You have absolutely no idea what you are talking about, starting with having no idea what I have. The only thing you know is that I own at least one KL-650-THX.
We call that a "straw man"... the topic is *your* claims. You have two at the moment.
1) "While there is nothing wrong with having a bookshelf based HT system, it is not the same, or equally performing as having tower based HT system. "
2) "Revel center is at least 3 steps above the Klipsch THX LCR."
Bonus: "Revels we are comparing are bigger speakers that will reach lower and produce bigger and more dynamic sound for bigger rooms. "
The bonus can be addressed.
- The Revel's are larger.
- The Revels do extend lower, but that's not actually productive because those frequencies should be handed to the sub for reasons including those I've already spoken on.
- There's no such thing as "bigger sound". But if you are referring to volume, the Revel maxes as 114db (based on amp recommendations, they don't actually mention max power load) and the Klipsch maxes at 118/119 (depending on which sensitivity value I accept), which makes it almost 2x as loud, and it does that at half the power consumption.
- "Dynamic sound" is another non-sensical term. Paired with a 20Hz sub, both speaker sets will cover the full range of human hearing (20Hz-20kz), and the Klipsch will do so more accurately (see FR graph from earlier post).
You can't support your (false and/or nonsensical) claims. That's why you want to take your ball and go home. You are free to do so; but let's not pretend it's because I'm ignorant here.
