Homebrew Sub-kick Project


Silver Member
I started building a homemade Sub Kick a week ago and though some might be interested in how I've been doing it. I haven't found a "start-to-finish" with pictures.

I bought an early 70s Ludwig shell for $.99. Don't worry vintage lovers, the plies were separating, black cortex was destroyed, badge destroyed...hence impetus to make something nice out of the shell.

I bought a 10" speaker and some hooks, eye bolts, and s-hooks...along with four small bungee cords.

I decided to mount it suspension style rather than hard mount it. It's in there pretty tight, but has some bounce to it.

I will wire it up and add those pictures in the next couple of days and then add the finishing touches.

OK, Finally got it wired up. I added a -20db pad to it based on some personal research.

Top left is the XLR mounted into the shell (from Switchcraft for about $4).

Note the .5w 180ohm resistor connecting pins 2 & 3.

Pin 1 is ground. I run it to the chassis of the speaker.

Negative from speaker goes to Pin 2 and Positive to Pin 3. In line with each is a .5w 680ohm resistor.

I kept the internal cables short and did my best soldering it together without making a mess.

I connected it to a preamp and then into my interface and it is sounding good just from a quick check.

I'm going to clean it up with some final pieces and post those pics in the next couple of days as well as give a sound sample from it once mounted and connected to my recording set up.

Here's a quick sound sample.

You hear a few different sounds in this order:

1st: Sennheiser e602 mounted on a Kelly Shu (raw)
2nd: sub kick (raw)
3rd: e602 (w/compression)
4th: subkick (w/compression)
5th: e602 (w/comp and eq)
6th: subkick (w/comp and eq)
7th: e602 and subkick (w/comp and eq)

I did not spend a whole lot of time getting this to sound perfect...I wanted to get something down so I can pack up and move.

Overall not too bad...I can definately feel a thump in my chest from the subkick when I play this back through my studio monitors.

A Second recording with the subkick mounted (as seen in pictures) first recording was it sitting on a cardboard box.

This is not my planned 'final' mounting method, just something that would work for the time being.

As always, feedback is appreciated. This was mostly just a fun project to see if I could do it, if I could do it for cheap, and because I had most of the pieces laying around to do it.

There are some odd artifacts on the subkick recording. No idea if that's part of your Mp3 encoding or the device itself.
