Hello & Good morning !!

[dionisio]

Hi everyone,
I found my way here through Pass DIY ( big nelson fan!). This website is truly amazing!
I've been into electricity & music most of my life. Audio electronics is something I would like to try to understand better. I have a humble understanding of individual components but lack the vision to see how they cooperate as a circuit. I belive i've come to the right place.
Anyway I'm looking forward to chatting with you guys about all this fun stuff and hopefully someday I will come up with a really cool idea that I can give back to the community.

Well for starters (please feel free to laugh, I do) I built a voight pipe (yes, one) about 4 years ago. It sounds very nice indeed. I started the second one and my tube amp gave up the ghost.(PS caps, I think) The amp is a 44 yr old stromberg & carlson 6l6 pp design. I have been quite badly digitaly maimed on other forums for revealing this as, PP amps are reputed as well rather... taboo.
Actually I thought it sounded quite musical coupled to the voight
Any how, off to a great start, I shall revive the amp and finish my other speaker And then....Klein horns!! mmm tasty!!

Gotta go for now
Thanks for reading

Welcome to the forum... it is a monster, there are corners i've not even been too

Nothing wrong with PP amps, just harder to get really good vrs an SE amp, but when you do....

What driver in the Voigt?

Hi dave
I've tried a few different inexpensive full range drivers in the pipe and came to settle on the RS 1354 , the best by far. I would like to try some more as time and money allow ( fostex maybe lowther someday) The 1354 is a nice driver for the money although a little loose in the bottom. The midrange is very good.

Have you done any of the "standard" tweaks. If not there is a lot more you can get out of the humble 1354. Is it a classic voigt? If yes you may be able to tighten up the bass by restriction the port somewhat. The refernce design for these is Bob's ML-Voigt. When i get around to my 1354s i'm going to do a bipole variation on those....

I'm not allowed to make the pretty cabinets -- Chris or Scott do that (we are into team DIY )

Hi dave thank you for the links !! I especially like the bipolar design.
I've tried a few tweaks, I really don't know what the standard tweaks are.
I don't remember who's voight design I used, I changed the design, kinda rule of thumb to make it easier to build with what I had on hand for materials and tools. The only real difference is that I put the port on the bottom and made the legs adjustable to vary the port height off the floor

Ductseal the basket (and use it to shape the area between basket & magnet to make it smooth)

treat the cone... dammar seems to be standrad, i like puzzlecoat on the cone and dammar on the whizzer

the 98 cent tweak (various ways of supporting the whizzer at its edge). I use a thin piece of light foam rubber cut into a strip and wrapped around the outside of the whizzer so that it damps tha whizzer's outer edge.

Then -- not a regular tweak -- but a significant one is a dustcapectomy & addition of phase plugs.

PP most certainly isn't taboo round here!

Thanks again Dave for pointing me in the right direction!
I can't wait to start working on it. How do you like the phase plugs?




Thanks for the warm welcome Jason
