I am in the same boat except choosing between Morel Elate 6.2 and Seas Reference 6.2. I just ordered Seas Lotus Reference and will run them active with Audison LRx 4.5 (4x70W RMS), hope to get them installed by next week. Interesting that you are installing coaxial at the rear as I am leaving them empty. As for HU, I have decided to go with Clarion 956MC rather than Pioneer P880RS because of Clarion's Music Catcher CD Recorder and 24-Bit D/A Converter, but I have to admit the P880RS looks really cool.
