no-dsp speaker upgrade ?

[btrvalik]

Got my X5 yesterday and the system does not sound too bad on most music. i find that I have to adjust the bass down a bit and keep the treble near flat with a front fade. I'm using the rear just for a little fill so it does not confuse the image too much. I find it actually images fairly well for a car. I definitely need a sub since turning down the bass is the only way to make the stock speaker sound o.k. I would then be interested in finding a mid bass upgrade for the fronts. El duderino I've seen you recommend the DSL UP6 elsewhere, will the tweeter fit in the sail pods? Is the mid-bass available separately? If not could you recommend another mid-bass driver. I think the factory mids & tweeters work fairly well together.
