Step 1: First Step Find Yourself a Log
Try and get one that is roughly the same diameter over at least two foot of length it's easier if there are no branches on the bit you want to use unless u want the branches sticking out as a stand of some sort?
Sorry I'm writing this after making so photos are not great of the steps involved. next time I will take before photos as well ( planning an 8" sub box from a log too just need to find a log now!
Step 2: Hollow Out the Log Blank
U could use a hole saw or core saw or flat bit probably a lot easier than the method I used but that will only really work for smaller speakers.
After drilling the holes I broke out the centres with a hammer and chisel roughly to full depth but was left with a rough bottom on the hole ( wood was still wet )
Step 3: Finishing the Hollowing
I draw a circle around the hole to just under the size of the speakers so I could slowly carve the hole to The exact size of the speaker so it was a tight fit which will get tighter as it drys (hopefully it doesn't split just have to fill the crack if it does?)
Step 4: Wiring
Step 5: Enjoy Separate Front Surrounds
I have not fitted terminals on the back and just have the wires going to a junction box as I did have them wired in series but have now just wired them in parallel as they sound more balanced with the rest of the system!
Hope to see. More like this and like I said earlier I am going to do a sub box for an 8" and will take more photos of the steps to write a better instruct able.
