| 15" vs 18" subwoofer - which to buy? Sean....I did not get to rerun the test last night when background noise was low. Maybe tonight. I am quite sure that the background noise is the reason that the plot becomes nonlinear at low level. By the way, the data looks too perfect over much... | |
| Review: Behringer DEQ2496 Equalizer Suits_me...In a digital system, quantization error (Plus or minus half a bit) is the same for small signal as for large, so if you express it as a percent of the signal it is maximized for small signals. Just to be "Fair and Balanced" hum and nois... | |
| Biamping; Amps w. Different power ratings? Douglas_schroeder...Loudness is determined by the GAIN of the amplifier, not by its power rating. (GAIN is volts-out per volts-in). A 20 watt amp may play louder than a 200 watt amp, up to the point where the output reaches 20 watts (very loud).No... | |
| Biamping; Amps w. Different power ratings? Piezo...1. With regard to the peak/rms (voltage) ratio, this would be 1.414 for a pure sine wave. High frequency waveforms are more jagged than low frequency, and the "spikes" will go much higher relative to the rms. Suggestion...look at some wave... | |
| Biamping; Amps w. Different power ratings? Piezo...If Peak is your concern, the High frequency amp is more critical, because the peak/rms ratio is higher. I know that "everyone knows" that the LF amp needs the most power. And that includes VTL. It used to include me until I actually measur... | |
| 15" vs 18" subwoofer - which to buy? SOME DATASignal......SPL..-67.......50..-52.......55..-45.......60..-40.......65..-35.......70..-30.......75..-25.......80..-20.......85..-15.......90Both the electrical signal and the SPL were measured, in units of dB, using my two Behringer DEQ2... | |
| 15" vs 18" subwoofer - which to buy? Sean...Mechanical losses are actually thermal in nature, like the electrical loss in the voice coil. In neither case is there any mechanism for a "threshold" to be overcome. But rather than debate, I will make some measurements. | |
| HELP for Tinnitus It would really be wonderful if tinnitus proved to be caused by a fungus, and therefore treatable. This reminds me of stomach ulcers which all doctors knew were caused by excess acid due to stess, until an unknown Aussie doctor found he could cure... | |
| What are the characteristics quality recordings? As Timf says, the sequence of selections can be very important. This is most evident in the area of Classical music. How would Mozart's Jupiter symphony go over if you played the movements in reverse order? | |
| 15" vs 18" subwoofer - which to buy? Sean...Other than compression at some high level of SPL, I can't think of a reason for a low SPL "knee" in driver sensitivity. Can you provide any further info/references?Equalization that is SPL-dependent is another one of the tricks that the ubi... | |
| Biamping; Amps w. Different power ratings? Piezo...I am sure you do "use significantly more power on the bottom end than on the tops" and for your live pop concert application I am easy to convince that this is right. My point is that your situation does not translate directly to the home ... | |
| HELP Which wall of new room to put system on? If it is a new room, and WAF is not the determining factor, why not try it several ways and see what you think. One setup that I have heard, and which is rarely if ever mentioned is a diagonal arangement, where the speakers are not against any one... | |
| Biamping; Amps w. Different power ratings? Until recently I would have agreed with Gregm about using the higher power amp for the low frequency. However, in my system, where, for each channel, a stereo amp drives high and low frequency drivers, the power required for the low frequency is m... | |
| 15" vs 18" subwoofer - which to buy? Rives...I don't understand your comment about "inertia". The effect of cone mass does not have any threshold to be "broken". If the parameter were "friction" what you say would make sense, but a cone driver has no friction, just mass. If sensitivi... | |
| Is SACD a dead format? Bigtee...Yep. I also am "sentimental to those great years of audio" when I, as a college student could afford a SOTA system. The equipment was often built, not in someone's garage, but on our own kitchen tables. |
