Post Subject: Mechanical differences Altec 288 versus Vitavox S2 what makes them tickPosted by morespeakers2 on: 2/1/2013

So in an effort to learn something about the way the 288 and S2 sound the way they do, what do you suppose the mechanical differences in the construction of each driver that causes the differences in sound as they look so similar physically? 

I realize you may not have a 288 on hand but maybe you had both drivers together on the bench at  some time in the past.

I ask because I have been bitten by a bug to machine my own phase plug out of some sort of wood to get rid of the plastic tangerine plug.

Do think it may be possible to "wake up" the Altec sound with some slight changes to the phase plug details?

My thoughts are to the diaphragm to phase plug gap and possibly making this adjustable as wellas trying the different plug designs, salt shaker with tiny round holes, annular circles, tangerine (slits) or a combination each.

I think some laser interferometry might be helpful with this to see where the diaphragm is making its noises at the different frequencies but what do I know. I would be lying if I did not say the only thing I know about laser interferometry is what I saw on a TAD brochure from years ago. The laser machines seem to cost $25,000+. Maybe there is a lab that will analyze your driver somewhere?

I am just a hobbyist but as you well know the sound industry does not seem to have a handle on things when it comes  down to the finest details that really matter in producing good sound and unfortunately barbarians such as my self are forced to try and shape   our rocks and sticks together to fix half done work. They sure seem to have a handle on trying stupid synthetic materials that always suck in the end though.

Thoughts??


No Vitavox info below........ I am the original morespeakers  (email account gone from "morespeakers" so hence morespeakers2 moniker).
So my next post is about seven years later maybe even slower than glacial movement these days.....That does not mean I have not been looking and learning in the mean time.

Have to say that just about every time  I do a search for even the most esoteric of playback reproduction I always seem to see at least few links to the Good Sound Club in the search results for many years now. 
Please keep up the good work!
