@erik_squires in the case of commercial active speakers for the residential market how would you calculate the portion of the markup you are highlighting that is attributable to the work of matching the amplification to the speaker? For many responding to your original question, they value the flexibility to do that work themselves (i.e., matching external electronics, and in some cases DSP, to passive speakers), but objectively, that work has value (or cost, even if it is *fun* for them).
Isn’t the seller of actives in part offering a service of doing that work for the buyer, who, like @fastfreight ’s son, values *not* doing that?
Put another way, assuming you were willing to do it, how much would you charge over the cost of the components to build a 2 channel pair of actives for a stranger (i.e., someone for whom you were not inclined to do favors)? And can you break out the pure labor time for assembly once the pieces are chosen from the time necessary to choose the right pieces for the best synergy? (And I suppose there is also the additional time needed to design the enclosures to account for the vibration issues others have mentioned?)
