Axiom Home Page Forums General Discussion Home Theater How many of you keep your autosetup EQ on?

Fred, after about 17 years of development, Sherwood Newcastle finally released the R-972 with Trinnov for general sale some months ago. Both Sound&Vision and HomeTheater Magazine published generally favorable reviews and lab tests a couple months ago.

As the tests show, as far as basic amplification goes the R-972 is a standard unit many examples of which are available for less than half the price. The difference of course is Trinnov and further study is needed to determine if the room EQ is as good or better than Audyssey MultEQ, and if the remapping feature to compensate for poor speaker placement is effective(assuming that it's needed in a particular setup).

Thanks for the links John. It looks like Trinov delivers the goods. Given all the talk over Multi-EQ I'm surprised this receiver has not come up as a topic before.

Good morning,
This is my first post and I was wondering, for those of you who do use Audyssey, what crossovers does Audyssey pick?
I am researching and I am looking at the M80's and the VP 180.
Thank you for your input

It picks the crossovers based on the readings it gets from the speakers while testing during setup. For example my M80s get a 40hz crossover while my M22s get 80hz for their crossover when used as my mains all in the same room and placement.

Thank you!
I am currently using MultiEQ XT and an AS EQ 1, and it seems that Audyssey sets a crossover about 10-20hz over a speakers spec'd lower range with the setups I've tried. Your results seem to confirm this.
Thank you again, this is exactly the type of information I'm looking for :-)

Prblm, welcome. For example, Audyssey measured that my M22s in my room setup were capable of strong output to below 60Hz, and using the receiver manufacturer's standard, the crossover was set at 60Hz. Nevertheless, since I wanted my EP500 to handle more of the low bass load and my M22s less, I manually reset the crossover to 80Hz. Resetting the crossover higher(but not lower) is okay since Audyssey would equalize theoretically as far down as the original setting and no equalization is lost if a higher setting is actually in effect.

My Pioneer MCACC eq is always on the setting that (supposedly) optimizes frequency response. However, I tune to ear the volumes and crossover settings of my 3 subwoofers, turning them down until I stop hearing low frequency booms.

The Pioneer 1020 should have half-way decent standing wave attenuation.

If you're in the mood to tweak try this:

Get the receiver to produce the pink noise on the sub-woofer channel. Use an SPL meter very near to each sub (like less than 1 foot away from the cone), so the influence of the others is minimal, set them all to the same output level. Now run the multi-point standing wave analysis selecting three points in the listening area (they'll be in the order of 2nd, 3rd, and then primary). Check the that receiver's sub output level is 0 or slightly positive (if it reads negative go back to the first step, and adjust each sub to a lower level).

That should get you even output, and the receiver will be killing 3 of the boomy frequencies (usually standing waves created by the length, width, and height of the room).

Thanks for the suggestion on how to use standing wave filtering with multiple subs, Chris.
