I needed to add some low end to my 20 inch kick drum so I decided to give the KickPort a try. For those of you not familiar with the KickPort, it’s a small plastic tube that gets inserted into the kick drum’s resonant head. Attached to the tube is a rubber flap that is used to seal the KickPort once it’s inserted. It’s claim to fame is that it boosts the kick drum in the same manner as a bass reflex speaker cabinet boosts low frequencies.
I decided to go to Guitar Center to pick one up. It comes with a 5 and 1/4 reinforcement ring; however, I was told that it works better if you cut a 5″ diameter hole instead.
My resonant head had no port, so I decided to make the 5″ hole for the kickport. I have to admit, it made the process a little challenging since the kickport itself is almost 5″ in diameter. I had to remove the resonant head from the drum and place heavy duty rubber bands around the cumbersome rubber flap of the KickPort in order to nudge it into place.
The 5″ hole creates a really tight fit for the Kickport, which gives it solid stability.
Using my iPhone, I did a lofi recording with and without the Kickport using the same resonant head.
Here is the audio using a REMO Emperor coated resonant head with a 5 and 1/4″ hole without the KickPort :
And here is the audio using REMO Emperor resonant head with a 5″ hole and KickPort:
You can hear the KickPort takes away some boom and adds punch and low end.
The only downside is that I don’t hear as much tone as before. KickPort’s documentation states that it increases tone, while other websites are stating that different resonant heads yield different results.
