The Axis Voicebox EBS Extended Bass System is further evidence of designer John Reilly’s out-of-the-box thinking, made possible by decades of experience in designing award-winning loudspeakers. Read Edgar Kramer’s review here, then read about how the Voicebox EBS works here.

Well, if you are looking for a plate amplifier for your DIY active sub-bass project then you’re in luck. John has just made the one-of-a-kind EBS’ plate amp, the EBA-150, available separately.

Can’t swing the dollars for a stereo pair? No problem—build one first, then build its stereo mate later.
