Compression Driver Theory


Also, once you get past about $150.00/speaker the law of diminishing returns starts kicking in hard and the cost for "better" SQ is not linear to the actual SQ improvement. Reason: needed to add a phrase 2nd November 2010, 07:59 PM #2 Racket Scientist diyAudio Member Join Date: Jan 2010 Just to add one more comment - Set up #1: EMP e5Ti, e5Ci, and EMP e5Bi surrounds, Outlaw LFM1 Plus sub, SVS NSD SB12 sub, Marantz Slimeline 1504 AV receiver Set up #2: Def Tech SM450, CLR2002, SLS Higher frequencies for a given horn tend to "beam" more (become more directional) than conventional drivers. Check This Out

The formula below shows that either increasing the modulus (E) or lowering the density (ρ)will raise the speed of sound in the material. A large driver may have a 4in diaphragm and the sound compressed through the phase plug to the 2in throat opening. Lobeing was limited to the highest frequencies only.

Compression Driver Vs Dome Tweeter

But the real world leaves plenty of room to build high performance designs with both. It also offers efficiency for low powered amps many of us enjoy. The horn I am presently using is less than optimum. The advantages are...

Check date values in: |date= (help) ^ Wente, E.; Thuras, A. (March 1978 (originally published 1928)). "A High-Efficiency Receiver for a Horn-Type Loudspeaker of Large Power Capacity (reprint)". 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. The larger the exit size on a compression driver the lower the maximum high frequency will be. Compression Driver Protection I just find that the low end compression drivers are hard to listen to (entry level Klipsch, etc), so if I am going to buy cheap speakers, I would prefer a

Introducing the Econowave speaker Update: After hearing some Econowaves and various driver and waveguide/horn combinations, I have found that not all drivers and waveguides ... Compression Driver Vs Bullet Tweeter The ear becomes more sensitive at this level, so any problems are heightened. The largest dome is 4in in diameter. http://www.fohonline.com/current-issue/73-speaking-of-speakers/7799-understanding-compression-drivers-phase-plugs.html Ordinary radiating drivers do not usually meet the requirements of a compression driver, so you cannot just horn load a normal cone speaker.

Compression tweeters are rarely used because of cost, and consumer demand for systems to be small. Compression Drivers For Sale Please consider donating to help us continue to serve you. They are just designed with excruciatingly careful detail.

Compression Driver Vs Bullet Tweeter

Modal anomalies from the diaphragm that are transmitted through the phase plug will also influence the wavefront as it enters the horn. http://www.diyaudio.com/forums/full-range/176518-compression-driver-horn-full-range.html Just looking over specs on some compression driver horns and realized that with the 2" drivers some apparently go as low as 400 Hz. Compression Driver Vs Dome Tweeter It is against the backdrop of these modal behaviors that the transducer designer must create a phase plug to bring sound from the compression driver diaphragm to the driver’s mouth. Midrange Compression Driver Traditionally professional sound systems are not designed for fidelity.

Ahh sorry I missed the context. The Econowave works by using a one inch compression driver that can handle power lower down in frequency than most and pairs it with a horn that loads to that frequency...

Triad uses a horn loaded AMT tweeter in the top of the line cinema reference speaker. Horn Driver Speaker To understand the benefit, it is helpful to imagine water rippling in a bathtub. The reverse side of the dome is inside a compression chamber.

Driver Protection For active systems, Compression drivers and compression tweeters must not be connected directly to the amplifier.

Different compression drivers can perform with great variability on the same waveguide or horn, depending on the shape of the wavefront they emit. Typically, the compression driver designer desires the speed of sound in the dome to be as high as possible, as this means sound vibrations will reach the center of the dome The vertical slot causes the water or paint to be spread horizontally. Jbl Compression Driver Wave-length 18in / 440mm. 1in and 2in refers to the throat diameter of the horn.

The resistance of the bulb filament is proportional to its temperature which increases as current flow through the filament increases. Learn more Special Deals! Compression drivers have come a long way, but still fall short in comparison to the best hi fidelity tweeters. http://vocollectapp.com/compression-driver/compression-drivers-uk.html Such a refined top end. ______________________________________ Home Theater: http://www.avsforum.com/forum/15-gen...sement-ht.html NWCgrad is offline Quote post #12 of 20 Old 04-11-2015, 07:38 AM Eyleron AVS Forum Special Member Join Date:

Getting distortion lower, faster transient response ("temporal distortion"?), while retaining high sensitivity, power handling, and able to maintain controlled directivity across a wide band would be a holy grail! They found that the bandwidth of the transducer could be extended to higher frequencies using their phase plug. List of DIY speaker designs Most audio enthusiasts are smart enough to let someone else do the design work. The waves travel across the surface at a defined speed, reflect off the walls of the tub, and soon form a pattern of standing peaks and valleys across the surface.

These devices are typically known as “phase plugs.” Phase plugs, like horn flares, have many intricacies and are subjects of ongoing research in professional audio. The only way to tell if they are for you is to get out there and listen to multiple speakers that employ them. slot radiator bum tweeter bullet tweeter Compression tweeters are approx 106 - 110dB/m/W efficient. 50 - 100 Watt Compression tweeters have always been A simple and essential test for a horn is to put it to your ear as an acoustical telescope.
