PLOrk_speaker_building_to_do_list (A list of problems and stuff that needs fixing)

A place for useful notes on building the new silver hemispheres, sorted by step:

The Exoskeleton

  • Make sure feet are in the right place BEFORE drilling holes for the amps. :-(
  • Screw holes:
    • Amps: 5/32"
    • Power jack: 7/16"
    • Pot.: 3/8"
  • Don't break drill bits.

The Guts

  • Audio wires from the RCA sextet to the 6-channel pot need to be a little longer than we first thought: 14"-16" inches
  • The white wire with the blue stripe (attached to the amps) is junk - replace all of that
  • Striped wire = +12v
  • Scott's new color-coding for the RCA sextet: 1 = Blue, 2 = Blue/Black, 3 = Orange, 4 = Orange/Black, 5 = Green, 6 = Green/Black
  • Channel numbering for the RCA jacks on the bottom of the speaker:
    • White row: 5 4 2
    • Red row: 6 3 1 (5 and 6 seem backwards - we should check again)

Preparing the rings and drivers

  • The sticky stuff on the foam rings for the drivers isn't too good - a lot of them fell off over night. Maybe save this step until the drivers are ready to be screwed on to a hemi.

Installing The Drivers

  • Don't forget to put the ring over the wire before soldering the speaker to it. Forgetting to do this is lame. Current score: Dan: 5 or more, Jascha: 2, Cameron: 1. dan wins!!! (Putting the ring on backwards is also lame. Current score: Dan: 1, Jascha: 1.)
  • Trim the excess tape from the screw-holes with something before putting the screws in - not doing this can sometimes gum the screws up and make it annoying and needlessly difficult to get them in.

Checks, Configuration, De-Buzzing, etc. (added by PRC 4/20/08)

Stuff I'm checking on all 8 DeLoreans:

I. Channel Order: Channel 1 is Presonus front, speaker should face you with volume knob on the upper right.

That's channel 1, channels 2-5 process clockwise (looking from top), and channel 6 is top speaker.

II. Filed/Dremeled a couple of rings where the volume knob rubs.

III. Put feet on the PreSonus

Unit 0: I, II, III

Unit 1: I, II, III

Unit 2: I, II, (No Feet on this one, something funny, but don't worry)

Unit 3: I, II, III

Unit 4: Dan's Got This One right now

Unit 5: I, II, III

Unit 6: I, II (Need to find more feet, please find Presonus Manuals, feet therein)

Unit 7: I, II, Need feet


  • debuzzing: there is a wire cover on the wire between + and the cap on each driver; it is loose and rattles at some freqs. it's best to tape it down with a little electrical tape; seems to help a lot. (dt)
