I knew it shouldn't sound boomy or inarticulate but my experience with decent 1x15 cabs is limited so I still surprised myself with the clarity it's got. As you say it is very nearly a Gen 1 Compact, or probably closer to the lovechild of a Compact and a Greenboy Bassic so all signs pointed to it sounding good.
Wasn't a huge amount of money, though the CNC cutting wasn't cheap. If it wasn't for the fact I got the speaker itself cheap then this would have cost nearly as much as a 'shop bought' cab. Of course, money saving was never the objective 😂
