That's a cool way to demonstrate driver excursion vs. frequency.

How loud were those tones playing?

I posted the graphs comparing hi/med/lo damping a week ago or so. I definitely prefer 14/hi 1 port even for movie but I have 2FVs in a ~2300 ft^3 sealed room. I can tell the difference between hi and lo damping. Hi just sounds cleaner and tighter. In your case, it might not be a bad idea trying 2 ports open. It's still 18hz tuned which is still low. In my case however, I tried 2 ports open, reran Audessey, listened to a couple songs and a few 5 stars bass movie clips, the result is

Try all the combination settings and stick with the one you like most. This is another beauty of owning a Rythmik sub - so many settings for different outcomes.

Oh, regarding front projector, you do not experience true cinema till having a 120" inch screen or larger. My $1k 3D 1080p projector gives me just that for the last few years now. It is only about $700 now plus another $2-300 for the screen. Big sound comes with big picture.

It also depends on how far you sit from the screen. In my case I sit 8 ft from a 92" diagonal screen.

Started working on the wife tonight. Planted the idea. Will see when my bonus comes in October. Been debating the 9.2 channel receiver vs. a projector and retractable screen for living room all day lol.

Think I should try two ports open because it's a single FV and the large sized room? And on High or Low? Why? Thanks.

To get the same immersive effect I get from 8 ft you have to go with a 135" screen.

Not even sure if there's enough room between my speakers for that large of a screen! Haha. Also assuming that would be very expensive. Especially if I want it to be able to roll up into the ceiling.

It depends on how picky you are with screens. I have had so many screens in the last 15 years that I don't remember the exact number. Maybe around 10 screens? The one I like better is my actual Carada Criterion screen. The second place goes to a motorized tab tensioned Steward Filmscreen that I had in my house in Venezuela. I had also an Elite tab tensioned screen that was OK but didn't like the surface material. I also had some Dalite Cosmopolitan Electrol but didn't like them due too many waves on the surface. In your case I would recommend a motorized tab tensioned screen. Those can cost between $800 to $3000 depending the manufacture, screen material and size. Fixed frame screens are cheaper and also the best screens if you are really picky. Then you have to consider the projector technology you want to go. If you go with something like the new Epson 5040 (faux 4K) or a JVC RS400 (Faux 4K) then you have to get a receiver at least from 2015 with HDMI 2.0 and HDCP 2.2 to pass 4K to the projector. You also need/want a UHD player like the Samsung 8500. So total project could be around $6000. If you go with a 1080p projector like the Sony HW45ES then total cost could be around $4000 including new receiver and screen.

Honestly If you only hear port chuffing on a scene or two with 1 port mode at your listening level, I would leave it at 14/hi, med or low (depends on if you can tell the difference). I have the feeling you won't like 2 ports but don't let me talk you out of it, try and hear for yourself.

Why not try them all. REW them and look at the graphs, get the feeling of each and see what you like the best. You have all the equipment and the time. MIght as well

As far as the projector vs receiver goes. You have to think about what you will use the most. a 9.2 receiver will not be cheap but neither will a projector/screen. I was looking at the Sony 45es myself and would have been roughly $3000 for projector and screen. In my room the size cannot get over 100" (fixed screen). Plus I am in a rental so I have decided to just buy a 65" 4k TV and pull it out from the wall a foot or more and just use that. I have been using a 55" TV for now and the speakers make the movie more than the screen size did. Now, I have never had a larger screen projector before so I cannot say anything about the experience but I would imagine that you get more of a theater feel with a bigger screen.

