Converted a "Bass Reflex" sub into an "Infinite Baffle"!
G'day folks,
Here's something that I finished today I'm very happy about.
This is a Brand New sub that I purchased a couple of months ago. The cab is made by "Audio Enhancers" and is a driver specific enclosure; not a generic speaker box that could be bought at any Pepboys auto parts store.
It was designed to be used with "JL Audio's" 10W6v2-D4 drivers. But being a "Ported" design, I was having some problems with a loud, but Boomy sounding (uncontrolled resonance) bass, which was unflattering to the ear, and some what, unintelligible in the lowest register.
I decided that a "Sealed" enclosure would be a better choice for this suv. This will eliminate the boominess, and the resonant peaks that are characteristic of "Bass Reflex" cabinet design.
I went to Home Depot last Sunday and picked up two, 11-1/2 X 1-1/2 X 3/4" pieces of plywood to use as inserts to block off the two "Duct ports", seen on either side of the cab.
I used a can of light gray spray paint (no dark gray available) just to help camouflage the block-offs. Then I drove them into the mouth of both ports. I put a bead of clear silicone sealer (caulking) around the seams, to prevent any air leaks.
Next I removed both drivers from their baffles and "stuffed" both rear (partitioned) chambers with "Polyester fiber" batting material to absorb any standing waves, and to slow down the resonant back wave, making the drivers behave as if they were in a much larger enclosure for the "Lowest" bass possible.
I tested the sub and...Unbelievable!!! I knew that it would be better, I just didn't think that it would be "THAT MUCH BETTER...WOW!!!"
rigtec, cheers!
