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?

"I can live with 40Hz"

I agree Twl. If the speaker handles 40Hz really well it's much betteer than having something that stumbles over something lower. I've been building two ways for a couple years that max out at 39Hz, but handle that well, and for lots of music I never miss a thing.

I am moving in your (FR) direction though.
Continue to let us know what your doing and how it's going.

Thanks,
This again brings us to the perennial question of whether we are listening to the sound or to the music. It is pretty clear when twl makes statements like "I can live with 40Hz" that he is opting for listening to the sound.

THERE IS NOTHING WRONG WITH MAKING THIS CHOICE. Please...hear that.

In my judgment (not revealed truth, just my judgment) this is why people choose tubes over SS and vinyl over digital: They want to listen to the sound.

That's a good choice...a legitimate choice...in every way a valid choice.

But that is not the same as listening to the music.

Off to NYC for a week of concerts and shows. Y'all have fun! Great 4th of July to all!

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.
Bishopwill, if the "sound" never reaches my ears, I cannot hear the music. Music is a sonic phenomenon, in presentation, at least. I am not going to take your bait for the analog/tubes vs digital/SS debate. I have stated my points on those issues on other threads. If my speaker design choices, source component choices, and amplifier design choices are not your "cup of tea", then by all means, make your own selections. I use over 30 years of listening,studying, designing, building, buying, and employment in high-end audio shops, as well as being a musician, concert goer, music and record collector and enthusiast, as my basis for my choices. I have listened to virtually every type of music and every type of equipment made for its reproduction. I have a strong background in music, its theory, practice, and performance, and a strong technical background as well. I feel well equipped to make good decisions for my listening needs. I fail to understand why you, and a few others, need to follow my posts around the forum, making sugar-coated insinuations about your perceived lack of ability on my part to understand music, its reproduction, and technical merits of various designs.If you have additional problems with me, please take it off the forum and email me personally.
TWL: Had I suspected this of you earlier on last week, I would have picked up and shipped, gratis, a few dozen sound effects LP's that I stumbled across @ a local thrift (many still sealed), just to get on your good side (may need some help/ good advise on my single driver project down the line:-), though sub 40 Hz is really required to properly hear all of the "kids in the pool" on the "toilet flushing" track. LOL. You still here Kelly, (how's that for a run-on sentence)?
