Avantgarde Acoustics ZERO TA Floorstanding speakers

Superb pair of these wonderful semi active speakers. I beleive these date from 2018. They are in superb condition. Avantgarde didn't reinvent the wheel for its own sake - the basic cabinet design remains the same and that constrained the designer to using similar Avantgarde designed and built 25mm and 125mm dome drivers (sitting in their respective 77x130mm treble and 190x400mm mid-bass horns), and a long-throw 300mm pistonic drivers for the bass. These are not the same drivers throughout, however, as they feature ferrite magnets, in part to enable a greater than 104dB efficiency and a very untroubling eight Ohm load.

The'TA' part is a custom-designed 500W amplifier, complete with user-configurable DSP, to control the subwoofer module. You can control gain, delay time, high pass and low pass filtration, and parametric equalisation from the comfort of your laptop screen.

You' is very probably a code-word for'a skilled installer', because the propensity to play loudspeaker designer and develop your own bass crossover is only matched by how much of a complete low-frequency hash you could make of things by mashing these controls at random. The installation is fairly comprehensive - not in a'move two microns to the right and the sound falls apart' way, but in a step-by-step series of placement and signal-processing steps that optimise the loudspeaker to the room. The whole DSP and amplifier section can be turned off at the flick of a 12V trigger, but it's not a good idea unless you like your music bass-free.
