I'd rather Rythmik (Brian) was busy making subs than spending extra time on AVS but whatever... R&D always takes longer than planned. The R&D mantra I have heard over decades of doing it: "Price, performance, schedule -- pick two, settle for one."

For you guys salivating for an 18" Rythmik sub, in spite of the "sexiness" of such a monster sub, the final price for it, with the considerable cost of shipping it to you, may well be more than the price of a pair of FV15HP's, or three or four smaller Rythmiks. And I have no doubt that three or four (perhaps even just two) smaller Rythmiks will provide better overall sound than a single 18. Something to keep in mind. Now, for you guys who can buy two, three, or four 18's, Hell yeah!

If I read the amp model number right, 2000W for a dual ported 15" fv25hp will be awesome. Easily +6db over the almighty FV15hp across the entire frequency range. I am a lot more excited for the FV25 than the FV18.

Pretty much!!. These projects is no joke and isn't a simple upgrade like they do with cell phones. There is no solid ETA so people should just be patient and wait. the Rythmik team is kind forced to give a date and when that date passes it's the same question again and again because of that. If anyone is worried about spending big cash then more waiting would be smart.

Thanks Enrico...much appreciated. That satisfies my curiosity.

Yes, between 1800W and 2000W. The FV25HP is +9dB over the FV15HP, mostly below 20Hz.

I don't think so. Brian has to come up with a competitive price with other 18" ported sub available from other ID companies which range from $1300-$1900.

I'd like to add that moving a huge 100 lb or more sub isn't easy either. My 60lb LV12R (70lbs in box) is heavy enough and has a pretty big enclosure for a 12" ported sub (all the other 12" ported subs I've seen are a lot smaller, especially the BB retail types). Even the compact F12 is about 90 lbs if I'm not mistaken.

Thanks, I must have been thinking about something else... though I do wonder how heavy the dual 15 ported and single 18 ported will be.

Hmmm lets see, F25: Shipping Weight 170lbs(No palette), (220lbs with palette)

IF ratios are similar to the 15" models below, then the dual ported 15 might be in the ballpark of 180lbs to 234lbs with/without palette. Also possible that it requires a greater increase in bracing and pushes up the weight even more and my totally wild guess is too light...

F15HP: Shipping Weight 108lbs vs FV15HP: Shipping Weight 115lbs = weight ratio 1:1.06

No guess on the 18"

So I have gone through most of the posts of this thread, read tons of reviews, opinions, graphs, etc. and now I would like to pose the question directly to you owners.

HOW GOOD IS THE F12?

Have you had the chance of comparing it to JL e112? What are your opinions? What made you chose the Rythmik over other brands you were considering?

I am about to buy two F12 to replace my RELs R528, which I did not appreciate as much as reviewers did.

I will be using the two subs placed close to my main speakers (PRO AC 140MkII) especially for music (70% of the time).

Any opinion / suggestion will be very much appreciated as you will be responsible for making me the first to import them into Italy.

Hey guys, we got yesterday the DS1820 driver cast aluminum basket and it looks Awesome!! Like I said, we are just waiting for the driver coils to arrive to start assembling of the DS1820 driver and of course, start production of the FV18. Here some pictures for you to enjoy



Did you notice this small detail? Yes guys, Rythmik LOGO printed on the driver surround

Wow, that would make it weigh as much as or more than me. I assume special considerations would have to be taken when moving it around the room to determine optimal placement. And 2 very strong people.

Though I am still in the crowd that would consider multiple 12 inch subs before a single dual 15 or single 18.

(Even a single 15 would be twice as heavy as my LV12R.)

Though I wonder if those interested in such 'super' subs are in it for output or extension mainly...

*referring to ported subs only

If at some point, this trickles down to the 12 inch drivers, including paper, it would be a nice touch. Having a few subtle Rythmik logos would be a welcome addition.

Does that come in a P215/60R16? Would make a snazzy wheel.

The F12 is outstanding but be sure you are not overestimating what the (any) sub does. Room placement and integration is very important. You might want to move your REL's around a little before giving up n them. As for the F12, I compared mine to a JL113 (among other subs) but only briefly and not in my system so really can't say how they compare. For commercial subs JL and Paradigm were on my short list but I think my F12 is comparable and in some ways better for a fraction of the cost.

+1, optimize your current setup before buying anything else... then upgrade if desired/needed.

LV12R and L12 will have the logo as well. As soon the inventory is gone, all new drivers will come with the logo printed on.

LV12R and L12 will have the logo as well. As soon the inventory is gone, all new drivers will come with the logo printed on.
nice

Thank you Don and Plasma for your suggestions. After playing around with my REL's for over 1 year what I was missing was extention and presence in the very low level frequncies. The Rel's have a steep roll off at 25 Hz and there is pratically nothing below 23 Hz.
As I do not like what room correction does to the sound, my goal was and still is to get the best integration possible without room correction.
Placing the RELs in a corner gave a nice boost at around 25 Hz, but could not get a good phase allignement. Moving them further out into the room got me a very good integration with my mains, but with a weeker low end.
With movies the REl's have a tendency to resonate at 25Hz (a kind of flapping noise from the passive woofer). We found this to be true with all Rel's R528 even at modest volumes (-26 from reference). Although not always very noticible, in some movie scenes (Intersteller is one example) this becomes quite annoying (to me anyway as others in the room seemed not to notice).
To me the Rel's are over estimated and would not suggest them. There are surely a lot more subs much more worthy and better built.

@ DON what do you mean by "be sure you are not overestimating what the (any) sub does" ?

I'm not Don, but I think he means that bass/modal frequencies are greatly affected by room acoustics and so getting placement, integration/phase alignment, (and usually some effective form of sub EQ) is just as important (if not more important) than the sub(s) themselves.

Same reason why you can often get better results with 2 or more smaller subs than a single huge one.

^^^ Close enough. The best sub on the planet poorly placed in a "bad" room with poor listening position is going to sound like a bad sub.

Sealed subs like the F12 are less likely to "flap" (no port, or passive port-equivalent, to "flap" and thus intrinsic response is more controlled) and the entire Rythmik line has a -3 dB point around 14 Hz or so. Rythmik also offers continuous phase adjustment to help you dial in the subs that will help immensely if you are not using any sort of room correction program. The servo control provides cleaner sound than many competing products.

Thanks to both of you. I know quite a lot about room placement, acoustics and psychoacustics so I do understand the interaction between the room and the loudspeakers. I had an NHT subone and it was great, but after over 10 years in operation it had some components on the outboard controller that started to have issues (mainly the volume control), so I changed it for what seemed to be a great option: the Rel R528. However, this sub is overpriced and build quality is very poor. Extension is not great either and control, as I wrote before, is sub par.
So I whant to be sure that Rythmik is not affected by any of the problems I had with the Rel's, which I have learnt from the distributor are often being sent back for repairs, but most of the time components are not available even for brand new models.
@Don your description of what the Rythmik does make it final for me to go for it and will be soon (end of July????) commenting my findings.

Thanks to everyone here that has answered my questions.

Man those little logos on the surround look awsome! I like to see a brand name on my gear but without it sticking out like a sore thumb. Very well done! Nice subtle and professinal looking!
