    Yeah, I think this setup has plenty of ass behind it. Can't wait to watch some good action movies. I havent had a lot of time since getting the new towers, so maybe we can watch one this weekend.

    I can see why you have that amp. You have a lot of speaker to push. That center is huge.

    Luckily they are all efficient, but even with that the towers can drop into 2 ohm realm and the amp is a benefit. I was shocked at how much larger that center was than the previous model.

    All else being equal, a larger speaker will generally be more efficient than a smaller one and thus need less power. What matters is the speaker's sensitivity, not its size. The Klipsch Reference 7II towers he has are rated at 101 dB sensitivity, so 10 watts in would yield 111 dB SPL and 100 watts 121 dB -- from each speaker!

    Are you a 90% movie guy and 10% music? Or what?? I know you love your flicks.

    Yes and no. Higher power normally brings greater current capability along with it, if only because more or more robust output transistors must be used. You need the additional current capability only if the speaker sometimes pulls enough to hit the limit of what a lesser amp could provide, however. This depends on the speaker's average impedance, its lowest impedance, where that impedance troughs lie with respect to frequency, and the spectral distribution of the content being reproduced. If a speaker has a low average impedance (say, 4 ohms) along with a very low impedance (say, 2 ohms or below) in a frequency range where there's a lot of energy in the program, you might have a problem. The average spectral distribution of acoustic music peaks at about 300 Hz; popular music might peak a little lower and have a somewhat flatter distribution with respect to frequency; action movies often have peak demands at very low frequencies, but those typically are handled by powered subwoofers. Finally, dynamic speakers usually have their lowest impedance just above their primary low-frequency resonances, at the bottom of the associated impedance peak's descent -- for a big speaker, probably in the 80- to 150-Hz range. Speaker sensitivity is also a factor, as higher sensitivities reduce peak current demands proportionately. Finally, mainstream speaker manufacturers are usually careful not to make products that will buckle mainstream receivers, which typically are designed around about a 6-ohm load. Long story short, if your speakers are not esoteric in some way and your amp is rated for enough power into 8 ohms to drive them, given their sensitivity, to adequate levels without distortion, the probability of inadequate current capacity being an issue is really low. If the amp clips, it almost always will be voltage clipping, not current clipping.

    After some talks, I moved the subs inside the towers last night. I think the look is actually better. I am hoping to air out the fronts a little more, because I think those large towers were a little too close after listening to a loud movie Wed night. At times things seemed mashed up, so we will see if this fixes it. With my smaller fronts they seemed too spaced when I tried this, but I also didnt have an AVR with XT32 IIRC.

    I am also ordering a Umik-1 from cross spectrum so I can use REW to see the affects of changes before and after Audyssey runs, and can tell what my speaker placement is doing.

    Visually, your new setup is WAY more attractive. It flows much better IMO.

    Thanks guys, I agree it looks better with subs inside.

    It also improved the sound.

    Using CSI as an example for 5.1, the center sounds like it is coming from the screen. When the fronts are playing the same thing, they sound balanced, but when they aren't, you can tell where stuff is coming from. For example, at a police station, sirens were heard outside out of the front right while someone typing on a keyboard was clear as day out of the left.

    When in stereo, if I stand at the MLP, it actually sounds like the sound is coming from the screen, not the left and right fronts. Perfectly balanced. Center sounds are also more segregated from right and left, doesn't sound like it they are tripping over each other. In a jail scene there was some loud discussion in the center, and some jail doors opening and shutting in the left. Could be easily distinguished, while nothing going on in front right.

    how far away from the wall are your R /L frts towers, if your can get them out about 18" you'll get better definition.

    They are toed in. One corner is 16" and the other is 20"

    The whole thing sounds a LOT better now.

    Watched American Sniper last night, which contains a great audio track. The channel separation and clarity of these speakers is amazing. Now that everything is placed properly and calibrated, I could not be more happy with the SQ.

    The larger compression drivers in the 7II and 64II make an obvious difference, and the 64II is one meaty center. It handles everything in loud action scense with clean sound.
