A:AnswerHello, yes these banana plugs will work perfectly for that speaker wire. The banana plugs use a series of set screws to tighten down onto the speaker wire. Just tighten the screws onto the cable to make a secure connection and you'll be good.
A:AnswerThese work quite well, actually. the design of these "connectors" allows for significant contact between the wire itself and the connector surface via the "screws". I used them on 11 and 14 gage wire and am pleased with the results of the connectivity they offer. Plus, they save time in the assembly process. Can't address the "look", only the effectiveness of the intended purpose. Hope this helps.
