Are there any speakers for 2020 Prius thst go 20 hz to 20 kHz? I won’t buy new speakers that all seem to show crappy freq range like 60-18 kHz or so. And subs even show 45 hz or even worse. I’d prefer door speakers at 20-20 or at least not so crappy like 45-60 hz. For a sub I’d want one 10 inch ported 20 hz. Not crazy power tho im not into that. Just normal Electronic.
It wouldn't surprise me if the drivers listed with "crappy freq range" were just advertised more honestly than some more "impressive" ones. Maybe it's easier to get good reproduction in a car cabin by using what drivers are available and setting EQ empirically?
Eq takes away from the intent. I do t change it. It’s always set 0. I find it pathetic if a so called sub goes to only 45 hz. That’s not sub. Sub is sub bass. Low. 45 ain’t that. And for door speakers to only do 60 hz is pathetic too.
Depends on whether you think 'intent' is about what you're hearing in the space where you're listening, or just arbitrarily what some driver might produce in lab conditions.
Maybe listen to online tone generators. One example: Online Tone Generator - Free, Simple and Easy to Use My perceptual limits is around 50~7900 Hertz But I'm in my 70's; I think the high-end in particular goes as you age. addendum: some revision to top end, in red. Just barely discernible
Sine: (baseline) Square: similar, somehow "cleaner"? Sawtooth: significantly muted Triangle: slightly muted Turning each on/off helps, to differentiate from ambient noise, tinnitus, imagination.
Mathematically, a square wave is a sine wave at the fundamental frequency (here, 7500 Hz) combined with sine waves at all odd multiples (3 ✕ 7500 = 22500 Hz, 5 ✕ 7500 = 37500 Hz, and so on), with each n✕frequency sine wave having 1/n the amplitude. A triangle wave has the same components, but dropping off faster (each n✕frequency sine wave having 1/n² the amplitude). The sawtooth is composed of all the integer multiples (not just the odd ones), dropping off at the same 1/n rate as a square wave. Those are infinite series which, as you can see, quickly exceed the frequency limits of the equipment reproducing them (which is why nothing will ever produce a perfectly-square or perfectly-triangular or perfectly-sawtooth wave). Starting with 7500 Hz as the fundamental kind of means your equipment's limits are already exceeded at the 22500 Hz frequency✕3 component (the second extra component of the sawtooth wave, and the first of the square or triangle). I suppose you're hearing the triangle muted and the sawtooth even more muted, because you're not really hearing the higher-frequency components, but only that the fundamental has become less of the total loudness. It might be interesting to seek for the highest frequency where you can clearly hear different tone qualities in the different waveforms. With a 4000 Hz fundamental, for example, the equipment can probably reproduce the 3✕ and (just barely) 5✕ in the square and triangle, and the 2✕, 3✕, 4✕, and 5✕ in the sawtooth. It might be that you do perceive some of those higher frequencies as making tone-quality differences, even if you're not conscious of hearing them directly. (Or maybe not. I'm not an audiologist, and an audiologist would probably know.)
Depends too: pc with ear plugs, vs iphone, vs surround sound system. I should try on the latter. Again, turning the sound off/on helps, and turning your head, shifting al little.
