Question How many banana plugs do I need to buy for the Ventriloquist system?

A banana plug might make installation of the rear center easier. Unfortunately, the rear center has unusually small holes, which are too tight for most plugs. We'll, we've found a RadioShack banana pair that fits well, although they require some soldering to the wire.

Use the Catalog number in the search box at Radioshack.com
Catalog number: 278-307
Title: Banana Plug
Price: $7.99
Brand: Tandy Elect Pkg-440068

June 7th Update:
For the rest of your system, bananas can be useful when you unplug and plug-in speaker cable over and over. They offer a reliable, springy connection, something that bare wire just can't. With bare wire, you must be extra careful to fully tighten the binding posts each time. Plus, bananas reduce the risk of crossing wires.

To add Parts Express Dual bananas to a 6 channel system , you would need:

10 for the center and left/right fronts (pairs: 3 -> 3 -> 2 -> 2)
4 for the left and right rear surround (pairs: 2 -> 2)
1 for the rear center surround (pairs: 1 -> 1 pair of Radioshack bananas)
15 Parts Express Dual bananas plus the special Radioshack pair for the rear center (the rear center will have the jumper installed, so only one Radioshack banana pair is needed).

For a 5 channel system using the special rear center to simulate 6 channels
Using the rear center matrixing feature, you would need 14 Parts Express dual bananas and two pairs of the special Radioshack plugs. You would double up the wire on the rear satellite plugs and run them to the rear center.

For a 5 channel system
You would need 14 Parts Express dual bananas and no special Radioshack plugs at all.

P.S. For the Parts Express bananas, you might consider getting two colors to help keep track of left and right channels. For example, we sometimes use red for right and center, black for left. That would be six black ones, and the rest red. We then use a marking on the banana plug to keep track of polarity. You also need a small flat-head micro-screwdriver for the Parts Express bananas.

They are expanding units. If you haven't already, try unscrewing the part that has the boot. Once unscrewed, it should just slide in. Then you screw the boot part back down and it is tight.

  • Anybody got pictures of how the banana plugs are attached to the speakers? I guess I want to understand how those dual banana plugs will work. (okay so I get it, 1 pair of the banana plug for each set of terminals)
  • Also I don't get how the RS banana will work on the rear center. It says to connect both blacks together and both reds together. How can we do that with just one pair of banana plugs? (okay so I will use the jumper cables provided in the box of the VTF and just plus the banana on one of the terminals)
  • But how come you guys are only counting 16 or 14? In my count (and if it's correct based on Figure 4: Hookup for 6.1 receivers of the manual) we will need 18 banana plugs for all the speakers except the rear center with which we'll use the radio shack plus # 278-307. The breakdown is 5 pairs (10 pieces) for the center and 4 pairs (8 pieces) for the satellites.
  • So in actuarial for a 6.1 setup, we need 18 pieces of PartsExpress banana plugs and 2 pieces of Radio Shack banana plugs. Of course this excludes how many you'll need for the terminals on your receiver.
  • Can anyone suggest a good connector/plus I can use for spring clips on my receiver? I got a Panasonic XR-50. Unfortunately it only has the screw type terminals for the front speakers and the rest are spring clips (excluding the subwoofer out which is coaxial).

The parts express plugs are a pair (count as two) - hence only 16 plus the radio shack.

How many banana plugs do I need to buy?

I have ordered an extra (rear) speaker for the VT12 to setup a 7.1 system. Will this also require the Radio Shack (smaller) banana plugs?

Banana Plugs

Ok I give up..How do you connect those Parts Express Dual Banana Plugs to the Wire? I see no moving or screwing part when I look at it. Just empty holes. These dont require solder right? How do they work??

Monoprice Banana Plug Fits Rear Center

FYI, after my useless soldering skills failed to connect my speaker wire to my small Radio Shack banana plugs, I happened to try these solder type plugs from Monoprice that I was planning to use for my other VT-12 satellite speakers:


These plugs worked fine in the rear center but are now too small for the other speakers and just fall out. You don't have to solder them either as the rear section screws off and can be used as a twist in type plug.

Hope this helps...

go to monoprice.com. I got 18 pairs for $1.50/pair. Very good quality banana plugs with gold plated contact.
