Enhance your home audio experience with the Carver Cinema CRM-2 Ribbon Speakers. These bookshelf speakers, with a sleek design, produce clear and powerful sound. They are wired for connectivity and were manufactured in 2010. The Carver CRM-2 model has been highly sought after by audiophiles, and its not hard to see why. These speakers have been well-maintained and are in excellent working condition. Theyll make a great addition to any home audio setup. Above is the AI description - I couldnt resist. Heres mine: These are serious speakers. Cost new for the pair in 2009 was $2,500. Capable of handling up to 400 watts of power each and they love it. I used these in a 2 channel - 300 W per channel system with a 15 JBL subwoofer with dedicated amp. The ribbons fire forward and are very clean and pure - lots of detail without any harshness. There are two smaller 4.5 in. speakers on each side of each speaker. This fills the room and gives a great deal of width and depth to the sound. I understand these were designed for a high end surround sound system but they worked great as a two-channel system -especially with a subwoofer. They arent big - about 8.5 tall, 5.5 wide and about 6 deep. They are solidly built weighing a little under 10lbs each and have a beautiful rosewood finish. For what I am asking, I doubt there is anything that would come close in quality and sound reproduction. They are very classy looking, powerful and yet take up very little room. They work perfectly and are in extremely good condition. Any blemishes in the photos are just dust. There are no scratches.

SUNFIRE CRM 2 ABDECKUNG SATZ 3-teilig für EINEN Lautsprecher. Sehr guter Zustand! NUR ABDECKUNGEN! Wie auf den Fotos. Die 3 Abdeckungen für EIN Sunfire CRM 2 Lautsprecher. Zustand neuwertig! Abgebildeter CRM 2 Lautsprecher IST NICHT TEIL DER AUKTION!! SUNFIRE CRM 2 covers (3 piece) for ONE Sunfire CRM 2 speaker! COVERS ONLY! As on the photos. The 3 piece covering for one speaker in basically unused condition. As new! The CRM 2 Lautsprecher on one picture IS NOT PART OF THE AUTION!!

SUNFIRE CRM 2 High-end HiFi Stereo Lautsprechern (Schwarz) in sehr gutem Zustand! Technisch einwandfreier Zustand; kann sehr laut spielen aber bei uns kam das selten vor. Die Sicken an den kleinen Bass Lautsprechern sehen aus wie neu. Fotos!! Ribbon hat einen sehr schönen Klang. DIE ABDECKUNGEN SIND NICHT DABEI ABER SEHEN SOWIESO BESSER AUS OHNE! Optisch: Normalerweise Rosenholz aber diese total überempfindliche Oberflächen waren ziemlich voll mit Oberflächenkratzer und manche Ecken waren leicht verbeult also habe ich ca. 12 Stunden Zeit investiert und die Gehäuse wieder hergestellt und schwarz lackiert. Keine Profilackierung aber sehen jetzt viel besser aus als vorher!! Das Rosenholz war sowieso so dunkel dass man es kaum gesehen hat außer in Direktlicht. In schwarz finde ich sie fast besser. Original Verpackung ziemlich mitgenommen aber dabei. Anleitung ist nicht mehr vorhanden aber die muss man lediglich anschließen. Der kleinen Schalter ist für Wand nähe oder Freistehend. Die Etiketten müsste ich neu machen weil einer nicht mehr lesbar war. Diese Lautsprecher sollte man in einem Surround System benutzen und sind durchaus mit anderen Lautsprecher typen kombinierbar! Über den Surround Receiver sollte man den ab ca. 80 Hz laufenlassen. Kann man auch mit Sunfire Subwoofer laufen lassen oder als Mittel / Hochtoner einsetzen mit hochwertigen Großen Bass Lautsprechern. So habe ich sie eingesetzt. Letztes Foto mit Tannoy Gold! Der Ribbon ist zum Bespiel BESSER als der Tannoy Hochtonerteil in Sache Auflösung und weniger verzerrt! Diese kleine LS sind nicht zu unterschätzen! Hervorragender Klang und Pegel fest! Gerne werden Fragen geantwortet!! SUNFIRE CRM 2 High-end HiFi Stereo Lautspreakers (black) in very good condition! These are in perfect working condition with no issues!! Amazing very clear sound for such a small speaker. These were not designed for the full sound spectrum but as Satellites for surround systems from about 90 Hz.Should be used in a system with large front speakers or / and subwoofer for best results. You can also use a pair of these with a subwoofer for full sound spektrum and amazing stereo imaging. The covers are not included!! But they look more interesting without them anyway. Original packing included but in pretty bad shape after decades in the basement :-( Optically these no longer have the original finish! The insanely sensitive Rosewood finish had so many surface scratches that I decided to sand them down and paint them black. Not a profi paint job but pretty good (photos) and they look pretty good now. I actually like them better in black. The Rosewood finish was so dark it could hardly be seen anyway. Please look at the photos to see what you are getting! The sound is truly high end and amazing!One of the best mini speakers on the planet I would dare say. Shipping to European Union 33 Euros

