COINCIDENT SPEAKER TECHNOLOGY
Coincident manufactures or has manufactured the following equipment click to expand models list :. The theoretically perfect audio component would sound like nothing. It would simply transmit the signal it is being fed with no alteration, enhancement, subtraction or distortion. Our goal with all Coincident models is for them to pass as much musical information with the least possible coloration.
Coincident speakers do not editorialize or attempt to glamorize the sound. For example, there is no intentional boosting of the midbass to provide the illusion of more bass, nor the rolling off of the high frequencies to make the resultant sonics more pleasing.
Coincident Speakers are designed to be as musically accurate as possible. We attempt to create an open window on the musical event, with nothing interfering between the music and the listener. Consequently, Coincident Speakers are very revealing of the musical source, the room in which they are placed and the ancillary components used. On the contrary, the better a component is at revealing the information it is sent, the more accurate and by definition, the more natural it will be since it will closer approximate the live music listening experience.
Those seeking to replicate the thrilling experience of listening to live music will greatly appreciate the "Coincident Sound. Coincident web site September : Coincident Speaker Technology was established by Israel Blume in for the sole purpose of creating a superior loudspeaker. Blume was ultimately dissatisfied with every loudspeaker he had ever owned or listened to. From the Quad ESL 63 to the Martin Logans, to Wilson Watts and almost everything in between exhibited sonic weakness that proved to be in the long term unacceptable.
Blume put his over twenty five years of audio and music experience to work to conceptualize a loudspeaker that would reproduce music with no obvious or distracting perversions. He understood quite well the inherent limitations of electrostatic designs, i.
At the same time virtually all dynamic systems possessed their own set of compromises, namely, slow transient speed, small image size, etc. Therefore, a new loudspeaker combining the best sonic attributes of cones and electrostatics had to be created. A daunting task to say the least. The first loudspeaker designed by Blume was the Concentric Monitor and its companion subwoofer, the Super Bass Monitor. What made this speaker unique was its cylindrical enclosure.
Unlike conventional cabinets, the Monitor was constructed out of computer cut MDF concentric rings. The advantages of this design was that its structural strength was typically 15 times greater than a prism shaped enclosure and furthermore rigidity was equal at all points. The fact that the enclosure was round also meant that internal standing waves were dramatically reduced. The Monitor also used the finest tweeter and woofer extant and in keeping with Blume's philosophy, the crossover was very pure and simple using only the finest tested components.
Many audiophiles and reviewers such as Frank Doris of The Absolute Sound were of the opinion that the Monitor system was one of the finest loudspeakers ever produced. However, there were three factors Blume felt he had to address before he could find acceptance in the marketplace with his dream speaker. Firstly, it had to more accessible aesthetically which many felt the cylindrical enclosure was not , secondly it had to be less expensive to build the Monitor was exceptionally labor intensive and finally the speaker had to able to be driven by single ended tube amplifiers which the Monitor could not.
The result of two years of design work culminated in the development of the Troubador speaker. Using extensive computer modelling, Blume was able to duplicate the sonic properties of a cylindrical enclosure but with the use of non parallelled flat plane walls. The most significant advantage of this type of enclosure is the elimination of internal standing waves. Three types of standing waves affect all previously manufactured loudspeaker enclosures.
The first and most powerful is the axial standing wave. The axial wave involves only two enclosure walls that are parallel to one another. Next in order of strength is the tangential standing wave which involves four enclosure walls that are parallel to one another. This type of standing wave has only half the energy of an axial wave 3db down. The last and least powerful standing wave is the oblique which involves six enclosure walls and it has only one fourth the energy of the axial wave 6db down.
How do standing waves degrade the performance of loudspeakers? A sound wave has a positive portion starting at 0 degrees to degrees and a negative portion starting at degrees. If the positive portion of the wave i. Likewise, if the positive portion of the waves meets another positive portion of the wave then the waves are in phase i. Likewise, at locations in the enclosure where the sound waves are out of phase one being negative and the other being positive the sound waves cancel each other out and no sound will be heard a low or no pressure zone.
The sonic result is uneven, boomy or sucked out bass response. The patented AWE asymmetrical wall enclosure eliminates the sonically deleterious effects of standing waves. In a further attempt to eliminate the sonic contamination of loudspeaker enclosures, Blume uses enclosure tuning techniques. Instead of using resonant enclosure materials and then attempt futilely to damp them out, all Coincident enclosures are constructed from inherently non resonant materials that need no damping.
The enclosures are then tuned to a high fundamental resonant frequency that is sonically undetectable. The culmination of this arduous, painstaking journey has yielded a series of loudspeakers that offer unprecedented performance in each price category.
From the Mini Triumph to the Conquest to the Millennium, Coincident speakers sound better and are better constructed than competing designs at the same price. Designer Israel Blume has recently realized his goal of building a true reference speaker that encompasses all the criterion he initially enumerated. That speaker is named the Millennium. This speaker is the most musically authentic loudspeaker in existence. It is capable of reproducing the musical signal fed to it with such verisimiltude that even a short audition will demonstrate this claim.

