Our take on the AudioQuest Rocket 33

by Kristen Schaub

Many of today's speakers can be "bi-wired." They feature two sets of connectors, which provide separate inputs for the woofer and tweeter. Until now, bi-wiring required using two regular sets of speaker cables, but AudioQuest's innovative Rocket 33 single bi-wire cable delivers the sonic benefits of conventional bi-wiring along with much lower cost and simpler hookup. They enable your speakers to reproduce sound as cleanly and faithfully as possible using a single cable. You'll enjoy sound that's spacious, finely detailed, and beautifully balanced.

The benefits of bi-wiring
When a full-range signal is sent through a single speaker cable, the interaction of the magnetic fields created by the different frequencies can negatively impact the sound produced by your speakers. In particular, large amounts of bass energy can interfere with more delicate high frequencies. Bi-wiring transfers audio signals separately to your speaker's woofer and tweeter inputs, eliminating this distortion-causing interaction. If your speakers can be bi-wired, they should be for optimum performance.

Solid conductors improve accuracy and clarity
Each of the cable's six conductors is a single, unbroken strand of pure copper, which ensures highly efficient signal transfer with minimal loss. Solid conductors eliminate electrical and magnetic interference that can add brittleness to the sound of multi-strand conductor cables.

Precise cable geometry
The Rocket 33 uses a precise combination of different size conductors: 21-, 19-, and 17-gauge conductors for the high-frequency signal, and 20-, 18-, and 16-gauge conductors for the low-frequency signal (see more photos). This difference in diameter reduces the possibility of distortion caused by any particular conductor's sonic "signature." A specialized spiral arrangement of the three conductors in each bundle minimizes potential signal interaction, resulting in sound that's clearer and more dynamic.

Bi-Wiring: AudioQuest Rocket 33 is a Single-BiWire cable. When the halves are separated at the speaker end, the Dual-Triple design turns Rocket 33 into a true Double-BiWire set, thanks to the magnetic autonomy of each tri-conductor section. On its own, one tri-conductor group would be a little light-weight in performance as it is biased towards treble finesse. The other tri-conductor group is biased toward the bass; its more forceful and lacking ultimate resolution. Together they form a completely optimized full range design. When separated, the Dual-Triple design lets Rocket 33 be a maximum performance Double-BiWire in a single cable.

  • Treble Group:
    • 21 AWG Solid Perfect-Surface Copper (PSC) Conductor
    • 19 AWG Solid Long-Grain Copper (LGC) Conductor
    • 17 AWG Solid Long-Grain Copper (LGC) Conductor
  • Bass Group:
    • 20 AWG Solid Perfect-Surface Copper (PSC) Conductor
    • 18 AWG Solid Long-Grain Copper (LGC) Conductor
    • 16 AWG Solid Long-Grain Copper (LGC) Conductor

Solid Conductors: The use of solid conductors eliminate harshness and confusion due to strand interaction. All six of Rocket 33's conductors are solid. Solid conductors prevent strand interaction, a major source of cable distortion. Electrical and magnetic interaction between strands in a conventional cable is the single greatest source of distortion, often causing a somewhat harsh, dirty and confused sound. Solid conductors are the most important ingredients enabling Rocket 33's very clear sound. Whether a conductor is solid or stranded, skin effect is a prime distortion mechanism in speaker cables. Rocket 33 very simply keeps this effect out of the audio range by using conductor sizes that are below the threshold for audible distortion.

Long-Grain Copper/Perfect-Surface Copper: Rocket 33 uses a combination of Long-Grain Copper (LGC) and extremely high-purity Perfect-Surface Copper (PSC). All conductors are solid, which prevents strand interaction, a major source of distortion. Surface quality is critical because a conductor can be considered as a rail-guide for both the electric fields within a conductor, and for the magnetic fields outside the conductor.

  • Long-Grain Copper (LGC):  LGC has fewer oxides within the conducting material, less impurities, less grain boundaries, and definitively better performance.
  • Perfect-Surface Copper (PSC): The smooth and pure PSC further eliminates harshness and increases clarity.  The astonishingly smooth and pure Perfect-Surface eliminates harshness and greatly increases clarity compared to OFHC, OCC, 8N, and other coppers. High-purity PSC further minimizes distortion caused by grain boundaries, which exist within any metal conductor.

Dual-Triple Geometry: The relationship between conductors defines a cables most basic electrical values (capacitance and inductance). However, even when those variables are kept in a reasonable balance, the relationship between conductors can be varied in ways that greatly affect the sound. The Dual-Triple construction of Rocket 33 allows for significantly better dynamic contrast and information intelligibility than if the same conductors were run in parallel. The specific 3-cross geometry used in each half of Rocket 33 maximizes this advantage.

Spread-Spectrum Technology (SST): Any single size or shape of conductor has a specific distortion profile. Even though radially symmetrical conductors (solid or tubular) have the fewest discontinuities, any particular size does have a sonic signature. SST is a method for significantly reducing the awareness of these character flaws by using a precise combination of different size conductors. The six different SST-determined conductor sizes used in Rocket 33 allow an exceptionally clear, clean, and dynamic sound.

Directional: The PVC "pants" on either end of Rocket 33 are marked "Speaker End" or "Amp End". Please use cables in the direction required.

