Would appreciate any tips on the settings of the two subs shown below. I know I cannot possibly optimize the sound by just doing these but I ain't no HT nut and wouldn't wanna bother with all the complications. No need optimal sound, better sound good enough. Oh yah I forgot to post the settings of my AVR. Maybe tomorrow. TIA!

For settings on your Rythmik sub before and after your AVR's room EQ calibration, do pay particular attention to sections 2 and 4 of this document:
http://www.rythmikaudio.com/download/FV15_FV15HP_PEQ3_Installation_Guide.pdf

Also, you'll need to level/ gain match the 2 subs before calibration. I don't think u will need to do much phase alignment though due to being placed at same location.

Thanks so much bro! Yes I have read that installation guide. I won't be running both full range. Will set the Rythmik at ard 30hz and the KK at ard 60hz maybe.

LFE is below 120 IIRC. flick the KK LPF toggle to bypass and let it handle what the AVR passes to it, just don't set the LFE to go to mains in the AVR.

Consider swapping both to a stack of DXD1000?

You shoule set DXD12012 at default ( green indicator) as the Xover design as such similar like a high pass filter start roll off at around 30Hz ( to protect and also as Ref level for studio mixing ). So in this is safe and the KK should do the job well and your Fv15Hp use line in and set to the lowest freq ,as to level match is not a must in this case ,as you are trying to have each sub to run a given freq range without a external Eq device ,so your best betting is ,after this setting run a auto calibration , then play a moive and adj each sub for low rumble adj on the Rythmik gain to your liking and for puch and full body voice adj the gain on KK to you like , that is all you can do with min tools.


1) Rythmik rumble filter set to on after calibration.
2) PEQ set to off.
3) do away  the isolation of the Rythmik , listen and see you like it better?
4) stack the KK on top Fv15hp and face the driver to rear wall ( give a gap of 3") ,listen and see sound better in that locatiom?

Noted;
Kk DXD 12012 have 2 driver and each driver have it own amp to drive it , when both working the lower bass should be good enough for most setup , but if one of the amp is not working you only get around 40% of the Max output , so if your 12012 bottom out easy two thing you can check,
1) dis-connect any input cable RCA/XLR to the sub and only connect the power and power it up , wait for 20mins and it should goto standby and the LED turn RED , if not that indicate one of the amp's may hv a fuse blew.
2) check the fuse on each amp module and replace it.

Wah brothers, thanks so much! All points noted with deep appreciation! Now I'm keeping my fingers crossed that stacking the KK on top will have good results. Well even if no improvement, at least the wife will be happier. Now let me find the time to do all these!  ;D

I would sell one of it if I were u. It’s hard to have different design subs situated at the same location

1. The ported sub will have approximately 20ms delay or more

2. They will both be fighting for the same frequency

3. It will sound “rojak” because of different designs

4. Bass will sound muddied due to timing issues


If u used only one sub, or a pair of KK stacked, your system will benefit better. Best if you can measure the subs response at that location, so u can better decide which subs to keep. However, if u don’t have any tools, then The fastest way to do this is to first

Play a midbass scene with only KK on

Play a deep bass scene with rythmik on...

Compare and see which feels better, if midbass feels better , sell the rythmik and vice versa

Bro Chowbotak...I just noticed your signature, "I buy hifi to suit my music, not buy music to suit my hifi." I should have seen that coming...this explains why you are not into placement of subwoofers and speakers which by the way is the crucial to getting a good HT experience. :)

Tell me that I'm wrong with this ratio: 80(music):20(movies)? :P

 ;D

For me, I think 90% music and 10% movies is more accurate. Yes I think my signature does apply to my HT as well. Some of the movies I watched I don't even switch my HT on and I don't watch movies I don't like even if it has superb sound, I only watched their clips in demo discs ;D

Just now I stacked the KK on top of the Rythmik and changed some settings as advised here. Hmm I got slightly more mid bass punch man. Sadly I will be taking down the KK as it looked rather unsightly with the cables at the back exposed. I am quite sure I can improve the sound (to MY ears ;D) somehow with a little bit more adjustments here and there. For HT I am very chin chye, I don't do much tweaking. I don't spend thousands of dollars on acoustic treatment and sound proofing like I did for hifi. Some years ago, a sound consultant came to my place to do measurements of my hifi and HT. For my hifi, the measurements were good, just needed a little tweaking. When he measured my HT he said, ah this is not right, nt right and proceeded to adjust my settings accordingly. I listened after he did that, I told him to change back to my original settings. Yah I'm pretty fcuked up I guess ;D

LoL...I rest my case. :P

You can't improve your HT experience if you are not prepare to make "changes" which for the most part unlikely to be what you want. I think for you, just enjoy what you have :)

Thanks bro. As of now I think I am inclined to getting another 12012 to stack. BUT the downside is that I may not want the side woofer to face the wall as the back of the subs and the cables would be exposed, facing my front door argh! I wonder why they design it this way  ???

Both are solid subs bro.

Add on 1 more KK 12012 Stack and listen first.
If you like the KK stack combo, hear it with Rythmik On and OFF and see if you like the sound signature\feel.

Can look out for other placement position for the Rythmik in future. ( Not side by side bah:) )
Most important is Enjoy the HT journey! :)

It doesn’t matter much really where the Drivers are facing. What matters is it’s corner loading for the KK subs, KK subs has got very good transient response , u won’t have to worry when it is stacked at corners and if u have EQ to bring down the peaks, the second stacked subs can cover for some SPLs on the null areas, not much but since you can’t move subs much, that would be your best bet

I would advice not to stack it on the fv15hp , they will mess everything up. Gotta live with dual fv15hp or dual kk or single , mixing it and placed at same location will be worse off than a single unit

Trust me, I’ve owned both and just integrated the kk12 and rythmik lvx12 recently last week, I’ll share some of the graph details and why I think it won’t work...

The only way for this combination to work is to place the kk subs at a location where midbass has a peak and fv15hp subs at locations where deepbass has peaks, integrate them that way and they will supplement each other better , they will then not be fighting for the same frequency

U're right bro and I'll need to test the different combo for some time. Let me see how troublesome will that be. . Wife will shake her head again ;D

Corner placement will be impossible for me bro cos the only corner space I have is the area next to my main door  :(

So will it be worthwhile to have 2x12012 stacked if I cannot locate them in a corner?

Lol my Wife has been shaking her head since 2 years ago, when I was swapping front back left right, stack unstuck, co locate etc... so much so that, suddenly, everything is like ok” that’s expected”... and the head shaking stops... lol

Yes stacking same subs will help, it’s the way to go, but u will need EQ to cut away peaks and resonance, it will help in some way, then just live with some nulls  at certain frequencies, if placement is an issue, that’s the only way... no other way...