Discussion in ' Audio Hardware ' started by Benzion , Aug 3, Log in or Sign up. Steve Hoffman Music Forums. Location: Brooklyn, NY. Got mine a couple of weeks ago, but it came with one busted B, and it took close to 2 weeks to get a replacement. The tubes are Psvane Black Bottles - I was told they're phenomenal.

A loudspeaker or speaker driver , or most frequently just speaker is an electroacoustic transducer , [1] that is, a device that converts an electrical audio signal into a corresponding sound. The speaker driver can be viewed as a linear motor attached to a diaphragm which couples that motor's movement to motion of air, that is, sound. An audio signal, typically from a microphone, recording, or radio broadcast, is amplified electronically to a power level capable of driving that motor in order to reproduce the sound corresponding to the original unamplified electronic signal. This is thus the opposite function to the microphone , and indeed the dynamic speaker driver, by far the most common type, is a linear motor in the same basic configuration as the dynamic microphone which uses such a motor in reverse, as a generator. The dynamic speaker was invented in by Edward W. Kellogg and Chester W. Rice issued as US Patent 1,, Apr 2,

These two speakers are very similar in basic design philosophy, though their execution is quite different, mainly due to a decade's worth of improvements in dynamic driver technology. The PR is also unusually practical: It is flexible in the choice of both amplifiers and listening rooms. Since I obviously don't change my personal references very often, I feel it is necessary to discuss my basic philosophy on speakers. This will include the long-term history, and evolution, of my personal speaker references, plus the specific and detailed reasons why the Coincident Pure Reference has achieved its current status.

User Name Remember Me? Thanks Cyril! I've always wanted to listen to a pair of Coincident speakers. I bet they sound nice. I haven't heard them either but they are typically higher-than-average sensitivity and more importantly a benign load for tube amps, so are often mated with SET amps, although I would go with more than flea-powered SETs with these, something in the wpc.
Coincident Dynamo SE-34: SET amp with 300B's - initial impressions
I srael Blume, owner of Coincident Speaker Technology, contacted me out of the blue and asked me to review his Victory loudspeaker, just before the Home Entertainment show. But it was not a complete surprise, since I have raved about the Victory and Eclipse models in my previous reports of the Montreal and New York shows. What was really strange was that I had recently come within one phone call from buying a pair of the Victory from the same private owner who sold me his Plinius power amplifier several years ago. Someone else had just beaten me to them. I declined Israel's offer, since another writer had already reviewed the Victory, and I didn't feel there was an awful lot more I could add to that review. Let's just call them the "Partials".

If there is only one magician in this hobby, that is definitely Israel Blume. Very few manufacturers produces such a wide range of products with this success. Although he started business with speakers, now he is producing pre-amplifiers, power amplifiers, step-up transformers and cables.
How many of us have taken stock of our bank accounts and said, ah, it all went wrong the day I heard my first great sound system? Most of us will probably spend far more than we need to arrive at a point of equilibrium - if we ever do. Incorrigible gear flippers like myself might be beyond redemption. Then we would need to find an affordable DAC.
II is a significant improvement over the original PRE model. To be clear, with the majority of my recordings both analogue and digital , and during the majority of the time, I prefer the PRE II to my previous "Ultimate Reference":. Finally, I always make an effort to avoid repeating myself, but I am not able to improve on the conclusion of my original PRE review links above and below , so here it is, with some minor updates and edits:. I feel it is possible, and necessary, to condense the entirety of this review into two simple sentences, which are both personal observations and opinions:. Coincident is excited to announce that 8 years after its introduction, the Pure Reference Extremes are undergoing an update of significant proportions. The improvements include the following:.
Coincident Speaker Technology has just released several new tubed electronics components that will operate with loudspeakers of moderate-to-high efficiency. In response to customer demands Coincident is now introducing the Statement RC Remote Control Line Stage, which is identical to the Statement in every way but the following:. Though the new Statement RC Line Stage is designed to provide exceptional performance, well above its asking price, there is a subtle sonic compromise in comparison to the non-remote controlled Statement, as the transformer coupled volume pots of the Statement are the finest and slightly more transparent than the variable stereo potentiometer of the RC model.
remarkably, this is very valuable information
Of course. I agree with you.
