BSW stage 1 people please help regarding rear door speakers
 

Are there tweeters in the rear of the x5 or just midrange, looking at the door pannel? According to the BSW manual, there are only midbass and mid range (which makes perfect sense for imaging, but since when does the factory get any thing correct reguarding audio).

So if i am correct, the front is a 3 way system, tweeters, midrange 2.5 and mid bass 5.25, rear is 2-way no tweeter

correct.

so the only way to upgrade our speakers are to go with the BSW kits, in order to keep the imaging and 3 way front system.

i haven't seen another kit and i've looked just so i would know my options.

check a local audio dealer/installer in your area for ideas maybe?
