Rythmik subwoofers?


Hi all.
I have been looking for a small sealed subwoofer to add to my Harbeth P3ESR in a 20x15 size room. In my price range of about 5 to 6 hundred dollars and the usual suspects SVS,HSU,etc,etc. I came across this Rythmik sub. Anyone familiar with this brand. It is only sold direct. This is the model I have been looking at!
Thanks

Musical sub on a budget

Looking for an affordable musical that can be also used for moderate home theatre use? L12 uses our proprietary servo design to gain low frequency clarity and articulation. For home theatre use, L12 has a HT playback mode with rumble filter to limit less audible sub-sonic contents. While many of our competitors limit their best technology (such as servo) to their top level models, we wanted to make Direct Servo affordable, so we've held nothing back. As a result, you get the tight and music bass you wouldn't normally expect from a subwoofer at this price range. L12 is likely the least expensive servo subwoofer on the market.

Direct Servo Technology

You may have heard about other servo subwoofers which are generally well regarded for their accuracy. It is a well established technology, most often based around an accelerometer which measures cone movement. Our Direct Servo technology has significant advantages over other servo technologies. We use a sensing servo coil which acts like a microphone which compares the original signal to what the subwoofer is actually reproducing. The signal is then corrected instantly to compensate for any differences. Once you understand the concept, you may wonder like we do why anyone would make a subwoofer any other way.

Some of the benefits of Direct Servo include:

  • Reduction of the effects of thermal compression are eliminated under normal operation
  • Higher efficiency allowing output which would normally require a more powerful amplifier
  • Deep bass extension can be achieved using a low mass driver with superior transient response
  • Mechanical and thermal memory effects are reduced, further improving transient response
  • Much greater damping control over the cone
  • Dramatic reduction of the re-radiation of bass from inside the box

This budget level sub delivers the same articulate and tuneful bass that our subs are known for and yet provides enough HT bass thanks to its sealed design. The combination of servo and a sealed enclosure is what makes this sub deliver on both quality and quantity in bass.

I had a pair of f15 hp with my maggie 1.6s very musical and fast, i would buy them again.  Go for it you will not regret it. 
Rythmik are excellent subs, I use two F-12G in my two channel rig. So far very pleased with there performance.
Rythmic is overpriced had the F15 and another a 12 inch in a past life.. The best sub for music is the JBL LSR310s, buy them used and you can get it for around $250. The pro JBL sub got crazy resolution even in the deep bass.
I just had a conversation with Fritz, of Fritz speakers, looking for information on his floor standing models. After explaining my system, he recommended the Rythmic sub.A great guy to talk to. I call trying to buy his speakers and he is trying to tell me to try a sub woofer with my monitors and then goes on in detail on why the Rythmic is so good, wich is what that article says. Good luck, and if you do purchase one, I would love to hear your thoughts.
I built  2  12' down firing subs according to their plans, best I have heard
