Just a random happy customer check-in:

I've had my FV18 for a little over a year now and I'm still in awe at the performance and build quality. I have a very difficult room, open at >8,000 cubic feet; at the same time, I have limited placement options. Despite the room volume, I run 12 Hz tune with high damping and rumble filter off. This sub sounds so great with music, tuneful, and no overhang. With movies, this thing can shake me on the couch. Other than the ridiculous size, this is simply a fantastic product at a very reasonable price.

I cannot recommend Rythmik enough.

hi all

have a few qs about my fairly recently acquired Rythmik LV12R sub which i was hoping y'all could help me with.

1) played "war of the worlds" scene (where the aliens come out of the ground) to try out the sub & saw the led light at the back of the Rythmik LV12R subwoofer blinking few times. the subwoofer gain was at 5 notches above 12 o'clock (approx 1 o'clock) & the avr's volume at around 14 (have run audyssey with the sub at 12 o'clock which returned a trim for the sub of -5). playing around with the gain and avr volume find that the blinking in that scene starts occuring at about 3 notches above 12 o'clock & avr volume at 15+. if i turned down the gain/avr volume a little then it only blinked once (when the first ray is shot). I've read here that it's a sign of the limiter kicking in, but what does that mean? that the sub could get damaged? should i turn down the gain? what are the possible effects of keeping the gain at such a level that it clips occasionally as such demanding scenes are few.

2) in my setup i found that there's a big difference in the sub being at 12 o'clock where it sounds ok but like a regular sub & at say 2 o'clock where you really feel & enjoy it. is that ok or indicative of any issue? would it be ok to keep it at 2 o'clock if there is no audible distortion?

3) is it ok to flip the Bass extension switch/LPF slope setting while the sub is on & media is playing?

4) sometimes when i skip scenes in a movie there is a slight pop sound from the sub. i also have a klipsch rw12 sub connected & there is no such pop from it. what could that be due to?

5) in one of the pleasant (& unexpected) effects of having the LV12 - the aforementioned klipsch sub before the rythmik came in would rumble & make some creaking sounds in demanding scenes but now when i have both the subs on the klipsch has stopped making those noises. how does the rythmik stop another sub from doing that?

6) is it better to run audyssey with just the LV12R running or both subs on?

7) if i read the quick guide right, for movies Bass extension switch should be LOW & LPF to 12db & for music it should be HIGH-24db? so for what media should the Bass extension switch be on MID?

TIA

Searching for "electronic crossovers" I ran across some interesting units:

https://smile.amazon.com/Planet-Audi.../dp/B002QUZHY6
https://smile.amazon.com/Sound-Storm.../dp/B001TE5YWU

Designed for car audio, but I don't see why they wouldn't work at the PC if you figure out how to power them. Thoughts? Maybe there is something more turn-key, but I'm still looking.

There is something to be said about the flatter response of the ported sub, where output is maintained until a certain point where it drops off - unlike sealed, which has a rounder-looking graph. A flat response is generally desired in loudspeakers, where you can say nearly all frequencies are reproduced at the same level. You can achieve this flatness with sealed with the reinforcement of a small room, but not in a medium to large room. Several have said that the sealed subs have a slight advantage in tightness, where going from a ported Rythmik on high damping to a sealed Rythmik is like going to "super high" damping. Brian at Rythmik attributes this mostly to differences in impulse response. This has me torn between an upgrade to a sealed or ported 15" pair. I can see either being awesome for my application. The thing about sealed though, is I'm nearly certain I would want double the drivers. So it would be between 2xF25 or 2xFVX15 - both achieve the same 20Hz output, but it's hard to ignore the fact that the ported pair does it for $1,100 less.
Yeah, since my listening is biased so much toward music, that suggests sealed BUT the servo tech suggests that you can have your cake and eat it too with a ported Rythmik. But Rythmik's own website suggests sealed subs for music, BUT the kind of music I (often but not always) listen to (hip-hop, etc) traditionally pairs well with ported designs. In fact I often listen to music on low damping on my LV12R. It's enough to make your head spin!

Ultimately, since I've enjoyed the LV12R so much, I'm definitely not opposed to another ported sub (the FV15HP really seems like a great value at $1300+). I wonder if there's any advantage one way or the other between ported and sealed in a single-sub setup.

