Will High Power Amplifier + dampening that creates forceful air movement overly stress my drivers & shorten their usable lifespan?

    I have beyerdynamic DT250 headphones: 45mm drivers 250Ohms 100mW 97dB
    I sealed off the cup exhaust ports and covered the cups with acoustic foam to maximize isolation
    and tighten up the bass that was dark, overpowering and slow to release. After the changes
    they sounded bright and bass light on a low power amp. However, plugged to the headphone out
    of my Sherwood S-7200 solid state receiver they created a bass impact that moved massive air
    pressure. It almost felt like the cans were hovering over my cheeks. Heavy bass or percussive
    snaps in treble push lots of air. Depending on the sound source this happened with the loudness
    switch engaged and the volume turned as low as 9 O'clock. I really like the sound. Its still
    accurate and detailed with extremely tight normal bass. Its just the extreme low and high
    frequencies that have impact. Its not as balanced and refined as my modified t20v2 orthos, but
    its got a really fun sound with a gigantic soundstage.
    I'm wondering if this fun setup would be short lived though. Am I taking the driver beyond its original
    design capabilities? Will this dampening and amp eventually distort and deteriorate the drivers? If so
    are there any precautions I could take to keep the sound but still care for the drivers? I don't want
    the fun to end.
