I'm looking at a subwoofer PEQ, I know of the Velodyne SMS-1, Anti-Modes, and SVS EQ1. The Antimodes are in my price range, as would a second hand SMS-1
I have two systems
Home Theatre. Lexicon MC-8 V2 with SVS PC Ultra 13 (that has 1 channel PEQ)
Stereo system. Analogue stereo pre-amp SVS SB12+ (again 1 channel PEQ) with standmount speakers. I'm currently sending full range line lievel from the pre-amp, to the subwoofer line level input, which filters that at 80hz (fixed), then line level output from the subwoofer goes into the poweramp. So the poweramps only receive 80hz and up and the subwoofer 80hz and down. Adjusting volume/crossover dials to match (crossover dial is not for the line level in/out filtering, it's another one you can use on the subs cone) that's around 60hz as I generally I find 80hz from the sub a bit high and I probably get room gain from the standmounts anyway as its a small room.
PEQ on the subwoofers are disabled.
The antimode will be used in the HT.
I'm thinking the basic Antimode C model would be sufficient or the HT,however if I wish to move the antimode to the stereo system the stereo jacks would come in handy? Or could I use a Y cable from the pre into the antimode C? . I'm thinking though how would this function with the subwoofer "loop" which is filtering out bass? Would you run the antimode in the stereo system with the poweramps swtched off, so it'll do calibration and won't pick up the sound from the standmounts? And how would the 80hz filter effect the process? The subwoofer has the ability to run full range, so would you set it to full range during the calibration? (I don't think I would, just a question)
I'm not sure if this will work at all. Would it be best if the unit was more of a line level crossover, so it'll do the filtering AND the parametric EQ?
The pre-amp has two sets of pre-outs.
It is £300 though which is pretty expensive however I don't see myself changing the MC-8 for a long time for a new unit which has subwoofer EQ built in.
Reading the anti mode manual it says it has a 10hz sub sonic filter. The SVS also has a sub sonic filter, is this bad having two? On the SVS you can disable it. But can you disable it on the anti-mode? Which is best, filter on the anti-mode or the subwoofer? Also if you use different port tunings, this may be a problem if you can't disable it on the anti-mode? For example if you tune it to 20hz, normally you set the sub sonic filter to 20hz. But if you disable the SVS sub sonic filter because the antimode one is always on and at 10hz, is this much lower sub sonic filter a problem?
