Monitor series 1 vs series 2

Good day, back in the day I had a pair on monitor 70 series 1 but lost them in the divorce. In 2011 I bought a pair of monitor 70 series 2 on clearance. I loved the silver fronts of the series 1 and spent the last 9 years searching Kijiji (Canada’s Craigslist) and yesterday I finally found a set in mint so I bought them. Once hooked up I immediately noticed quite a difference in sound clarity. They were much clearer sounding than my series 2. The one difference I noticed is even though I have them amped at 330 wpc the series 2 at moderate listening level, the woofers barely vibrated, whereas the series 1 at the same volume had some excursion to them. Could this be account for the clearer sound? I also have a pair of monitor 40 series 2 hooked up to the avr along with a pair of rtia1 and a csia6 center. At moderate listening level the monitor 40’s barely vibrate while the rtia1’s and the csia6 have a decent amount of excursion to them. The monitor 40’s sound pretty good but Is the lack of excursion causing them to not sound the clearest they could be like the monitor 70’s? Has anyone else noticed this with their monitor series 2, that you have to have it cranked to ear hurting levels to get any excursion out of the woofers?
