Recommended initial subwoofer settings

These settings are a good starting point for getting the maximum performance from your Rythmik subwoofer.

The recommended initial setting with HT:

0) Low pass switch set to EXT/12 (not 80Hz/24).
1) power voltage set to 110-120v (for US, Canada, Mexico)
2) PEQ (Parametric EQ) set to Off
3) PEQ Gain doesn't matter with PEQ set to Off
4) PEQ Bandwidth doesn't matter with PEQ set to Off
5) PEQ Frequency doesn't matter with PEQ set to Off
6) Delay adjustment set to 0 (will be adjusted from HT receiver).
7) Crossover adjustment set to max first (then gradually dial down for best integration).
8) Level at 12 o'clock to begin with. Gradually move it higher to balance sub with front speakers.
9) Extension filter switch: 14Hz
10) Damping switch: high.

9, 10 can trade off max extension vs max output. If one really likes to play loud, he needs to set to 28Hz/low damping.

Ok, I'm confused a bit. Why have the calculator, if in #6 you have

"6) Delay adjustment set to 0 (will be adjusted from HT receiver)"?

Are these releated?

Thanks,

Jeff

Setting it to 0 and let the AVR's distance menu do all the required phase/delay adjustment. It does not suggest 0 delay is the final solution.

What about initial settings for a 2.1 system without an HT receiver?

Same initial setup recommendations...

8) Level at 12 o'clock to begin with. Gradually move it higher to balance sub with front speakers.

I don't understand this part. This is not about setting the volume, right?

Yes, LEVEL is the volume level (gain) of the subwoofer. Ultimate volume is controlled by the AV receiver, preamp, or integrated amp.

I see. Then I must have miss understood step 7?

7) Crossover adjustment set to max first (then gradually dial down for best integration).

I thought that was referring to the volume.

Rythmik has a curious recommendation to use the crossover to fine tune or further integrate the subwoofer with the main speakers. As the crossover is usually set by the AV receiver, or in my case a stereo preamp with bass management, it seems it would be unnecessary to use the crossover dial on the Rythmik at all. Indeed, most manufacturers and experts recommend setting the subwoofer crossover at the highest frequency to "get out of the way" of the AV receiver crossover. But, Rythmik are the experts when it comes to their subwoofers and if they say one can further integrate subwoofer and speakers by adjusting the subwoofer crossover I'll try it. Good Luck!

Thank you! I've found the exact same info from a previous thread.

I should better look up first before asking questions. :D

By the way, is there a music list for testing subwoofer settings?

Thank you for the list!


Below links helped me understand the recommended setting further.

Hi Dave and other members, is my understanding correct that to setup the sub into a 5.1 system,
1. First use Dave's initial setting for the sub in post 1
2. Run thru the AVR room EQ (such as YPAO in my Yamaha)
3. Change all speakers to small, if not already, set crossover to 80 or 60
4. Change the sub distance by using the distance setting in Rythmik's sub tuner java app
5. Increase sub volume level as desired to fine tune.
6. Turn down sub crossover to fine tune

Thank you in advance.

This procedure is correct :)

What would be a good LPF setting for my LV12r paired up with CMT-340 se fronts and htm-200 se surrounds if I do equal 2 Chanel music and surround sound home theater? Also, would Med 22hz be a good compromise with the damping setting since I do both or is 19hz low still recomended? Enclosed room 13x18X8. Thanks.

I'm running a 2 channel system in a corrected listening space.

I have my F12SE crossover set to about 50 - 55 hz in concert with Sierra 2s, with gain about 50%

It sounds very good to me, with lots of detail coming from the Sierras, and a lower end "punch" from the sub

Any reason to consider a different setting(s)?

I am looking at dual L22 subs.

What would the settings be for music? I don't care about house shaking LFE. Nor,do I want to spend hours trying to tweak little knobs behind the unit.

Damping = high

Thanks. I have found that if anything has too many adjustments I have a hard time getting it dialed in. I am close to buying Subs now...a hard decision for me. I have mentioned our rambunctious hairy Jack Russell Terriers before. For this reason, SVS Subs are still in the equation due to their metal grills.
I have had several servo subs, and realize the advantages.

Our new home is behind schedule, and this has given me several months to decide. I am to the point where my brain is frozen.
