Purchased were the Pioneer speakers to replace the original speaker of a Renault Twingo. In 2001, as in these the beads (foam) are torn with age. The price-performance ratio is certainly in order, but I was hoping for more than just standard speaker based on the reviews and the description on the Pioneer website. Volume increase despite 40W RMS at 89dB / W / m impossible (oversteer at half volume at a JVC car audio system with 22W RMS per channel according to the manufacturer). Maybe it's even on the radio. For the price of the EIA of 79, - I was disappointed.
