If you use Audyssey you want to run it last. If you have EQ capabilities from any device you want to run a sweep and use your filters to pull down peaks. Then you run Audyssey last. If you have any kind of low shelf filter giving you your preferred house curve you want to disable it or bypass it because Audyssey will attempt to pull it down.

It's not double processing. It's using multiple devices as a team. Audyssey does its thing and you cannot adjust anything. If you can present Audyssey with a smoother frequency response then the final result will be better. I have graphs at home to prove it. So I take my raw response AFTER ALL NATURAL EQ WITH ROOM PLACEMENT AND ROOM TREATMENTS. Electronic EQ is SUPPOSED to be the final thing, the icing on the cake. For us with extreme systems we have invested so much we should never only run Audyssey (or other electronic eq), that would be blasphemy.

It sounds like you really need more EQ/DSP capabilities than just Audyssey. You have spent a lot so whats another 1k? It's like building a bad a$$ turbo motor and not running a fine tune on the dyno. Anyone who knows anything about turbo motors knows it's all about the final tune. It's staggering the performance gains you can get by a fine tune. So is the same theology with our HT systems. You can EQ each channel independently with the 88A! So each of those 215 RM's can each individually have the mid bass boosted. The frequency response can be manipulated for each speaker and sub you have.

Okay so reflection points. There is a very simple old school way of identifying each. Take a small lightweight mirror and put a little tape enough to hold it on the wall or ceiling. As you are sitting in your listening position and look at that mirror on the ceiling and you can see the Horn of you 215RM center channel then that is the 1st point reflection! It works very easy with two people because you can sit and have them move it until you see the Horn entry. It's that simple! I wish I was close to hear this 215's! I would so love to help tune your system. But we can easily do so using AVS. I didn't know anything before I came to AVS. I had no idea what a crossover was, etc. I'm not anywhere near the veterans on AVS but I can setup and tune any system.

If you turn off Dynamic EQ and try to EQ manually? what do you mean exactly? Do you have other gear with EQ capabilities? You won't lose distances/time alignment by turning off Dynamic EQ.
I'm just curious...if the 88a is last in the chain (after the avr w/. Audyssey) then wouldn't audyssey be what is sending a flatter response to the 88a and not the other way around?

I just invested more into gik room treatments that should be in shortly, and I was considering doing an audyssey pro cal, but the 88a or other mini DSp option now has me interested. So far, the two Seaton subs are workin out well, but I want to maximize the best room response as possible.

oops. nevermind! The input for audyssey is the test tones from the mic calibration (duh), so it makes sense to me now on how the 88a would fit in. Now it's just a matter of whether i need it or should use it vs just relying on my room treatments and audyssey pro cal.

I can tell you I have spent hundreds of hours pouring over so many different threads since I joined in Dec 2012. I have stated many times I am certainly no Mark Seaton type when it comes to knowledge on a scientific level of speakers and how sound works But I think I would qualify to teach some 101 lvl classes or "how sound works/HT setup for dummies." I say this humbly but also that my words may matter. The people I have come to trust and respect on AVS who have made the jump from Audyssey XT32 to Dirac live say the improvements are more than cocking your head to "see/hear" if there is really a difference. That the SQ is simply steps above, and the overall tune and one-ness of the system as a whole is simply several steps better. The ability to have different curves for different content and customization abilities are a bonus. I remember my first AVR was a Denon 3313i with Multi EQ XT. When I made the jump to XT 32 the biggest change was not the slightly refined bass but the overall teamwork and fitness of the surround sound as in all speakers and subs working together. It was not steps above but perhaps a singe step, noticeable for sure.

The end goal is not to have a fighter jet pan from your left speakers to center to right with some surround speaker action and sub action up front (or wherever they are placed). It is to mimic the jet flying through the room! To achieve this we need a finely tuned system where all speakers "become one." This is what I have read Dirac does that is so staggering a improvement.

I don't want my SUBMERSIVES to let me know they are working up on my front wall 1/4 and 3/4 points. I want them to become one with my mains and surrounds that I am not conscious of the speakers and subs working but that I am totally immersed with the current content. I know my gear is capable as a built engine is capable, we just need to proper tune now
