Romy, may be the alnico jbl 2482 + aluminium diaphragm (plastic surround) would suit for your application here. I tested such driver on 200 hz tractrix horn and worked fine. Went down well under 200 hz and is 2" throat. It is heavy but I would be usi...

YL 75000 has heavy phase plug indeed ,  rca style (see sketch) while 1250 ( I never had one) gets a fixed metal dome equivalent  to spherical piece on 75000 and rca  plugs without conical shape pointing the exit of throat. Ironi...

From the perspective of pumping of atmospheric pressure the ALE bass drivers might be more capable transducers. It or might not be so as well. To get 40Hz at 110dB in 5” it would take some excursion.  I am sorry but you can’t bend the law o...

I do not completely agree with you. You see, I do not feel that stressing of “physics and geometry“or “scientific concepts” leads to anywhere. In fact I generally do not feel that knowledge itself worth a lot. I value much more a presence of a co...

Battling horn criticism is the very same thing that battling audio superficiality, lack of serious criteria about audio and ignorance aboutthe phisics and geometry  involved. The really annoying thing is that audioworld was ,in his early developement...

In fact, digital recording allows the industry to  process easily every musical material (a very powerful exchange-tool). Unfortunately, digital recordings  are also highly corruptible  in the musical-expresive potential  as you point...

Romy,i Would state that any  digital vs analog discussion  must take place only in context of recording  of musical material, not within the world of music reproduction itself.  be it analog tape or computer media,raw recordings (let´s call it...
