130 mm 5.25in component 2-way speaker system with a coated cellulose pulp woofer and peripheral butyl suspension. The woofer uses a generous magnet listed as 80×15 and the soft-dome tweeter features a neodymium magnet with a 20 mm CCAW voice coil.

The system includes an in-line 6 dB/octave crossover with adjustable tweeter level selectable at 0 dB or -3 dB. Designed to replace OEM 5.25in speakers, the high-efficiency 2 ohm design provides detailed output with or without an external amplifier. BLAM describes the Relax series as reflecting 25 years of development and the French Sound character.
