And the tweeters in the rear side panels too. The underseat speakers are woofersr but the difference between a sub and a woofer is moot. Generally the big speaker tuned to do the lowest frequencies can be labelled a sub woofer the larger door speakers are mids and then the tweeters for the highs in the doors. So I shall carry on calling them subs as that's what they do. They are all woofers!