As for the 2xF25 vs 2xFVX15 comparison, I feel like four drivers MUST be noticeably more beefy than two. Whether it's $1100 worth of extra beef....I guess that's the real question.

The extra beefiness (is that a word?) would be apparent in the midbass area. After 40hz or so the F25 pair would have more output than the FVX25 pair.


If you like the sound of ported, and you think the FVX15 pair would have enough midbass for you, then I don't see a need to spend the extra $.

How does the piano black finish on Rythmik subs differ from the standard vinyl wraps? Is it still vinyl? Or is it a wood veneer with with paint applied?

The piano black finish is "body shop" kinda paint finish. Same for the black matte paint finish available on the FV18 and FV25HP.

Thanks. So what is the material directly below the paint. Is it just the MDF? Or is it a wood veneer?

Great to hear, I am in the process of saving to get two of them.
And my room is only around 1728^ft, these FV18 should make wonder in my room

So after lots of testing, I still haven't filled my nulls. So fortunately I'll be getting another fv25hp to fill in the nulls my space is less then 800 sqft and somehow 1 is not enough for me. 2 should fix my nulls and OCD with my right side being different from my left. Can never have too much bass, that's my problem

It’s available in black oak though not in piano black. The black oak is really pretty though.

Plus your new FV18 will have the larger ports.

Imagine you are standing outside the room and:

Length: Looking at the room from its longest side
Width: Looking at the room from its shortest side
Height: Tilting your head and looking at this graph vertically, floor to ceiling

This gives you an idea where not to place your head when listening. Picture your equipment and furniture in the room. Adjust accordingly, within space/wife limitations. Also, multiple bass sources will counter some of these modes with intelligent placement.

wowww! I mean I won't lie I had to read it about 10 times in order for me to understand it. (Little slow I am) THANK YOU!!! Because of my only sitting area I'm pretty sure I have it in the wrong space/ wife limitation

Okay. Thanks. I guess I was just a little confused when reading Jim’s review of the G25HP, where he said there were finish options in, “...black oak veneer, matte black vinyl and a high gloss 'piano' finish.” I understood what he was talking about with the black matte vinyl finish, where it is just vinyl applied directly to the MDF. But, I was assuming that the other two finishes where veneer’s with either a high gloss paint applied for piano black or a stain for the black oak. I’m only asking, since I have very little understanding of woodworking. I didn’t know that MDF could be sanded very smooth and painted directly.

I forgot about this Harman mode calculator. Thanks for posting this. I now found my 40hz null issue after plugging in my room to the calculator. My MLP is centered at 7’ in a 14’ wide room.

I’m gonna try a couple different placements when time allows(my better half told me front wall placement was the only option due to it looking best, that was a prerequisite to getting a second one lol). I’ve also played with it on the room simulator in REW and the null is pretty much there regardless of sub placement. If I move my MLP to the left 1ft it looks like it might help a lot.

Took me a minute to figure out what I was looking at, but what a great tool!

I second that, it is quite similar to the oak veneer SVS uses on their Ultra speakers but the finish on my FV18 is slightly smoother to the touch. It is beautiful.

The FV18 is available in black oak and black matte paint finish. The black matte paint finish is beautiful. It's the same finish of the FV25HP.

MDF is actually the most common cabinet material for speakers and subwoofers. It's compatible with a wide variety of finishes, including paint, and is rather inert so it makes a good choice for speakers and subwoofers. When you think about the fact it's essentially sawdust and glue fused together with heat and pressure it does make you wonder about some of its properties, but the stuff seems to work well.

If you take yourself too seriously expect me to do the exact opposite...

It's not the best, but it's good, though heavy.

On finishes, here's an idea: a clear coat over the black oak would look sweet. Shouldn't be any more work than the black paint.

Good grief, that should do some damage. Do you have enough room? Even though I made up a template, I was still unprepared for how large this thing is.

Thanks for confirming, I was chasing a ghost
More likely will be getting the Black Matte finish, when I order.

Plus your new FV18 will have the larger ports.

