MARSHALL CHOONG AUDIO audiophile loudspeakers

20 -130Hz
91dB sensitivity
Aluminium cone subwoofer

The benefits of dipole bass are not restricted to our own systems but can enhance even the humblest of main speakers.

The pair of Trueno 38s cross over electronically at 130Hz to the main system at 36dB/octave.

Gain matching between the main speakers and Trueno ensures almost universal compatibility.

TRUENO 38 uses a 380mm aluminium driver. This driver is truly long throw, with ±23mm Xmax, necessary to move sufficient air for realistic bass.

A second stereo amplifier of 100 - 300W RMS is required. The two Trueno bass units can also be powered from a mono bass amplifier of 200 - 500W RMS: in the latter configuration, the electronic crossover sums the bass output.
