EVERY speaker design has to compromise somewhere, and this is certainly no exception. In forgoing multiple drivers and crossovers the single driver will have limitations/distortions — it’s just physics. But, any skillful designer can effectively minimize the compromises while maximizing the benefits of the design. Such is the art of speaker design.
Perplexed on how single driver speakers can cover such a large Hz range
I googled till I was blue in the face. I've always wondered how in the world the cone of a single driver speaker, with no crossovers, at any given ten thousands of a second, be vibrating a hefy 60Hz and also a sizzling 10 kHz. To me it's like quantum mechanics. I don't understand. I just have to accept.
