Question for BSW re: speaker replace type

[Kewl X5]

Okay, saw the BSW website re: speaker replacements for the BMWs....

The lowest priced ones are sold out....however, the MB Quarts and Rainbows are still available.....

E46 M3 Coupe with HK....want to replace the front speakers....already have JL Audio Steathbox for subs which fits in the rear mid-bass speaker area and rewired the 6x9s to be the mid-bass drivers and the rear tweeter, front tweeters, front mid-drivers, and front mid-bass are still stock. I am not thinking of adding an amp for the regular speakers (already have a 2-channel JL Audio amp powering the rear subs).

So basically, want to replaced the front mid-bass, mids, tweeters and probably the rear tweeter (the JL Audio's steaths are fine for my taste). I didn't want to looks any more trunk space.

Listen to rock, dance, some hip-hop, and occassional classical.

So MB Quart vs. Rainbow? Pros and Cons....Heard that MB Quart's tweeters are a little "bright" sounding and the Rainbow's are more "natural sounding"....However, the speaker material on the MB Quarts appear to be higher quality. Not going to add another amp for the front/rear speakers (keeping stock headunit and OEM amp).

Thanks in advance for any opinions.
