That's pretty steep right now because I'm not certain that's the problem. Until then the ten DH1AMT and single DH1A drivers I own will remain in their present cabinets. Check This Out

I've never heard a more conventional audiophile system come anywhere close to this level of performance. http://www.audioheritage.org/vbulletin/showthread.php?16193-Compression-driver-distortion

The remaining Music recordings are in posts # 26 & 27. harmonics, unless they exceed the second, change THD very little. The slots direct sound from the dome diaphragm to the small opening (throat) which couples to the horn. Against marketing and popular belief compression drivers do not successfully produce energy above 6k - 10k Hz.

Opinions: Considering the disparity between size, weight, diaphragm material, and design, the constraints and compromises inherent in each approach, once equalized for flat on-axis response there was surprisingly little difference in Testing a 3.5" Tymphony TC9FD-18-08 "full range" driver on the Maltese horn, found that it had far less IM distortion than the best of the compression drivers, though is not capable Midrange Compression Driver kimbal Tubes / Valves 4 11th May 2009 08:05 PM Compression driver frequency response?

Sound Reinforcement Staging Subwoofer Power Production Recording Rigging Signal Proc. Compression Driver Vs Tweeter Changing shape from circular is a compromise that reduces efficiency and causes lobe distortion. The driver consists of a thin diaphragm which is placed about 0.02 inch (0.5 mm) from the phasing plug.

Figure 1: Details of a compression driver. Going further, I played some HF pure sine wave tones from 1 kHz and up through the B&C connected to the RCF active crossover and HF amp.

Logic recordings have been "bounced to MP3.

The smallest driver, the BMS 4552 had the least LF, followed by the 4550, the Jensen Hypex D-30, and the Eminence PSD2002.

B&c De82

Horns for sound systems are changed in shape to rectangle to increase horizontal dispersion. The PSD2002 is used as an OEM driver by many manufacturers, it provides fairly bulletproof operation. The lens was commonly referred to as a waterfall effect speaker. http://vocollectapp.com/compression-driver/compression-drivers-uk.html In comparison, a horn loudspeaker with a midrange compression driver efficiency of 25 to 30 percent will require as little as 10 or 12 watts of power input to produce the

When pushed hard, even with a 1250 crossover, the "s" sounds in the word "cities" seemed to get the most "spitty" with the BMS drivers, and the harmonics of the flute Ev Dh1a These drivers are rated to handle 110 watts each (75 with a square wave) and between 350-8000hz in frequency response.

The 30 second overall time varies slightly by recording as each start and finish time had to be cut to length individually.

or its affiliates v 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 Since that time, compression driver technology coupled with horn development advances have been in the areas of materials science allowing improvements in power handling capacity, lower distortion levels, and improvement of Bms 4550 All Rights Reserved Worldwide.

The time now is 07:11 PM. A simple and essential test for a horn is to put it to your ear as an acoustical telescope. The process was akin to aligning a dozen different PA systems, no small feat in itself. http://vocollectapp.com/compression-driver/compression-driver.html Ignorance and miss-understanding was and still is a problem throughout the professional audio industry.

Please consider donating to help us continue to serve you. The basic classic designs were done in an era when the task was to fill large spaces with plenty of clean sound from very little amplifier power. It appears to have an aluminum diaphragm with no phase plug.

Each driver also used a specific delay compensation to align it with the LF track, slightly different delay and EQ were required for the 1250 Hz alignment. It appears to me that although LF transducer technology has made some definite improvements in the past decades, HF driver design constraints have limited improvements to voice coil and diaphragm survivability Dual sine tests start at -20, about two watts of power, one watt at each frequency. Please add the address to your address book.

I dont know if its less power compression, and the headroom(at average listening levels for the home). In practise, a line source wave guide results in loss of efficiency as the frequency increases which has to be compensated for.

The Jensen Hypex is an antique, no longer available except on the used market. I found a replacement diaphragm (phenolic) for $26 + shipping, so two of them would run around $60. These same filters were used to reduce wind noise in the recording of the HF horn, the 30 Hz filter was inserted on the low side to result in a similar er..

Shipping to a APO/FPO/DPO? Using a conservative value of 20 dB above that level (well within the AES power rating) throat SPL will reach a level of 168 dB SPL. Above/right we see a section view, and next to it, a rear view. (click to enlarge) The voice coil at the edge of the diaphragm is immersed in a strong magnetic The wave guide attempts to convert the circular throat opening of the driver to a vertical slot (line-source) at the throat of the horn.

The B&C, also using a 3" diaphragm, was the next in terms of high output vs.
