locking banana speaker cable connector wbt price is for an essentially identical connector is $72. 00 per pair this is a unique banana. Standard bananas do not always provide a tight electrical fit and will sometimes simply fall out on their own. Our locking banana provides a tight pressure fit as good any spade; plus the convenience of quick connect and disconnect. It will accept wire sizes up to 8 gauge. If you will be using a small size wire such as 14 gauge, you can double it over before inserting it into the connector. the wire can be attached by either soldering or using the included screws that will hold it in tightly. this connector is of the highest quality with no loss or degradation. It is beautifully machined and gold-plated. Ours may look similar to those of our competitors, however, all others we have examined are made of brass with gold plating on top. Brass which is only 67% copper is not a very good conductor of electricity and consequently there is a preformance sacrifice. Ours are made of an aloy that is 90% copper, 10% tin and then plated with gold. (one hundred percent copper would be to soft for this purpose). The ten percent of zinc we add to the copper gives it the required strength and hardness. Because it is mainly copper, it conducts electricity far better than those of our compettiors. It is more costly to produce, but it is truly a premium banana connector. It is essential that a speaker connection be of the highest integrety to ensure there is no comprise in performance of your system. We believe this is the best banana connector available.
