Question Frequency attenuation?

Is it possible to attenuate everything above a certain frequency? If it is, are there any sonic drawbacks?

I have a driver in a sealed box with an F3=80~, but would like the speaker to be flat to about 60hz. So, could I attenuate everything about 60hz to achieve this goal? I realize I would lose some efficency, but I can deal with 90db 1w/1m.

This is a two-way, so both the woofer and tweeter would need attenuation.

You don't need to attentuate, you need to EQ/boost the low end to bring your curve up.

Of course you could start by designing the box to meet your goals.
I was so much older then, I'm younger than that now.
