| I started construction on these speaker cabinets waaaaay back when
I was 17, so naturally they had to be BIG. They survived very well in storage
for years, until I finally decided to finish them. Construction is 3/4"
hard particle board, with screwed and glued joints. An internal bracing
network of 2x2" maple stiffens the panels to raise their fundamental frequency
above 4K, reducing the cabinets tendency to vibrate at lower bass frequencies.
The enclosures are covered with Walnut veneer, and have 1/8" hardboard
sheathing on the back and bottom.
These are air suspension type enclosures, with an internal volume of about 5 cf. This was calculated for the woofer originally used in the design, and is close to correct for the current speaker complement. The enclosures are lined with fiberglass batting. The speaker grille frames fit snuggly into the recess formed by the inset of the speaker board, and do not require any attachment schemes. They are covered with a stretchy spandex-type cloth; black with silver highlights. These speakers are by no means perfectly optimized for peak performance, but they have excellent bone shaking bass response and full, lifelike mid range and highs.
