Banana plug connector2/17/2024 The important attributes of a banana plug or spade lug are its ability to be reasonably well tightened onto the cable and its noncorrosive coating-the job of a banana or spade is very simple otherwise, as all it needs to do is provide a mechanically stable connection to the binding post and to the speaker wire. The 9.2 will fit almost any post, but ideally one should use the smallest size that the post can accept.ĭIY Termination Hardware: Bananas and Spades The 6.3mm fits many posts, but we offer the 7.0 as well because we've found that some posts are just a shade over the 6.3 size. The spades will fit most types of binding posts, and the terminal end is angled at about 25 degrees from the shaft - however, these spades are made of gold-plated copper and so can be bent, using a bit of care and a couple of pairs of pliers, to any angle you like.ĭon't know what size spade is best? We have a measuring card with cutouts that can fit your posts, which we'll mail to you free of charge - just drop us a note or give us a call. The pin connector, designed for use with wire-clip type terminals, presents some special issues and cannot be ordered on this page but can be ordered here: Speaker Cables with Pin Connectors. Our ultrasonically-welded terminations include locking banana plugs, BFA plugs (these fit binding posts that have a central pin that prevents a conventional banana from being used), pin terminals, and spade lugs in 6.3mm, 7.0mm and 9.2mm internal sizes (only the 6.3 and 9.2 are shown at right). Pin terminal, 6.3mm spade, 9.2mm spade Welded Termination Options We offer a few alternatives in large-gauge speaker cable, either raw or terminated, as follows: The answer to keeping conductivity high is simple: the larger the wire, the lower the resistance, and the higher the conductivity. While one can spend thousands of dollars on exotic speaker cable, in the end analysis, it's the sheer conductivity of the cable, and (barring a really odd design, which may introduce various undesirable effects) little else that matters. The biggest issue in speaker cables, from the point of view of sound quality, is simply conductivity the lower the resistance of the cable, the lower the contribution of the speaker cable's resistance to the damping factor, and the flatter the frequency response will be. The low impedance of the circuit, meanwhile, makes capacitance, which can be an issue in high-impedance line or microphone-level connections practically irrelevant. Because speakers are driven at low impedance (typically 4 or 8 ohms) and high current, speaker cables are, for all practical purposes, immune from interference from EMI or RFI, so shielding isn't required. Speaker cable is a bit different from a lot of the interconnect cables we handle, in several respects.
