Compresion driver shoot out. I want to offer a few options in the high end system designs i create. I will do this over the weekend my shop and post my thoughts of this comparison. Both companies have thier product readily available for me to use in my systems www. Last edited by soundmanshorty : at PM. Mistick Krewe. Sounds like a fun comparison. Isn't the JBL 1.

Beryllium is also expensive because it is a very complicated and toxic material to work with. Considerable extra steps have to be taken in its production which raise the overall price of the product. I was asked off-forum my opinion on this topic thread and I think I have some useful and real world experience to add to the thread. This JBL driver is used in the Vertec system. This system is known as one of the harshest rigs out there.
There have been many sound companies that have tried the TAD drivers only to revert back to whatever they started with. I personally know a company in the Bronx that has a closet full of TAD drivers. When Meyer was using JBL components, they would only accept out of a hundred delivered.
Keep in mind that JBL products for the most part these days are Asian imports, either in whole or the components. I've auditioned the BMS co-axial drivers in depth compared directly to other drivers with other people.
The ND is an un-believably clean and accurate driver that is capable of high output to a very low frequency with no distortion or clapping of the diaphragm. When other drivers reach their limit, these drivers just keep going. The has a sensitivity of DB. Listen to the drivers only. The design is a dual ring radiator it's two compression drivers on one throat and backplate reflections are all but eliminated.
Impartial evaluation is an absolute requirement. From a BMS user: Why do they sound better? BMS has developed and patented a unique, domeless diaphragm with less mass than a traditional diaphragm, remarkably reducing diaphragm excursion and inertia.
It has exceptional dynamic range and produces even the most complex musical signals with depth and definition. BMS drivers require much less energy than conventional diaphragms, allowing a much higher SPL, less dynamic compression, an increase in transient response, and lower harmonic distortion than traditional designs.
With reduced excursion and excellent transient response, BMS drivers react extremely quickly to peak level signals and have high crest factors. The result is an increase in dynamic headroom and precise definition. Because of the increased sensitivity and lower distortion, much lower crossover points can be used. With more of the frequency spectrum coming from a single point, the quality of sound is more focused and less smeared. The BMS neodymium drivers offer a more defined sound than the ceramic drivers.
This is a function of higher flux density and less flux variation. Last edited by pbellsound : at AM. Find all posts by pbellsound. Ultimately, none of that would matter anyway if the exit horns are arrayed side by side with their coverage overlapping. Are you refering to the stacks at G Spot? I've seen those pictures and wondered how that setup worked with out getting alot of comb filtering.
Is this how they test comb filtering in germany? Find all posts by atf Find all posts by duron tarik. You would not hear it in that video becuase the camera dose not move around the room.
Comb filtering gives un even coverage, something that you can not hear in one spot. I am not sure I get what you are trying to say. What is the video supposed to show? The compressed audio in that video dose not have the ability to reveal anything relevant to the question about comb filtering.
