Built a speaker cabinet from an old speaker that my friend gave me. I just deiced to get into playing bass a few months ago and the practice amp that came with it was pretty bad. It’s not completely finished. I need to paint it or cover it with tolex or something. But I didn’t want to put the time and money into it until I knew I was happy with the sound. I am very happy with it, so now I get to research how to do tolex. And I have to decide on a color.

Building a cabinet for low frequency speakers is quite the endeavor. I had no idea what I’d need to learn in order to get this built. It’s a lot more than just building a box and throwing the speaker into it, though that is exactly what I did.

I bought a fairly inexpensive amp head to attach to the speaker and I am much happier now. I find myself picking up the bass more often than the guitars now.

Sorry for the lack of pictures. If you’re interested in seeing how I built it and hear a sound sample, check out the youtube video I made. https://www.youtube.com/watch?v=2lGkpTvJKPQ

I also had to make a tramel to cut out the speaker hole. I made it so it can use either a router or a jigsaw. That video will be up later this week.

Did you have to do any kind of internal baffling or stuff it with something?

Nice practice cabinet! Is it sealed or open back? I’ve built dozens of them and would suggest you use black carpet for the covering. Something like this: https://www.parts-express.com/speaker-cabinet-carpet-jet-black-yard-54-wide--260-768 works better than the tolex and is very durable. Shows less wear and tear also. That company is great to deal with and they have everything you need.

It’s a sealed cabinet, so no baffling. But I did rip open a couple old pillows and dumped the batting into the space around the speaker.

That looks pretty cool with the carpet. Totally old school. But I haven’t settled on the look I want yet. Do I go old school? Do I go with some really out there tolex like material – maybe multiple colors? Or do I go completely ghetto and just spray paint it – maybe do some stenciling?

So many choices, not sure where I’ll land.

If it is a sealed back, a port on the front would probably help the low end a great deal. About a 4” port (either from Parts Express or made from common 4” PVC pipe) 3-6” long. There are a lot of cabinet and speaker port calculators on line to help you figure just what you need with that size speaker and that size box.

Being a bass player I always suggest going with 4 10s, because it’s a much tighter sound and it’s more surface area than even 2 18s. I know your just starting and it was a speaker you had. It looks great, that’s just a suggestion for the future.

Yeah, I know all about those online calculators. In an earlier video, I attempted to measure/calculate the Thiele Small parameters since there was no documentation to be found for the speaker that I had. I came up with a HUGE Qes. All of the calculators recommended a sealed enclosure. I actually go through 2 online calculators in that video.

Due to the enormous Qes, they also recommended the enclosure to be about as big as a bedroom, so…

But I decided to build a simple, sealed enclosure just to see how things would go. If I ever get to a point where I want to play in a band, I will probably use the DI output on the amp into the PA system and just use the speaker for keeping the band in time.
