Most 6.5 speakers do not really have mechanical excursion to allow them to handle more than 60-80watts if a reasonable high pass crossover frequency used. The ratings of 100watts RMS or higher are most likely thermal rating, but mechanical excursion/xmax power handling are more limiting. Some speaker manufacturers provide T/S parameters for their woofers (HAT, Infinity, and some others). I have played around with HAT Imagine woofer in WinISD (had to use 2sq ft to approximate IB, but it wasn't really sensitive to box size). 70-80 watts were more than enough to reach and exceed its one way xmax of 6mm with 80Hz crossover. Alpines I had are rated for 110watts but in reality handled even worse in real life power handling.</p></blockquote><p></p>
