Well I don't think that's a valid conclusion since HK was always low on the watts-per-dollar derby anyway-I don't think we can take them as a cost proxy for the regulated approach.
- When I worked for a giant autosound company, unregulated got you bigger numbers, albeit in a different technical scenario.
- And all that is when tested into RESISTORS. Into real speakers, I suspect a non-drooping design would do better than the poorly regulated into real speakers under dynamic conditions. Tricky to test and prove or disprove, however, and impossible to cost out unless you're actually working on such projects. Hmm, my old business partner talks to a lot of factories, I'll have to ask him...
