Compression Drivers How They Work
Planar ribbon tweeters do not require any matching transformers or wall outlet power. Maybe it's because i spent my life listening to dome tweeters (which suck imo... The modal behavior causes local variations in the production of sound within the diaphragm. I've been reading about the planar magnetics, AMT, Wisdom Audio, etc. Check This Out
Where speakers can be redundant (i.e. and that makes the sound ??? It’s important to understand that vibrations in the dome take time to travel across the dome’s surface, just as sound vibrations in air take time to travel to the listener. The largest dome is 4in in diameter. https://en.wikipedia.org/wiki/Compression_driver
Compression Driver Vs Piezo
It is because of a movie at a theater that I started my exploration of horned speakers in the home years ago. Ribbon tweeters have been known for extremely airy and transparent sound. I have no idea why.
There is really no debate. It works in a "compression" mode; the area of the loudspeaker diaphragm is significantly larger than the throat aperture of the horn so that it provides high sound pressures. Learn more You're viewing YouTube in Russian. Compression Drivers For Sale this is fascinating.
Only guessing here. Compression Driver Vs Bullet Tweeter Skilled designers have made choices to use both types of phase plugs, as well as changing the number, spacing, shape and path of the slots that lead from diaphragm to the Forum Jump: User Control Panel Private Messages Subscriptions Who's Online Search Forums Forums Home Articles AVS Forum® Articles Community Articles Contest Terms & Conditions http://redspade-audio.blogspot.com/2010/12/what-is-compression-driver.html Usually if you go this cheap, you only get metal dome tweeters that produce a whole lot of annoying top end harsness, or there's something else sloppy about the sound, or
Waveguide shootout Jump to the next Waveguide Shootout > In one day we compared a bunch of compression drivers and waveguides. Horn Driver Speaker Air radiation resistance to the diaphragm becomes nonlinear and the diaphragm is physically stressed with excessive movement at high power and can easily fracture. I have read many threads on the compression drivers like the recent "4344MKII and 275ND problem" and ones on how you should not test there ploarity with a battery etc. Horn-loaded compression drivers can achieve very high efficiencies, around 10 times the efficiency of direct-radiating cone loudspeakers.
Compression Driver Vs Bullet Tweeter
Horns, especially the waveguides used for line array systems, make important assumptions about the nature of the waves that enter them. http://www.fohonline.com/home/73-speaking-of-speakers/7799-understanding-compression-drivers-phase-plugs.html Check date values in: |date= (help) ^ Wente, E.; Thuras, A.

Damn...............company scraped idea! http://vocollectapp.com/compression-driver/compression-drivers-uk.html Reply With Quote 10-22-2004,12:57 AM #7 Mr. Is the very best compression driver better than the very best direct radiator? Good suggestion. Compression Driver Horn Design
Unlike your 2425s this model has an alnico magnet (3) that is inside the cast housing/magnet return casting. These old horns can still be seen in a very few old cinemas and museums. I have 4 TD12S in boxes still waiting on something to match. http://vocollectapp.com/compression-driver/compression-horn-driver-work.html For circular and near circular horns a lens was the most effective means to increase horizontal dispersion without introducing lobe distortion and minimal loss of efficiency.
The ring has an inherently higher mass break point than a complete dome which allows it to run out to a higher frequency. Jbl Compression Driver K-horns are awesome! @Gooddoc 's JBLs are insanely good. This led to the selection of stiff (i.e., high elastic modulus) and lightweight dome materials.
My question is on the ring radiator series - I've never had one open, but from pics I've seen of the diaphragm it looks like there's a hole in the center,
If Adam Audio had actually started their in-wall version of the GTC 88's.............I would have used GTC 88's and their in-wall version of same speaker. Triad uses a horn loaded AMT tweeter in the top of the line cinema reference speaker. The model that I own is the 5, which is a little bit bigger and more powerful in comparison.) nvidio is offline Quote post #17 of 20 Old 04-11-2015, 08:22 Compression Driver Protection Many pro sound speaker manfs.
The large formats are typically a 4 " diaphram 2" throat and the 1" are 1.75 to a 1" throat. Power compression will rob some of that output by as much as 5db at the full rated power, but we can expect less for short bursts. Diy horns can be superior and better than 99% of the standard commercial offerings. navigate here They correctly surmised that this arrangement results in a significant increase in the radiation resistance (and therefore increased efficiency), because the loading mismatch between the vibrating transducer surface and air is
In the best case scenario we only just make it to the target and it's likely that the tweeter will struggle. This phase plug consists of concentric circular rings that allow sound to enter the phase plug at a few discrete points across the diaphragm surface. Plasma can be generated either by gas ionization by high-voltage electric fields (corona discharge) or by burning gas at a very high temperature. So you have the best of both worlds - the extension of a small light piston and the power and efficiency of a very large transducer.
The only way to tell if they are for you is to get out there and listen to multiple speakers that employ them. Additionally, errant reflections in the phase plug can bounce their way down the horn flare. All Rights Reserved Worldwide. DIY Transmission Line Speakers Update: I'm now offering crossover upgrades.
The intervening 85-plus years have seen compression drivers split into two major design categories. The slots direct sound from the dome diaphragm to the small opening (throat) which couples to the horn. This level of engineering can no longer be justified in our modern world of high profit and low cost. wow that 2405 with the 'crystal' tongue looks hot.
