AsciLab BX8C
Cardioid bass module for the C8C, down to 28 Hz.
The BX8C sits under the C8C and takes over the lowest octaves: four 8" aluminium woofers and 2 × 250 W per module, with directivity control down into the bass. Together they reach 28 Hz, with up to 9 dB more headroom between 20 and 200 Hz. It is designed for the C8C only.
CHF 5'450 per pair
Incl. import & VAT
Delivery quoted separately, or free pickup in Lutry by appointment.
Requires a pair of C8C. As a set with the C8C: CHF 9'950.

What it solves
Engineered to deliver accurate sound in real rooms, not just anechoic chambers.
Down to 28 Hz with the C8C
Four woofers share the work, so each one moves less: deeper bass, more headroom and less distortion at high levels.
Fewer room problems
Controlling directivity in the bass reduces the influence of the front and rear walls and of room modes, so the bass is more consistent from room to room and setup is easier.
Three operating modes
Max SPL, Standard Cardioid and Extended Cardioid modes trade maximum output against directivity control, to suit your room.
