In recent times, computing power has enabled horn designers to be very innovative, bending the laws of physics for shortening (truncating) horns, and increasing horizontal dispersion (constant directivity), with limited success A simple and essential test for a horn is to put it to your ear as an acoustical telescope. List of DIY speaker designs Most audio enthusiasts are smart enough to let someone else do the design work. No no no - the diaphragm/voice coil is the only moving part.

Midrange Compression Driver
For horns it's volume ueber alles - caveat emptor re the ultimate sound quality of horns vis a vis a direct radiator. With a compresion driver the dome is inverted and phase is in relation to the phase plug. DIY Transmission Line Speakers Update: I'm now offering crossover upgrades.

Longer wave-lengths than the horn length cause the diaphragm to move excessively. his comment is here The paper described the first generation compression driver with a field coil magnet and phase plug, It used aluminum diaphragm with an edge wound aluminum ribbon voice coil.

Ignorance and miss-understanding was and still is a problem throughout the professional audio industry. http://vocollectapp.com/compression-driver/compression-drivers-uk.html Compression driver From Wikipedia, the free encyclopedia Jump to: navigation, search A compression driver (cylindrical box at rear) on a midrange horn speaker used in a home audio system A compression
All rights reserved. Compression Drivers For Sale CDs vs domes A dome tweeter will typically have about 90 db sensitivity and wide dispersion. Horn Dispersion The on-axis response of horns can be flat but become directional as the frequency increases.
The amp will not clip at this point so we are in a safer region. Some were lead lined and sand filled. Basically you have a larger diaphram that goes through a phase plug to keep the path lengths the same to a smaller apeture/throat. Horn Driver Speaker Active options Considering the many challenges of passive crossover design, many DIY enthusiasts are running their speakers actively.
The net effect is that the filament consumes an increasing share of the total power thus limiting the power available to the compression driver. References ^ Hanna, C. This also has to be compensated for by controlling power (peak limiting) to the driver.

Warning The titanium dome diaphragm is very very very fragile and should not be touched. With a dome tweeter, the dispersion is controlled by the small size of the piston. 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. Waveguide shootout Jump to the next Waveguide Shootout > In one day we compared a bunch of compression drivers and waveguides.
The main physical difference is that the dome is coupled to an exit tube via a phase plug where the dome is large than the exit. The basic concept has not changed all the way back to the 30's if I remember my history right. The lens is no longer used.

In theory, 10w yields 100 db and 100w 110 db at this distance. Contents 1 History 2 Compression driver protection 3 References 4 External links History In 1924 Hanna, C. Perhaps due to less mass? 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.
They are much less expensive to build and to most people's ears sound better at the typical close listening distances used in near field monitoring. Constant directivity. The dome diaphragm unlike a cone cannot flex with excessive movement and fractures easily. Where speakers can be redundant (i.e.
