Very good to hear. Did u end up increasing the volume on subs or just as is ?

Most will feel the need to boost the bass a little after getting the problems peek away in the room, still the bass should be more powerful and have a tactile better feel to it.

Works wonderful on my dual 3x12

Been interested in getting an Anti-Mode ever since I ordered a new subwoofer and my avr has no correction program. Can't find any inexpensive boxes for sale anywhere. I do have a SPL meter though. Been thinking about buying directly from VLSI. Cinema would be $307. Don't understand what the S-II would do for $81 more, and if I need that. On the VLSI store website, there is a place for a coupon code. Anyone know of a coupon code?

I set the volume about halfway up on my sub and left it there for both the Antimode and preamp's equalization routine. It ended up at -1, and my SPL meter showed it right at 85 dBC, so I left it there.

Just out of curiosity have you tested both the flat and the subsonic filter modes? According to the documentation the subsonic filter mode is the default after initial calibration, but I would assume flat is what most people use?

Been thinking of trying one of these but after reading the manuals and researching I'm a little unsure of why subsonic filter would be the default.

From what I read in the manual, the subsonic filter is on by default to protect ported subs. If you don't have a ported sub, or have a beast of a ported sub, I'd go with the Flat mode, which is what I ended up setting mine to after the calibration.

I use the Dolby Atmos Amaze Trailer as my benchmark. The bass is insanely deep and powerful when the lightning strikes and thunder cracks about a minute into the trailer. Going from subsonic to flat was the difference between Wow! and Holy ______! With most material, I haven't noticed much difference, though.

I see, so what is considered a "beast" of a ported sub? I have a PSA 15v for example. Should I be concerned with any potential damage from running a flat calibration?

On the antimode 8033s-II, after cal the subsonic is auto engaged. You can disable it, IF you leave the cal as is.

If you want to engage the low freq LIFT function (think house curve) then the subsonic turns back on and there is no way to disable it. Part of the reason I bought a 8033, but then also bought a Dual Core. Well, that... and dual subs, PEQ function, etc..

Not interested in lift modes. Just wondering if there is any risk to calibrating and then running flat as it seems that the levels are much higher on the low end of the frequency range that way. I guess I thought there might be some risk when I read through the manual and saw something about protecting a ported sub and that the subsonic mode is default.

No risk whatsoever flat.

If you had some cheap POS sub, and cranked the low end via lift, AND put on a worn out badly recorded record (yes turntable) that put out distorted low end...well, then THAT is what the subsonic filter is for.

Is the dual core worth the extra investment when I have the anti mode already ? I'm running 2 SVS PB13 Ultras in a medium sized room not really built for home theater use.

This question was first generated in a thread I posted in "Help with EQ-ing my Sub". I just realized there was an Antimode thread, so here I am.

OK. Here I go again. Just when I thought I was making a move for a new avr (Denon x2200W), I started rethinking the Antimode option. Mainly because I figure I'm keeping the NAD regardless and it would be nice to pair it with a DSP of some kind. I've looked at the DSPeaker website and read the manual, but I'm confused with the 2.1 hookup diagram. My NAD C370 has pre-outs. But if I use the pre-out to connect to the Antimode, then connect the Antimode to my sub through the line out, doesn't that leave my mains nowehere? Don't I have to return the signal to my NAD through the pre-ins? This question reveals my inexperience with these matters, I know. But I could use a hand figuring this out in my head before I decide to go this route. A simple line diagram would be helpful with your explanation; I gotta "see" stuff to get it.

For more background to my questions, you can take a look at my original, short thread. Thanks ahead of time.