The size depends on the distance. My 110" diagonal has been fine for the last 14 years with the MLP located about 12 to 13 feet from the screen. I was one of the early adopters of those tiny DLP projectors that were made more for business presentations rather then HT & at $2K back then they were not cheap (around $4K in today's $2s). Sure it was noisey but my 7.1 system had no problem drowning the fan noise in most scenes. I recently upgraded all the inwall speakers to B&W inwalls (Two Signature 7's, four CWM7.5, four CCM65), the non-HDMI Yammy is being replaced with a "future-proof" 7.1.4 Yammy 3060, the projector is being replaced by a Sony HW45ES and the 240w/800w peak 15" Phase Tech Octave Sub's components were replaced with the Rythmik 15" Custom Installation components. The screen is changing from a Draper Targa non-acoustic to a Seymour AT UXD fabric but the one thing I am not changing is.... The SIZE of the projector screen because IMHO this 110" is PERFECT for my 18' (long) x 13'6" (wide) x 9' (tall) room.

Files attached. These are all without EQ or PEQ - 100Hz crossover. I think the Low 1 port option is still what I prefer, especially since I don't gain much at all with medium or high.

I'm going to run again now, after PEQ'ing the low, 1 port response.

A few people here recommended I do this. I don't think the sweeps will damage the sub. They are barely taxing it at all.

The Low and High look pretty good with 1 port. Two port you don't gain anything but you lose alot of extension.

Yep...
Sweeps will not hurt anything...its steady state tones that will toast a voice coil quick.

Here is the almost final graphs attached. I redid Ch4 so it x.over better with others. More of a flat response for now - until I rerun MCACC and then boost LFE. Will post that next

With Ch4 you dont get that spike at 100hz like you do with the other ones.

I'm going to run again now, after PEQ'ing the low, 1 port response.
For these types of graphs, 1/6 smoothing makes it easier to compare.

Yeah looks like 100hz gives me a real bad crossover dip and spike, so went back to 80hz. This is 1/6 smoothed, but it doesn't look half bad.



This is with the sub +3 from the -6 MCACC put it at. It's a nice 9-10db boost from 13hz-70hz.

Here is Channel 4 - LFE



Too bad I can't listen until tomorrow! Watched a couple episodes of Stranger Things with the wife earlier tonight, not a ton of bass, but there were some pretty cool parts where even at relatively lower volumes, (-20 from reference), we could feel the couch pulsing. Cool! OH I also forgot to mention I picked up a second pair of Polk T15s today for my rear surrounds. So now the front heights and rear surrounds are all the same Polk T15. Kind of a funny story. When I bought the first pair at best buy on 8/14, they were $69.99. Today I went to best buy to return a cord i didn't need (from same time I bought the first T15 pair), and the T15s today were $99 (even on Amazon!). So I went to do the return and purchase and the customer service guy noticed the price I paid for them on 8/14 from the receipt - and took $30 off for me on this pair! Anyways, thought I would share - first time I got lucky like that at Best Buy. $30 is $30...

Nice grab at best buy. Glad they can work with you on those speakers. $30 is a giant steak, so yeah $30 is $30 haha.

That graph looks a lot better. Let us know tomorrow how it sounds.

My F12 should be hitting Rythmik tomorrow sometime. Hoping for shiping early next week for the FV15 back to me.

Nice. Rythmik has been great about getting me both subs speedy. Are you waiting for them to process your return before buying the FV15HP?

Yeah, I dont have the funds to afford one outright without the return processed of my F12

Gotcha. My LV12R is also on the way back to them now. Excited for you to get the FV15!

Plugged in my JBL $300 sub and it was such an awful idea. Was almost better not having it plugged in at all. I had missed my F12 at that point but I am excited for what the FV15 has to offer.

Check out a Dalite Deluxe Model B 106" 16:9 screen.
Manual pull-down, and includes a tensioning arm to keep it flat.
$300 in 1.0-1.5 gain, depending on projector brightness and seating angle.

Although a little smaller than ideal, this kind of setup might be an easier fit for the room.
Then, when you move to the basement, you can switch to a bigger & nicer fixed frame screen.
106" is still better than a 60" by miles and miles.

This is helpful for determining screen gain:

If it were me, I'd get a projector before the Atmos receiver. Atmos is cool, but the projector will make a much bigger difference.
