Yeah, maybe Onkyo will decide to include independant sub EQ with XT32 on the 819 model, very misleading on the 818, doesn't really matter to me, I could care less if it had XT102:)
That right there is the biggest factor in me not getting myself a new Onkyo for Christmas. The only reason that I want a new receiver is to get XT32 and EQ my two subs. At $680, it's a LOT cheaper than the Denon 4520...but I can wait. :)

I hear that Brother, was all set to order the 818 when Archaea over at AVS put his up for sale the first day he bought it for $700 delivered rather than go through the hassle of sending it back, he found out the hard way of no dual sub EQ, I was really thankful I read his classified, plus the 32 was no improvement over his XT. Kurt almost bought it to when I posted the sale at Newegg, he caught the no sub EQ as well, bad on Onkyo really, why would they leave that out...........:confused: That is the only reason I would even consider XT32

So If I get 2 subs for the 818 only one sub will get the EQ ahblaza? I never tried 2 on my 707, but I guess it did have it. I only had one sub on the 707 when I had it. So maybe I will wait for the 819 then I like options too.

No, it just means you can't EQ them independently.... so each sub will get the same EQ'd signal.

It's essentially like the receiver has a built in y-splitter for the sub cable... and nothing more.

Exactly what Alph said, the same identical signal is output from each .2 sub pre-outs, so essentially you are EQ'ing dual subs as if there was only one. Receivers with sub EQ calibrate each sub independantly, so each .2 pre-out has it's own signal and not combined as Alph said, like a built in Y splitter. I just took for granted that XT32 meant sub EQ (different independant signals), the 818 would be a steal at the $700 street price if it had sub EQ. I think I'm just going to go with an outboard speaker and sub EQ, (anti-mode) but then I will spend more time on these forums asking for help how to use it. Wait, I forgot I don't care for RC:eek:

Just so you fully understand, better implementations have Sub EQ which level matches and time delays the two subs independently. All XT32 implementations EQ both subs as one sub.

From Chris who seems to be the web expert on all things Audyssey:
MultEQ XT32 is the flagship version of our technology to measure and correct room acoustical problems. Sub EQ HT is a method we came up with to deal with multiple subs. If you only have one sub then it's not in use. The idea is to first measure each sub separately, then apply delay and level settings so that the two subs are now time and level aligned. Then we ping them once more as "one" sub to derive the room correction filter. I am pretty sure that the 70.3 is using this.
If you have both subs equidistant from the listening position, the time delay is not a big deal and you could manually level the two subs close enough, IMHO.
I am insecure buying this because I haven't determined final position for the subs yet!

The 809 price goes down to 529 now. I am torn between the 809 and 818. Is the XT32 (without individual subs setting) worth 150$? Are there any other differences between 809 and 818?

Assuming teh 809 has MultEQ XT, I found a good response to that on the Whirlpool forum!:eek:?:eek:?:D:cool:

About 10 posts down:

Whats the difference between MultEQ XT and MultEQ XT32?

There's two main differences, the first is precision. Audyssey MultEQ XT is no slouch; it's way more precise than just about any competitive system, using sophisticated FIR filters with hundreds of control points per channel. And yet incredibly XT32 goes way, way further with substantially more precision than XT — four times more precise for the subwoofer channel alone, where calibration is most beneficial.

The other difference is that some implementations of XT32 include the equivalent functionality of SubEQ HT, which basically means discrete dual subwoofer calibration.

Having said all that, MultEQ XT is so good that the law of diminishing returns applies — while XT32 is indeed significantly better, unless you have dual subwoofers or a room that really struggles with bass, you might not hear much difference.
