The hopes of a flat set-up in the back was what made me go in with my checkbook and trying to keep an open mind on the 3-row. That's the thing I really missed from my old 4Runner moving to the 80-series, as the way the LC (and Prado) seats seem to want to fold nowadays makes it impossible for me to stretch out when camping. But seeing that interior vertical room in the back of the 3-row OT was just really bad, and the actual measurements showed it's just not tall enough for what I need to carry.
I was rushed so didn't spend as much time as I meant to looking at the Mark Levinson sound system on the LX700h OT, so I'm trying to reserve final judgement until I get to try again with a 2-row. Or hopefully when more people get their hands on these they'll chime in with info. But what I heard in my quick test has me very worried about the ML on the LX700h, at least in the Overtrail. Based on the shortcomings of the GX ML, I tested by fading the system all the way to the back, and it still appeared that on the LX they also didn't bother to put any full-range speakers anywhere but in the very front. Sounded worse than a cellphone in the entire back rows. On the GX even with a normal placement of the fader results in terrible sound in the back, even more embarrassing if you have the rear hatch open. By comparison my LS sounds just as good for the rear passengers as the front, with a complete set of full-range speakers in all the way in the back.
While they cheaped out on the GX, I can't believe that the LX would be left with this problem for passengers, at least on the Luxury and Ultra, so I'm hoping I'm just wrong here and it's some issue with settings I didn't get to. Enough people have their hands on the GX that there are plenty of thread comments trashing the GX ML, and were already even by the time I got mine and heard the disappointment. But just doesn't seem to be a lot of info on the LX out there.
For my tastes it's not about whether the sound is deafening in a quiet car, but whether it can sound good, even at low levels. That's harder to do than just adding watts or sub woofers, but Lexus used to know how to do this. I'm guessing they now assume that everyone is listening to heavily compressed audio via streaming, and they can get away with releasing garbage. At least for the GX, that seems to be the case, and hoping I'm wrong about the LX.
