I've only had it a few weeks but it does everything I wanted. It plays LOW and has that body jarring impact that I've envied in other's folks ported subs (but it's so CLEAN!!)
I originally planned on using it with my sealed 15" Titanic kit sub from Parts Express but I'm getting a better sound with it alone. The Audyssey XT32 on this receiver tried it's best to pull both of them in but I just didn't feel like it was any better.
Maybe if I got off my butt and tried more placement options it would work but I don't feel like there are any huge nulls or bumps as-is.
Anyway, great service, excellent packing, terrific sub!! I can't imagine having two of these things.

Well I hope someone see's to it that Brian addresses this post! Yeah Brian I want a larger driver, will you please do your magic and do it. I to was considering another F25,newer 800 watt version using two 1510 drivers,I called Brian and e- mailed him to talk but no answer. Spoke with Enrico but he suggested I'd speak with Brian. Brian did leave me a message on my cell about "b"stock which had nothing to do with my call, don't know how that got into the conversation . I haven't heard back from Brian since my last e-mail. Wish I Would! So presently I am considering Si 18" drivers .
For those wanting a Rythmik 18" sub, you have to keep in mind.....those 18" subs are just an 18" high excursion/output driver in a DIY cabinet (usually, although Funk up in Canada offers complete 18" subs), with a Pro Audio amplifier (Ahem. Pro Audio amplifiers are NOT designed for Audiophiles) and separate cross-over chosen by the end user. In other words, the sub buyer is actually the designer, to an extent, of the subwoofer system.
I think Jeff Permanian (JTR) would disagree with you. There's nothing DIY about his stuff.
The most difficult part of ordering from my suppliers is to get the correct mix of black oak and black matte. For instance, I had more black matte than black oak in the inventory for F15HP and E15 (although they started with equal mix), and therefore I anticipated I should have less black matte to start with for LV12R. It turns out I am wrong again.

LMS ultra is a very good driver. A customer loaned me one. I set up my non-servo amplifier with LT EQ circuit to make sure the close-mic response is same as my servo sub and them compare. LMS ultra is smooth and can play loud. On the other hand, there is some extra detail from our servo subs giving the sense of intimacy. I am pretty sure most customers may not be able to hear the difference and others may even like LMS and thought it is "cleaner". It all broils down to what is the important aspect of sound to anyone. If detail and intimacy are the most important aspects, then our servo subs can provide that advantage.
This is related to another subject. A potential customer called me the other day asking me why we don't have a lot of ads like SVS. I explained as soon as you have an ad like that, it opens to all types of customers, some of them like it loud and punchy, and some like it aritculate and others like the bass boomy..etc. How can a company make a single sub to fit all these needs? Eventually that changes the direction how a company designs their subs to suit customers' preference. We, on the other hand, like to sell our subs to the right customers, in particular those who can appreciate the type of sound quality our subs provide and chmccorkle's feedback just made my day. BTW, there is another analogy out there that is so obvious to anyone --- Lemonade. We are so used to the artificial lemonade that the real lemonade becomes tasteless in comparision. Even those claim to use real lemon have to add artificial flavor to make them "tasty".

