Bronze Member Username: SoccerPost Number: 30 Registered: Apr-04 | This is just me wondering in my ignorance: if a speaker is getting to a too low impedance, what pros and cons would there be in inserting a say, 2-ohm/150W resistor? The goal is stop the impedance from going below 2 ohm... TIA |

Gold Member Username: GlasswolfNorthWest, Michigan USA Post Number: 2388 Registered: Dec-03 | the impedance of the speaker is a fixed calue. just match the amplifier and speaker(s) when you buy them. don't bother with the resistors. |
|
Bronze Member Username: SoccerPost Number: 39 Registered: Apr-04 | Yes, but if I put the resistor in series, the amp would always see at least 2 ohm, yes? On the other hand I'm afraid of what it can do to overall sound... TIA |

Gold Member Username: GlasswolfNorthWest, Michigan USA Post Number: 2392 Registered: Dec-03 | impedance isn't a fixed value. it's nominal, and a complex value. remember at or near driver Fs the speaker can drop to as low as .33 ohms at higher frequencies, it can jump up to as high as 100 ohms. you have to remember damping factor, the inductance introduced by the driver itself, and so on. if you really want to stablize the load and make it more or less a flat resistive load, build a zobel network for the driver(s) |

Gold Member Username: GlasswolfNorthWest, Michigan USA Post Number: 2406 Registered: Dec-03 | the zobels are easy to build but remember to use non-polarized electrolydic capacitors of a sufficient rating. most caps are polarized so these you'll need to get from a company like www.pac-audio.com they carry the coils, and resistors, too. Zobels are really handy for flattening out the resistive load on subs. They do wonders paired up with aperiodic subwoofer enclosures which serve the same effect. |

43DumbAssQuestionsAndStillGoing........WhataShame Unregistered guest | I beg to differ joao. A stupid question is one that is not thought out with common sense before it is asked. Like all of the questions you have asked so far. |
|
Bronze Member Username: SoccerPost Number: 44 Registered: Apr-04 | ok, but to define common sense, one must first be hold of knoledge... |
|
Bronze Member Username: SoccerPost Number: 45 Registered: Apr-04 | which in many cases ain't my position... and i'm not ashame of not knowing everything... |
|
Bronze Member Username: SoccerPost Number: 46 Registered: Apr-04 | surely if someone said that aircrafts don't fly alone, i wouldn't call him an idiot... different subjects, different people, different knowledges. cheers |
|
Bronze Member Username: SoccerPost Number: 47 Registered: Apr-04 | But ok, since i'm not at you guys level, in the future i'll try to post really difficult (for me) questions, instead of easy (for you) ones! TIA! |
