That’s a bit of a misinformed statement. I know everybody wants to call them “cheap” speakers. The fact is that they are designed to different requirements than aftermarket speakers. The are three important design criteria. First, weight, neodymium is not cheap. The cones, contrary to everyone’s belief, are not paper. They are a proprietary fiber. It is lightweight and rigid. Second, ease of assembly on the vehicle assembly line. Custom speaker baskets for different cars are not cheap, when you have to make tooling for each basket. Especially for a car like the Camaro when they were only building 20k/year. Those molding tools can cost upwards of $250k, and we’d need 4. Third, high reliability. Aftermarket, doesn’t have to, nor do they design to meet validation OEM requirements. Each part number costs over $1M to run through validation for quality.
Now for EQ, no speaker has a response curve. Neither does the environment that the speakers is placed in. The point of the EQ is give desirable response from the sum of the two, but also taking into account phase and delay.
I don’t know what people are using for source material, but it makes a difference. If you listen to XM, FM or Bluetooth you’re never going to be happy. It’s too compressed and bandwidth limited. Get out the USB cable, enable the loudness curve on your iPhone or android, and you’ll hear the difference.
BTW, the EQ is done in the amplifier.
