Default DIY Super Cube full range speakers

Since my room is so small I need small speakers,the OB's i made with the same 4" driver were nice but I wanted more bass so I built these babies! These cubes are strong down to 50hz with useable bass at 40hz according to my frequency test LP.To get bass reinforcement anywhere I place them I decided to place the port on the bottom of the cab.My stands have rubber isopads to allow the port to breath.The port is loaded with a 3" long pvc pipe.[IMG]Click the image to open in full size.[/IMG]

They look good. What drivers are you using? Is that your own cabinet design?

Thanks for the complement.The drivers are unknown... I retrieved them from an old pair of speakers my father gave me.They have treated foam surrounds and a whizzer cone.On the back of the magnet it reads "9300/9900 4ohm".Yes, the enclosure is my own design.

The cabinets are 8" square and have a 1-3/4" diameter port on the bottom center of the box which is loaded with a 3" long pvc pipe running up the center of the cabinet.I use a nice amount of fiberglass insulation on all sides and around the port tube just so the opening of the mouth is visible. I used Boiled Linseed oil for a classic hand rubbed oil finish.

Looks very nice.

For future projects you may want to bear in mind a cube is a not ideal for standing waves, and neither is a square baffle with the driver centred for for baffle diffraction.

You also need a lot more breathing room for the port ideally.

Not trying to put a damper on things, they do look nice - but you could get even better results
