OK... differences... 1) bi-amplification and active crossovers and equalization. 2) tweaked sonics and loudness contour 3) authentication 4) 5V "USB" charging 5) improved TDMA immunity (some brilliant engineers thought it would be a good idea to modulate digital cell phones in the middle of the audio band - actually it improves range and battery life - and most importantly increases bandwidth for the cell phone company - but it stinks for audio circuits) The first two might be self-explanitory

1009098 is for the 120V model of the SXT "WWi" version. 1009099 is for the 230V model. "MFi" models are 1010315/1010316 for 120V/230V models. The 120V and 230V models are identical except for the power cord that comes in the box.

[quote user="Professor Thump"]Well I took the plunge yesterday a noon and picked it up. Got into a little discussion about the coming revolution with the salesman in the store. His comments were that it was coming sooner than later. I think he just wanted to sell more guns. You don't need to comment on this to keep the thread open but you can PM me for an opinion. Shot it last night at the range. It shoots right where I point it. Much more accurate than my XD9. Once or twice the gun

Every time I shoot a Sig (225,226,229) the bullets go right where I point it. Most of them have good triggers, I just don't like the placement of the slide lock; I just can't seem to push it up with my thumb knuckle. But at least the decocker/safety is isn't way up on the slide like the Walther and Beretta. As for the Kimber, you were probably smart by putting it back down. In that price range I would go with a Springfield 1911.

As mentioned by Mark there could be more than one thing going on, and since I don't know what test method is used by the receiver, I can't say exactly what the problem might by. There is phase and then there is polarity. Phase can be anywhere from zero to 360 degrees (technically it could be more, e.g. delay, but in the steady state, meaning a continuous sine tone, we just talk about phase from zer to 360 degrees). Polarity is either zero (in phase) or 180 (out of phase). All of the speakers

[quote user="Professor Thump"] If the image is center then the polarity is In Polarity. If the image is skewed and to the sides of the room (phantom image) the polarity is Out Of Polarity or Reversed Polarity. [/quote] This is a good point.

Here's a visualization of 1/2, 1/4, 1/8th space. http://www.trueaudio.com/st_spcs1.htm full space = 4pi steradians half space = 2pi quarter space = pi eighth space = pi/2 For each additional halving of the space from full space to eighth space the SPL increases the 6dB (theoretical). In the real world you never quite get 6dB because the boudaries are never perfectly rigid (some energy is lost by sound going into and through the boundary) and due to the fact that a subwoofer is not a point source
