i got a 2012 escape limited. it says it has 7 speaker but only see 5. going to replace the sub with a 8" Comp C84. if it doesnt improve any thing it wont be a big lost got it for $30. ill replace the speaker in the next 2 months with some kicker DS68 ic an get the front and back pairs for about $60. so if for less than $100 total i can get better sound with out any visible modification it will be worth it. post in about a week the results of the new sub.
The 7 speakers are:
2 in each front door (separate midrange and tweeter in a 6x8 package)
1 in each back door (full-range OEM paper speaker)
1 sub in the trunk
They stopped putting the tweeters in the sail panels in 2008 I believe. Unfortunate, since that location provides much better directionality to the sound. AFAIK no one makes a sail panel for the 2008-2012 Escapes that has mounting provisions for a tweeter.
