June
26th 2004 Woofer module begins
The woofer module will be made of a constrained layer of 18mm particleboard
instead of MDF (for weight reduction), barium-loaded PVC and 6mm MDF. The
front baffle will be an identical construction to the satellite - i.e. 27mm
MDF. My target weight is about 40kg, which is about as much as one person
can safely lift. |

together the front baffle (12mm / 3mm / 12mm MDF) with PVA glue and then
attached the curved edging. |

This creates a total sidewall width of 27mm and absorbs vibrations extremely
well. |

24th 2004 The narrow woofer baffle
As the 10" woofer overlaps the curved edges, small fillets were required
to fill in the gap.
These were a pain in the a%& to make. |

Jan
7th 2005 Veneering completed
After a mid-project break,
it's finally time to dive back in. Lots of sanding and painstaking preparation
before applying the iron-on veneer. Iron, let cool, and repeat untilI'm
sure of a strong, bubble-free bond. This stage took about 6 weeks on and
off. |
