My eagerly awaited copy of Home Theater Magazine arrived today which contained the second part of a fairly lengthy two part subwoofer test. The subwoofers on test were :- Adire Sadhara Canton AS50SC Earthquake Supernova 10 Mk 4 JBL Studio 120P11 NHT SW12 Triad InRoom Silver Totem Thunder Velodyne SPL-1000 Mk 2 The two most interesting things about the test for me were the fact that none of the subwoofers were well known in this country or widely available, even though the Velodyne brand is known to forum members, and secondly that in order to get around room acoustic problems all the testing was done outside. The summary came up with some interesting facts as his conclusion was that the bass that people hear is shaped by :- 1) The room the subwoofer is in 2) Where it is in that room 3) Where you are sitting in that room 4) What furnishings and acoustic treatments there are in the room 5) What equalization is being applied Although we know the above, the author then concludes that taken individually, each of the above factors influences bass quality to a greater perceptible degree than the difference between any of the two subwoofers in the survey. When asked which subwoofer he would buy he answered that he wouldnt buy a single one of any of them but would plump for two of the same model, probably the Totem or Triad if he had the money or the JBL or Adire if he couldnt afford the first two. He said that he would experiment relentlessly with placement and when he had it about right hed touch it up with an equalizer, leaving alone the frequency dips that are due to room cancellations and hence inherently unfixable. He would make his own bass traps and flexaural absorbers to control known acoustic problems then retest and re-equalize before coming to the best bit of all dip the lights and enjoy. I found it a lengthy but very interesting and different article to what we are used to reading.
