2. Introduction
Designed and engineered in a unique partnership between Tannoy and Lab.gruppen, the VXP Series
comprises a range of powered (active) loudspeakers for demanding professional and commercial sound
applications. Each incorporates acclaimed Dual Concentric™ driver technology in tandem with on-board
powering by Lab.gruppen’s IDEEA™ (IntelliDrive Energy Efficient Amplifier) module.
All VXP Series loudspeakers are designed to perform with very high efficiency and exceptionally low distortion,
even when operating near peak output levels. At the heart of VXP Series is the latest genearation of Dual
Concentric loudspeaker technology, which combines a high frequency driver and a low-mid driver on a
common axis to create a true point source for all reproduced sounds. Dual Concentric eliminates the time
alignment problems inherent with all separated driver enclosures, ensuring outstanding definition, detail and
intelligibility at all points in the listening area.
Paired with Dual Concentric driver technology is the new IDEEA powering module from Tannoy’s sister
company in Sweden, Lab.gruppen. At the heart of the IDEEA module is a patented Class D output stage
capable of sustained high power levels with very low distortion – all with near 90% efficiency. A universal
switching power supply accepts any mains voltage from 100 - 240 V (+/- 10%) at 50 Hz or 60 Hz through the
appropriate IEC cord. The power control selector supports two operational modes: in Auto mode, the system
turns on with signal present and turns off after 20 minutes of no signal input; manual mode allows the speaker
to be turned on and off as required. Also provided is a switchable 90 Hz high-pass filter for use when adding
a subwoofer. To ensure a long and trouble-free service life, IDEEA modules incorporate extensive features to
safeguard internal circuits and the driver complement.
Within the VXP Series, system designers can choose from a variety of sizes, power levels and coverage
patterns to suit particular requirements. For extended bass performance, models with the “.2” designation
augment the Dual Concentric LF driver with a second matched LF driver. The “HP” designation indicates
extended power handling capabilities, while the “Q” suffix indicates incorporation on the new Q-Centric
Waveguide (QCW™) for applications requiring an asymmetrical coverage pattern. The QCW horn can be
rotated in a matter of minutes, allowing placement of the 75 x 40 degree pattern with either horizontal or
vertical orientation.
All VXP models are enclosed in rugged birch plywood enclosures, with larger models equipped with double-
chamfered Integrip™ recessed handles for easy one- or two-handed carrying. Reflecting Tannoy and Lab.
gruppen’s common reputation for reliability, all VXP Series loudspeakers are backed by a five-year warranty.
