I would normally suggest using a typical y-splitter for this application, which doesn't use the resistors. Alternatively, some amps do offer a mono-functionality when using just (typically) the left output of the Subwoofer/LFE pre-out to left channel of subwoofer. Doing it this way would have the same electrical effect as summing the subwoofer, and then breaking it back out into an artificial stereo signal (if sub accepts L/R inputs). Just double-check that your devices can do it this way

so the issue then is just a stereo bass vs. mono bass issue if i get you correctly. thanx, kal.

so if i use the antimode cable, the subs would be stereo and if i use a summed Y cable the subs would be mono, if i read you correctly? the mains would still be recieving a full range stereo signal from the other preamp output? or are you saying that both outputs would be affected? sorry i'm not picking up on this, kal - it takes me some time ...

I do not know what the AntiMode cable is, so I can only comment on the use of a standard Y-cable or one with series resistors in it. The issue is whether your two output sets are independent, each with its own buffer/driver circuitry. In general, they are not in most preamps. In fact, the two sets are usually wired from a common buffer/driver with the equivalent of internal Y-cables.

If this is so with your preamp, then attaching a standard Y-cable between the two you use for the subs/antimode will also shunt together the two main outputs you connect to your amps. The result is that everything(!) is mono. That is why there are Y-cables with resistors in them. They serve to provide a mono signal for whatever use while still maintaining (almost all) separation between the channels on the main chassis.

Overall very pleased. I think if I spent some more time with it tweaking the crossover setting and speaker placement it can get even better.

I'm on the fence myself and appreciate your graphs. Now I'm really interested in your subjective experience.

With Anti-mode in there I am able to turn it up and can now hear/feel the lower notes. I always new I was strangling the Servo in this room position but this thing has helped immensly. Less boominess/ringing and more controlled and deeper bass. The servo is still impressive and only shows it's age in looks - that's why it stays hidden in the corner. I like that you can't see it either as it surprises people when they hear/feel the sounds. It was perfect timing as HTTYD and ToyStory3 were the first we watched after I got it dialed in and it was awesome! The lift features are cool too but were of no improvement in my situation. Could be useful for some though.

Great audio investment IMO

When I did the calibration with the 8033 I did not disable the PEQ. Would it be better to recalibrate with the PEQ disabled to let the 8033 do its thing. Or is it fine using the PEQ and let the 8033 handle other frequency issues? Or does it really not matter which way the 8033 is used in this regard?

2. And, from what I gather in this thread, I run the Anti-mode first, then run Audyssey in my AVR last, correct? And, I don't need to do any correcting for delays by adjusting the sub distance, right?

Thanks for the help! I'm really hoping to get my room to play nice with my equipment...

2. Increased dynamics and SNR for HighEnd use.

2) yes. anti-mode then audyssey. no, no delay adjustment, audyssey will calculate the correct delay that is introduced by the anti-mode. don't change this, even if it is different (which it will be) than the actual distance.

i personally am looking forward to overeating and overdrinking and spending a day recovering...
