Acoustic Revive BWA-4 Bi-wire adapter is a Set of 2 bi-wire adapters to install on bi-wiring speakers when only a stereo cable is used.

Principle and structure

Expensive jumper wire is meaningless!
Many speaker recently adopts bi-wire input terminal. This is to prevent from backward electromotive force of woofer effecting high frequency which effects the sound quality.Originally, two amplifier drives the woofer and tweeter separately, or one amplifier connected by two speaker cable. One cable connected to woofer, and the other cable to tweeter. This is the right correct connection, but it seems to be that not many people knows that.
Because not many people knows this fact, there are manufactures starting to sell expensive jumper wire which is meaningless. Correct way of connecting speaker cable onto bi-wire speakers is to remove jumper and connect separately to woofer and tweeter by using two speaker cables. But problem is a lot speaker cables are becoming very expensive. So it is very difficult to buy two sets of speaker cable newly. Also some of amplifier only have one set of speaker terminal.
ACOUSTIC REVIVES`s bi-wire adapter BWA-4 will solve the problem. Cut off 30cm from the tip of speaker cable, and from BWA-4 to speaker terminal, connect the cable separately to woofer and tweeter. This will give you almost pure bi-wire connection and prevents from backward electromotive force.

Ultimate conductivity which does not cause sound quality deterioration!
We have raise the conductivity performance to the limit. This is to make sure sound quality does not deteriorate by inserting an adapter between the amplifier and speaker. As for materials we have adopted rhodium plated lead less brass and for the screw, gold plating. Also to make sure the cable is fixed firmly, double screw structure is adopted. For these parts, -196°C Super cryogenic treatment is been done to increase the conductivity.

Vibration control structure to improve sound quality!
BWA-4 is made from 2017 Duralumin and brass. This different metal combination is an effect of controlling vibration. This vibration control effect quickly eliminates vibration from speaker terminals and speaker cables to improve sound quality.

Diameter of input cable insertion side 4.3mm
Diameter of output cable insertion side 5.9mm
Input side can attach a Y rag too

Acoustic Revive: Once you listen to it, you know the difference. The accessory and cable that not only changes sounds. The true accessory and cable manufacturer that revives the sound to most natural and real sound.

Our philosophy: "To take away nothing and to add nothing".
Our goal: "To purely transmit the original source signal and to emit the most realistic sound-stage into the listening room".

This is why we created ACOUSTIC REVIVE.

Acoustic Revive is a Japan producer of audio hi-end accessories and cables designed and engineered to obtain the best results today available. Construction quality is superb so they are also used in the major recording company.

The Japanese school of hi-end accessories for the fine optimization of an audio system, is here. Acoustic Revive takes audio tweaking very seriously, introducing materials and techniques extremely advanced:

- Using aerospace materials like the Duraluminium or physiological materials like natural quartz.
- Apply special material processing like the Japanese traditional forging process of "tripleC" cables technology.
- Doing deep cryogenic treatments that, modifying the molecule structure, better the signal transmission.
- Employ demagnetizing treatments, to cancel the influence of the magnetic fields.
- Dimension and design basing on the Gold Section.
- Introduce the so-called "virtual grounding" concept.

When an audio hi-end system is treated with Acoustic Revive accessories, it sounds more detailed, natural, smooth, and also more deep, powerful and dynamic. Every Acoustic Revive product is 100% "Made in Japan".

Please note that due to distribution agreements, the Acoustic Revive products can only be shipped within Italy.

      Minimali, semplici e comodi da usare ( no wi-fi & Bluetooth), il punto di forza dei Cowon serie Plenue è il loro suono naturale.
