New Speaker project sounding terrible?

Here are some problems most experience when learning how how to build speakers, these are some of the questions that come my way.
Speakers are not as loud as I wanted
Speakers have bass but sound a little thin, I hear the bass but it's really not as good as I hoped
Highs are not as crispy, it has good frequency extension but Idk sounds like it could be better.

With the Bass tracks/samples i actually said nah im not gonna guess as usually a guess is a mess...But funny enough i instantly heard that the second sample playing had "More" Bass so it made sense that the first one post swap was it was one that had the higher roll off i.e 50hz lol sometimes we get pleasantly surprised but i would not have been accurate on the other samples, this is why i elude to many people that our ears plays tricks on us often with sound. On with the rest of the video.
