@yyzsantabarbara You should be able to acquire an OB for the price of a used Coda 16. I paid $3k for these with a 15” woofer and sub designed specifically for OB’s. And they were made with zero MDF. They’re solid Sapale, commonly used as a Rosewood replacement for guitars.
The huge benefit in OB’s is the capability of using flea watt tube amplification to drive them. You can’t do that with a typical box speaker. You need power, and typically lots of it to drive them. You need none of that to drive OB’s
