| How important is the efficiency of a speaker to you? But to "composite" a square wave from sine waves would take sine waves way up into the ultrasonics and where would that put the slew factor??? A Hammond uses exactly the technique to which you allude. But it never achieves anywhere near a true sq... | |
| How important is the efficiency of a speaker to you? The whole article flawed because it is based solely on the use of sine waves. I don't know about you, but I listen to more than sine waves (and possibly flutes). But square waves, sawtooth waves, and complex waves have "verticle" (i.e., instanta... | |
| How important is the efficiency of a speaker to you? "I’m sorry, but your understanding of slew rate and how it applies to how an amp operates is simply incorrect. Slew rate describes how fast an amplifier is capable of changing, not how fast it is changing. It describes the maximum rate of change, ... | |
| How important is the efficiency of a speaker to you? "an amp operating withing it’s specifications that is producing 100 W RMS at a given frequency will reach peak power in the same amount of time as a 1 W RMS amp will." You missed the point. I said ALL OTHER THINGS BEING EQUAL. So the same amp,... | |
| How important is the efficiency of a speaker to you? A high efficiency speaker takes less watts to drive to the same volume level as a lower efficiency speaker. ALL OTHER THINGS BEING EQUAL... If a speaker is 10 dB louder than the other, it takes 1/10th the power to drive to the same volume level. ... | |
| Subwoofer speed is in the room, not the box In another vein, yes a small sub is "faster" than a larger sub at the same volume level. Ultimately the volume is directly related to the volume of air moved. Because a smaller cone must move further to displace the same volume of air as the larg... | |
| Subwoofer speed is in the room, not the box If you put the mains through a capacitor that was not previously there, what does that do to the overall phasing of the drivers, including the mid and high that now have an additional capacitor in their circuit? What influence would this have on ... | |
| Harbeth vs Graham audio I have original Chartwell LS3/5As (with an extra NOS woofer) but my room is big and I like to listen at realistic levels. They sound beautiful in small spaces and at low volumes..., relative to the room. I could probably turn them up but don't w... | |
| Drag on driver causing noise Sometimes a voice coil rub can be mitigated by turning the speaker over (i.e. rotating it 180 degrees). If they are small, perhaps you could try rotating the cabinet to find a position where this doesn’t occur, then re-mount the woofer to this pos... | |
| 3-4 dB dip at crossover region: what should I listen for to hear it? Probably. Each shape of horn will have its own set of peaks and dips. | |
| 3-4 dB dip at crossover region: what should I listen for to hear it? As I said, dips in the upper midrange are characteristic of the breed when using horns. JBL 4348: 4345: 4355: 4333 (L300 pro equivelent) I have a pair of L200 modified to L300 specs and the dips drive me crazy. I don’t even l... | |
| 3-4 dB dip at crossover region: what should I listen for to hear it? The depressed upper midrange is no stranger to JBL professional monitors all the way back. Some are worse than others. | |
| 3-4 dB dip at crossover region: what should I listen for to hear it? The range in question is above the fundamental pitch of most singers and it is the overtones that add "brightness" to the sound. Perfect example. Listen how her voice (maybe guitar too?) is a bit more "laid back" with the JBLs. | |
| 3-4 dB dip at crossover region: what should I listen for to hear it? With a dip of that magnatude in that area, you will hear a "dullness/flatness" in the vocals as though the overtones are subdued. Many JBLs suffer from this. | |
| Led Zep Fool in the Rain Maybe not a shuffle (actually a swing), but just gotta love the drums on this one: https://www.youtube.com/watch?v=jMGeqRxzykA |
