To get the best of both worlds you will need to move to an external Sub Equalizer. Note: Before running Audyssey MultEQ, be sure the subwoofer's controls are set with the crossover frequency at its highest value and the phase setting at zero degrees (unless your experiments have convinced you that you will get a better result with a different phase setting). Yes, that is the preferred method even if you have two sub outputs on the AVR. There is no difference in performance. For a list of new AVRs with Sub EQ HT please check here. I own 2 subwoofers. Per items 4. If they're going to be calibrated together, then would you suggest that I need to first run Audyssey with one sub connected at a time and get them to the same db levels by tweaking volume controls on the sub, then run finally Audyssey MultiEQ with both of them connected together ? Phase controls on subs are not useful because they only change the phase at one frequency and thus leave the remaining frequencies unchanged. Please be aware that digital processing in the subs introduces additional signal delay. Because of the sub's size-there's only one place I can put it in the room and stay married. Will any of the multieqxt AVRs EQ each sub individually? You need to get an SPL meter and dial the subwoofers at around 85dB (setting the levels), also playing around with the phase so that they're matched together, this can be much more difficult to do when both subwoofers are up front in the room. the distance setting is 30ft, with a +6db settings. Audyssey recommends sending the same signal to all three subs. LFE–THX or LFE+Main. Generally with dual subs, if what you want is not necessarily better bass or … If you are using the Audyssey Pro kit for both the Sub Equalizer and the Integra then you can ignore anything that has to do with the consumer mic. My left and right front speakers would always be out of phase to Audyssey since it is a multi-driver design (Raw Acoustics RA8). Adding delay to the subwoofer signal can sometimes help the subwoofer to integrate better with the loudspeakers in the room. Sub distance (delay) will usually measure longer. What do you think? Nothing to do with Phase. Many powered subwoofers have controls that are set manually. If you have two subwoofers, there are some additional steps to take: If the subwoofer provides a direct input (sometimes called LFE input) then it should always be used. After running Audyssey it set my Front and Center speakers as Large with the crossovers as Full Range, the surrounds marked as Small with crossover at 40Hz. So, I would not recommend lowering it. Do I need to connect the sub eq  (SAT) to  the CENTER channel on my AVR. The receiver does not give me the option to turn OFF LFE+Main. Yes I could go and remeasure everything with the sub phase reversed but hope someone could shortcut an answer. I have done this 2x now and still get lost. The "Bass Management Boot Camp" article about subwoofer setup that I wrote for the November S+V inspired an in-turn inspiring e-mail from reader Bruce Erwin. I own 3 subs attached to 3 sub inputs on a Denon AVP-A1HDCI. I have to agree with Bill that the connections for the Audyssey sub eq on page 10 are confusing. Should I put back to 80 Hz and have more sent to the sub? Of course, then you won't be getting the benefit of individual time and level alignment of the subs. If you wish to use processing in the sub, then it should be done first prior to running MultEQ. However, does it consider each sub then working together? Before - it sounded great. Try to set the volume control on each sub to the same position so they play at the same level as each other. I have Audyssey Sub EQ and Integra DHC 9.9 with Pro insalled. Most people bump up the subwoofer level after the Audyssey calibration. Surprisingly, the result was awful---I have, it seems, a lack of lows on my main speakers and the sound is somewhat annoying with female singers and horns. also i thought that it was a good idea to get the audyessy to set the subwoofer gain between -3db to +3db? Can you point me in direction of an AVR which has MultiEQ XT and the dual sub EQ feature? The suggested crossover frequency for the main speakers was 40 Hz, which I manually changed to 60 Hz after runing Audyssey. hi chris i recently added 2 subwoofer to my 7.1 set up, my subwoofer has a digital eq on it that has three setting. This can be achieved with y-cords out of one sub output on the AVP-A1HDCI or by setting the Subwoofer mode to "Mix". @Mauro  Lowering the xover will send less content to the sub where the MultEQ filters have 8x more resolution. A crossover consists of two parts: (1) a highpass filter that sends the higher frequency content to the speaker and (2) a lowpass filter that sends the lower frequency content to the sub.
