Today I collected some data. I've got an Adire Tempest driver built into an "Adire Alignment" box. It's an awesome sub. To collect some data about it I used a CD I had created with sin waves at HZ levels from 20 up to 160 in 5 HZ increments. I set the amp gain all the way up (AVA250 rated at 270W), the crossover to the middle (maybe 100 HZ?), and the volume at about "26" on my Kenwood 1080VR receiver (0 being the loudest, 99 quietest). I then collected DB readings with my radio shack meter from my standard sitting position. (I mounted the meter on a chair so it wouldn't move). Well my results were interesting. http://www.telusplanet.net/public/kord/tempest Hah. Pretty crappy eh? My guess is that all the junk in this room is absorbing sounds and messing with reflections. For some frequencies, simply moving my head up/down/left/right would make the bass dissapear, or become incredibly strong. It's particularily annoying. Unfortunatly, I can't do anything about this. I'm but one of several people living in this home, and my dad is mad enough about the sub as it is - no way I'll be able to renovate the basement to get a better home theater. Hah. Oh, and by the way. Did I collect data properly? Is there a different method I should use? Jonny K.
