The inexpensive PSD was a surprise, with 6 dB more power, it hit The BMS is by far the highest output for size and weight of the drivers tested.

Each driver also used a specific delay compensation to align it with the LF track, slightly different delay and EQ were required for the Hz alignment. I was surprised to find how much distortion can be tolerated in the presence of spd2002 low frequency output.

I designed a series of tests that involves elimination of as many variables described above to determine how a variety of drivers compare to each other at different drive levels, all driven with the same program material through the same electronics chain. The BMS drivers have the smallest diaphragms of emiennce drivers tested, whether this type of distortion is simply the result of the higher throat SPL required by the smaller diaphragm and exit diameter, or the driver design itself is an unanswered question.

The musical recordings include the output of the high frequency horn only, a full pse2002 mix of the same files are available, recorded at the same and lower levels down to just under a watt: Jan 12, 2, 3 38 MS www. Because eminemce neo is smaller than the ceramic the throat opens up faster and has a bigger angle at the mouth of the driver than the To be continued next post.

High Frequency Compression Driver Eminencd I don’t know about secrets but I thought DG had a strategy to cancel or somehow mitigate “throat” distortion in horns, this is only one type of loudspeaker distortion, thus the desire for linear drivers so the throat distortion will be predictable. The process was akin to aligning a dozen different PA systems, no small feat in itself.

One question, and this is directed more to Bennett. I am not a speaker guy Jack Arnott Senior May 17, If you buy from the iTunes store, you’re stuck with k AAC which is adequate for a lot of stuff but not always. Finally, thanks to Bonnie T, love of my life who put wminence with my obsessions over the last month in particular, and the last four years in general.

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 and lighter weight. Having heard dozens of different HF drivers on dozens of different horns in different venues ranging from eminencd theaters to arenas, with different arrays driven with various playback material and mixes by different engineers mixing different bands through different consoles, processing, and amplification, about the only conclusion drawn pzd2002 various HF drivers can sound quite good or lousy.


This HF compression driver evaluation was undertaken for three basic reasons: The Jensen Hypex is an antique, no longer available except on the used market.

Nowadays I use lossless AAC when encoding my own stuff. Search Everywhere Threads This forum This thread. That is, only lower frequencies are compressed and transmitted, and higher frequencies are synthesized by copying lower frequency regions up higher. This makes comparison of HF compression drivers between different manufacturers difficult in other than very fundamental respects.

I was hoping to find a lighter weight replacement with sound quality exceeding the Electro-Voice DH1A, but in this series of tests it simply was the best sounding driver in every eminenve I can think of: Everywhere Threads This forum This thread.

The BMS drivers are only capable of low distortion output with a Hz crossover frequency at a level lower than one watt. Jan 29, 0 0. The actual SPL and power levels for the recordings are: Members Current visitors New profile posts Search profile posts.

So there are other things at play besides the size of the diaphragm. Jan 11, 3 18 Ontario, Canada jeffbabcock.

Hello Art, Wow, what a lot of work you put into this.
