Mostly money. Why do we still have SP/DIF standard in use even though it lacks the bandwith required for todays best formats? Legacy hardware. Licensing. Money...
You're partially correct. The impulse response affects some of the dynamics but does not reflect it. Electrostatic panels have an excellent impulse response but they're not perceived as too dynamic speakers (their dynamic sound exists in the upper frequency though). The speaker phase hasn't been...
If you're in your 50's or above statistically speaking you're not likely to hear anything above 16khz anymore. You may be able to detect some small harmonics on the lower frequencies. High frequency recordings are not a solution for anything since the limiting factor is always the analog side...
The air and sparkle in ESLs has little to do with frequency range and more to do with directivity (sound is dominated by direct radiation instead of reverberation), step response and dipole function. All dipole speakers have a more 'airy' sounds due to the delayed back radiation.
What's most interesting is that they were testing with CD:s which are sharply cut off at around 20khz. :greengrin:
Yes the 44,1khz sampling rate can in theory provide sound up to 22khz but because there are no perfect filters existing, most cd players cut off much much lower than 22khz in reality.
Maybe the JBL tech gave you pro amps which M2 are designed for. A bit of hiss is inaudible in a movie theater through the perforated screen and at a distance of several meters. Also since the M2 are probably designed to be played through the screen it would make sense that they're bright when...
I love the sound of a good horn speaker and this looks to be one. I have yet to hear one in person though. Unfortunately the Munich and Bonn High-End expos are also closed now for second year in a row.
Cool gear but I think you should consult a professional on a couple of details... At first sight I can see a couple of glaring problems:
1) Using hissing sounds to determine the need for acoustic treatment. It's a big no-no to treat only high frequency and leave the bottom end untouched. Your...
Keep in mind that both diaphragmatic and helmholtz are so called tuned resonators. They damp only a tuned frequency. That's why it's imperative that you measure your room first, determine the problem frequencies and then build / have built resonators to solve the problem. You might need several...
The problem with simple wool absorbers is that you need a quarter wavelength thickness of wool to have maximum absorption. For super low frequencies you'll want a diaphragmatic or helmholtz resonators.
