Speaker Cables

Ultrasonically-Welded Connections on Terminated Speaker Cables

Blue Jeans Cable is America's only vendor of ultrasonically-welded speaker cables; our ultrasonic welders from Sonobond (manufactured in West Chester, PA) allow us to weld (yes, that's "weld," not "solder") locking banana plugs, spades and pin connectors to any of our speaker cable products. Ultrasonic welding literally fuses the copper wire to the brass or copper connector without using the heat of conventional gas or arc welding, for a tremendously strong physical connection, low contact resistance, and low susceptibility to corrosion. To read more about this unique process, see our article: Ultrasonic Welding at BJC.

Speaker cable is a bit different from a lot of the interconnect cables we handle, in several respects. 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. The low impedance of the circuit, meanwhile, makes capacitance, which can be an issue in high-impedance line or microphone-level connections practically irrelevant. 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. 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 answer to keeping conductivity high is simple: the larger the wire, the lower the resistance, and the higher the conductivity. We offer a few alternatives in large-gauge speaker cable, either raw or terminated, as follows:

Belden 5T00UP Cable

Belden 5000 series Cable:

Our principal speaker cable is simple two-conductor cable, in 12 or 10 AWG; in gray, these are the Belden 5000 series (5000UE for twelve, and 5T00UP for ten AWG), and in white, we carry our own versions called simply "Twelve White" and "Ten White." Both the 10-gauge and 12-gauge versions consist of two separately insulated conductors, twisted together and wrapped in an outer PVC sleeve; the gray version of the 10-gauge 5T00UP is shown at right. Whether in white or gray, or 10 or 12 AWG, all of these cables are UL-listed and NEC-rated for in-wall use (the NEC rating for 5000UE and Twelve White is CL3R; for 5T00UP it's CL3, and for Ten White, it's CL2).

Canare 4S11 star quad cable

Canare 4S11 Cable:

Canare 4S11 is a "star quad" 14-gauge cable, with four conductors together in one outer jacket; it is popular for bi-wiring (where separate wires run to each of four speaker terminals, two of which drive the high and two of which drive the low-frequency elements of the speaker assembly). When conventionally wired, star quad speaker cable has the advantage of reducing the EM field around the cable, which will tend to diminish the effect of the signal in the speaker cable upon nearby interconnects--though this is not, in most applications, a significant concern. 4S11 is a very pleasant-looking cable, with a round matte gray jacket, and is quite large--about 3/8 inch in diameter. 4S11 is not UL-listed or NEC rated. We offer this cable raw, and terminated either in single-wired or bi-wired configurations.

Welded Termination Options

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). 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. 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.

Don'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 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 9.2 will fit almost any post, but ideally one should use the smallest size that the post can accept.

Terminal-strip fork and binding-post spade, compared

Forks Versus Spades: Binding Posts or Terminal Strips?

The welded spade lugs depicted above are made to fit conventional binding-post terminals such as are typically found on speakers. The opening of the spade lug is large and will fit these posts. If, however, you need connectors to fit terminal strips, such as are found on some amplifiers, these spades are much too large. For these applications we offer small soldered-on fork terminals which are intended to fit these terminal strips -- we have these in #6 (.138 inch, 3.5 mm), #8 (.164 inch, 4.17 mm) or #10 (.19 inch, 4.83 mm) size; all of these measurements are of the INSIDE of the fork; the external width ranges from 8.2 to 8.7 mm, which will fit most terminal strips.

Banana Plugs and Spade Lugs

DIY Termination Hardware: Bananas and Spades

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. We carry banana and spade lugs which we import directly from a supplier in Taiwan; these are gold-plated and are of a compression screw termination type--that is, one inserts the wire through the rear portion of the connector, flares the wire to make it overlap the end of that rear portion, and then screws the front portion of the banana or spade onto the threads (see our speaker cable termination instruction page). Properly done, these terminations are extremely solid and can't be removed even with very strong pulling. Because these plugs have a conductive metal surface on their entire exterior, we recommend using a bit of heatshrink tubing (included with the connectors) to provide an insulating layer which will help protect against the possibility of shorting one connector to the other. Bear in mind, when choosing between spades or bananas, that because spade lugs have to go onto binding posts sideways, they really aren't practical for many of the surround amps on the market today, as there just isn't room for them. If in doubt, you're better off with banana plugs, which plug right into the ends of most binding posts.

Locking banana plugs

Locking Banana Plugs:

We also offer a DIY version of our locking banana plug; this plug, shown at right, has a tightening collar which can be used to expand the width of the banana after insertion, for an especially secure installation. The speaker wire is fed into the rear of the plug, and the wire is then clamped in place with a pair of brass setscrews. As with our standard bananas, instructions for terminating these are contained on our speaker cable termination instruction page.

Raw or Finished--Your Choice

We offer all of the speaker wire above in raw lengths, and we offer the banana and spade terminals in pairs. Terminating these yourself is easy to do, and instructions for termination are contained on our speaker cable termination instruction page. Alternatively, we also can terminate your cables for you here; our terminated speaker cables use the locking banana plugs shown above and/or the compression-style spade lugs, as you specify.
