I would think that the radio should have decent bass if it has a good sized speaker. Even an 8” speaker should sound good. Having the speaker in the cabinet the way you have is the best way to judge audio quality.
If you have replaced the caps, recheck C16 and C22. Recently I was working on a radio, and the cap on the volume control wiper was bad. It was already replaced with a .02 yellow cap. New mass produced caps can be bad. I had the same issue you have, poor bass. Sometimes C27 the 250pf mica cap goes bad, but that would not likely cause low bass.
A quick swap of the 6Q7 and 6F6 tubes is not a bad idea if not already done.
Hope this helps.
