Why don't these sound any better?

Idk, pulp cone, plastic basket, tiny magnet. Those have audiophile written all over them.

Who removed the magnet?

Classic OEM. coupled with the bass-filtering in oem headunits once you turn them up they really bring out the worst is already bad FM quality.

And that’s why the first upgrade that I did to my Mazda was to buy an expensive set of Polks. Money well spent, even with the stock head unit.

It’s an upgrade.

Yeah, those are the sports models - you know, lightweight for better handling...

The magnet is smaller than tiny.

nobody. they’re neodymium (NdFeB) magnets, which are 10-15x more powerful than the typical ferrite magnets so they only have to be a fraction of the size. instead of a big ferrite ring encircling the voice coil between the top plate and pole piece, the magnet is a disc which sits on the inside of the coil.

if that speaker sounds like crap, it’s not because of the magnet.

everything you just said makes me angry.

I bought an inexpensive set of Pioneers for my Mazda. Stock head unit.

Oh, I know. I was just harking back to the old school speakers I was used to from the ‘70s and ’80s , especially the ones on the speakers hanging from the ceiling in the dumpy, ancient electronics store I worked at in the early ‘80s; the place was so old we still had signs in the window saying that we accepted BankAmeric ard and MasterCharge.

Big-ass magnets ‘cause that meant they could take more power, even if it meant no cargo space and lots of erased cassettes when you cleaned the car for date night. And nowadays we’re lucky if we can find an unmolested package tray for an ‘80s hot hatch thanks to that  ’bigger is better’ mentality, and yes, my Rabbit GTI didn’t escape this molestation.

the funny thing is, the size of the magnet doesn’t appreciably affect power handling. what mostly determines it is the size/wire gauge of the voice coil and the material the voice coil bobbin is made from.  a 6.5" or a 5x7" speaker with a 25mm voice coil can only realistically dissipate about 30 watts max regardless of how big the magnet is.  there’s no contact between the coil and the magnet, so any heat transfer is mostly radiation with a bit of convection.

I’ve worked in both OE and aftermarket car audio. those, uh, things you buy off the display wall at Car Tunes or Best Buy aren’t all that great either.

and besides, any door speaker of any size (6.5", 5x7", 6x9") needs a high pass filter (the “bass filtering” you deride.) They are physically incapable of producing the lower octaves of sound without also producing a ton of distortion. I’ve evaluated a depressing number of $2-300 aftermarket component speakers (claiming a “60 watt RMS!” power rating) which produced the most disgusting amounts of THD and modulation distortion in the bass, and that at only head unit power (16 watts continuous.)

there is a ton of garbage out there in aftermarket car audio.  they put shiny, sparkly cones, cast baskets, and rubber boots on the magnet to make you think the speakers you’re buying aren’t pieces of shit.  but they are.

guessing that’s from a Mazda?  I can tell by the date code that Foster is the speaker manufacturer.

Sure, but we sold lots of expensive  bulk Pyle (and other second and third tier brands) speakers with massive magnets to those with, umm, inferiority issues that wouldn't listen to discussions about what makes a speaker sound good or work efficiently. Who were we to refuse their money?

Showoff. But to your question, yes: 2011 Mazda 3. Such unmitigated crap. In my experience, a couple of $50 pairs of speakers can make a monumental difference with a stock head unit. I’m not interested in trying to switch the head unit because aux jack present.

the 1970's called and want their speakers back....

they weren’t using neodymium in the 1970s.

I’m aware of the subsonic filtering is needed, but not at bloody 100hz and down. Yeah the cheap aftermarket is really no better, you need to go a few price ranges up before it becomes worth the upgrade...

On a side note, i had the magnet go loose and start slipping sideways on a Hertz HX subwoofer, but luckily there was protrusions to the side of the magnet, so i threw a bunch of plastic shims in around it and glued as best as i could to keep it there...

I believe the speakers were substantially crappier then. Like tissue paper.
