Highlights & Key Technologies

Powered & Passive Hybrid Configuration
Obelisk is offered as a powered and passive hybrid, providing remarkable placement flexibility within the 50th Anniversary Series lineup. This configuration delivers tower performance with statement-level presence — authority, openness, and lifelike scale — in a design intended to integrate into the listening environment with a stealth approach.

Driver Complement
Obelisk pairs a 1" x 4.72" Reference AMT tweeter with a premium 10" planar magnetic mid-transducer for openness and detail through the critical midband. Bass is handled by two RBH 8" cast aluminum basket, aluminum cone long-throw woofers in an opposing configuration, available with silver or black anodized cones. The result is a full-range design capable of 14Hz in-room response.

Cabinet, Grille & Plinth
The cabinet is constructed from High Density Fiberboard (HDF) with an acrylic polymer bezel, finished in satin black or white paint. A 1/2" HDF magnetic grille (black or white fabric) is included. The speaker is supported by spiked feet in a plinth for a minimalistic footprint that integrates discreetly into the room.
