Tannoy VQ Net 60 and VNet 218DR

A loudspeaker and subwoofer combination that yields a four-way system for sound-reinforcement applications.
Tannoy is known the world over for its excellent studio monitors. There aren’t many studios in the world that haven’t had a pair or three at one time or another. Tannoy has turned its attention to creating sound-reinforcement loudspeakers, and among the products of its labors is the VQ Net series of active, network-linked loudspeakers with digital signal processing. These loudspeakers are intended for use in arrays or individually, and provide all the obvious benefits that self-powered loud¬speakers bring. As a live sound engineer who frequently requires powerful, high-fidelity loudspeakers that I can easily transport and quickly configure, I was excited to get my hands on these. Additionally, I have always liked Tannoy’s studio monitors, so I found myself very curious as to whether the firm could successfully translate the quality of its fine studio loudspeakers to the sound-reinforcement domain.
I evaluated a pair of VQ Net 60 loudspeakers along with a pair of VNet 218DR subwoofers, the combination of which yields a de facto four-way system: the VQ Net 60 loudspeakers are a three-way system, and the VNet 218DRs fill in the low end. Tannoy touts this loudspeaker series as a “line-array killer,” and the company is not the only loudspeaker producer in the world to extol the virtues of point-source loudspeakers. It’s unlikely that the debate over whether point-source loudspeakers can be used interchangeably with line arrays will be resolved anytime soon, despite the smart people who argue each position, but it’s clear that there are appropriate applications for both topologies. From a practical standpoint, I’d rather roll VNet loudspeakers in on their dollar boards than fly arrays from a truss, particularly for applications in small to mid-sized venues that don’t require huge amounts of SPL. On the other hand, the VQ Net series are actually capable of producing a pretty substantial amount of SPL; they’re rated at 138dB SPL continuous. And I discovered these loudspeakers to be simple to set up—although I would not recommend making this process a one-person project unless that person is a body-builder. The recommended orientation is to place the VQ Net 60 atop the subwoofer, and the heft of these loudspeakers definitely does not make for a safe one-person job.
I was otherwise pleased with the mechanisms intended to make transport and rigging easier. The dollar boards included with the VQ Net 60s are welcome, and cleverly include attached rigging hardware. The subwoofers are not intended for flying, but the VQ Net 60s can be flown with eyebolts and brackets, and they can be linked and arrayed with additional hardware. VQ Net MB and VQ Net 85DF cabinets can be combined for additional pattern control. Every loudspeaker has at least two handholds on each of its four sides. I was able to tilt a subwoofer from its performance orientation up onto its wheels by myself as a result of the placement of the handholds and the center of gravity of the cabinet. The other clever convention I discovered is the plates that cover each subwoofer’s array of connection ports. During transport and storage, these plates pop right into place with magnets to protect connections and controls.
Wiring is simple as well. AC power is provided via Speakon connectors, and audio is introduced via standard XLR inputs. These loudspeakers are telemetrically monitored and controlled via Tannoy’s network software, and these connections are made via RJ-45 Ethernet ports. I like that the network can be configured in a daisy-chain, a star network, or any combination of both topologies. With the assistance of an engineer acquaintance of mine, I was able to get the system up and running in less than half an hour, and time could be shaved from that performance with some repetition. One issue that is a little troublesome to me is that audio will not pass through the loudspeakers unless they are connected to the network and unmuted with the included software. Any computer- or network-oriented snags can be a roadblock to simply getting signal to play through the loudspeakers. It may be the case that the loudspeaker simply stores the previous mute configuration, and it’s possible to leave the loudspeakers unmuted, but I’d rather not have the potential for the loudspeakers to have been left in muted mode upon last power-down. I hope that will be addressed in future revisions.
The VQ Net 60 features a semihorn-loaded topology with two 12in. LF drivers on angle with each other, and a conical horn loaded with concentric MF and HF drivers, which provides a single coherent wavefront emanating from the throat. The MF driver has a 3.5in. coil and covers 400Hz to 7kHz, and the HF driver has a 2in. diaphragm and covers 7kHz to 22kHz. I like the fact that Tannoy put the crossover points at frequencies that are not in the middle of the human vocal range. The 60-degree conical dispersion of the MF and HF horn structure is efficient, with a directivity factor of 21.2. As I walked around to subjectively assess this directivity, I was truly impressed. The signal drops off precipitously just a few steps beyond the edge of the dispersion pattern. This means that in typical applications in which these loudspeakers are stacked on stage, performers and public speakers hear very little of FOH, even when the system is producing substantial SPL.
