(Get the ultimate super low frequency regeneration without the need of any subwoofer but with a regular speaker)

This is one of our best seller and giant killer. It is not an old school equalizer but is an advance analog computer instead. The following equation is a simplified version of the internal programmed algorithm with pure analog computation process, absolutely no digital noise and no quantization error of any kind.

There are 3 control knobs in the front panel. The left most knob is the "Sub-woofer Size " (U1 of FUNC1) , which can virtually expand the diameter of your woofer from 6.5 to 10" and become 12" to 30".

The middle knob is "TONE or Richness " (U2 of FUNC2), which control the richness and texture of the low frequency.

The right most knob is "EFFECT" (U3) , which control both the effect of (Func1 + Func2) .

From the equation, when the"Sub-woofer size " set to minimum, then U1 = 0 and Func1 become zero and will be bypassed. When "TONE" set to minimum, then U2 = 0 and Func2 become zero and also will be bypassed. The "Effect" control how much Func1 + Func2 add to the original signal, when set to minimum any boost effect will be bypassed no matter what is U1 and U2.

An old school EQ will chop the input signal (Vin) into many section (if 10 bands then will chop into 10 separate sections) and combine them back at the output, which will destroy the original beauty and integrety of the input signal and ruin the sound stage and details as well as everything.

Instead, the output signal of our design is purely the input signal(Vin) + Func1+ Func2. The Vin has not been touched and is still ORGANIC. With this unit, your own speaker can output super low subsonic frequency without the needs of any subwoofer , you will always get the best sonic performance without the worry of matching subwoofer speed and placement . This unit already built-in "harmful subsonic" filter to cut off subsonic freq range that might hurt speaker drivers, it can make almost any 8"-10" woofer sound like a 15"- 30" woofer with even better solidity, control, punch, tenderness and elasticity, acoustic freq response can extend down to a new record of 10Hz.. With this crossover and a 80-100W solid-state power amp , almost any 8-10" woofer in a regular speaker with a ported cabinet can sound like a $10,000 active subwoofer. This model equipped with XLR and RCA inputs and outputs, and it can also serve as XLR to RCA or RCA to XLR converter. Use either RCA or XLR input, you can have true balanced output signal. Or use XLR input and convert down to RCA output with the balanced input performance.

You can just connect this unit between your CD and pre-amp , or between pre-amp to power amp, no extra power amp required and no extra subwoofer speaker needed, just use your own set of speaker systems and it will sound like you have added a super performance subwoofer. Many customer complaint they spent many thousands on their brand name audiophile system, but still can't get the real live performance effect . The major reason is live performance give out music with full range of spectrum (from 10Hz to 50Khz) , if your system can't regenerate truthfully in the very low frequency spectrum (10Hz to 50Hz range) , you will never get the real live performance feeling. Once added this unit into their system, every customers can easily get back the live performance sound stage response, much more musicality and openness. You will never get the same boost in peformance with the same amount of investment in any other products.

Mk2 Output stage use 2 x 6N1P ( alt : 6922, 6DJ8, ECC88, ECC188, ECC288, 6N2P, 6H30...etc)

Mk3 Output stage use 2 x 6SN7 ( alt : 6SL7, 6SU7, 5691, 5692, ECC32, ECC33, ECC35,CV181....etc)

The processing effect can vary from Bypass to the maximum with infinite step control , even in Bypass mode, the sonic performance will also be enhanced by the tube section , and give you a smooth , sweet and airy organic tube sound.

(Optional : 0 /180 deg output phase selector to match different pre-amp and power amplifiers. + $150)

Solid-oak side panels with solid aluminum panels (other chassis option possible upon request , price might vary)
