Rythmik Audio FV15HP servo ported subwoofer : New [Expired]


no longer for sale

The unit is brand new. This subwoofer uses a patented servo feedback technology called direct-servo, meaning the sensor is just a sensing coil directly detects the cone velocity signal and then the servo signal goes back to the feedback network without any active device to ensure most prestine servo signal received by the power amplifier. This is contrasted with approaches from Velodyne and others which use piezo sensor. Piezo does not react to velocity directly. Instead it reacts to pressure. So there is a mechanical conversion process from velocity to pressure that can add coloration. And yet the signal coming out from piezo sensor is so weak that it needs opamps to amplify the signal before it can be used. The patented directservo technology addresses all these problems and the result is a very musical sound with articulation and clarity not heard at this price range. The amplifier is a class H amplifier and the driver cone is made of one piece dish aluminum. Subwoofer with similar cone sells at least twice as much. This subwoofer represents the best combination for HT subwoofer: servo technology on a ported sub. The amplifier also has a damping factor control to control the amount of ringing to each person's liking. Low damping gives more ringing and hence more full body bass sound and high damping gives the least amount of ringing and thence more agile and articulate bass sound. With one port plugged, the extension can go down to 12hz. The size of the subs is bit on the large size 18" wide, 24" deep and 24" tall. But large size enclosure improves efficiency tremendously. Sealed subs with 15% smaller in each dimension will need 4x the power to achieve the same output. The subwoofer has been selling for over 3 years and receiving consistently positive feedback.
