Voxel - a mini-sub+

Re: Voxel - a mini-sub+

If you can find another sub the size of a shoebox that can play below 35 Hz, build it!

Cant say exactly how low, but IIRC, I built a 6.5" buyout sub in .56 cubes ported that played down to the upper 20s with decent power handling. Not by any means the quality of the TB, but great for music and movies in the bedroom.

Re: Voxel - a mini-sub+

With W6-1139si and Dayton SA70 plate amp:
What adjuatments are needed to have these two in a Voxel Sub?
Is it possible?

Yeah - I love my little Voxel, but often I want just a bit more boom
The TB 6.5 TB-w6-1139sif-sub--264-919 is such a great value.

Well, to be fair, you did use a 25 watt plate amp with it. That W5-1138 can handle much more.

Re: Voxel - a mini-sub+

I'm probably going to build a Voxel in the near future. Based on modeling in Unibox, I'm thinking the 70-watt Dayton is a good choice.

Thanks for posting the design Paul! I recently built a Sprite & I'm enjoying it.

Thermal power handling is only 40WRMS for the 1138, and 70W is more than it can handle.
In my modeling 50W is pretty much the hard line.

I agree on the 50 watts. Good judgement on how much to turn up the volume is usually necessary in these pursuits.

Re: Voxel - a mini-sub+

I'm building a pair of these. What methods have prior builders used to connect the port tubes together? Merely gluing end to end with Crazy Glue seems inadequate. If I can find a plastic tube with an ID similar to the OD of the port tubes, I'd feel more comfortable. Any suggestions?

Re: Voxel - a mini-sub+

I've used two methods: Hot-glue (tacked in 4 spots to hold them together) and then went all around kind-of smearing glue across the seam. Alternately, have had just as good of luck with a nice 2" wide tape without issue (I used duct tape, which may get some other people to suggest better options).
There is no pressure on the port, other than when you move it around or bump it, so it doesn't require a huge amount of holding force, just enough to support the weigh of the port so it doesn't come apart.

Re: Voxel - a mini-sub+

I used e6000 and also wrapped blue tape to hold it together. Seems to work pretty good.

Nah, Duct tape is your friend. I've done the same.

Re: Voxel - a mini-sub+

Household Goop is magic stuff. Once that stuff takes hold, it's pretty much never coming off. I would use that in conjunction to some sort of tape to hold while the glue dries.

I used that method as well.

Thanks all for the tips.
