The Pioneer TS-G1323i 13cm 3-way car speakers (89dB, 220 watts), but about 10 more expensive than the other two, had the best sound. The bass was the best / most powerful and well-balanced sound and clear.
The 2-way model Pioneer TS-G1321i 13cm sounded unbalanced (since only 2-way), the bass was like the big brother but also good.
The Sony XSF1337SE 3-way car speakers (13 cm, 160 Watt / 40 Watt, 86 dB) were also good, clean sound (the 3-way Pioneer but were somehow clear / balanced) -the bass but was still weaker than of the 3-way Pioneer (the membrane also did not move as much as at Pioneer).
Why did I keep the 3-way Pioneer TS-G1323i 13cm - which look a lot better if you have to use the plastic casing.
