Baffle Board Creation

Here are some photos from the cabinet creation process.






This was the first baffle board I made for the speaker. I wanted to incorporate a threaded mic clip mount directly on the baffle so a mic could easily be placed for performances or recording.


On my first baffle, I placed the speaker hole just a little bit too high, causing the magnet on the rear of the speaker to interfere with the working on the back of the amp. In the above photo, I have just clamped it in place to test.





Here is a sequence showing the 2nd baffle being covered by burlap. Since I chose to leave the amp unfinished/uncovered (other than some clear polyurethane), I wanted to use something simple and natural for the grill cloth. After a local search failed to produced some old coffee or feed sacks, I purchased some plain brown burlap.



I began by cutting two pieces of burlap and stapling along just one edge. Burlap is very sound-permeable, so two thicknesses should be more durable.







After one side was completely secured, I attached the other side to a scrap strip of wood, leaving plenty of extra. This allowed me to pull all the slack out uniformly from the original side I stapled.


Once all the slack was pulled out, I stapled across the other side, keeping it all taut. Then I cut off the extra and secured both remaining sides.


Bolting in the speaker.


To keep the front grill free of screw holes, bolts, etc., I attached the baffle to the amp cabinet from the rear. I just ran some wood screws in from the rear and that pulled the baffle right up against the baffle support strips.

The finished product came out as good as I could have hoped. As usual, there were a few trials-and-errors along the way, but it looks and performs great.
