The JB (JohnBlue) Super Tweeter is a miniature high frequency driver housed in a custom casing, designed to be positioned on top of, and drawing its input signal from existing speakers. It will transform any sound system setup and enhances the overall sonic quality and frequency of the speakers that it is paired with.

All models are stand-alone units with toggle ON/OFF user selectable options to ensure perfect synergy with the speakers to be paired, Each JB Super tweeter has 3 sets of switches to fine tune the operating frequency bands and output level, providing maximum flexibility to match ALL Speaker types for a immediate, direct upgrade of acoustic performance.


The Super tweeter comes with specific crossover and frequency control settings, with the frequency cut off points at 14 kHz and 17 kHz. Depending on the genre of music and type of speakers, the 3 sets of switches can be toggled ON and OFF in a myriad of 8 different combinations (2 at 14 kHz and 6 at 17 kHz). Each combination produces different SPL and High frequency volume.

Combination

1: when ALL 3 switches Toggled ON, the frequency cut off will be lower but High frequency volume and SPL will be at its highest.

2: when ALL 3 switches Toggled OFF, the frequency cut off will be higher but High frequency volume and SPL will be at its lowest.





Unlike conventional super tweeters, the JB super tweeter does not use VR for controlling output volume to minimize distortion and coloration. Instead, like the famed Tannoy ST-200 Super tweeter, a proprietary crossover network is selected for the SPL output control, each pair of Super tweeter is precision matched to ensure all output SPL and high frequency volume of are balanced.

Key Features:

Internally wired with High Purity copper/Neodymium magnet system
Further extends frequency response
Reduce eddy current losses within voice coil

Hard Anodized Aluminum sphere to eliminate diffraction from housing coupled with a Copper induction core ring with spiral winding for enhanced output power minimal signal loss and maximum frequency extension.

Gold plated connectors and omitting VR for controlling output volume ensures optimal signal transparency and coherency . Specially designed to augment high resolution signal sources such as SACD/DVDA allowing speakers paired with to realistically reproduce the entire spectrum of the extended frequency bandwidth

"Music" as opposed to sound, consists of transient, albeit micro details and rich harmonics that are beyond human hearing range for pure tones. Bass notes, for instance, contain leading edge transients nearing 30 kHz. The JB Super tweeter comes into the picture between the roll-off point of the high frequency unit of one’s existing loudspeakers and 43 kHz, with pinpoint accurate reproduction of the leading edge of individual notes, enabling the listener to be enveloped by the entire bandwidth information of instruments.

The JB Super Tweeter is designed to extend the frequency response by two octaves to aid correcting time and phase response within the bandwidth of normal human hearing. When operating beyond the range of human hearing adds, the net effect is a realistic soundstage as a result of improved imaging and instrument location.

The JB super Tweeter brings forth a 3dimensional soundstage, space, timing and accuracy– making reproduced music, as it was intended and recorded.
