Ok, first off i was kinda in your same position, looking at about the same speaker lines, i decided to save up a tad bit more money and go up a line. I am very happy with my decision of doing so! After about umm 2 months or searching and picking my own brain and all the other well if i go with this and that, i decided on going with rainbow. I knew they made very good speakers and most of there money they get goes into R&D. This was a big plus, so i took the plunge and went with the soundlines, a step above the dream line. When i first installed them, i loved the tweets. very crisp and detailed but yet not tingy and harsh like a metal tweet(there silk btw). the midbass on the other hand seemed flat and lacking. after adjusting my eq's a little bit it woke em up a tad bit but for some reason not enough. But i figured i had to let them break in. So i did. after about a few days, not constant listening, they started waking up! Seemed like they were a new speaker. I have 150 watts rms runnin to them and they handle it like champs! I am, very very satisfied with rainbow, as they would easily compete with high high end home audio( i work in audio store in the winter, and i know hard comparision but if you break down the basics of it, you can kind of understand). would i keep the speakers forever? Possible, but probably not, i wanna try some DLS, so these babies will be out pretty soon lol. Rainbow and DLS have my vote ! Hope this kind of helps.....you guys think this should go in the review section? lol kinda long...
