Product Description

The Subwoofer for Audiophiles

For audiophiles looking for uncompromising accuracy, Rythmik Audio F12 12 inch Sealed Audiophile home Subwoofer is the ultimate choice. It features our Direct Servo technology to ensure accuracy and definition. As an audiophile you appreciate that bass is the foundation of a satisfying music or home theatre experience. You also appreciate that there is more to a home theatre subwoofer than shaking the room, and that music can be far more satisfying with a subwoofer that can play deep.

What makes our subwoofers suitable for audiophiles? It’s not that they can plumb the depths with authority. There are already many subwoofers on the market which can do that. The difference is that they reproduce bass with a level of realism that is normally only associated with much more expensive high end full range loudspeakers.

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.

All our subwoofers use our patented Direct Servo technology. The most significant benefit is that it provides high end performance at an affordable price. Conventional subwoofers require heavy drivers in order to achieve deep bass extension. Direct Servo allows the use of a lighter driver which is more efficient so that a very high powered amplifier is not necessary. At the same time, Direct Servo reduces detrimental memory effects which detracts from the realism of reproduction.

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
  • The effective Q value is 0.3 resulting in much tighter and accurate bass than conventional designs
  • Dramatic reduction of the re-radiation of bass from inside the box

Many audiophiles aren’t aware of all of these issues, but we believe they are critical to the design of an accurate subwoofer. While it’s not necessary to understand them to enjoy accurate bass, for those who wish to understand how we do it, we have articles to describe our unique approach.

Better value through intelligent design

Many of our customers marvel that we are able to produce such exceptional subwoofers at such a low price. One Direct Servo technology makes it possible, allowing us to get the most out of a 12″ driver without the need for kilowatts of power. Don’t be fooled into thinking that other more expensive subwoofers with much more powerful amplifiers will offer more output. The output of a subwoofer is determined by how much air the driver can displace, not the power rating of the amplifier. We could supply a more powerful amplifier, but there would be no increase in output, only extra cost.

The standard amplifier is A370XLR3. (370WRMS with both RCA and XLR inputs). The quickguide of the A370XLR3 amplifier for sealed subs can be found here . A370XLR3 amps do not have high pass filter RCA outputs. But it does have dedicated LFE inputs allowing for easy integration of a 2-ch-plus-HT system setup. A370PEQ amplifiers are available for those who still need high pass filter (or HPF) RCA outputs. The quickguide of PEQ amplifier for sealed subs can be found here. Please order this amplifier as an option in the table below. The response curves with various extension frequency/damping combinations of both amplifiers can be found in our EQ page. Please select A370PEQ (manual), A370PEQ3 (manual), A370XLR2 (manual), or A370XLR3 (manual).
