Art Welter Senior May 18, Jan 11, 2, 0 0 Land of Steady Habits www. Having one sitting idle after use in a Leslie-style rotating speaker, it has sat idle for the last decade, and psd002 an interesting glimpse into past designs. Also, in the same vein, there is less distance for the VC to support, or control at any one time.
Sminence Jensen Hypex is an antique, no longer available except on the used market.
Art Welter Senior May 16, Jan 11, 8 18 Florida. I wanted to eimnence the size of the drivers, einence relation to V oice C oil size. Granted distortion plots don’t necessarily relate to subjective listening tests but providing this data does help everyone make more informed choices. My point still holds water, that DG needs accurate linear drivers for his sundry corrections to work.
Examples of air non-linearity introduced by the mixing of two ultrasonic tones at dB SPL are available in posts of: The upward masking from lower frequencies crossover masks those distortion effects to a large degree. The musical recordings include the output of the high frequency horn only, a full range mix of the same files are available, recorded at the same and lower levels down to just under a watt: I could not resist quoting this Art.

Hope you find the recordings interesting, they offer an insight in compression driver comparison as far as I know never undertaken before this study. I was surprised to find how eminsnce distortion can be tolerated in the presence of the low frequency output. Jan 29, 0 0. Just that I want to thank her for her patience with you and this project. I hope this came out right.

One question, and this is directed more to Bennett. So the gentle reader has to sift through two layers and use appropriate filters for what I have to say. eminebce
Greg Cameron Senior May 17, So there are other things at play besides the size of the diaphragm. The low frequency ripple is less than the unit to unit driver frequency response variance. I use BMS drivers. If I am, please remove this post. Nowadays I use lossless AAC when encoding my own stuff. You must log in or register to reply here.
It was very interesting to me to see the two BMS drivers plots side by side. The process was akin to aligning a dozen different PA systems, no small feat in itself.
Granted it has much improved over the original mp3 format. High Frequency Compression Driver Evaluation 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.
Hope I’m not giving away any trade secrets here. What are benefits emimence adding HF driver 7khz up? 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.
In the past two decades, LF driver technology has made large advances in linear excursion capability and power handling, resulting in more clean LF output per driver, although requiring more power to achieve that goal. That is, psdd2002 lower frequencies are compressed and transmitted, and higher frequencies are synthesized by copying lower frequency regions up higher. And I am swamped with work at the moment, so will take a while to get to all the things I want to say here.
Who would have thought!? I’ll stop talking about stuff i shouldn’t be for now, at least in this thread. Drivers with more efficient, extended Psr2002 output would require less compensating boost.

Lot of thought here, and more so as the thread expands.
I am not a speaker guy And disclaimer, I sell them. HF air losses are in addition to the inverse distance 6 dB per doubling of distance. The distortion levels above do not include the minimal contributions of upper harmonics past the second, and are rounded to the nearest whole number above the actual 2ndHD.
I recall first coming to this realization years ago when making some DSP presets for some DIY biamped cabs and discovering that the HF driver with the lowest distortion level didn’t actually end up being the driver I liked best in the cab once it was put into the context of a full range cab. Michael Smithers Junior May 16, I’d also be very interested to follow a thread on masking in relation to drivers.
And the follow up conversations.
