Introduction: Turn Your Bass Reflex Speakers to Passive Reflex

By

passive reflex speakers are higher quality and have much faster responce exept they are hard to find and expensive so why not change all of your bass reflex speakers to dipole passive for extremely cheap.

-Note this will not improve all speakers (mine were very cheap and as pointed out by Arx the enclosure was not tuned to the maximum and adding the diaphragm improved the tuning)

-I also would like you to know that the sound produced by adding this will be different.  I recommend that you compare your two options to see what sound you prefer. 

Step 1: Materials and Supplies

-tape
-speaker
-scissors
-latex (balloon, glove, ext.)

Step 2: How to Do It

Cut a flat strip of latex big enough to cover your bass reflex air port.

Tape it tightly over the hole and be sure there are no leaks

Fire it up with these tests:http://www.stealthsettings.com/woofer-bass-subwoofer-sound-test
       Number 10 is best

My mod took about 5 tries for best quality, you want the smallest square possible and as little latex contacting the tape as possible, tell me if it improves your speakers.

Step 3: Alternate Ways

 if you want even better quality hot glue an old speaker of the right size into the hole or use a piece of poster board with a latex ring around it.
