I am ****ing satiated. These speakers do everything I want and more. They can utterly drown my ported CVR 10. They appear to be more efficient than my germaniums judging from volume produced vs. light dimming amount. I got the dynamat on the doors today, but didn't have quite enough to cover every square inch of the interior metal...i did, however, get all the holes sealed up with it - and it was more than worth it. I don't think i could ever find any reason to replace these speakers. I'm floored. These produce excessive volume all the way down to 50hz while still producing exceedingly clear sound in the midbass and midrange frequencies, and i am totally in love with the cal-27 tweets - excessively smooth and detailed, even less harsh than the cal-25's and yet able to get considerably louder without any perceived harshness all the way up until it just hurts because it's so freakin loud. You can tell it's clear if you stand outside the car and listen but inside it's painful. Next up, i've got to get the door panels deadened a bit and get those put back on after cutting holes for the rainbows to poke out of as they extrude way too far off the door to fit inside the stock door panels. Pics of the ghetto partial dynamat install tommorrow. It's pretty amazing what a difference only ~10 square foot per door makes.
