Surely the power handling is just a measure of what the voice coil can take before it starts overheating and failing, and not necessarily anything to do with the mechanical limitations of what the driver can achieve.
Some top of the range active speaker boxes with dedicated internal LMS often push drivers beyond their 'published' RMS power handling, as they have fine tuned everything for optimum performance. FBT often take B&C drivers and run them well beyond published power handling with no noticeable drop in sound quality. Edited by Andy Kos - 28 June 2012 at 1:08am |

hahaha, you know I love you to bits Mykey, but..... ...when people are discussing a design or configuration of speakers you do have a rather annoying habit of turning up and showing off! Posting some cryptic photos or tantalising plots of a cab you have designed that out performs whatever is being discussed. LOL in all seriousness, I realise most of these are commercial designs and you couldn't just share the plans. But a few more details/tips/ideas about how you work your magic would be a huge help for us in the cheap seats who don't have the experience and skill you do k |

600W driver will have larger/longer/thicker voice coil. High power drivers and efficiency are a contradiction in terms. Tradeoff between efficiency & driver strength is needed. 4x MT121s, with half decent drivers (FANE/PD/Eminence/Celestion), easily covers 500+ people. When I say easily, I mean 2x per channel of a QSC RMX 2450, and volume pots were at 10 o'clock. Apparently people were dancing to the music 1/2 a mile away, and even though stack was in Broadwater Farm Tottenham, system could still be heard in Wood Green, not bad for 1x 4x scoop stack.

For the most part this is true. Especially noticable in car subwooder drivers, where the "arms race" of being able to say your driver handles a billion watts more than the competitor, but the sensitivities are pants for exactly this reason. However there are a few exceptions. BMS do the 12n810 (think thats the right code ) doing 600w at 100db and eighteensound do a few but most noticeably a very cost effective ferrite driver that does 600w at 102db that I'm VERY interested in at the moment for some MT-130 style cabs. So yeah it is possible, but as Lev says these are few and far between. k Edited by kevinmcdonough - 29 June 2012 at 2:23pm |

It all depends what you want to achieve. If you put 1000W driver that id 98bb but able to go down to 100Hz and cut it at 600Hz to a BMS4592 coax MF/HF then you get a lot more advantage.

Yep. If you have the budget, for the desired driver selection, then go for it. Some of us in UK go for "bang per buck solution", which means PD in MT121, strong driver, high SPL, cheap price. |

Yes but funny thing is that PD is only cheap in UK. Here i can get it for almost 20% more then the BMS 12 inch which is by far more superior then the PD.
