Analysis Plus Silver APEX Speaker Cable - 12 Foot - Banana to Banana - Pair

Analysis Plus Silver APEX Speaker Cable — 12 Foot — Banana to Banana — Pair

What It Does in Your System

The Top of the Analysis Plus Silver Line

Analysis Plus has built cables in Flushing, Michigan since 1993. The company started as a scientific research and design firm, and it still designs cables using computer modeling and measurement rather than tradition. Silver APEX is the most advanced speaker cable in their silver range.

This is a reference-level cable for a system where the rest of the chain is already sorted. At 12 feet it suits a wide room, a long wall, or a setup where the amplifier sits off to one side.

Hollow Oval Conductors, Nested Three Deep

Most cable uses conductors that are round or flat. Analysis Plus builds theirs as a hollow oval tube — the patented geometry the company is known for. Silver APEX takes it further: a hollow oval inside a hollow oval inside a hollow oval, three 9 AWG conductors in all.

The idea behind the shape is current distribution. At high frequencies, current tends to crowd toward the outside of a conductor. Analysis Plus says the hollow oval spreads current more evenly, which keeps resistance low even at the top of the audio band.

A Double Shield, Which Speaker Cable Rarely Has

Shielding is common on interconnects and rare on speaker cable. Silver APEX has two shields — the nested conductor structure does double duty, wrapping the inner conductors in metal.

Analysis Plus credits this for the cable's very low noise floor. In practice, shielding matters most when your cable runs near power cords, dimmers, or wireless gear, which is common in a long 12-foot run.

Is This Right for You?

Worth confirming before you order:

• Your binding posts accept bananas. This pair is terminated with banana plugs at both ends. If either your amplifier or your speakers use posts that will not take a banana, order the spade version instead.
• 12 feet is the longest standard length. Measure the real routing path, not the straight-line distance. Analysis Plus builds custom lengths through their Custom Shop if 12 feet will not reach.
• This is a full-range cable, not a bi-wire set. Two connectors per end. If your speakers have four posts and you want to bi-wire, this is not the configuration you need.

Setup & Installation

Connect one cable to each speaker, red to red and black to black. Banana plugs push straight into the binding post — no tools, no torque. Give each plug a firm press so it seats fully.

This is a heavy 9 AWG cable, so plan the routing. Keep a gentle curve at each end rather than a sharp bend, and give the plugs some slack so the cable's own weight does not pull on the connection. Where you can, cross power cords at a right angle instead of running alongside them.

Features & Specifications

Patented Hollow Oval Geometry
An oval tube conductor that Analysis Plus designed to distribute current more evenly than round or flat wire.

Triple-Nested Conductor Design
Three 9 AWG hollow oval conductors, each seated inside the next, in Analysis Plus's most advanced speaker cable structure.

Double Shielding
Two layers of shielding for a low noise floor — uncommon on speaker cable at any price.

Silver-Over-Copper Conductors
High-purity silver over an oxygen-free copper core, where the copper gives the hollow oval the strength to hold its shape.

Frequently Asked Questions

Why is the conductor hollow?
At higher frequencies, current concentrates near the surface of a conductor and largely skips the center. A hollow shape puts the metal where the current actually travels. Analysis Plus reports lower resistance at the frequency extremes as a result.
