the better solution compared to metal bridge

The cable lugs are indeed made relatively simple but it stable and so that they fulfill their purpose fully.
They fit in 6mm and 8mm, with me are 8-Use the connection terminal of the speaker.
Big advantage: even in 8-terminals the contact surface is still very large, so that the screw
the connecting terminal can be tightened clean because nothing moves more. That I know also different if
is too little squish available.

The cable of the bridge is a 6mm² OFC and silver. Whether the silver which brings I dare times to
doubt it can hurt but not :-). Surely but a good compromise, either normal
OFC Speaker Cable used or even something better / more expensive material. High-Ender, if necessary, eh bi-wiring
apply.
Small snag: The red and black insulation slips relatively easily back and forth.

In Oehlbach a 4-star product, from me there's 5 star, do not be favorable bridges found.
Suitable as a sensible tuning measure, mainly because the bass is taking shape in me.
