    FRANÇAIS (English below) : Une paire de Filtres JM LAB FOCAL 2 voies, issus dune paire denceintes JMlab Cobalt CC800 Ces filtres sont en excellent état et fonctionnent parfaitement. Entièrement III fabriqués en France III par FOCAL-JMlab à St Etienne (La Talaudière) Spécifications : - Condensateurs Polypropylène JMlab- Selfs à air JMlab- Nature du câblage : Cuivre pur (OFC)- Fréquence de filtrage : 2200 Hz - Plaque blanche- Dimensions (L x l x h) : 120 x 120 x 32 mm- Poids (pièce) : 404 g Les 4 lamelles de connexion plaquées or pour la mono-amplification sont fournis (photos 01 et 09). La double amplification est possible en les retirant. Filtre OPC™ (filtre à phase optimisée)Le filtrage est un élément clef dans la conception dune enceinte acoustique. Son rôle et sa mise au point sont complexes, la personnalité de l’enceinte en dépend. Le rôle du filtreLe filtre a pour fonction de répartir le signal en provenance de lamplificateur entre les différentes voies constituant lenceinte acoustique : grave, médium et aigu. La coupure la plus critique est sans aucun doute celle qui concerne le raccordement du médium et de l’aigu. Un filtre passe-bas coupe la réponse dans les fréquences élevées du médium. Un filtre passe-haut coupe la réponse dans les fréquences basses du tweeter. Dans la réalité le filtre est utilisé également pour corriger les défauts de linéarité des haut-parleurs. Le raccordement (la coupure) intervient généralement entre 2000 Hz et 5000 Hz. La technologie OPCCes démarches constituent le fondement de la technologie OPC. Il serait illusoire de parvenir à cet idéal en ne travaillant que sur le filtrage. La maîtrise totale de la réponse des transducteurs n’est possible que pour les fabricants développant eux-mêmes leurs haut-parleurs comme c’est le cas pour Focal-JMlab. Des transducteurs spécifiques sont conçus pour chaque nouveau développement. On ne corrige pas électriquement un défaut mécanique. Avec la technologie OPC, nous conjuguons ainsi des réponses offrant une atténuation effective de 36 dB/oct. pour les pentes des sections passe-bas et passe-haut, ceci avec une différence de phase nulle entre ces deux sections. À l’écoute, cela se traduit par une grande cohérence de timbre due au fait que la zone d’émission simultanée des deux transducteurs est très étroite en fréquence. Dautre part, nous offrons une image sonore tridimensionnelle d’une vérité saisissante, avec de surcroît une faible directivité, la position du point d’écoute n’est ainsi pas critique. III CONCEPTION ET FABRICATION 100% FRANÇAISE IIIConception et développement en France : Ces filtres ont été conçus et développés en France par les ingénieurs Focal-JMlab dans le laboratoire de Recherche&Développement. Ils ont été fabriqués à la main, dans latelier de Saint-Etienne. Tous les produits Focal haut de gamme subissent un process de contrôle tout au long de la chaîne de fabrication afin de garantir leur qualité acoustique exceptionnelle.

Works perfectly. Totally Hand III Made in France III by FOCAL-JMlab at St Etienne (La Talaudière) Technical characteristics :- JMlab Polypropylene Capacitors- JMlab air chokes- Type of wiring : Pure copper (OFC)- Filtering frequency : 2200 Hz- White board- Dimensions (L x W x H) : 120 x 120 x 32 mm- Weight (unit) : 404 g The 4 gold-plated connection strips for mono-amplification are provided (photos 01 and 09). Double amplification is possible by removing them. OPC crossover™ (Optimum Phase Crossover)The crossover is a key element in the design of a loudspeaker. Its role and its development are very complicated, the personality of a loudspeaker depends on it. The role of the CrossoverThe crossover has the function of distributing the signal from the amplifier to the various drive units in a loudspeaker: bass, midrange and treble. The most critical area of filtering this signal, with out any doubt, is between the midrange and treble. A low-pass filter rolls off the higher frequencies of the midrange. A high-pass filter rolls off the low frequencies from the tweeter. This crossover point generally occurs in the region between 2000 - 5000 Hz. OPC TechnologyThese aforementioned steps form the basis of OPC technology. However, it would be naive to think that this ideal could be reached simply through an extensive development of crossover technology. It is necessary to have total control over the response and performance of the transducers themselves, as is only possible for a few manufacturers who develop their own drive units as Focal-JMlab: a specific drive unit is developed for each individual type of product. Its unrealistic to think that a mechanical deffect can be corrected electricaly. With the OPC technology, we use an acoustic roll-off of 36dB/Octave for the slopes between midrange and tweeter along with a perfectly aligned phase. This translates into a sound that is extremely coherent and with a natural timbre. Imaging is extremely precise and at the same time dispersion wide so that the result can be enjoyed over a wide listening area. III DESIGN AND MANUFACTURE 100% FRENCH III Design and development in France :These crossover were designed and developed in France by Focal engineers in the Research&Development laboratory. Theyre manufactured in the Saint-Etienne workshop.All high-end products undergo a control process throughout the production line to ensure their exceptional acoustic quality.
