (which can be removed for optional wall mounting) are coated metal.  I have had the speakers for several years now and they have never once acted up on me or required repair.All in all, the Klipsch Promedia 2.1 set is a phenomenal, spectacular set of speakers for a relatively cheap, 2.1 style unit that was designed with computer audio in mind.  With a few adapters, you can easily use this with your TV, XBox, and many other devices, as I currently do.  Again, larger home audio units will provide better and louder sound, but these will also cost a great deal more.  I would highly recommend these speakers to anyone who needs a compact setup but demands good quality sound.
