For those who are interested, Best Buy has the Denon 4520 for $999. Such a bargain for one of the best receiver. JT, jump on it.

Great deal if you don't care about ATMOS.

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.

Have you tried adjusting the phase/delay?

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.

^^ +1. One needs measurement gear to tweak the distances. I know I can't trust my ears. Here is my graph showing the big dip (more like null caused by my center and subs interaction) around my 80hz crossover with Audyssey distances setting and the dip..less after changing my subs distances. The result is very rewarding . Remember, Audessey and many other auto cal receivers only calibrate each channel separately but when you listen, you listen thru all channels combined which could cause dip/null as in my case. The distance tweak makes lots of sense.

Graph of my center and subs:

Hey Ace,

Which AVR did you get, the SR7008 or the X4000? Did you get the Parasound Halo P5 too?

I am coming to the conclusion that the best placement for subwoofer room mode wise is not the best placement overall.

By placing the subwoofer in the middle between the fronts, the overall sound is a lot better, yet room mode wise this is a much worse placement for me...

This sucks

Does anyone happen to know how much increase in output I'd get (at around 20 Hz) if I put my F15's driver and amp into the 4 cu. ft. cabinet from DIY Sound? I'm wondering if it would be a worthwhile "upgrade". Any chance I'd achieve F15HP-equivalent output?

No idea, but here are some easy ideas:
1) Put it in a corner (2x power!)
2) Put it close to the listening position (more 2x power!)
3) More aggressive subsonic filtering.
