You're right. Each speaker has an ideal/optimum cubic dimension. The manufacturer may actually give you that dimension if you call them.
I frequently create .75 cubic foot enclosures for speakers with 5.25 inch drivers. You might just go with that... we go to .8 cu feet for slightly larger speakers, and go to 1.2 cu feet for inwall subs (two 8" drivers). This is for some Bay Audio speakers, and I call tech support any time I install a new speaker model.
You might try tech support for your speaker, or just try one of the above dimensions. Use dense and heavy material, seal the enclosures, and insulate.
