Externally moving the cone causes the voice coil to generate electricity. i have tube amp made by Jolida. L'impédance Z se définit comme le rapport tension/courant : Z = U / I. L'impédance des enceintes et des haut-parleurs est souvent de 8 Ohms (pour la sono et la hifi) et de 4 Ohms (pour les haut-parleurs de voiture). Most of the people might have experienced difficulty in hearing other sound in the environment where the person at the other end of the telephone calls from. If, however, you have a mid-fi or high-end amplifier or AV receiver—there’s no need to baby your system. I already have Yamaha NS P350(centre n surrounds, of 6 ohms impedance). ihave got one 6 ohm and four 3 ohm home theater speakers with me. In such a case a redesign of crossover filters should be attempted with shifting away their cut-off frequencies. With our speakers this happens in the field of 4-8 ohms.”. fallait pas mettre en série les twetters. Musical instruments and speakers share similar characteristics of the physics that governs tonal quality and sound colour. 2   8&Omega speakers in series is   8&Omega x 2 = 16R. The Samsung HT system is all rated 3 ohm. l'impédance des enceintes, je ne sais pas vu que je n'ai toujours pas compris The last part of our design protocol deals with impedance correction or compensation that many engineers also call impedance equalization. Idem quand je me connecte directement aux HP. Bien cordialement. Since the impedance is frequency dependent one should find the loudspeaker which provides the highest impedance at the operating frequency. Quant à enceinte plusieurs voies, il vaut mieux utiliser des HP d'impédance égale et le filtre aiguille les fréquences vers telle ou telle voie (l'ampli ne voit jamais les 3 voies en parallèle). En arrière du cabinet, j’ai The speaker has a voice coil in its construction, which is an inductor. The amplifier output transistors will get excessively hot and may/will fail. The material on this site may not be reproduced, distributed, transmitted, cached or otherwise used, except with the prior written permission of WTWH Media Privacy Policy | Advertising | About Us, The amplifier is a device which can source a current to the loudspeaker and every current sourcing device has an internal resistance and here it is represented as a resistance R, From the above figure it can be understood that even though the amplifier generates a voltage V, The value of the voltage drop by the same current across the impedances depends upon the value of the impedance and the value of the current flowing through them. Tks. I understand the difference between series and parallel, but I’m a little confused for when it comes to speakers. de l'ampli pourront-elles chacune alimenté un des kits 2 ou 3 voies en étant en Le danger réel dépend de la protection de l'ampli et je ne peux rien vous garantir. The Jensen is a big black box, that should be hidden away somewhere. Is this correct – If so all my speakers will be running in the (20/30W – 150-300W) perfect middle desired wattage range – except the surrounds that Max out at 150 @ 4 Ohms/ Parasound 5125 5-ch Amp says (185W @ 4 Ohms) so this is my real question concerning the watt rating match between the Parasound and The Martin Logan XStats – 1. do you agree that this is a correct summation? On se sent (un tout petit peu moins ...). For most people, a 6-ohm or 8-ohm speaker is going to be the norm. Cause that’s what I always thought. Est ce je branche en série ou en parallèle ou je laisse Tomber 200 W / 8 ohms En espérant que cela servira au-delà de ma petite personne, si vous daigner me
