Step 1: Do not buy the Bose.
Step 2: Read through the speaker forum and the pro reviews to gather advice and information.

Step 5: Once you have gathered enough information, opinion and first hand experience through auditions, then buy speakers that will keep you happy for many years. To ensure your long term satisfaction, refer to step 1.
