The main difference between 2 Pole Motors and 4 Pole Motors is that 2 Pole Motors have a single pair of magnetic poles whereas 4 Pole Motors have two pairs of magnetic poles. also eigentlich kann man immer 4 polige speakonbuchsen verwenden, ab du die 2+,2- pole belegst ist dann abhänging vom verwendeten lautsprecher (zb. I have just purchased some new 4 pole speakon cables and need to rewire them. Due to speakON's mating mechanism arcing is prevented and electric shocks cannot happen. All info ive found only gives examples and info on 2 pole. In a 2-pole (single pole pair) motor the poles are spaced so that the rotating magnetic field makes a complete 360 degree rotation every phase period of the mains cycle. 2 pole motor has higher NPSHR as compared to 4 pole motor. oder wenn du zwei chassis in einem gehäuse hast, und sie getrennt ansteuern willst, … Alot of extension cables are using 3.5mm 4 pole male. I will be using 2 amps in bridge mode ( 1 amp for each speaker ). Hi, I am purchasing an extension cable 6 inches long for my earphones. Q: Will a 2 pole speakON connector mate to a 4 Pole connector? Gareth Walton wrote on Fri, 24 October 2008 06:44: Furthermore, a 4-pole filter = 24 dB/octave slope and that's because 6 dB x 4 = 24 dB. doppelschwingspulen subwoofer). A: Yes the two-pole line connector will mate with the four-pole panel connector connecting to +1 and −1; but the reverse combination will not work. 2 Pole Motors vs. 4 Pole Motors. 2 pole motors are cylindrical whereas 4 pole motors aren’t; In 2 pole motor design access to cooling air is less whereas in 4 pole motor symmetrical cooling with proper control of hotspots due to its design. This means a 2-pole filter = 12 dB/octave slope and that's because 6 dB x 2 = 12 dB. Thanks. I just want to make sure I won't lose any sound quality or anything. The speakON cable connectors are the industry-standard connectors for amplifier / loudspeaker connections. The entire family of 2, 4 and 8 pole cable connectors has been designed to operate in high current, inductive load environment of loudspeakers. A motor is a device that transforms electrical energy into mechanical energy in the form of torque supplied through a shaft. Q: How do I wire a speakON cable? Will the 4 pole extension work fine? 2 pole motor has better noise performances as compared to 4 pole motor. If you halve the pole spacing the field only rotates 180 degrees. I think my current earphones have 2 poles. To understand what is meant by the terms 2-pole filter and a 4-pole filter, you first need to know is that the word "pole" in the context of filters refers to a 6 dB per octave roll off.
