4 ohm taps on an 8 ohm speaker
Hopefully Al **will** chime in. But in the interim, much has been written about this subject. Before I go off the techno-babble deep-end here, let me say that I am dubious that trying different output taps will harm a tube amp. In most cases the c...

Ngjockey and Bombaywalla ... I find the issue of phase coherence to be intellectually interesting. I also find Roy's article and the article Ng... provided to be equally interesting. If I had the time, if there were more B&M stores around with...

Ng... thanks for the phase coherence article. The article seems to be based on scientific controlled studies and tests. Rather than paraphrase the conclusions, I copied them here:"So what conclusions regarding the audibility of phase distortion ca...

Excellent comments gents. I'm hoping Al (Almarg) and Ralph (Atmasphere) get around to reading Roy's articles and sharing their comments. Although it has been said many times, designers of audio gear take into account many features and do their bes...

Bombaywalla, I'm somewhat familiar with NRC test facility. But I am not sure which of the NRC tests speaks to time and phase coherence. Btw, I surmise that the reason many of the top speakers, like the Magico Q5, that have flat frequency response ...

Just a supplemental fyi, here JA's bench test measurements for the Revel Salon 2:http://www.stereophile.com/content/revel-ultima-salon2-loudspeaker-measurementsAnd one more, the might Magico Q7:http://www.stereophile.com/content/magico-q5-loudspea...

Al and others, take a look at John Atkinson's step measurements of the Revel Studio 2:http://www.stereophile.com/content/revel-ultima-studio2-loudspeaker-measurementsJA notes that "the speaker is time-coherent rather than time-coincident: each dri...

Sounds_real_audio -- your comment re placement if the drivers is interesting. There are some brands that stuff drivers every-which-way into the front baffle. One brand that comes to mind is Nola. I wonder how the Nolas manage the time and phase co...

Ok ... if Tim or Bombaywalla catch this, here the ultimate Q. How can one tell whether a speaker is time and phase coherent? Critical listening? Reviewer comments? Bench test? If critical listening is that important, the real challenge for us is, ... 
Sloped baffle
Tim, although I don't understand the science, I recall reading that a sloped baffle is one component of achieving phase coherence. The proper cross-over order (1st, 2nd, and so forth), plus maintaining a specific listening position, plus, setting ...

Psag, I don't think the last couple of comments posted before your comment (mine included) deviated from the OP's question about sloped baffles. I say that because sloped baffled may be used to address (in whole or part) issues relating to using m...

Thanks Tim. I'm listening to a HD CD of Dave Brubeck's, "Time Out." Perhaps I'm just used to listening to sonic swill, but the imaging is more than satisfactory and the music is quite enjoyable. My fronts are Paradigm S8s (v3), with beryllium twee... 
Sloped baffle
Bombaywalla, I have a follow up question. How are small speaker manufacturers able to design speakers without the benefit of the R&D budget, engineers, and testing facilities that some of the larger manufacturers have at their disposal. For ex... 
Sloped baffle
Bombaywalla ... I read as much of the discussions as I could before falling asleep at 1:30am in the morning. No surprise ... the physical science is way over my head. But I do have some take-a-ways that I would like to share. As a threshold matter... 
Sloped baffle
Bombaywalla, ... that;s for the links. I started reading into the threads. This is very complicated stuff. And I thought getting my arms around amp and speaker compatibility was tough. Speaker design is a beast. I will return to these threads over...
