Cooper Time Cube DIY / Time Bucket build

If the pipe is too wide, mids and highs get crossways in it, get garbled and cancelled.

Also I believe they will want their tube back in a day or so.

I found more stale crumbs. Speaking tubes at 100s of feet were 2" or 3" diameter. This is perhaps too wide for High Fidelity, but speech (and much guitar) can pass a much smaller band.

thanks Paul,so based on that about 1.5" should be optimum for a 100' TimeCube delay.

I had another thought a few days ago,I am also going to try a small DC fan with a rehostat  to control the speed,placed in front of the main driver/transducer.This should add a nice "vibe/phasey"  sound to the delay.It can be turned off or sped up or down rather easily too.

IDK how many times I said "Luke I am your Father" "Come to the dark side"  into our standing room fan as a kid...

@Wavely  Is that a real cave/rock type cistern or cinder block?
That's really cool!
When first researching the Time Cube after PRR mentioned it I ran across a thread dedicated to building "reverb rooms" in your attic.
I would have started already if I had the money ,my attic has a good 7' - 8' peak and there is enough room to make a 4'- 6' x 6' x 30' closet in the attic,perfect for a reverb chamber and could double as extra storage space too,but money,money,money,grrrr!

I keep thinking about this, so I may as well ask ....

if you put a microphone behind the speaker, it will be out of phase respect a mic in front, no? maybe the mic elements facing back to back, I don't know. but, if you now have reversed phase, what if you ran another, shorter tube from behind the speaker, with your new, anti-phase signal, and then mixed/added/whatevered the resulting delays? something? maybe tremolo the anti signal in.

That's an incredibly long time for a "room". Even a basketball arena doesn't have a 100mS delay gap.

Also: you have amplifiers. You can accept more loss than a voice-powered tube.

When you try to get 100' of 1.5" pipe in your Civic, you will be thinking smaller.

Cinder block (actual cinder block, not concrete), the roof of it/floor of the porch is concrete.  I really love it, it has a very unique vibe to it, also depending on what amp, speaker, and microphone combo I use it takes on different identities.  My neighbors told me that there is a second cistern near my house but can't remember where it is, only that it's underground.  I have a feeling that it might actually be a small cavern type thing, but I haven't gone digging to find it yet.