I've been lurking on here off and on for well over a year trying to figure out what brands and types of equipment I'm going to buy when I finally get to the
point where I feel like I have a handle on the latest in audio/HT. I see a lot of great info on here and have learned a lot, but by no means have learned nearly
enough. I have no clue when it comes to room correction software/EQ stuff I see people mentioning. It overwhelms me and I'm going to wait until I get some
sort of start in buying equipment. I have budgeted for a system that will be geared for music as the priority for picking components but will also double as
some sort of surround/HT setup. (not sure about Atmos - most likely just a 7.2 or even 5.2 to get started) I'm looking at powering the front 3 with a dedicated
power amp and the rest with an Anthem or Marantz. But as I said, that's going to be after I get my feet wet with subwoofers, which is what brought me to post
on this thread. For a year I've been looking at SVS, PSA, and Seaton mostly, until recently when I started to really look into Rythmik. For my main system I'll
absolutely for sure be getting two sealed subs and I've really come to like what I see and read about the G25HP. Two months ago I was pretty much settled on
2 PSA S3010's but have since been sidetracked with Rythmik. With all that being said as a way to introduce my intentions and where I plan to go with my posting
here, I would like to ask a few simple questions that I don't want to get sidetracked on, initially. Later I'll welcome sidetracking, but for now I'd like to be
able to put Rythmik in some sort of perspective in regards to what I can expect as far as decibels and impact go. I have no means to listen to a Rythmik sub
without ordering one and trying it and I realize I could do that but I thought I'd try to get some insight on here by asking for opinions of people who may have
experienced both of the subs I want to know about. I don't want to know about quality of the sound or which is more accurate or anything like that (I already
have an idea which is the winner there) all I wanna know is how an F12 compares to a SB3000 in terms of slam, impact or decibel level for music? I know there's
much more to judging a sub than simply looking at its amp power but in this case the F12 is powered by a class A/B 370 watt amp and the SVS is powered by
an 800 watt class D amp with claims of 2500+peak. I don't see any peak power specs on the Rythmik site. The reason I'm asking about these two subs are that
I've recently had the opportunity to hear an SVS SB3000 and thought it was impressive considering the size and price. Can I expect the same from the F12 if I
were to order one to pair with a simple soundbar setup just to get my feet wet and start messing with some audio equipment, rather than just reading about
it all the time. As I said, I only want to know about how hard it will hit compared to the SVS with say rock music that's loaded with double kick drum sequences.
I've all but decided to go with Rythmik but don't want to be disappointed with how hard it can hit, because I'm already assuming it's extremely accurate and
sounds great, but will it slam as hard as the SB3000 is my question. Rythmik uses class D higher power for the G25HP (which is highest on my list of subs for
main system I'm starting soon) yet a lessor power class A/B for this F12 and it concerns me in regards to shear output abilities.

Thanks, Brian.
In terms of output, the real competition for the SB3000 would be the L22, not the F12. The L22 would have more output and lower extension than the SB3000 at a lower price.

I sure do now

Since my back row in my Theater is never use, I got rid of the riser and the couch
Will more likely move the front row back a 1 foot or so, to find the sweet spot.
By removing that row, I got plenty of plenty of space to play with now

For the damage, I am not a Bass head. Just love nice clean sound, and more likely be set at +2 dB after calibration.
I always like the idea of template, but do use a measuring tape. And measure, measure often
That said, I did built a template made of wood. For my front speakers (after I found the perfect angle), do the front left first.
Reverse the template for the right one, and both speakers are at the perfect angle and geometry from side/back distances. From the sides and back wall.

I’ve also played with it on the room simulator in REW and the null is pretty much there regardless of sub placement. If I move my MLP to the left 1ft it looks like it might help a lot.

Took me a minute to figure out what I was looking at, but what a great tool!

Indeed a great tool, just need to find a link to add for my favourites.

Sitting in the center of a room length wise, is always the worst spot when it come to Bass.
That said, while I was also trying to find-out if it was also true for the width of a room.
You have provided me, with an answer

Height: Tilting your head and looking at this graph vertically, floor to ceiling

This gives you an idea where not to place your head when listening. Picture your equipment and furniture in the room. Adjust accordingly, within space/wife limitations. Also, multiple bass sources will counter some of these modes with intelligent placement.

While I do some key words to find the "Harman mode calculator".
Do you have a direct link to provide me, in case I cannot find-it?
