I have started a new DIY project with a lot of help from my friend Jon Hancock. This is the new project diary I will use to document the progress. There aren't many DIYers here, but maybe I can change that. ;)
The new project is a full range 2-way design using a Seas tweeter and the Adire Audio Extremis midwoofer.
The Seas 27TDFC tweeter is a great performer for this application and is popular in high end audio designs. They are used by Joseph Audio and Reference 3A to name a couple.

The Extremis6.8 is a high tech midwoofer. It uses a dual gap motor (XBL^2)with a copper shielded pole piece. It has massive excusion and low distortion down low compared to the Scan Speak 8545. Here is the Xmax video:
