Tonitro Subwoofer

Tonitro Subwoofer

The Tonitro does not have it's Latin name for thunder without cause. Being designed around a hugely respected Peerless subwoofer unit and a 300W rms amplifier built to Robson Acoustics exacting specifications, Tonitro gives exceptional performance and delivers superbly controlled low bass.

As with all of Robson Loudspeakers and in house designs, constraints on material costs and choice of drive units imparts minimally which enables our designs to fulfil ultimate performance without huge price tags. The Tonitro utilises a choice of drive unit and high current amplifier that at this price point, other manufacturers could not justify allowing the portrayal of the loudest movie effects and the most delicate of acoustic nuances to be heard.

Advanced computer technology and hours of listening tests has produced a sub woofer that will not only give added dimension to multi channel surround systems but can be designed around your existing d├ęcor and furniture.
