I've admittedly not auditioned any Bose speakers. But whenever the subject of Bose comes up on any audiophile forum I visit, the responses are hilarious:
Bose draws the sneers for a combination of these reasons:
1. Bose spends more advertising its speakers than ALL other speaker manufacturers combined.
2. Bose pays a commission to store salesmen over and above what the store itself pays! Salesmen therefore have an extra incentive to push Bose.
3. Shoddy component parts. Dismantle a Bose speaker and it's filled with cheap off the shelf parts.
4. Bose top end speakers are designed to fill the room with sound - by bouncing the sound waves all over the room! This plays hell with resolution/detail, and it's detail that audiophiles most value!
