Why OSCA Backs This Product

If you want a set that feels “serious” the moment you pick it up, this is it. Aluminium baskets with fibreglass cones, it’s the kind of 2-way kit that makes sense when you want clean, balanced sound and solid midbass impact, without going straight to the highest tier pricing.

Reference Grade High Resolution

Advanced composite cone technology delivers extended frequency response, precise imaging, and two-dimensional soundstage that reveals every layer in your music.

A rigid aluminium chassis keeps every driver stable and controlled. The 28mm fabric dome tweeter adds smooth, refined highs, delivering sound that stays detailed and musical at any volume.
