KEF KM-1
Beskrivelse av varen
Tilstand: Brukt
For salg har jeg disse svært sjeldne høyttalerene fra KEF. Disse ble utviklet for BBC Live til bruk i deres studioer. Når jeg kjøpte disse hadde de flere tekniske mangler som nå er utbedret. Bl.a. fikk jeg tak i noen mellomtoner og diskanter (https://www.ebay.com/itm/155716051675?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=WOEM7NeJT8a&sssrc=4429486&ssuid=Z0cUpTD0TIe&var=&widget_ver=artemis&media=COPY)
Forsterkere og elementer virker som sagt, men kabinetter trenger omsorg og kjærlighet. Jeg legger ved bilder etterhvert som jeg finner dem frem. De står utstilt i hifi&vinyl i Ski.

Her litt lovord fra en tidligere annonse. Dette er altså ikke ang mine høyttalere.
————
Imagine having an opportunity to own one of the actual James Bond Aston Martin DB-5 cars. For speaker,audio and studio geeks, owning these speakers might be just as rare an opportunity.
(Folks - these are so rare that we had a very difficult time valuating them, mostly because there isn't any recent sales history. Please offer your opinions on what you think would be a fair price. I would appreciate genuine, somewhat though-out opinions, not jokes and low-ball offers. However, if you are actually interested in them let us know what you'd like to pay for them.)
This is one of two sets thought to exist in North America, and one of a very small number manufactured by Kef to fulfill a need for a very high-output (pushing 120dB) studio monitor that also met the strict BBC requirements for neutral, un-colored playback, but at output levels impossible to achieve with other BBC monitors like the LS3/5A or other smaller BBC approved speakers.
As is fairly typical of Kef loudspeakers, these are precision engineered, perhaps OVER-engineered, to meet the robust requirements of playing at rock-concert volume levels while maintaining their requirement to be a "civilised loudspeaker". There are four 300mm/12-inch Bextrene woofers, each driven by its own 100 watt amplifier, two 110mm/5.25-inch polypropylene midrange drivers, with their own 300-watt amps, and one of the most amazing tweeters ever built - the HF-1 50mm/2-inch mylar dome tweeter, each one with a magnet more than twice the size of that used for the woofers in the speaker, and driven by an ultra-clean pair of 300 watt amps in a push-pull configuration.
To keep things cool, critical for the mid and HF units, the mids are each fitted to a 64mm aluminum bar, which is then coupled to a large aluminum heat sink, and the tweeter is ferro-fluid cooled. Further, "on-board analog computers provide information on voice coil temperatures to trigger protection at a pre-determined threshold'. The amplifiers and mid/tweeter modules slide out on locking rails for easy serviceability.
Listening impressions indicate that these have a sound very identifiable as Kef - that is, dead-on accurate, right down to impulse-accurate response with nearly ZERO added flavor or color. The bass, however, is breath-taking. Still accurate, but with the surface area of EIGHT 12-inch woofers, the dynamics are simply startling - like the Aston Martin's acceleration, the bass response will leave your jaw on the floor and your back pinned to your seat. VERY rare is the speaker that has limitless dynamics and absolute finesse in one package, and these deliver effortlessly.
Condition: These have been in storage for several years. The original owner passed away and these were obtained as part of his estate liquidation. The cabinets have significant scratching and some staining. A light refinish has restored them to presentability, but deep scratches and stains are still visible if you're standing close or are doing a close examination. We have posted several pictures of this close-up. Functionally, they operate nearly perfectly after rebuilding one of the mids and re-centering the voice coil in one of the woofers. One of the units exhibits a response anomaly, that being a dip in the mid range response, likely due to an aged component in the on-board active crossovers. We have equalized this out of the response in our listening room and they sound quite exceptional. If you should like to have this repaired previous to purchasing, we will obtain an estimate from a qualified technician. Cost is negotiable as part of the purchase price or a concession thereto.
Cosmetically we rate them 6/10, functionally 8/10. All user manuals, a service manual and circuit schematics are included. Our price is based on several factors including original price, but certainly the rarity and exclusivity of these remarkable speakers is a major consideration. They are best suited for studio or production monitoring, but can certainly be utilized as the left and right mains in a very high-end home music and/or theater system. Anyone who is fanatic about the accurate reproduction of music should consider these, especially of you want a speaker that is, without question, one of THE most accurate transducers ever manufactured.
Payment and shipping: we prefer cash, but other methods of payment are negotiable, all fees incurred will be payable by the purchaser. Local pick-up strongly preferred, but delivery to locations on the US West Coast ONLY may be negotiated. They break down into 4 parts plus the stands.
A personal meeting is required before we will be willing to accept any offers.
These speakers are offered as-is, and all sales are final, no exceptions. Included: All documentation, including operation and service manuals, schematics and second set of taller stands.
