Hertz CK 165 16.5cm 2-way component speaker, 95W, 4Ohm, 55Hz - 22.5kHz ~ Cento series ~

I've had these speakers for about a week now. These are in every way superior to stock speakers. I fitted these in my Honda Civic with no problem. At first, you wouldn't notice much improvement over stock speakers (my ears were blind at first). However as you get used to listening to these speakers, you slowly start to notice things you didn't notice before. The percussion from the tweeters are extremely clear, its as if someone was playing in my face. The instrument separation is also top tier, I could hear each instrument individually which I couldn't before. It's so immersive even with just the front two speakers installed. I am looking forward to getting the coaxials for my rear speakers in the near future. The only minor drawbacks is that they are heavy drivers, though this feels very high quality. And the bass is not as good as stock (which is to be expected as these are mid range woofers), although once again you can feel the instruments including the kicks, which I couldn't before. Very minor drawbacks, and more than impressed with the major increase in sound quality.
