Adding into that...the only receivers (by ANYBODY, not just Onkyo) that have sub EQ are Audyssey Multi EQ XT32.


Although, without using Audyssey(and in going out and buying a SPL meter), you can EQ your sub manually.


OR with...

PARC

Antimode 8033


And the many other "separate" EQ programs out there.

How do you EQ a sub with an SPL meter?

I believe any receiver with Audyssey MultiEQ & up do have subwoofer eq algorithm, albiet not as sophisticated as XT32.

Got this from THREAD :The Onkyo TX-NR3007/TX-NR5007 common questions/issues/hints/answers


In August 2010, Audyssey launches a new technology called Audyssey Sub EQ HT and that

technology was already present in the MultEQ XT products released by Onkyo one year earlier.

Allthough Sub EQ HT is included in all new MultEQ XT32 AVRs, Sub EQ HT has nothing to do with XT32.

It's a separate function and can be used with any version of MultEQ. The xx07 were the first models.

Yes i believe you correct , ALL" Multi EQ" have it but ,( unless it has changed recently ),.... but the XT 32 goes an extra step and" PINGING" them together ( I think it means callculating how they react together also. )

That was not the question. Certainly, all MultEQ versions will EQ a single sub channel but only MultEQ XT32 has Sub EQ HT.

But is it implemented with any non-XT32 products?

Receivers with manual subwoofer EQ...


Integra dating back to the X.8(would also assume Onkyo included them) and probably even earlier...


I'd have to check, but I think the Denon AVR 4810 has manual subwoofer EQ(I use the EQ tuning the Velodyne came with)


Most of the time if I find a room that needs subwoofer EQ-ing beyond finding the "right place to put it" I use Antimode 8033 or PARC. Both of which allow tweaking.


Which assuming, Mr. Rubinson, you are still familiar with PARC.

I will have to check but such are usually too limited for the task. Too few and fixed bands (63Hz, 125Hz only in the Denon) with fixed and undefined Q.

And with sub-PARC. All 3 suggestions are good ones.

A (one third octave?) graphic EQ with only five bands (“25Hz”, “40Hz”, “63Hz”, “100Hz”, or “160Hz”) of which only three bands are below typical bass management crossover frequency is not precise enough for effective subwoofer EQ.

Sure it is. If you can't EQ a sub with those three bands...


MOVE YOUR SUBWOOFER...


No amount of "correction" makes up for lousy placement.


You also have to remember that I've been dealing with subwoofers since David and Goliath. We didn't have "room correction" back then. I wouldn't let Audyssey mess with a Volkswoofer.


In my opinion...


Audyssey=Gelding.

Move your sub until exactly three room modes precisely align in frequency (and Q) with 25 Hz, 40 Hz, and 63 Hz? Good luck with that.

Yep, that is your questionably informed opinion. Others far more astute than you disagree.

More astute than me disagree? Ok.


Have you ever heard the David and Goliath? How about a Volkswoofer? How about a Klipsch subwoofer based on the Klipschorn?


Yes, back then, when M&K made a splash, everybody else jumped on the bandwagon. Klipsch made(but as far as I know never sold it) a "Hornsub" to pair with LaScala.


So, those of us with subwoofers since before 1980 have no idea how to correct for anything? Yeah right.

Guess what guys ... we were wrong .... Sub EQ HT actually IS implemented on some Onkyo XT models ....


I just reviewed the Audyssey thread and as noted in Chris's posts below, Onkyo actually started introducing Sub EQ XT in some XT XX07 models (1007,3007,5007; partially implemented) and it was fully implemented starting with some XX08 models.

No. As I have said several times Sub EQ HT has nothing to do with XT 32. In fact, it appeared in earlier models including yours (Integra DTR 80.1) but did not receive any marketing mention. Have you used Audyssey on your Integra? I'm surprised that you didn't notice the Sub EQ HT functionality of pinging each sub separately and then together as one.

Sub EQ HT is independent of MultEQ. It can work with any version of MultEQ including XT32. It is a method for properly blending two subwoofers. Each sub is measured individually and the differences in level and delay between the two subs are corrected. Then the subs are treated as "one" and MultEQ pings them together to create a single filter. We found that this gives better results than creating a filter for each sub separately.

SB your message the other day made me check with Onkyo. Much to my surprise they only implemented part of Sub EQ HT in the xx07 models. Sub EQ HT is basically the functionality that comes in the stand-alone Sub EQ processor from Audyssey. In the PC software you can run the two subs as 1-in to 2-out (which is what I was referring to earlier) and 2-in to 2-out. Well, apparently Onkyo only decided to implement the 2-in to 2-out mode. They added the other mode in the xx08 models. Confusing? Yes... I apologize for adding to the confusion. You still have a very good product with the ability for MultEQ to individually control the time delay, level, and room correction filter of each sub. This is a feature that took a very long time to convince manufacturers to implement. The 1-in to 2-out mode is a further enhancement that was added to the xx08 models.

Did you not note my use of Antimode 8033 or PARC above?


Both of those ALLOW manual control...greater than Audyssey/EZSet/MCACC/YPAO give you.


Also, depending on the subwoofer, you get subwoofer EQ that is also manual with greater control than you get from the AVR.


Also, you must have missed "subwoofer placement 101"...


Response valleys are NOT correctable...other than by MOVING THE SUBWOOFER.
