The TSi Series is probably one of the best front tower speakers. The mids and highs were crystal clear without too much overpower. The bass is rich and somewhat deep. They handled the vocal music quite well with the soothing voice of the singer. In my opinion, one of the best way to test speakers is how it handles vocals accompanied by only one or two musical instruments like guitar or keyboards. I've auditioned other speaker brands and when playing fast beat booming disco music they were okay. But when they played slow, jazzy vocals, it did not sound good.
Got a chance to audition this at MLY Enterprises ( AVShop ) and we played various music types, Slow, Pop, Jazz, Upbeat and they all sounded great. The audition room at AVShop was kind of spacious and ideal to test out music and movies. Bass is semi-soft and punchy and the highs are clear.
