It's... it's...

Thanks, Nelson for a terrific Christmas present
and may God rest ye merry.

That's stunning looking... Probably the neatest use of
sonotubes since sonotube telescope tubes.

Thank you for another fun project.

Merry Christmas!

That's it! It reminded me of a Dobsonian reflector
telescope (the pre-party version with the box, that is.)

Always did want to build a 12" reflector... maybe
now it will be a 12" El Pipe-o.

Best,
Erik

Thanks! and Merry Xmas to all.

N. P: That's just super! Thank you, and Merry Christmas.

Nelson, that was a very funny article. Sounds like the name alone brought back the good times in a grand scale. Must have been alot of fun to use an $20,000 amps to blow up $400 woofers. I wonder what it must have been like just before that happened.

Thank You and Happy Holidays!

I only see Dells

An externally hosted image should be here but it was not working when we last tested it.

Did you try just typing it in? That seemed to work for me.

In the student center at the 'Tute, there used to be this ice cream store that had damn good icecream, and this big sonotube sub. Naturally, it was a Bose sonotube. What was interesting is that both "phases" of the woofer were loaded with transmission lines of different length. It's basically the transmission line equivalent to the acoustimass bass reflex alignment. Has anyone tried something like this?

Hi
Only see dells :

I fixed the problem.

 

[Duck-Twacy]

Much better

D*mn, that woofer (21") is discontinued

 

[Digi]

I need a sub for my new project, El-Pipe-O may fit the bill. I wonder what Nelson's sub would look like if he built it like one of his own smoking appliances? J/K Time to track down some sonotubes and give it a whirl. Cool execution of a trannie line Nelson, thanks!!!

If the original drivers Nelson used are no longer available, you could try for the Hartley 24" of legend. Last I heard, they were still available.
I believe Magnat also has a driver in that class.
If all else fails, you could try to score one of the old JBL or EV 30" drivers, though you'd have to locate somewhat larger tubing...

Stunning project Nelson, thanks for this remarkable Christmas present.

My girlfriend agrees with Nelson. Size does matter!

Merry Xmas to everyone.

You know, I believe I must have subconciously remembered
the Dobsonians. Such elegant telescopes.

What's the difference between SC and NP?

Santa Claus make gifts only for Christmas and Nelson Pass make this all the time!

 

[jh6you]

When I first saw El Pipe-O, I thought it as a gift box dropped into the fire place through the chimney.



Merry Christmas!

 

[Duck-Twacy]

Horizontal?

I have a 8 foot ceiling.
What happens when you lay the tubes on the floor (against the walls)?

Maybe a bit offtopic here under amps

 

[GRollins]

Horizontal transmission lines work just fine. Better in fact, with the port being at the floor, you'll get a nice boundary to help things along. If they're at the junction between floor and wall, so much the better.
For that matter, the same principle works for reflex cabinets. It's not the laying down that makes the difference, it's the final position of the port.
