the spikey bits of the plug move up and make a sound wave out the horn. Air Motion Transformer (AMT) Using a folded thin film diaphragm with aluminum conductors that are formed similar to an accordion squeezebox, this tweeter's diaphragm is placed between opposing magnets.

Compression Driver Vs Tweeter

End of Topic 2 Written by John Burnett Created: 09-Dec-2008 Horns Horns Compression drivers Large horn systems ◀ ▶ Contact © 2008-2016 Lenard Audio. An older circuit protection technique used by Electro-Voice, Community, UREI, Cerwin Vega and others is a light bulb placed in series with the driver to act as a variable resistor. All of the idiosyncrasies within the compression driver are further magnified by the horn flare, making compression driver design one of the most exacting tasks in professional audio.

If the horn is to short you get comb filter effects (look at my sim pics at off topic).

Compression Driver Horn Design Understanding Compression Drivers: Phase Plugs by Phil Graham in Speaking of Speakers on 11 November, 2012 Print Email View Comments Over the past three issues of FOH, we have covered many A big "soundwall" around the hornmouth smoothes (?) this effect. http://www.fohonline.com/home/73-speaking-of-speakers/7799-understanding-compression-drivers-phase-plugs.html Dome Villchur's invention is still the most common tweeter type; probably about 95 percent of all speaker systems use dome tweeters.

I understand they have a diaphram; like a mini speaker cone right??? Compression Driver Vs Bullet Tweeter Here the phase plug also plays an important role. this is fascinating. Quad, MartinLogan and Final Sound are among the few electrostatic speaker brands.

Compression Driver Horn Design

In the Hanna and Slepian proposal the compression cavity is directly connected to the throat of the horn. http://education.lenardaudio.com/en/07_horns_2.html The throat and horn work together to make an acoustic transformer that couples the diaphragm to the listening room. Compression Driver Vs Tweeter But the real world leaves plenty of room to build high performance designs with both. Midrange Compression Driver slot radiator bum tweeter bullet tweeter Compression tweeters are approx 106 - 110dB/m/W efficient. 50 - 100 Watt Compression tweeters have always been

This can result in changes to the coverage angle, or to variations in the sound intensity across the wavefront in the horn. his comment is here CLP $ Ingresa el precio mínimo a CLP $ Ingresa el precio máximo Formato ver todoFormato Todos los anuncios(seleccionados) (1 315) Subasta (18) ¡Cómpralo ahora! (1 300) Ubicación del artículo Predeterminado Sólo EE. Some very high-end speakers use ribbon tweeters and well-known companies such Aurum Cantus, Fountek and Raven manufacture them. Modal anomalies from the diaphragm that are transmitted through the phase plug will also influence the wavefront as it enters the horn. Compression Drivers For Sale

The modal behavior causes local variations in the production of sound within the diaphragm. It is certainly electrically more efficient, but significantly more expensive to produce. A good dome tweeter can be made for a manufacturer's of about $5, though some high-performance tweeters from companies like Scan-Speak and Dynaudio can cost as much $300 to $400 on http://vocollectapp.com/compression-driver/compression-drivers-how-they-work.html This change significantly improves the transducer response as the effect of the acoustical resonances in compression cavity is reduced.

In addition, the compression driver makes the device much more efficient, so it takes less power to reach a certain SPL. Jbl Compression Driver They can be thought of as similar to hifi dome tweeters in that they have a dome diaphragm and a motor. The dome is very fragile and should not be touched.

With a compresion driver the dome is inverted and phase is in relation to the phase plug.

As with electrostatic tweeters, the absence of any magnetic motor and voice coil-induced distortion and very light diaphragm allow for transparency and resolution.

Permanent installations only. Other than its use of electromagnets, Thuras’ creation would be readily recognizable to modern pro sound practitioners as a compression driver (Fig. 1).

and Slepian, J. [1] were the first to discuss the benefits of using a large radiating diaphragm with a horn of smaller throat area as a means of increasing the efficiency So why is this, which works at even higher frequencies, seem to revert to 'normal' speaker technologies that I do understand. Sound from the centre of the horn passes through unhindered. Wave-length 18in / 440mm. 1in and 2in refers to the throat diameter of the horn.

They were Klipsch ref 28'S. Applying the same rules as we did with the dome tweeter, we can get 118 - 123 db output at the listening position, but this is far more than we need.
