DIY Super Cube full range speakers

[audiophile36]

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.

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

 

[audiophile36]

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 😉

Thank's makes perfect sense.I will try another project the proper way and post my results.

I like your experimentation!

Thanks Tade,

They do soud great even though they go against popular design.

Thanks Tade,

They do sound great even though they go against popular design.

Just the fact you carried your project off to completion says a lot for you. Good work. Its a good looking pair of speakers.

Enjoy the fruit of your labor. Learn from it, and you will do greater and greater things.

Cheers!

Thanks for the kind words. I wouldn't have imagined I could build my own speakers two weeks ago.I will learn from my mistakes and make more technically sound designs.

Nice job! How did you go about flush mounting the drivers?

Geeze… square box with standing waves and a centered driver… what’s WRONG with you?!?

Actually, I think they look GREAT and bet they sound just fine too. I remember building a speaker with three tweeters on all sides but the back (now I always put them on the back), two mids on each side and one big forward facing woofer… and I remember blowing all of the tweeters on both speakers (that’s SIX at $18 bucks each) in one loud burst of Talking Heads. At least yours play.

Peace,

PS… I’ll be in the Poconos on vacation for a week. Everyone have fun on the forum!
