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?

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)?
Any of you guys old enough to remember the magic of those old German tube radio's? I realize Twl is talking about WAY better fidelity, but still............there was a simple unfettered magic in the sound.

Makes me wonder, anything wrong with wanting to have fun with this as well as listen. I wouldn't mind a smile on my face as I spun my favorite LP.
Albert: I had the pleasure of attending a local "single driver" get together a few weeks back (hosted by Thor over @ the single driver website). I arrived rather late and did not get to listen to everything, but the overall coherency of sound of the designs that I did audition was quite amazing, as was the separation of voices and instruments.

Yes, @ 47 years old I remember the sound of many radios and stereo consoles that used single drivers or coaxial/triaxial speakers with a single point source. My father had a pair of Stephens Trusonic coaxial speakers (big ones) mounted in the ceiling of our basement rumpus/game room. Oddly enough my first single driver project may be based on a smaller version (8") of the Trusonic's.

Bruce Edgar was @ the event, which also got me thinking of some of his smaller horn designs (don't think that our room is big enough though).
No, no, NO, twl! You've missed my point completely. And you've gotten defensive, which was NOT what I wanted.

You and I have been through this before. If the composer didn't want you to hear pitches below 40Hz then s/he would not have written them. So by definition, dear friend, when you truncate the audio spectrum you are choosing to listen to something other than what the composer intended you to hear.

This has nothing to do with how technically or musically literate you may be, as I think you very well know.

It is borne in upon me yet again that nearly any sort of attempt at this kind of discussion will be overwhelmed by ideological pronouncements cast set forth in the language of martyrdom or righteous wrath. Very wearying.
