Vifa Floorstanding 2-Way Project
Here is a rendered image of the speakers I am currently building.
The drivers I will be using are the Vifa P17WJ-00-08 6.5" poly cone woofer
and the Vifa D25AG-35-06 1" aluminum dome tweeter.
The enclosure walls are 1.5" thick MDF (Medium Density Fiberboard).
For damping, I will be using 1.5" eggcrate acoustic foam on the internal divider and back wall.
To avoid long standing waves, there will be a divider piece of 1.5" thick MDF
near the bottom of the enclosure angled at about 30 degrees.
Outer dimensions of the enclosure are 48" H x 8.5" W x 11" D.
The internal air volume is about 1 cu. ft.
There will be a port in the rear of the enclosure with an internal diameter of 2.5"
and a length of 6.5" to tune the enclosure to 40Hz.
For a crossover, I will be using a series crossover design crossed around 4000Hz.
This will allow the 6.5" driver to use it's full bandwidth.
Here is a diagram of the crossover I will be using.
I will post more detailed drawings and a how-to later when I get my design more finalized.
Here are all the electronic parts I will be using.
Here are the doubled up (two layers of .75" MDF) pieces of MDF for one enclosure.
As you can see in the image, I used LOTS of screws to hold the layers of
MDF together for the glue since I didn't have enough clamps.

One speaker constructed. Just needs some touch-up work.

The speakers are all done! They sound very well so far, though
I haven't had a chance yet to really test them out. Highs are crystal
clear, mids are very smooth, and the bass is clear and present until
around 40-45Hz where it drops off. Although not perfect, the semi-gloss
paint looks pretty good as well.
