The conical horn has much to recommend it and Bill can sell you these horns and accessories. Serious buyers do feel free to call. The room is heavily dampened, which seems to improve the ability of the large loudspeakers, horn loudspeakers at that, to work in a room this small. The field-coil technology takes this even further, as this magnet technology allows a driver to respond to the tiniest nuances with vanishingly low distortion. The driver requires both a signal, just like ordinary cone drivers, and an additional power source to energize the electromagnet, unlike ordinary cone drivers that use a large magnet. Buyer pays actual packing for the drivers and shipping costs. No, Neli doesn’t drop it!

The B-based monoblock tube amplifiers.
Get to avoid the therapist’s couch for a few more weeks anyway. Precision machining not available to compression driver designers in the early parts of the 20th century. The radial vogent are cut to great accuracy with a wire EDM machine, a difficult and expensive process.
These are, according to many horn experts, the best midrange compression drivers ever built by man. I do have a nice pair of 80 Hz mid-bass horns with drivers available to a buyer as well if desired.
The Iconic was introduced in ; the one in the photograph was built about Even with large horn 14288 in quite a nearfield setting — the listening chairs maybe six feet from the horn mouths — the drivers seemed well integrated.
After using them with 80 Hz folded bass horns, I es experienced the pinnacle of the hobby, and am now downsizing, cogeny. The turntable obviously has a highly modified arm – a work in progress we understand. Earlier this year at the factory where the parts of the field-coil coggent driver are manufactured on state-of-the-art Cogent-owned to keep the driver’s price down machinery [photo supplied by Cogent]. This is not where tubes do well. They are gorgeous and cannot be beaten in a midrange horn, by any other material, horn flare, or other technology.

Sorry, this listing has ended. This is two thirds of the eight most important octaves. The room is heavily dampened, which seems to improve the ability of the large loudspeakers, horn loudspeakers at that, to work in a room this small.
It is interesting that the system sounded as good as it did – certainly better than all but one or two systems at HE a few miles away – being as it was kind of heavily weighted in terms of quality on the speaker side. Note that there is a metal insert that mates the wooden horn throat to the driver opening completely smoothly. For a tweeter amp I think that the tube vs.
Our first project together was a pair of speakers with Great Plains Audio drivers. I can say that with complete honesty! After two years of self flagellation with these wonderful speakers, we got them finely dialed in and subsequently became bored. Buyer pays actual packing for the drivers and shipping costs. However, after listening to a variety of tube and solid state amplifiers I discovered that in some applications I prefer the sound of a solid state.
We got the impression that they were just tweaking with the tone arm for fun, trying out some ideas. I simply had to buy them to experience the sound.
Aside from the field voltages they are identical. Besides being one of the two principals in Cogent, Steve is also one de three co-founders of the Lansing Heritage website.
After careful listening to various crossover configurations I concluded that all crossover components have a surprisingly large, detrimental effect on sound. What a big heavy industrial-looking thing.
Cogent Field Coil Horn Speakers
cogrnt A close-up of the experimental tone arm. The drivers include a pair of Hz custom-made conical horns in gorgeous rosewood. The conical horn has much to recommend it and Bill can sell you these horns and accessories. The drivers have xs good output up to 12 Khz or so and can be EQed higher than that if desired. In October of my system received a major upgrade with the addition of some phenomenal horn speakers. Jonathan had collected quite a number of these drivers for use in the Oswaldsmill speakers he now offers for sale.
