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.


@ronboco Yes, I am very much a budget-conscious consumer. I watch a lot of reviews and GR Research stood out to me. There was something appalling about seeing cheap crossover parts, drivers and flimsy cabinets on major brand speakers, some of which costed thousands. I was still rocking the Klipsch RP600M which I loathed since day 1 (They suck). So yeah, I figured that I’d look into single driver speakers with sturdy cabinets and no crossover to muck things up. At least most of the money will go into the drivers and the cabinet. 

I visited a shop in Paris which sells a bunch of single driver speakers (unbranded DIY kits) alongside Atohm and Davis Acoustics speakers. The speakers based on the Audax AM21 driver were brilliant. I gotta say that the Atohm and Davis Acoustics speakers sounded veiled next to the Audax AM21 which were just faster and more immersive. I didn’t get the AM21 since they were a bit too large for my tiny living room. 

Years later I experienced a few other speakers with multiple drivers and they were just great. I could happily live with the KEF LS60 but the price is eye-watering and they exhibit an overly “clean Hi-Fi” sound at times. At the very high end you get to have a larger sense of scale/depth/volume and way better bass. But I personally don’t feel like my single driver speakers are bested in the midrange/treble/detail categories. 

You could assume that my hearing isn’t great, and that wouldn’t be far fetched. So my end game setup is very attainable. I’d like to be the village idiot in that conversation, or the average person at the very least.

My ears say otherwise, but they can’t read.

@dlcockrum You might want to go some place where you can hear other speakers. As I pointed out earlier, it makes a big difference what sort of music you play. Any ’full range’ speaker will fall flat on its face playing a lot of the music I like to play, even if not played all that loudly. This track has a fair amount of bass in the opening section:

Your speakers won’t even acknowledge that the bass notes are there. But those bass notes will cause the speaker to make distortion and sound congested. This track isn’t congested.

FWIW the speakers I’m playing are the Classic Audio Loudspeakers model T3.3, which is a bass reflex speaker flat to 20Hz employing 15" field coil woofers and field coil horns. I play bass and did so in a variety of orchestras so I expect the bass to be right otherwise I’m not convinced.

At any rate if you don’t play tracks with bass or simply don’t like bass, you might consider a filter in your system to block bass from getting to your amps and speakers- you may find they sound better as a result.
