I think I spent a ton of time trying to get it to look good on paper. I think what I need to do now is checkout other things like waterfall graph, compression sweeps, etc. What are the best measurements to get a true picture of the sound? Going to ask in the REW thread as well.
I will be very interested to hear what you learn from alternative measurement approaches. I believe that there are speaker makers who can correlate measurements to what they can actually hear, in at least a somewhat predictive way. But, for the great majority of us, and perhaps for all of us, what we hear trumps what we measure. One of my favorite quotes on this subject comes from Floyd Toole who said that regardless of what measurements may tell us, a speaker isn't good until it sounds good. I think that we could say the same thing about our subwoofers, operating in our rooms.

I am not being facetious when I say that if you want to know how your subs sound best in your room, just listen. Over time, you will develop some clear preferences for your different physical arrangements, and settings, that have relatively little to do with the frequency response or for the waterfall graph. For instance, a house curve, and particularly one that emphasizes certain portions of the bass bandwidth, has very little to do with a flat FR. Measurements just tell us what we doing with respect to FR, or other audio characteristics. They don't tell us what we actually like or don't like. Only our individual hearing capabilities, and our specific psycho-acoustic preferences in our specific rooms, can do that.

I agree, but the point I made in the REW thread a couple days ago regarding a flat response isn't necessarily that the line is horizontal, but that the line, through whatever curve or flatness it follows, does not have major peaks and valleys. I consider my current frequency response as linked in my signature to be relatively flat, meaning no (or insignificant) peaks and valleys, even though it has quite a house curve on it.

That being said, just a "flat" frequency response (as defined above), does not tell the whole story as I have learned, and I have some more work to do through other measurements to truly get a sound that I like. I enjoy booming bass during scenes that demand it, but not when its obtrusive to other viewing moments. For example - a huge explosion warrants a loud and tactile boom and following rumble. However, background music with a low bass note should not make my ears hurt.

I believe the current boosting I am doing resulted in some boominess. Going to try PEQ tonight without the boost. I 100% agree that what we hear trumps what we see, but I would love to have my cake and eat it too.

I definitely think that you are on the right track. What a number of people including myself have found is that there isn't a single house curve that suits every movie/music genre, or every mood. For instance, while I like a very heavy bass boost for action movies, I don't care for that at all with the types of music I listen to. And, my moods vary, too. Sometimes, when I watch movies, I want more low bass, with a lot of tactile ULF, and sometimes I am really not in the mood for it. And, I back off my master volume and/or sub boost a bit. So, finding a single house curve, and combination of settings, that satisfies every genre and mood may be quite a task.

Some people may be able to use the same settings for everything, but I have to tweak mine a bit to fit the specific situation. I don't really find that to be a lot of trouble as I am very familiar with what my settings do and how to adjust them to fit my preferences of the moment. But, in my case, that is mainly a function of experimentation.

Mike

You raise a good point. The 2x4HD has 4 available configurations each with their entirely separate set of everything (Xover, timing, PEQ, etc). I have a Logitech Harmony remote that i can switch the config from. I think what I will do tonight is setup 2. One with booming bass for action movies (big house curve), one for articulate bass for music (flatter but slightly rising LF rise slope).

Depending on the outcome, I may even move the one sub back to the other side of the room, though I highly doubt I want to do that due to the huge 50Hz null i get when doing that!

That sounds like a plan. The second paragraph brings you back to the idea of a stand. If I just wanted to experiment, I would find something around the house that could be used as a makeshift stand--an end table, or even a cinder block, could work. You are just looking for something that could lift one sub off the floor by about 18" to 24". If you still prefer the stacked arrangement, no harm done. And, if you find another arrangement you like better, you could look for a more permanent and aesthetically pleasing stand. There would be lots of options for that.

Other than the stacking setup (which I barely squeeked by the WAF), my wife has nixed raising a subwoofer onto anything. Think "floating subwoofer next to the couch" - not a pretty site. At least having them stacked, makes one think of just a BIG A@$ Speaker lol

Enricoclaudio at Rythmik has said that they hope to have F28 subs available for sale sometime in the Fall, later this year. While it's certainly possible that Rythmik could eventually begin producing an FV28 or even an FV28HP, you would be facing an indefinite wait before that would happen, so if you are hoping to buy a sub soon, you may want to consider other options. It isn't far-fetched to imagine that larger-size subwoofers like an FV28 and/or FV28HP would be a logical extension of Rythmik's product line, but I don't want to start wishful rumors based merely on my personal conjecture! A reliable source for news from Rythmik Audio would be their official Facebook page:
https://www.facebook.com/rythmikaudio/
There is also this thread on AVSforum that discusses the new models that Rythmik is introducing:
JTR Captivator 2400ULF vs Rythmik Audio FV25
Enricoclaudio mentions in a post that Rythmik is developing an FV25HP sub, which will feature a 2000-watt amplifier, but it is still in the prototype stage and there hasn't been an announcement yet about when it will be ready for sale.
I already have a FV15 so I can wait. This sub is just for movies so I'm hoping a FV28 will be coming out to compete with the Captivator 218HT.

Are you going to have all subs tested in this location/position?

No, I don't want to block the TV and I think along the left sidewall I can find a better position for good FR. I do want to test them all at the same position. I think I will put masking tape down on the floor.

RMC-1 is totally out of my budget and way overkill for my needs. The max I can do in my place is 7.2. No way I can do Atmos in a 12" x 14" apt living room

Rythmik has such an attractive product line that I find myself wanting to buy almost every subwoofer model they sell. Among their sealed subs, the F25 seems like a great bang-for-the-buck value. I dream about owning a pair of them, though when I come back down to earth and look at the "tiny house" where I live, I realize that two F25s just plain won't fit inside my studio home. It started me thinking about a 12" version of their F25 (which would -- logically enough -- be designated as the "F22"). It would be similar to their L22 model -- a subwoofer with dual front-facing 12" drivers -- but instead of paper cones it would utilize Rythmik's 12" aluminum drivers, along with more powerful amplification. Depending on the selling price that Rythmik would need to charge to build a model like this, I wonder if a subwoofer of this type could prove to be a kind of "giant killer" by combining power, depth, and accuracy in a relatively compact enclosure that has a small footprint. I truly recognize that Rythmik is already doing amazing work with the excellent models they already offer and continue to develop, but this idea has me intrigued, even if it is only a hazy pipe dream that doesn't have much real-world practicality.

I wouldnt say rhythmik is any better than my 20 yr old velodyne sub, but that sub retailed for 2k 20 years ago...just depends what you expect.

As luck would have it, Rythmik is offering a special F15HP with "dark red stained real wood veneer" for $1400 on their "Clearance" page. This subwoofer is brand new (it is not B-stock). Here is the link:
http://www.rythmikaudio.com/clearance.html
There is only one of these models available, so if you want it for your very own you may want to act soon. Let us know if you decide to make the purchase...!
