Amphion BaseTWO25 Stereo Bass Extension System

Stereo-Bass Erweiterungssystem, 2 Subwoofer Tower und 2x 900W Amp

Modern music is increasingly bass-intensive. To pack the maximum amount of energy into the lowest octave – with no surprises in the playback – a sound engineer needs to hear and feel throughout the whole frequency spectrum.

BaseTwo25 low-frequency extension system fits equally well in any composing, mixing, or mastering setup, where correct reproduction and appreciation of the lowest octave is critical. Amphion’s innovative approach to low-frequency monitoring provides producers, sound engineers and artists with a completely new perspective to the base.

The BaseTwo25 is a state-of-the-art monitoring solution converting any Amphion two-way studio monitor into a full-range, time and phase coherent, three-way system. These full-range towers extend all the way down to 20Hz. Each BaseTwo25 has 2 x 25 cm woofers (top) and matching 2 x 25 cm radiators (below) mounted in back to back force-canceling mode on both sides of the cabinet. The system is driven by 2 x 900W amplifier, and controlled by Amphion’s signature filtering module with a variable-level attenuator.

In addition to providing tight, tuneful bass, BaseTwo25 improves midrange clarity and increases the midrange power-handling abilities of the paired monitors. This is achieved by gradually transferring the low-end frequencies from the monitors to the base extenders.
