Hey something I've wondered for awhile,

Lets say you have an Antimode or some sort of sub EQ. Now I run 14hz and hi damping on my F15, but is it best to run antimode EQ with it on low damping, and then when done switch back to hi? Then when back to hi, I let Pioneer's MCACC do it's thing/ I thought this might be the case, but I saw that low damping just drops off quicker. And if that's the case, I'm not EQ'ing correctly and should EQ with what I actually run.

What do you guys think?

Sorry if this was discussed, I didn't see it.

^^ Per Brian, he recommends running calibration with low damping then switch to whatever one prefers and NOT the other way around.

I use damping to match the timing of my speakers. I use mid damping for my Ascend 340s because it sounds like more of a match. However, when I had Gallo Reference Stradas (which are incredibly fast) in my system I had to go with high damping, there was no other choice. Low damping seems solely designed for that cinema boom. It's somewhat entertaining, but lots of other subs can do that. Rythmik's unique strength is tight, articulate bass, which may sound thin and dry to some, but it's much more realistic.

For the sealed F15, Brian's recommendation is, prior to running room EQ, set the amplifier to:
Rumble Filter - Off
Extension - 14Hz/Mid damping

I don't know about other "sub EQ" products, but the DSP AntiMode corrects for less-than flat amplitude response in the listening room as measured by the included microphone. If you set your Rythmik to Low or Medium Damping and run the Antimode, and then switch the Rythmik to High Damping, the Antimode will be correcting for a raw response that no longer exists. Not the optimum implementation of the Antimode's abilities, IMO.

Just want to add that for music, the Onkyo 5509 made the sub sound way better when compared to the Onkyo 818...

That's an unbelievable offer for a previous generation flagship!

For those not interested in Atmos, this is a real bargain. I wish this deal was available where I'm at.

Amazon has matched BB's price, but they're almost out of them now.

It makes a great companion to a pair of Rythmik subs.

I don't have a lot of placement choices for my F15HP, but before I try I wanted to know how significant the dips around 58hz and 90hz are.

I would explore your options. That's a massive, wide trough centered at about 90 Hz and spanning more than an octave.

Now, if you were crossing over to the mains at 50 Hz, then you're probably pretty good.

I cross the mains at 60 and the sub at 80.

This doesnt make sense. Do you mean the mains are set at 60 and all other speakers at 80?

The AVR is set to cross the speakers at 60 and the sub at 80 This was how the AVR's room correction set it.

You're using Anthem's ARC. It is setting a high-pass crossover on the speakers to 60 Hz. So everything above that goes to the speakers and everything below goes to the sub, as is typical for bass management schemes. In addition, it is setting a low-pass crossover on the sub at 80 Hz. This would only take effect on the LFE channel, since the aforementioned crossover means that the sub will never see 80 Hz from the bass management system (except what is left after the roll-off dictated by the crossover's slope).

Normally it would try to set the low-pass crossover for the sub at 120 Hz, but the in-room response is preventing it from doing that. Another reason to play around with sub placement, if you can. Also be sure that the Rythmik amp's low-pass crossover is disabled.

Been a while since I posted, but I just watched the second launch scene in Ender's Game on my FV15HPSE and it dropped. my. jaw. I live in a concrete loft and felt concerned for my safety. I can't WAIT to get a bigger place someday and get duals.

I have not but I believe Rythmik materials indicate changing the subwoofer distance (something different than the main speakers) has the same effect. Even though the sub is right next to the left main speaker I believe i have it set at a distance of 3 feet further than the left is set to.

My dual F12SEs are out for delivery, and I can't be more excited! New AVR, 2 channel preamp, subs, surrounds, TV in a newly remodeled/repurposed room. I can't wait to set it all up this weekend!

Yes, tuning the distance on the receiver is a good way to go. Try tuning it to maximize the amplitude at the crossover frequency. That will mean that they are in phase. If they are out of phase, you would get cancellation, and therefore a dip, at the crossover frequency.


The dip could also be caused by a room null, but tuning phase/delay/distance is the first thing to try.
