The Vertex AQ Moncayo Speaker Leads

The Vertex AQ Moncayo Speaker Leads deliver astonishing musical performance in any high-end hi-fi system context. They add significantly to transparency realism and presence, enabling far greater levels of enjoyment and emotional connection to your music.They do this because they are a key element in the Systematic Approach strategy. Their performance lies in their ability to significantly reduce damaging artefacts which pollute your sound.

There is one important rule in the Systematic Approach that states ‘when you start to upgrade within the signal path (with Vertex cables) you should generally start with the speaker cables first’. This is because, within the signal chain, the feed between your amps and speakers has the highest level of vibrational energy (caused by the speakers). And because your speaker leads are usually quite long, they can pick up considerable amounts of RFI and inject it back into your system.

There are three main performance levels in the Moncayo speaker leads are all essentially the same in their overall construction. They all comprise a high quality lead with two large boxes someway along its length. They are designed to carry out the following functions:

  1. To provide a low impedance connections between amp and speakers to effectively deliver the audio signal and reduce Radio Frequency noise.
  2. To reduce the levels of structural vibration within the cable and the components to which it is connected.
  3. To lower RFI levels within the speaker feed, and consequently within the speakers and amplifier outputs (HiRez version)

The Moncayo speaker lead really is a key element of the Systematic Approach. Once the external system artifacts are dealt with (by using our mains and the LeadingEdge support products), the next big area to be tackled is invariably the high-energy path between amplifier and speakers. A system which does not have control of the unwanted vibration between amp and speakers always sounds distorted and cluttered to our ears.

Here’s a little thought! Consider that we push electrical energy into our speaker drivers and then convert the majority of that energy  into vibration – the very sound we want to hear. But bear in mind that drivers do not vibrate the air in our rooms very efficiently; Newtons Third Law states, ‘for every action there is an equal and opposite reaction’ – so 50% of the vibration energy in the driver must be fed back into the driver housing. The motor is connected by wires back to the crossovers, binding posts and ultimately, back to your amp – so there is a very efficient path there, feeding vibration back, which will cause significant intermodulation distortion within your system. Don’t forget also that on most amps the negative binding posts are connected to Earth, so the driver energy has a clear path around all the Earths in your system.

Configuration

The Moncayo speaker leads come as matched pairs and each lead is fitted with two 220mm x 105mm x 45mm acoustic absorption modules. The modules are positioned nominally 800mm from the ends of the cables (this can be tailored to individual requirements through your Vertex dealer – usually at no additional cost). Note that the minimum length of the full Moncayo is 3.0m – it is not practicable to manufacture shorter lengths with 2 acoustic absorption modules – for lengths below 3.0m only one module is fitted (but this may reduce the performance benefits – discuss carefully with your Vertex dealer).

Because of the physical construction of our cables you need to consider much more carefully the positioning and routing issues. And when deciding what length you may require, take account of the need to position the heavy acoustic absorption module in an appropriate position, probably on the floor.  This typically adds 0.5m to your requirement.

Performance Steps

When the increasing performance of each item in a range (eg, Standard – Silver – HiRez) is being described, remember that the description is given in the context of a system setup where that level is appropriate and cost effective (see Systematic Approach). Where the performance of the entry-level product in that range is described, we are describing it in a typical ‘non-treated’ system context. Where the higher performance products are being described, we are then giving that description in the context of a system that is reasonably well provisioned with Vertex equipment throughout the rest of the system. In other words, the hypothetical system is not being hampered by major faults in other areas, which would be the limiting factor. Rather, the system is well sorted and has ample latent performance headroom to realize the gains that the next product up the range is capable of delivering.
