Subwoofer issues.

Trying to tune a 6" PVC pipe to 46hz.

Anyone know if I could work of a 1/2 wave so I can load the rear with 1.87 meters (in lieu of 3.74m)?

If I load the front with a 1/3 of that, can the tube be run efficiently out of phase?

(5.5" woofer with a serious x-max being mounted in a 3 to 1 length configuration.)

 

harryotto,

Are you trying something new for experimentation purposes only? Or are you trying to apply a particular ported enclosure design?

I have always found the http://www.diysubwoofers.org/ website by Brian Steele a great resource over the years.

Ciao, Tim

 

A little 5.5" speaker tuned with PVC pipes makes a bongo drum speaker. Boom, boom.
Bass sounds in music are more than just a single frequency.
The 5.5" speaker is too small to be a sub-woofer and is too small to be a woofer.
If it is mounted in an enclosure designed for its spec's then it will go down to about 90Hz.

A woofer is 8" or larger so it can produce frequencies down to about 50Hz.
A sub-woofer is 10" or larger so it can produce frequencies down to 20Hz.
