Towers with downfire woofer design based on the Infinity Crescendo CS3006 crossover
My goal is to achieve a clean reflex design with a tweeter and midrange on the front face and a hidden woofer on the bottom to remove visual weight and give a more modern appearance.
Tweeter: Dayton Audio TD20F-4 3/4″ Soft Dome Neodymium Tweeter 4 Ohm
Midrange: Goldwood GM-85/4 Heavy Duty 5″ Sealed Back Midrange 4 Ohm
Woofer: Goldwood GW-208/4 8″ OEM Woofer 4 Ohm
I based on the measurements of the original Infinity Crescendo CS-3006 box from which I took the crossover, changing the location of the woofer towards the bottom and leaving a free space of 5 cm between the box and the base to allow the operation of the driver.
I made the enclosure in phenolic chipboard with double wall to leave the thickness of 3 cm with acoustic foam inside, with a reflex port on the top back side. The finishes were given with Oak veneer and catalyzed semi-matt lacquer and on the front and back with black ink to achieve the contrasting stripes.
Para el proyecto utilicé algunos crossovers Infinity Crescendo CS 3006 que tenía pensando en hacer este trabajo.
The set has a very balanced sound, the bass is deep although the placement of the speakers is important not to make the bass booming, the mid-range is very rich and the voices are clear, and the small tweeter has a clear sound without distortions. that does not tire the ear. I haven’t heard an original Infinity Crescendo CS 3006 speakers, I do not expect them to sound the same or better, but I liked the result a lot and the best thing was the whole process to make them … it is very gratifying!