I can't wait for the below! Not sure why since I already have two LV12's.
Per Rythmik website:
We are phasing out FV15 and replace it with a slightly smaller dual-port multi-tuned sub with 12" aluminum cone driver. It will be available in the summer.
Brian if your out there any updates on the above?
It will be delay untill some time towards end of this year. I do put this model at a higher priority than the entry level sealed sub.
Does anyone here know who has the most number of Rythmik subs ?
I bet 4 or 6 F15HP would be wicked !!!
I don't need much to push me to buy the Rythmik DIY DS1510 subs as every review mentions Rythmik's sound great and it would definitely be cheaper for me. I'm not a bass head but want to buy a sub system once that will last for 10+ years. I want decently loud with solid 10-15 hz output. Due to my small but open living room (http://www.avsforum.com/forum/newestpost/1481418), 3 subs as end tables would fit well. I like sealed but would consider the Rythmik ported since it is said to have clean, almost sealed sound. The problem I have is that while people have multiple Submersives or this or that, few users seem to give reviews of multiple Rythmik subs. So while I have confidence that a Submersive or LMS 5400 could do the job, I'm not sure the same of a Rythmik. And while I think the FV15HP would get deep, there have been some reports of port noise when in one port mode. And since I really haven't seen enough comparisons of the F15HP, I'm not sure if 3 would be loud at 10-15 hz. So even though I'd like to go for Rythmiks, there is doubt that I don't have with the LMS 5400 or Submersive.
Brian have you given any thought to adding an 18" servo driver to your line-up? I bet you'd sell many, also in a ci version would really do well with DIY 'ers. There is a large buyers interest on this forum else where. Please answer this ! These days I want to add18'' drivers to my setup, I have two f25 kits 600 watt amps and two f15 370 watts PEQ 2. I'm thinking of getting a couple of 18" subs from Si and was hoping you will consider doing 18" direct servo Rythmik subs. Just my personal idea, no offense intended. I love Rythmik products .
This is a picture of my front setup before i changed the rooms look chairs and room panels are now changed, however the front did not change. Two f25 600 watt version,diy cabinets on the left and right side of my Jtr T12 center.
Rooms new look, front is still the same in this picture with grills on L&R and cabinet with the center ch and two horizontal placed f25 subs.You can see how the room has a different look.
Here you can see my rear two f15's.
Old look with the new chairs
These pictures don't show my counter with two leather stools at the rear.Need to take some.

Will it be released by the end of this year or it will be announced what it is at the end of the year ?
Also will it be available in Piano Black ?

You may not realize that "decently loud" 10-15hz output is not what you expect. I have at least two customers thought there are something wrong with the FV15HP they purchased because they expected 20hz output to be very "loud". One of them is in Alabama and he had his friends brought in an eD sub of 12" and another sub of a different brand I don't remember with 10" and he told me both are "louder" than FV15HP. Since it is too far away for me to pay a visit, I sent him a CD with warble tone, another CD with pure sine waves, and an SPL meter. I told the customer pay attention to the reading from SPL meter. He didn't have time to do the SPL measurement and meanwhile he spent about a bit over 1 month listening to our sub. When we finally were able to do the SPL reading, he already have enough miles with our sub and he noticed the sound coming FV15HP is closer to what he heard from Imax theater and the SPL meter reads ok with 20hz warble tone. He was just not ready to accept the fact that 20hz can be so inaudible and hence something is wrong with the sub. But as soon as we switch to 30hz and 40hz (with the same SPL level), he can tell the sub is very loud. The same thing happened to another local customer with similar story. So if clean 20hz is close to "inaudible", you can imagine what 15hz would be like or even 10hz would be like. Then the question is why do we even want to waste power amp energy on inaudible signal tone? My own answer is phase response. Lower phase shift gives you more natural replication of the input signal. But that does not mean the input signal should contain a lot of content in that frequency band. For instance, "How to train your dragon" is known to have good 10hz content and below. Does that make it more enjoyable than say U571 (which has much less sub 15hz content) other than it can trigger DC protection of older design subs? In other words, what made the sound engineer of HTTYD decide to keep so much "inaudible" subsonic contents (instead of using a subsonic filter to filter the content out). So this broils down the question is how loud do we really need 10-15hz output. If we don't, why do our sealed subs like to claim extension down to 14hz? I am repeating the question again. But I really want the customers to understand it is because 14hz extension means lower phase shift in the passband and therefore give you better sound reproduction with more palpable sound stage and other nuisance. We sent our subs to Ricci and others to test because we want to show there is no compromise in SPL output by doing all our fancy servo designs, not because we want to win the contest of SPL competition. In short, the sound engineer of HTTYD leave the subsonic in due to a mistake, not as a feature to make the movie more enjoyable.
BTW, the port noise issue warrants more discussion. It is definitely audible during test because the subs are intentionally driven into overload. In addition, we have different damping setting. We have also recommended in HT use with 1port, set the extension to 14hz "low" damping. This will limit the port output below tuning frequency and hence port noise. For music, we recommend 14hz "high" damping. This mode has a more gradual phase shift, but it can expose the port noise. In our FV15HP spec page, we have shown the response of 1 port and 2 port modes with same 14hz low damping setting is almost identical above 20hz. But Ricci didn't get the same result. So I really think he had damping mode mixed during his tests. Other typo in his test includes the port diameter. Our port is 3-1/2", not 3".
