Room EQ and subwoofer management hardware: Anti-Mode X2 by DSPEAKER

[usul]

I own both the X2 and the dualcore, plus two antimode 8033s-II (subwoofer mono correction) and I’m very satisfied with all of them.

The X2’s correction is noticeably better than dualcore’s, and goes higher (about 2khz), instead of 500hz (max correction limit on dualcore). And it is more effective in correcting dips and hump. But most of all, it’s much better in setting the overall bass level after calibration. Plus it has a independent subwoofer output and is capable of 2.1 correction (2.0 on dualcore).

But I will keep the dualcore as well and use it for pure subwoofer/bass driver correction. I use two 8033 for stereo dipole bass correction in a 3-way OB speaker.

I feel Antimode got a undeservedly bad reputation bcause of the ASR dualcore SINAD test. Just testing SINAD on a swiss army knife of a device like the dualcore is very misleading and uniformative. Why just test for SINAD on a standalone device (no computer required) that for under 1k does/has:

-room correction

-dac/preamp with digital pass through (optical)

-is capable of simple room measurements without a computer

-PEQ

-variable bass/treble tilt

-subsonic filter

-low pass/high pass (6/12/24/48db LR)

Question.

does it eq 2 subs independent or as one?

If you can do eq seperste per sub, what mode do you use?
2.0 or 0.2?

I ask, as I have 2 subs and use 2 sub outs of pre amp that can time align both subs..
Want to make sure 1 of these x2 can do both subs and still allow me to time align.. Or do I need 2 of these.. One per sub..

Basically, I want stereo sub in, to stereo sub out.. With eq per sub independently..

 

[Willem]

Two subs is better than one, but I am not so sure stereo subs is a good idea.

I actually am using 2 subs for just sub channel on pre amp..

One sub is in front of room and other in back.. at different distances..

Hence why I need to time delay each sub then eq...
But both subs get same signal not stereo.

Are you looking to eq the entire system or just the subs? If the latter, I would look at Antimode 8033 instead

Just subs for now..
But who knows in future..
Want to spend once...

Both X2 and Dualcore are capable of stereo subs, either as 0.2 or 2.0 fullrange. Which is better depends on the setup and room. Fullrange correction with X2 is 2Khz and 500hz with Dualcore.

Then X2 is the best choice. It can do 0.1/0.2/2.0/2.1

The X2D version is a digital in/out processor that does 2.0 correction of the whole system. It's purely digital so you can use the dac on your preamp.

 

[Paffi]

Can recommend both devices (X2 and X2D), as I have both - unfortunately, there is no measurement available for.

Does the X2D have fixed volume or variable on the digital out?

Of course variable, it works like a digital preamp.

 

[Andysu]

it ain't room EQ that is total misleading , its really speaker EQ that should be applied up close to those all crooked speakers frequency response , room EQ is more like applying materials to the walls and ceiling to alter or slightly change the frequency response within a ideal room shape other rooms like mine and yours firstly need to be altered before applying carefully placed materials , othewise again i don't want to hear another word that , this EQ here or dirac , arc is a room EQ it ain't its marketing word used in such a lousy way of brainwashing , its impossible to EQ a room its not like flight deck on space shuttle pumped up to certain PSI that is equal , and this , trinnoiv rubbish wave forming EQ is just another EQ
pink noise or direct frequency sweep REW on processors amplifiers shows smoothness , do that on speaker its all crooked on those so called bs high end game speakers costing £1m , EQ should be applied with close up of microphones to each crooked speaker part with around 20,200 PEQ filter bands which is a lot otherwise what's the point cutting corners with octave smoothing which is just like magnifying glass focus or telescope looking at distance object and being sharpen focus to see its form

i know there are bs ing insiders on this site crawling around that will bs even more and i'm done past their bs that these EQ are room correction , it isn't and you know that so so many others that also know this

use it to correct the speakers and apply materials to the walls and ceiling that are going to do very little since wavelengths on upper highs get very narrow or just deal with it ,

Does anyone else than @oldvince have experience of running the X2 as a DSP processor rather than a pre-amp? My plan was to hook it up between my current pre amp and power amp, but oldvince's post makes me worried. If I need to set the X2 output 15 dB lower than my current per-amp's in order for it not to clip, then I will have to rethink. Adding some kind of head-amp in the chain to increase the gain doesn't feel like a plausible solution.

 

[Paffi]

Yes, I did and had no issues. If I were you, I would just try it.

 

[damaged_goods]

Did you max the volume on the X2 (-3dB?)? Taking into account the attenuation of the room mode peaks, the total gain decrease would probably end up somewhere around -5 to -10dB in that case, which I could live with...

 

[Paffi]

Yes, at full volume. It may also depend, on how much some frequencies get lifted after the calibration, I would adjust that accordingly.

 

[damaged_goods]

Both X2 and Dualcore are capable of stereo subs, either as 0.2 or 2.0 fullrange. Which is better depends on the setup and room. Fullrange correction with X2 is 2Khz and 500hz with Dualcore.

What is the upper limit for "low-frequency correction" on the X2? Is it possible to set a custom correction frequency range?

 

[Peas]

Does anybody happen to know the latency of the X2?

My AVR struggles to measure the device and assumes a very unusual speaker distance of 9.00 meters, which is the maximum possible.

By ear, I would say around 4 ms delay as adding 1.2 m to the physical distance of the subwoofers, the bass is the loudest and most accurate.

I have X2 and X2D. The latter one, together with good dac, is dead silent. The X2 with analog outputs adds some little noise.

I offered Amir both models for testing (including a small sourround preamp, but unfortunaley, he didn't respond.

Does X2D also work in 2.1? I know the regular, analog X2 does, but I am interested in the X2D model to use a separate DAC, but I want the subwoofer integration too.

Also, assuming X2D works in 2.1 mode, would I still need the Ant-Mode 8033 Cinema model that I already own, or would be able to sell that and just use the Anti-Mode X2D?

It works in 2.1 mode, and you would no longer need the 8033.

 

[Willem]

Indeed. The DSPeaker site mentions that the X2D has both a digital output for the main speakers and an analogue output for subs. Compared to the similar WiiM Ultra it has fewer inputs and lacks an inbuilt streamer, but has more advanced room equalization and subwoofer integration.
