New Lowther Drivers.

I have ordered a pair of the new, improved Lowther DX3. The improvements consist of changing the suspension from a rolled-out type to a rolled-in type, putting a rolled edge on the whizzer cone to stiffen the edge and eliminate the midrange peak called "Lowther shout". They also offer a new phase plug that looks like a "light bulb with holes" that is controversial. Bullet style phase plug is still standard. They are sending me both types for evaluation.
I am currently building a set of Voigt Pipes enclosures, which I hope to get done before the drivers arrive. I am following the plans from the Lowther Club of Norway website.
I'm very excited about this, because I could use some extra efficiency in my speakers. If anyone has built these Lowther Voigt Pipes before and can offer some advice, it would be appreciated. It is not really hard, but sometimes a simple tip can make the difference. BTW, Doug(Grandpad), you really helped me to make up my mind on buying these drivers in the last thread I put up on this topic. As always, I will give reports on results, just in case anyone is interested. Comments?

Here's another variation of the Voigt Pipe that you may be interested in: http://indigo.ie/~walton/voigt.html Also, there is a construction tip on the Pipes at that site.

The "Pipe" is a bit larger than the original and has a modification at the bottom of the cabinet, which according to the builder, helps smooth out the bass response.

There is another cabinet that looks to have a lot of potential and is a variation of the Voigt Pipe. I saw it on the Single Drive website under the DIY menu, titled: Bigger is Better. Basically, it looks like the Voigt Pipe but has the "other half" of the Pipe attached, and the port/mouth opens up toward the ceiling. The fellow that built these speakers has some tips in building them that may be useful to you when you build your Voigts.

Please keep us udated on your Lowther DX-3 Voigt speakers.
