Monitor Audio CP380 idc

Recently I got those 4 speakers for Atmos duty upgrading from smaller sibling c265idc.
Previous speakers I used a small 12” x 12” box and they were crossed at 80Hz. Now I’m discovering, despite bigger 8” vs 6” driver they only extend to 107Hz due to smaller enclosure.
Two questions
- is it big deal for Atmos ? Will I enjoy bigger speaker regardless of its lesser output under 100Hz?

Edit:
Got them room corrected and seems Dirac was able to push them to 55Hz@-6dB which probably- how bizarre

- can I drill some holes / vents to improve frequency response or that would be bad idea?

one of the worst ideas I've read on here, no offense

It's not just the holes that give speakers better bass extension, it's those coupled with the right woofers and precisely designed tubes going into the cabinet.

Just drilling holes into a sealed speaker will simply ruin it.

A quick google search shows that these are 3-way in-ceiling speakers which means that they are designed for an infinite sized enclosure (aka infinite baffle) as opposed to a small box. The obvious solution is to cut a hole in ceiling and use them as designed.
