Analysis Plus Black Mesh Oval 9 Speaker Cable - 18 Foot - Banana to Banana - Pair

What It Does in Your System

The Cable That Built This Company's Reputation, at Long-Run Length

Oval 9 is the design that made Analysis Plus a name in audio — well enough regarded that reviewers kept remarking on how little it costs relative to what it does. Black Mesh Oval Nine is the current version, with improved connectors, a dielectric with faster rise time, and geometry re-optimized for more uniform current distribution.

This is a matched 18-foot pair with bananas at both ends. Eighteen feet handles a large room, an amplifier well away from the speakers, or a run that has to travel the perimeter rather than cross the floor.

Hollow Oval Geometry That Keeps Resistance Flat Across the Band

Analysis Plus is an engineering firm first — the Michigan company earned its name modeling and testing cables for other manufacturers before deciding it could do better itself. Their simulations showed that round conductors suffer badly from current bunching and skin effect, so they developed a patented hollow oval cross-section instead.

A woven pattern places every wire statistically as close to the return current as every other wire. Current density stays even and resistance barely changes with frequency — which matters progressively more the longer the run gets, because whatever a cable does wrong, it does for the whole distance.

Nine Gauge of Copper, Which This Length Genuinely Uses

This is a substantial cable — 9 AWG of high-purity oxygen-free copper. Over eighteen feet, conductor mass is what keeps series resistance low enough that your amplifier maintains its grip on the woofer all the way to the speaker. Analysis Plus points this cable at lower-sensitivity speakers, longer runs, and higher listening levels, and this length sits squarely in that territory.

Analysis Plus uses a flexible braid rather than solid conductors, which kink and deform in ways that degrade the signal. The oval cross-section and braided construction can't be machine-terminated — each cable takes over an hour of handwork to complete.

Is This Right for You?

A few things to confirm before ordering:

• Measure the real routing path. At eighteen feet you're going around furniture, along baseboards, or through a doorway. Walk the route with a tape measure and add a little for dressing the cable at each end — a run this long isn't one you want to redo.
• Your binding posts accept bananas. Bananas are the most universal connection and work with standard five-way posts and shrouded EU-style terminals alike. If you'd prefer spades, Analysis Plus offers this cable with their T1 spade instead.
• This is the full-range configuration. Two conductors per end, one cable per speaker. If your speakers have separate bass and treble binding posts and you want to bi-wire, Analysis Plus builds the Bi-Oval 9 for that.

Setup & Installation

Insert the banana plugs into the binding posts on your amplifier and speakers, observing polarity — positive to positive, negative to negative, at both ends. Bananas seat with a firm push and hold by spring tension, so no tools are needed. Confirm polarity before you dress the cable into place and wire both channels identically, since tracing a reversed channel after a long run is fixed means pulling the whole thing.

The cable measures roughly 20mm by 8mm in cross-section — a wide flat oval rather than a round bundle. That profile lies flat along baseboards and under rug edges, which is what makes a run this length practical to conceal. Nine-gauge conductors don't like tight turns, so plan generous radii at every corner, and keep the run clear of AC power cords where you can.

Features & Specifications

Patented Hollow Oval Geometry
Minimizes current bunching and skin effect so resistance stays nearly constant across the audio band.

Woven Braided Conductor
Every wire sits statistically as close to the return current as every other, distributing current density evenly for better signal transfer than solid-conductor designs.

9-Gauge Oxygen-Free Copper
A massive conductor that keeps series resistance low over long runs, preserving bass control and dynamics all the way to the speaker.

Handcrafted Termination
The oval cross-section and braided construction require hand assembly — over an hour of work per cable.

Frequently Asked Questions

Is this a pair or a single cable?
This is a matched pair — two 18-foot cables, one per speaker. Everything you need to wire a stereo system is included.

Does eighteen feet of cable hurt performance?
Length costs you very little when the conductor is sized for the job, and nine gauge is generously sized. What degrades long runs is series resistance eating into your amplifier's grip on the woofer, and heavy copper is the direct answer. The hollow oval geometry additionally keeps resistance from varying with frequency across the distance.

What's the difference between this and the Bi-Oval 9?
Same conductor, same geometry, same gauge. The Bi-Oval 9 uses four conductors so your speaker's bass and treble binding posts each get their own pair. This standard version is what you want if your speakers have a single set of posts.
