I think the DRZ9255 is the best solution out there. Granted it only has a 10 band PEQ instead of a 30 band GEQ but you can do quite a bit with 10 bands. Compared with the high end choices from Alpine, Pioneer, and Nak the Clarion has the most realistic and deepest sound stage. I'm considering this URAL unit but my heart still lies with Clarion.
got_wake, so you mounted your domes in kicks and weren't satisfied with them? I'm tossing between placing them in kicks or placing them just above the drivers in the door...but w/o time alignment I'm afraid puting them in the doors will make them too near-side biased. Any thoughts?
DLS has several dome midranges and there are a handfull of other companies that make them too. Think of the domes like mid-tweeters instead of mid-woofers. 4" speakers don't really compliment 6.5" speakers because the 6.5" can play everything in the 4" range in addition to the lower midbass. The domes however do a better job playing the higher range where a 6.5" or 4" driver starts to get harsh but a standard tweeter still cannot produce. The only usefulness I see to a 3-way set with a 4" is to find better placement for the mids (for example, you want kickpanels but can't fit a 6.5" driver there) but now that domes are more affordable...I'll prolly never go back.
