|Bare box inside - nice.|
|Heavy cloth grill - very nice.|
However, speaker design has changed quite a bit in the last few decades. Some notable design 'features' in these Australian masterpieces are:
- Speakers installed behind the baffle.
- Two layers of thick fabric on the speaker grill.
- Two wooden bars across the front of the woofer for protection.
- No binding posts or other terminals on the rear.
- No bracing, lining or damping material inside.
- No crossover, except for a single capacitor on the tweeter.
- Nice big cone tweeter instead of these puny little domes they have these days.
So anyway, I set about rectifying the situation.
|Starting the upgrade - polyester lining - polyester pad protecting the tweeter.|
Internal brace added between the woofer and the tweeter tying the baffle to the back .
|Rear of tweeter - note in line 'crossover'.|
|Cardboard tube bass reflex port - a DIY staple to this day.|
|More poly on the back. Caulked all inside joints and glued the|
back to the box with construction adhesive.
|Magnet-box woofer - solid.|
|Gold plated binding posts.|
|Wooden bars in front of the woofer removed. Cloth grill removed. Woofer and tweeter moved to the front. All done!|
