I use BJC LC-1 subwoofer cable between my Denon 3310 and F12SE. No hum or noise of any type in sub. Eerily quiet.

I realize there are advantages to having multiple subwoofers , but I can afford only 1 at this time. Should I purchase 1 F15 and maybe add another one later, or would 1 F15HP be enough to satisfy my requirments?

A couple of questions for Rythmik owners.
I'm in the "choosing gear" stages of a ht + play room build. I was recently auditioning the aperion verus grand speakers and I had brought my wife along. During the audition we determined that she pretty much preferred movies with the subwoofer turned off completely. I obviously scrambled to try to figure out how I could avoid having to turn off the subwoofer for 75% of the movies I watch. After some research I decided that maybe the best way to accomplish this would be a pair of sealed rythmik subs. All the things I've read about these subs make me think that they would go a long way towards removing any booming or rumbling and my wife might not object to having them turned on at full volume. Does this seem reasonable?
The second question is whether dual f12 or dual e15 would be better for a room which is just under 5,000 ft^3, given that I listen at pretty moderate volumes, probably -10 at the loudest. I saw a post someplace with estimates of the relative db differences between all the various rythmik models, I was going to try to use that to inform my decision making but I can't for the life of me find that post anymore.
Thanks in advance.

One sub and two amplifiers . I have the A370PEQ amp Is it safe to connect one amp (Tube) via speaker Level inputs and the second amp (solid state) via RCA to the Left and Right inputs ? What happens if BOTH amplifiers are turned ON ?

Rythmik Brian,
Question though, clearly my FV15HP is a big step up from my previous sub so I am rightfully blown away. I understand it may be a little political and such so I won't name names but... Considering only ID subs that cost more than the FV15HP and/or F15HP without a servo design (hmmm, wonder which few I have in mind here), can they keep up in the accuracy department or are they just more blunt LOUD and DEEP??? No worries if you don't want to comment, I understand, but I have not heard the others and being very pleased with this, I do wonder. Comments from all are welcome of course, hopefully some of you all have heard these and the others.

Then read some more and think it all through again, trying to decide which Rythmik(s) to get. I went from bottom (12" driver and 370W amp) to top (15" and 600W), excluding the FV series. And even to the Rythmik driver and amp in the Salk enclosure. But last night I read a post somewhere from a DIY guy who said something to the effect "I am sold on the GR/Rythmik sound". It was only then that I realized I had not even considered the F12GR. I can guess that a lot of you chose the aluminum driver because your audio system does double duty for music and home theatre, but what's my excuse? Maybe because the aluminum looks hi-tech (the 1501, 1505, and 1510 look SO cool!) while the paper GR seems kinda pedestrian (no offense, Danny!). Or is it because I bought into the notion that sound output is the most important criteria for judging the desirability of a sub, rather than sound quality? It was SQ that attracted me to Rythmik in the first place, but, taking it for granted in a Rythmik sub, I had forgotten about it in my subsequent thinking. My need for a sub is predicated on the fact that my two sets of stereo speakers (one a mini-monitor with a 4 1/2"---ha!---"woofer" driven by a 25/25W stereo Class A SS amp---though they are about to be replaced by a two-way with a 6 1/2, the other the old Quad ESL's driven by a pair of 60w mono Class A OTL tube amps) need not just a subwoofer, but also a woofer (crossed over at 80hz). A woofer that can match their extreme transparency and ability to unravel the densely threaded musical fabric of the music I listen to (Baroque in Classical, with it's counterpoint between harpsichord and strings, and Bluegrass in Pop, with it's close-harmony vocals and acoustic instruments) in my sealed 10(H) X 13 X 19 room. Sure, I listen to AC/DC cranked sometimes, but 95% of the time it's acoustic music at moderate volume. Seeing as how the lowest note in a lot of acoustic music is that of the upright or electric bass playing the open E string at 42hz (though a grand piano goes deeper than that, at what level?), I'm not really in need of extreme output at super-low frequencies, except for the occasional pipe organ recording. So, to those who know about both the GR and aluminum Rythmik 12" drivers, what does each offer in contrast to the other in the reproduction of music? I would love to hear from Brian and Danny!

We extend the 10% multiple sub discount to single F12 black oak finish so that we can get more space for the new container arrival on July 23.
In the new container, we will have more F12 black matte, piano black finish, more F15/F15HP black matte/black oak, and more DS1510 drivers to fulfill a lot more HP subs. The factory also in the process of moving A370/H600 XLR2/3. The early air ship batch will arrive July 17 with the rest ocean freight to Austin before end of August. We also push forward HX800XLR3 production and hopefully we can get it done with 6 weeks.

From what I’ve read the F12G is a little smoother if that’s possible and will cross a little higher than the F12. From what you’ve described I think either will work great. As to which would be the best for you there’s no way to know, the difference between the two is so small just pick one and don’t look back.

I know the FV12 is currently out of stock so I'm waiting for you to get more in order to add another to my theatre room but thought about taking advantage of the discount on the F12 (which I might use somewhere else once I replace it with another FV12). By the way, I've had my FV12 for about 17 months and love it. Even after moving to a new home with a much bigger theatre room, it has handled it great (one is never enough though ).

you dont want to do that because the phase difference between a sealed sub and a ported sub can be very different. For instance, a sealed sub at 20hz can have as little as 90 degrees phase shift (or group delay) while a ported sub with rumble filter turn on will have close to 270 degrees phase shift. If you can find the group delay of each sub, you know exactly the phase difference and can add rumble filter (which is HPF) to compensate. But that is a lot of research. If you don't have those plots, it will be a lot of trial and error.
