The future of loudspeaker design is now available with the new Hologram Series. Box speakers are finally obsolete.  The latest research into open-baffle loudspeaker technology has yielded a beautifully natural and transparent sounding loudspeaker in a compact, plug and play design. All Analog - no DSP required.The Hologram's precision response and musical character establishes a new paradigm in listener involvement. Even at very low listening levels the M4 maintain their dynamic engagement. Hologram's Controlled Dispersion System greatly reduces room interaction, allowing consistent results in most any room environment.
