While both versions share the room correction software core, the studio version also includes an audio plug-in, and therefore doesn’t need compatible hardware to store and apply the filters like the home version. I will enjoy listening for a while before I venture into anything more complex and expensive.Now in its third generation, there are two versions of Dirac Live, one aimed at the home market and the other for the studio. You'll know when it's right by ear or can measure to confirm. Moving the monitors back/forward even 1/8" is clearly audible with double bass, drum etc. Since my monitors sit on top of the subs "location audibility" is not a problem, but time alignment is still important for proper transient response between the monitors and subs. Rather than go all-in like Dom, I bought a DBX 223 ($70 used at Guitar Center) similar to CDMC's set-up for an active analog crossover at around 120Hz. After seeing Amir's measurements I too wondered about rising distortion using small woofers and its audibility. Since the monitors in-room were good to around 60Hz., I simply set the crossover on the subs to 60Hz at 12dB and got a nice blend. I was in a similar situation as Dominik with a pair of Philharmonitor 2-way monitors (5.5" woofer) each sitting on top of a 12" active sub (DIY sealed GR Research servo). Try a few different configurations and listen with a few different types of recordings to see what seems to work for you. There will be some tracks that show up a difference ofc, depending on your XO frequency and slope (keeping in mind, as others have pointed out, that a 125Hz XO point does not mean that there is no output from the sub above 125Hz).Īnyway, I second what suggests. So, depending on your music taste, you're likely to be listening to primarily mono bass anyway. And in any case, many modern studio-recorded content, the low- and mid-bass will be more or less in mono anyway. Since you plan to place your subs beside your main speakers anyway, such a setup is out of the question. centred along opposing walls) that they can cancel primary room modes - but it only works if they are reproducing the same (i.e. Rather, subs can be placed in a room in such a way (e.g. The main reason subs are recommended to be run mono is not specifically to do with localisation (although the difficulty we have in localising subs at the frequencies they play is ofc a necessary precondition). Adjust Volume and time delay with REW and set values in MiniDSPĪre my thoughts / plan sound? Why would MiniDSP even recommend running dual subs as one summed up subwoofer?.Forward on the DDRC-24 CH1/Dirac1 to Genelec1, CH2/Dirac2 to Genelec2, CH1/Dirac1 to Sub1, CH2/Dirac2 to Sub2 (MINIDSP recommends: DDRC-24 CH1/Dirac1 to Genelec1, CH2/Dirac2 to Genelec2, CH1/Dirac1 + CH2/Dirac2 to Sub1, CH1/Dirac1 + CH2/Dirac2 to Sub2) (both subs would be connected with only one rca cable each).Should I use both subs as mono channel in a summed fashion like proposed on the MiniDSP homepage ( ) or can (and should) I run them in stereo due to the high crossover? I would prefer the second option. I also want to use Dirac for the final room correction. I know that this could make the subs position audibly but fortunately I can place them circa 0.5 m to the side of each of the Genelecs. Since the review of the 8030C in the Review of Amirm showed relatively high distortion starting at 125 Hz, I want to set the Crossover frequency at this. I want to build up a 2.2 System with the Genelec 8030C, Canton AS 30 (Active Subwoofer) and the MiniDSP DDRC-24HD as DAC / DSP / Preamplifier. I really learned a lot the last weeks simply by reading the great discussions here. First of: This place is really a refreshing source of wisdom regarding audio without the vague fuss surrounding it in so many other places.
