Welcome!
Loudspeaker building is full of hazards. Not being able to audition before hand is one. Another is proud papa syndrome. Focusing on lumber, veneer, and woodworking versus sound quality is a third. Discounting the skill/experience of loudspeaker designers/builders is a fourth. Ignoring the advantages of active design is a huge fifth.
Example: for $300/pair you can buy Kali LP-6 2-way front ported active very capable/serious monitors with wave guide that sound smooth, detailed, and with excellent imaging. They have built-in amplifiers so your whole system could consist of a preamp/DAC, patch cord, and loudspeakers.
