The MidiLand S4-3050M Speakers
   
    
  Introduction
  Want 
    to know the secret of some great products? Not a new concept, but if a manufacturer 
    collects various pieces from other great products and does a mix & match, 
    quite the interesting creation can take shape. Remember the S4-4060's? Grab 
    the satellite modules. Think back to the MLi-490's. Pair the excellent 6.5" 
    polypropylene subwoofer with the aforementioned sats and violá! A seemingly 
    new speaker system emerges.
  When 
    I was informed of the opportunity to review the 3050M's, I jumped. Why? Because 
    the satellite modules and the subwoofer impressed me in earlier reviews and 
    months ago, I briefly thought, "geez, this piece with that piece would 
    make quite the audio marriage." Thanks to MidiLand for the review samples. 
    Let's see how successful they were at integrating two pieces of previously 
    successful systems together.

  Description 
    & Specifications
  While the 
    subwoofer enclosure isn't a mirror image of the 4060's, it is very similar 
    to the 490's reviewed many months ago. You may recall that the 6.5" polypropylene 
    unit garnered more than faint praise from this dedicated listener.
  Similarly, 
    the satellites dug up memories of satisfying high frequencies from a single 
    full range driver. No, the 3050M's don't possess a tweeter, but if there were 
    any such full range driver that sounded like one existed beneath the acoustic 
    covering, this 2.5" would have my vote.
  All controls 
    are mounted on the subwoofer housing itself. This made me bend over and reach 
    under my table far too many times to adjust the volume, so leaving your system's 
    desktop audio controls active and minimized becomes almost mandatory.
  Gray isn't 
    exactly my favorite color but what struck me as odd was the off-white coloring 
    of all the connector wires. Somehow, it seemed out of place on a system attempting 
    to make some kind of non-off-white fashion statement.
  The satellites 
    also sport the 15º and 25º tilt option. When aligned one way, they 
    point at an angle that is either 15 or 25 degrees above the horizontal normal 
    of the table surface. In general, this might prove sufficient for those users 
    that prefer the lazy man's slouch position, whereas the nose barely peers 
    over the keyboard, but as for some of us that value our spinal columns, I 
    preferred to raise them 4 inches above the table. 
  A quick look 
    inside revealed a smallish 6,800µF 25V main filter capacitor and seemingly 
    MidiLand's favorite Philips OM8383S four channel amplifier. One of these days, 
    I'm going to find someone at Philips that will "leak" that datasheet 
    in my direction. For now, all I can do is speculate on how it does its job 
    so well.
