What makes one woofer handle more power than another?? Most voice coils are made of the same material are they not? I know some coils are bigger than others. Also what makes one motor structure more efficient than another. I mean they are all pretty much the same design.
More power...um thickness of coil...how much wire is used...not all are made of same material. Woofers are rated for thermal power handling...so the cooling of the motor and voice coil is crucial for increased power handling. You can have a huge voice coil but in a crappy designed motor structure with no venting and it will burn up quick...and have a smaller coil in a well designed motor structure with good venting and heat dissipating abilities and it will handle good power all day Efficiency??? depends on moving mass, voice coil gap (I think), suspension stiffness...hell I dunno much about efficiency
Broad question really!!!!! Power handling wise........... the voice coil is the "motor" of the speaker, it is what makes the diaphram move back and forth, along with the magnet as the repelling/attractive stationary force so to speak. The power handling is deterined by the type of voice coil and its ability to "exhaust" heat from the thermal loads. What makes one woofer handle more power than the other? its adhesives, voice coil winding, its former, Is it edge wound, is it aluminum or copper...lots of criteria are dependant on its power handling.........THERMALLY!!!!! As far as efficiency, magnetic drive force, the compliance, or the stiffness of the suspension system of the cone, the magnetic gap, the design of the voice coil.....lots of things come into play for both criteria. But yes, prettymuch ALL speaker designs are the same in the most basic element, they move air..... the ideal speaker would handle virtually unlimited power, with a moving mass of ZERO...its thermal and mechanical limits would be unlimited.....but this wont happen....at least not in our lifetime!!!! Hoe that helps answer your question....
Has anyone seen adire audios Parthenon subwoofer with 175mm of peak to peak excursion??? crazy lol THATS 6.8 INCHES PEAK TO PEAK...OR OVER HALF A FOOT OF EXCURSION lol http://www.realmofexcursion.com/videos/Adire/parthenon.1.wmv
I have seen that before....For frequencis below 40 or so Hz it would be great!!!!! but in reality the amount of power that it takes to drive such a mechanism is too much.. the mechanical stresses, inertial mass, and the "lag" of the motor/cone strucure would be too great for any real application in car audio..... But would make one HELL of an sub for a home theatre that needs to reproduce a earthquak!!!!!!!!!
