Best new loudspeaker

i find it hard to believe that dispersion is the only variable accounting for differences in a speaker composed of cones as compared to a another speaker which has none of them. can you suggest a way of demonstrating this ?

It may be hard to believe but in the grand scheme of things when comparing 1000's of cones to all the panel/electrostats/ribbons out there then the radiation pattern is really what sticks out like a "sore thumb" as the one big difference overall.

Sure there are other differences and surely different transducer materials will make different spesakers sound different...but we are talking 1000's of speakers - so in general it is the raditaion pattern that is what remains markedly different.

I expect that Mirage or other omnidirectional or dipole speakers might be closest to the panel sound...although a large surface causes beaming in the forward direction (something cone speaker manufaturers try to avoid by using multiple sized cones for each frequency band) so perhaps horns (which can have a controlled directional sound) might be closer.

Perhaps Duke can suggest a speaker that you should try that will be closer to what you hear from panels - not that you may like it more ...but just to demonstrate that cones can be made to sound much more like large surface panels if configured in a certain way...

MrT, most Martin Logans are about 0.5ohms at high frequencies, usually starting out in the lows at 4 ohms. There are literally no tube amps made that drive loads like that without difficulty. Its not a presumption on my part- its just the way it is.

ML wants their speakers to work with transistor amps so they set the impedance very low. Unfortunately Quad has been following in their footsteps as has Innersound. Sound Lab used to do the same thing but seems to have realized in recent years that they need to moderate their impedances.

A point to consider:- what we are really talking about is neutral reproduction. If a speaker driver is truly neutral, its not going to matter if its made of cloth, paper, mylar or beryllium. It is simply going to be neutral.

I don't see how you can say you have no best in the face of some of your earlier comments in which a yardstick is created:

there is no best anything. however, at a point in time, one can say that given say 5 speakers, one of them is least inaccurate timbrally. that doesn't make it the best, but does establish performance in that regard.

This statement seems to have a contradiction. What am I missing?

hi ralph:

you are confusing facts, perceptions and value judgments.

if i say speaker a is less inaccurate than speaker b, the statement is a reflection of a perception. in order to say that speaker a is better than speaker b, there must be a criterion or postulate that says accuracy is better than inaccuracy. i never established such a postulate and i would never say less coloration is better than more coloration.

you continue to misinterpret what i say, perhaps, because you believe that accuracy is better than inaccuracy. such a statement is a value judgment. value judgments apply to better and best, best upon criteria or held beliefs about sound quality.

i believe that sound quality is personal and based upon preference. thus there is no better or best because what i prefer is neither good nor bad, it is just what i like. i do not attach any value to what i like. it is purely an opinion.

i have not an am notb contradicted myself. i have a fine command of the english language. years of college and graduate school and writing have refined my ability to communicate.

if you have any more questions, why don't we discuss this on the phone, or next time we meet at an audio show.

one more thing, i believe a martin logan speaker can be driven with a tube amp. i personally have heard a sequel driven by an early quicksilver amp which used 8417 tubes.

i do not believe that martin logan speakers necessaily dip to .5 ohms. can this be verified ?

Ouch. . . I seem to be hearing some smidgin of stridency emanating from the black backgroun. . . Is it mayhaps that darn Supraphon box with the Panocha Quartet again? Alas no. . . seems it's coming from a badly overdriven Sackbut struttin' its stuff in full cuivre! . . . I better engage that -3db treble filter on those Mahlers. . . This glare is driving me batty!

"since this experiement has not occurred you and i are engaging in probabilistic statements."

MRT, did you mean: "thought experiment"?
