Hello, steemians, and welcome to my page, eh!
I had planned on working on a couple of my music projects yesterday, but I got distracted by a different project instead. That tends to happen fairly often for me. I ended up working on a speaker box project instead. I had gotten most of the parts I needed to finish the project recently, and that just kind of took over my day.
This speaker box had been given to me last summer, it was a double subwoofer box for a car or van, the box was empty and in need of a bit of work when I got it. The box had gotten wet from sitting outside and getting rained on, and that's not good for the chipboard that these things are made of. I brought it in the house and just let it dry out for about a month, and then I painted the interior of the box with spray cans to seal the wood on the inside.
The box is a 2 subwoofer box with isolated speakers, the box is sealed between the speakers. Both speaker chambers are ported, the only parts that were still in the box when I got it were the port tubes. The box was made for 10 inch woofers, so I figured that I could use it with a pair of 10 inch musical instrument speakers for playing the bass guitar through. I had the extra speakers that I had bought a number of years ago for a speaker project that never got done, so this seemed like a good way to use the speakers.
I had to come up with a pair of speaker jack mounts for the back of the box, and it took me a while to find mounts that would fit in the holes in the back of the box. I finally got those, and the hardware necessary to put the speaker jacks into the box, and yesterday ended up being the day to work on the box.
This is what the box looks like.
You can see how I painted the inside of the box with the spray cans. You can also see the back side of the speaker jacks here. You can also see the interior wall that separates the 2 speaker chambers to isolate the speakers from back pressure from the other speaker.
This was my temporary work bench. I was using the old wire stripper/crimper for a clamp to hold the jack while I soldered it. These are the good Switchcraft 1/4 inch jacks, but I have found that the ground can get loose if you don't solder it to the mounting tube, normally they're pressed together.
After I had the jacks soldered, I remounted them in the mounting cups, and started the process of wiring them. I had drilled a hole in the center wall of the cabinet so that I could wire the speakers together in parallel. You can see the second wire going toward the other side of the box.
I mounted the first speaker in the box and then started on the second speaker.
I mounted the other speaker in the box.
One of the speakers has a dented voice coil dust cover. That doesn't affect the performance of the speaker mechanically, but it affects the high frequency response a bit, not that these speakers have a lot of high frequency response. These speakers are musical instrument speakers, and are designed to put out a lot of bass response.
After I got to this point, I discovered that I don't have a pair of grill covers to protect the speakers, I have to order those to finish this project. I eventually want to put a switch in the box so that I can electrically isolate the speakers to use the cabinet with a stereo output bass amp. As it is now, I can plug an amp into either jack and power both speakers. These are 8 ohm speakers, so the total load to the amp will be 4 ohms, the proper load for a Fender tube bass amp head such as the Bassman 50 or Bassman 100. The speakers are rated at 150 watts RMS each, so they will handle any amp that I have right now. I'm looking forward to trying this speaker cabinet out with one of my 50 watt amps. It should have more punch than my single 15 inch speaker cabinet.
Well, that's all I have for this post, I hope you found it interesting!
