This is now our preferred way to terminate speaker cables (not just QED). In our opinion this is the highest quality form of termination and is a compression connection using a special termination tool which we have invested in. The new Airloc plugs themselves are very high quality over their predecessors.Now that we can do Airloc terminations in-house our prices are under 1/2 the price we were charging when QED had to do this work.Note: Airlocs are not suitable for DNM Reson Speaker cable.
