dpj1Price does not always correlate with sound quality. As with most 12v car electronics there is a production lifecycle so when a company no longer makes the product the prices are driven down by resellers. In this case the speakers on offer are not part of Pioneer's current lineup.
You could look up reviews on the individual speakers offered in this set for a better idea of what to expect.
