I just received the Music Direct mailer, where they showcase such a speaker. I don’t remember the details because I had to swat a fly and the mailer went in the trash. In ancient times I put together a five driver per side speakers with some exotic British “full range” long throw metal drivers that were about 21/2” in diameter. I used a high order active crossover to subs. Very efficient and driven by 10 watt per channel SE 300b amps. Everything was analog in those days and the musicality and imaging was really nice on a budget. Think of bobbing up and down on the ocean while rapidly splashing. The short wavelength simply ride on, or modulate the longer wavelengths. Like all designs there are obvious pitfalls to this approach. I’ll have to take a look at that MD speaker online.
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.
