Is there a difference between these two features and if so what are they? I see some AVR's offer both of them so I am trying to sort out if you have XT32 why you would need SubEQ HT.
Example, the Integra 70.3 doesn't list SubEQ HT as a feature but the Integra 70.2 does. Is one going to be different in regards to how it treats multiple subs?
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.
Thank for the quick respone.
So just because an AVR has MultiEQ XT32 doesn't mean it has SubEQ HT BUT if its has SubEQ HT it has to have XT32? Further more of you have 2 subs you would want SubEQ HT because it handles them differently then just MultiEQ XT32 on its own?
So far only AVRs with XT32 have incorporated Sub EQ HT, but it's not a requirement. Any AVR maker that wants to add the Sub EQ HT functionality can do it.
So just because an AVR has XT32 doesn't necesarily mean it HAS SubEQ HT?
Hi Chris, thank you for clarifying that SubEq is not a requirement of XT32, a lot of people have the impression that it's a standard feature of XT32. I have a Onkyo TX-NR3009 the follow up from the 3008. On your site you have the 3008 listed as having SubEQ but not the 3009. I would be very surprised if Onkyo deleted this feature especially since the receiver has two sub outs, something that would really benefit from SubEQ. I've read how SubEQ works and going through the XT32 setup on my receiver it describes exactly how it calibrated my two subs. First it asked me to calibrate my subs individually to 75db. After that the first ping sweep measured each sub individually and then after that as a whole. This to me indicates that the 3009 does indeed have SubEQ even though not listed. Can you please confirm if the 3009 either has SubEQ or not?
Also you stated that so far only XT32 receivers utilize SubEQ, however on your site you list the Onkyo TX-NR5007 having SubEQ and this receiver definitely doesn't have XT32.
Thanks Chris in advance.
Thanks for all of the input responses. Would it be possible to list the AVR's here that actually have SubEQ HT in them currently?
Bill, you can find the list here:
that list doesn't contain any of the 2011 Onkyos, only 1(?) from 2009 and 3 from 2010, so I guess it needs updating?
It's being updated as we speak. All XT32 Onkyo models from 2011 have Sub EQ HT.
Thanks Chris, I find it very refreshing how you take time out of your day to answer these sometimes mundane questions. It's nice being able to dialog with the founder and CTO of the company.
Chris my denon 3312ci has 2 sub outs but only mutilEQ XT , will I need an external eq to use 2subs?
Both subs are Klipsch RW-12d
Hi John, you don't need an external EQ for the subs. Just set them up to be at the same level and as close to the same distance as possible and then y-cord out to them from the Sub Out of the 3312.
Ok thx Chris, so dont even use the extra sub out from the 3312 i got it. Is there anyway to purchase the firmare to upgrade to XT32 for the 3312 ??
Extra sub out is basically an internal y-cord so either way is fine. Unfortunately there is no way to upgrade firmware to XT32...
Thx for all the help Chris
Chris, I was wondering if you could (or let someone) update the "product catalog".
I am missing the new Onkyo 818 in the list which comes with MultEQ XT32. I was wondering if it really supports two subwoofers individually or if the model is using a y-cord. (I guess I am asking if it offers SubEQ)
Our team is working on updating the catalog. It should be up soon.
I am wondering about the exact thing as Pierre. Rumor has it that the Onkyo 818 does not include SubEQ HT, this is weird cause it includes two subs out and the XT32. Why would they drop the SubEQ HT on a receiver that has so good specs to begin with? I think a lot of people are waiting for this "do it all" receiver so a quick clarification on this subject would be usefull.
I has now verified that the 818 does not have Sub EQ HT. This is a decision made purely by Onkyo. Although it provides two subwoofer outputs, these are not independently controlled as required for Sub EQ HT.
Onkyo have released the 1010, 3010, 5010. None of their literature mention subeq HT. Can let me know if any of these products have the subeq Ht?
The 5010 will support SubEQ HT
Thanks Chris for the quick response.
G'day Chris, Would you be able to confirm that the 5010 has SubEQ HT and that both the 3010 & 1010 do not have SubEQ HT. I know you answered it above but a few other people would like some clarification.
Hi John, yes this is the info we have.
Chris, I noticed Onkyo 5010 has 4 sub outs. Does this mean that the SubEq measures 4 subs independently? Jay
Sadly the 4 outputs are really only 2. They are internally y-corded in two pairs.
Thanks Chris. Is it something that will end up in future versions of Audussey technologies?
Hi Jay, this is already available from Audyssey. However no AVR maker has yet allowed control of 4 independent subs.
