It's not about missing frequency,  it's about actual output.

I'm not a fan of speakercraft amps but at least their 35WPC amps have some sort of output.  These things sound more like about 6 watts.

My Boston 3 1/2" alarm clock from 10 years ago has more output, seriously

Most of our zones hover around 25 - 35% volume for "comfortable" listening levels with plenty of headroom to rock.  This zone had to be at 100% to even get comfortable volume.
