Summary: I bought these to replace my factory speakers and they sound awesome. You can hear every single bit of the song. Be ready to change the EQ to make sure whichever songs you want to play sound correct. What else can I say? They are great all around speakers to play a variety of songs.
Summary: I recently bought Sony XS-GTX1640 speakers I am very impressed by the clarity of the speakers they have a decent low and an amazing high end. I would recommend these speakers if your looking for a inexpensive way to give your system a good sound for a low price.
Summary: It is difficult to write a review on an item when it is only tested on one stereo car system. I have a stock Delco system in my car and I installed a pair of Sony's XS-GTX1640 Coaxial Car Speakers. I got a very good variation of sounds. Deep lows and piercing highs. Pending on what you're listening to. CD's need to be EQ'd to get the write sound to your taste. Listening to FM radio has a great body of sound. I played Metal, hard rock, classical, pop, jazz and hip hop.