Cold-Weld Terminations: Superior AudioQuest connectors allow Rocket 33 to be securely attached to any type of equipment. AQ ends are dull looking because there is no harsh sounding shiny nickel layer underneath the silver. The connection between the plug and conductors is made using AQ's Cold-Weld system which provides a superior connection that ensures that the structural integrity of the conductor is kept completely intact. The Cold-Weld system refers to a combination of high pressure at the point of contact and the use of copper impregnated paste. A controlled amount of pressure is used to essentially make the conductor and connector mechanically "as one" without the use of heat. The copper bearing paste acts as both a copper oxide retardant, and as well as a very effective contact enhancer. AQ's Cold-Weld system ensures a practically perfect connection.

Rockin' speaker cables

Written By Jimmyjames, Raleighwood on Thursday, April 17, 2014
Crutchfield Customer Review (What's this?)
Great cable at a fairly good price. You will have to pay a lot more for better and these may just be good enough. I've owned cables costing up to $2000 a pair. Went minimalist and sold all my high priced speaker cables. Still have some PCOCC speaker cables in my reference system that I got for next to nothing. They are no longer available. The Rocket 33's give them a run for their money. They just open up the sound and get out of the way. Same old cliches still apply. I hear deeper into the music. There really is more "THERE", there. It is quite a jump from lamp cord or another retailer's Mega Cable to the Rocket 33's in price and sound. It is a jump worth taking.
Open, airy, detailed sound.
A little spendy for an entry level or mid level speaker cable but it sounds better than it should for the money.

Crutchfield Customer Review (What's this?)
A friend encouraged me to replace my 14 gauge speaker cable with AudioQuest Rocket 33. I must admit, I was very skeptical, but I ordered a pair from Crutchfield. They arrived the next day! Installation was easy. My friend was right. The speakers absolutely have a fuller, more three dimensional sound, with better detail and well defined bass.
Much improved sound! Better cable management.
They ain't cheap.

I really like these Cables.

Written By Darryl G, Wichita on Wednesday, June 05, 2013
Crutchfield Customer Review (What's this?)
So Far I'm enjoying the sound from these Bi-wired speaker cables compared to the sound out of my speakers when I ran 2 sets of cables to my receiver. they seem to really shine when I have my two towers speakers (Polk RTi A7's) hooked up to a 2 channel integrated amp like my "Peach Tree Decco 65" And everything I have is still pretty new and has not been broken in yet!
really improves the sound from my Integrated Amp.

Crutchfield Customer Review (What's this?)
Did it make a difference, yes I think so. Worth the investment, if you have decent electronics and speakers yes. Connects between a NAD amplifier and B & W speakers and the sound is crystal clear even up to higher volume.
Easy to connect, brings out the sound.

I'm Impressed

Written By Leo, Rosemount, MN on Thursday, February 23, 2012
Crutchfield Customer Review (What's this?)
I used these cables to bi wire a pair of Polk Audio LSI9 speakers. I have used this speakers for several years using single 12 gauge speaker wire to each speaker. I am using a Yamaha RX797 to run the speakers and have always been impressed with the sound but decided to go the bi wire route after reading several favorable reviews online. Wow. What a difference. I have immediately noticed a significantly improved sound stage with much sharper clarity. I have always been skeptical of expensive speaker cables but these cables were definitely worth the investment.

If I had to....

Written By Brandon, Maine on Monday, January 10, 2011
I have had these for almost a year now. I have switched from several AVRs and speakers while implementing these wires. For a comparison? They are in my opinion just wire, but with that said; they do bring a lot of details to life. My speakers seem to have a bit more life to them when using these cables versus the regular "got at my hardware store" cables. They look fantastic, and the warranty on them is amazing. You feel the copper inside, it is flexible, but not over the top. The wire is thick, and they implement silver bananas. The only down fall would be the price. For someone who is just looking to listen to music and end at that, I would not recommend this product due to the steep price. For someone who is looking for their music to come to life, to hear what is meant to be heard, I would fully back these up. I have mid line equipment, and every time I have upgraded my equipment, these cables have continued to bring more to every song each time I have listened to it.

1 question already asked

Going from an Onkyo Integrated amp into PSB B6 speakers. Would Using both A-b speaker outs form the Onkyo into both sets of Inputs on the speakers be the best way to wire these, would hat actually be Bi_wiring ,and would it improve the sound? [ Matt  Feb 03, 2014 ]
3 answers
  • This is bi-amping, not bi-wiring. Bi-amping might damage the speakers. First, I would replace the PSB jumpers with short speaker cables and then use conventional cables to power the speakers. Determine if there is a noticeable improvement in the sound. Then contact PSB and ask them if bi-wiring would result in a noticeable improvement in the sound. Based on their reply, make the determination to upgrade the cables to either conventional or bi-wire. [ ROBERT   Feb 04, 2014 ]
  • Hi Matt, I suppose I am a good person to ask this question, because my bookshelf speakers also happen to be PSB B6s. The end of the AudioQuest Rocket 33 cable with two banana plugs (one black and one red) should be inserted into either the A or the B speaker outputs on your amp. The other end of the speaker cable with four banana plugs (one black treble, one black bass, one red treble, and one red bass) should be inserted into the PSB B6's inputs. First you'll need to remove the four little plastic centers on the speaker's four inputs. Everything is color coordinated, so you can't miss. Since I installed my Rocket 33s, my speakers definitely sound fuller and clearer. The cables are pretty pricey, but the improvement in sound quality was worth the additional expense to me. Ed [ EDWARD A   Feb 03, 2014 ]
  • No, the end with 4 plugs goes to the speaker. The end with 2 plugs would go to the receiver. [ RICHARD   Feb 03, 2014 ]
