Feature

Middle of the Pack
The TSi400 approaches the performance of the TSi500 but improves upon TSi300's. If you don't need the extra bass response or power handling, the TSi400 is the speaker for you. With three 5¼" drivers and 1" silk dome tweeter, the results are higher power handling and extended bass capability over the TSi300. TSi400 is incredible for high impact movies and music.