Sunfire Cinema Ribbon CRM-2BIPW? On-Wall Bi-Pole Surround Sound Speaker (White)Open-Box, Mint conditionSame Bark...More Bite Since their introduction, the Cinema Ribbon line has forever changed the notion that small boxes cant deliver the luxury of premium, audiophile sound. Now, this already legendary XT Series line gets an important addition that also makes it more versatile than ever before. First, its a purpose-built, on-wall surround speaker thats a perfect timbre match to any model in the existing Cinema Ribbon line. Its also the only bi-pole speaker on the market to feature the benefits of dual, side-firing ribbons. At 400 watts per cabinet, the deliberate location of each pair of these high output ribbons create the wide diffused rear sound stage so important for todays soundtracks and multi-channel music. This fact is made more remarkable when you consider the CRM-2BIPs ultra-slim 3-5/8 deep profile. Its one of the lowest profile on-wall surround speakers of any type; as much as 50% slimmer than any comparable speaker.Features:Dual high output 6 ribbons for a total of 20 of Kapton® material4.5 High Back-emf woofer with Trifilar voice coilGloss black lacquer finishPower handling: 25-400WFrequency response: 80Hz - 40kHzSensitivity: 90dBImpedance: 6 ohms (nominal)SpecsIntelligent Tweeter Shaping™ for precise ribbon output adjustmentLow-profile, 3-5/8 deep cabinetGold-plated binding postsEasy key-hole mounting with included templateIdeal where listening locations are close to side and rear walls, yet high-power output and a diffused sound is required.Dimensions: 12.18 x 8.25 x 3.63 (WHD) (309 x 210 x 108 mm)Weight: 8.0 lb (3.6 kg) Check out all my items on the audiolab-outletBe sure to add me to your favorites list!

SUNFIRE XT CRM-2 High-end HiFi Lautsprecher Rosenholz in gutem Zustand! TEXT LESEN!! Technisch 100% absolut einwandfreier Zustand; kann sehr laut spielen aber bei uns kam das selten vor.Die Sicken an den kleinen Bass Lautsprechern sehen aus wie neu! die Ribbons haben einen sehr schönen Klang. Ich habe sie immer wieder umgestellt um verschiedenes auszuprobieren am Anfang und deswegen Optisch leider viele feine Oberflächenkratzer die man allerdings nur unter direkter Lichteinstrahlung sieht. Schwer zu fotografieren. Von Vorne und Oben noch sehr gut! (Fotos!) Es waren bei einem Lautsprecher unten auch ein paar kleine Beulen drin; die könnte ich ziemlich gut ausbessern so dass die kaum noch sichtbar sind. Die Kratzer sieht man in Betrieb sowieso eher nicht wenn sie an ihren Platz stehen.Manche Flächen habe ich mit Klarlack nachlackiert wegen den Kratzer aber nicht alle Flächen. Sehen auf jeden Fall wieder Wohnzimmer tauglich aus. Fotos anschauen!! Original Verpackung sowie Anleitung vorhanden aber die Abdeckungen fehlen. (sehen sowieso besser aus ohne)Den Lautsprechern sollte man in einem Surround System benutzen und ist durchaus mit andere Lautsprecher typenkombinierbar! Über den Surround Receiver sollte man denen ab ca. 80 Hz laufenlassen. Gerne werden Fragen beantwortet. SUNFIRE XT CRM-2 High-end HiFi speakers Rosewood in good condition! Please read the text before buying!!! Technically 100% working condition; can play very loud but we never really turned up the volume much.The surrounds on the small bass speakers still look like new! The ribbons have an amazing clear and accurate sound! At the beginning I moved them around a lot to experiment and they had quite a lot of fine surface scratches. Difficult to photograph. (See Pictures!) There were two small dents on the bottom of one speaker. I was able to repair them so that the dents can now hardly be seen. The scratches etc. can only be seen under direct light. When they are in their playing positions you would hardly notice them. The top and fronts sides are actually still very good. Some sides were re varnished so they are actually looking pretty good all round. I always try to descibe things as accurately as possible. See pictures!! Original packaging and instructions included but the speaker covers are missing. (look better without anyway)The speakers should be used in a surround system with a subwoofer. For best results the Surround Receiver should be set so that these speakers run from 80 Hz upwards. Feel free to ask any questions.
