Sufficient bass and treble is delivered from my set. Me too not the kind of person who keeps the sound so loud that the others on the road enjoy my music too (I am selfish :up ). For the 1st 2 days after installation I used to keep the volume at 20 for some songs, later settled down to 12, now I am hovering around 6 to 8. No rattles/distortion for all these ranges. I had a set of oval Pioneers in my previous car which did a good job, but that was along with a sub, so I am not sure if without sub it meets your needs. Based on the research done by me Polk, Hertz and few others are top end competitors while Sony, Pioneer, etc are entry level competitors. So there is definitely going to be a difference between a lower top end and a higher low end speakers. Sony definitely is not good because I have heard Sony ovals in 2 of my friends car and was absolutely flat. There were no way I could audition all these and just went by the reviews available online. At the end of the day auditioning is the only way you can find the right speakers for your ears. I have bought these with bill and 1 year replacement warranty. Installation is free everywhere.
