Principle and structure

Expensive jumper wire is meaningless! Many speakers adopt bi-wire input terminals. This is to prevent the backward electromotive force of bass drivers effecting high frequency which effects the sound quality. If two amplifiers drive the woofer and tweeter separately, or one amplifier connected by two pairs of speaker cable, one cable connected to woofer, and the other cable to tweeter. This is the correct method of connection, but it seems to be that not many people know that.

Because not many people know this fact, there are manufactures starting to sell expensive jumper wire which is meaningless.  The correct way of connecting speaker cable onto bi-wire speakers is to remove the jumper and connect separately to woofer and tweeter by using two speaker cables.  But the problem is that a lot of speaker cables are becoming very expensive.  So it is very difficult to buy two sets of speaker cable. Also most amplifiers only have one set of speaker terminals.

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-were connection and stops backward electromotive force.

Ultimate conductivity which does not cause sound quality deterioration!

We have raised the conductivity performance to the limit.  This is to make sure that sound quality does not deteriorate by inserting an adapter between the amplifier and speaker.  As for materials we have adopted rhodium plated leadless brass and for the screw, gold plating.  Also to make sure the cable is fixed firmly a double screw structure is adopted.  For these parts, -196°C Super cryogenic treatment has 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.
