They're fairly common. Several companies sell them, including one in Seattle. Wierd that Googling "orthodynamic speaker" or "orthodynamic loudspeaker" turns up nothing. I get 37 hits - maybe you need a new ISP? :-) Ah, I was searching on them as a phrase rather than as either word appearing independantly. Looked at all 37 and the word seems to be used a fair bit but not defined often. Two sources indicated that orthodynamic and isodynamic are a distinction based on how the force is applied. They both say that orthodynamic is when it is applied to a single point (or ring) and would encompass cone and dome speakers. They say that isodynamic drivers are those that have their whole surface driven and would encompass, electrostatics, magnaplaner and ribbons. The audiophile use is vice versa with orthodynamic meaning surface driven. Bob -- "Things should be described as simply as possible, but no simpler." A. Einstein |

Here's one:
http://www.newformresearch.com/ Not even in their glossary. Is "orthodynamic" just another name for "ribbon."? Only from their point of view. They're not the same thing. A ribbon is pure metal -- it has no backing. I've never heard the Newform speakers, but if they're properly engineered and executed, they should be very good. |

"Stewart Pinkerton" "Phil Allison" "tony sayer" ** The ESL 63 / 988 is highly phase ( time ) coherent and uses 8 independent panels. Production units are tested in the factory against a calibrated reference unit using 1 kHz square wave drive.

Yes that is very impressive;) How many moving coil designs could do that.... ** None - when you include both the good square wave and close frequency / phase matching. Bull****. ** Kindly post evidence of another speaker that passes the *same* out of phase matching test the ESL 63s do. I will not hold my breath. Although phase-coherent dynamic speakers went out of fashion in the '70s, there are still quite a few around. ** The phrase back then was "time aligned" - ie drivers mounted on stepped baffles.

"Stewart Pinkerton" "Phil Allison" There was at least one post that put them down as "Chinese" speakers having nothing to do with Quad. http://www.quad-hifi.co.uk/lseriesworks.htm According to Quad, all parts are designed "in-house". ** Yep - "in house" means in Shenzhen, China - where the Chang brothers factory is located.

"Margaret von Busenhalter-Butt" wrote in message ... Also anything in your size/price range from Avalon Acoustics. The Eidolon Diamond is arguably the most transparent dynamic speaker in existence. Margaret However, the upper crust Avalons feature instrument placement that is pinpoint accurate in a way that cannot be replicated with any ES (or other speaker) that I know of. Some people like it more than others. And as far as the soundstage is concerned, the Avalons can match the width but not the height of really good stats. OTOH, no stat (or other speaker) that I know of can match the soundstage depth of the better Avalons. Cheers, Margaret |

"William Sommerwerck" wrote in message ... Orthodynamic speakers -- ie, a conductor on a flat plastic substrate. What!??? They're fairly common. Several companies sell them, including one in Seattle. Basically, they're ribbons backed with Kapton, Mylar, etc. (A true ribbon is a pure metal strip, with no backing.) The backing eliminates the ribbon's fragility and adds mass that lowers the driver's fundamental resonance. The classic Infinity EMIT and EMIM drivers are orthodynamic. The drivers in Apogee speakers are orthodynamic, not ribbon (except for the tweeter used in the Diva and one or two others). There have been orthodynamic headphones, such as the Yamaha YP-1 [sic] of a few years back. Orthodynamic drivers have much of the "speed" and low coloration of electrostatics. Having owned Acoustat Sixes and Apogee Divas, I actually find the latter to be (subjectively) more accurate -- and the Sixes were hardly chopped liver. Hi William, Do you still have the Divas? If not, I'm curious to know what speaker bettered them... Cheers, Margaret |

I misread your post. I thought you were asking how Quad's ESLs compared to Proac, Dynaudio and Spendor. I like all four brands' dynamic offerings, but couldn't live with any of them. I just don't get on with dynamic speakers for very long, no matter how charming they are at first. There was at least one post that put them down as "Chinese" speakers having nothing to do with Quad. They're made in China, but were designed in the UK. In the case of the 988s, it's just a refinement of the 63, using better quality transformers (designed by Andy Grove), better stators (higher copper quotient) and a much-improved frame for holding it all together. The 989s are identical to the 988s except for two extra radiators on the last delay line. : Make room and get some used 63s. :-) I have thought of that and not quite given up yet. However, it does run into hard limitations, like my wife's opinion, room size, why we must live in an urban situation, etc. Divorce, knock down walls and combine rooms, etc. Always ways around these problems. :-) -- td |
