Product Overview

Calling all bass lovers in rooms of all sizes: Alta Audio’s IO is unimposing in physical size, but presents a large and wide sonic image with extraordinary bass.

Its diminutive footprint belies the wallop of its sonic presentation; intimate details of a live performance are presented as is, with complete neutrality and three-dimensional imaging associated with the finest concert halls.

An Audiophile Perspective

The IO was created using the same XTL* Bass (patent pending) transmission line and DampHard cabinet construction on the faceplate as Alta Audio’s acclaimed Celesta FRM-2M speaker. Yet it does so at a price that is within reach of music lovers at every level—from audiophiles to casual listeners.

*Extended Transmission Line—Alta Audio’s proprietary technology that applies sonic geometry to tune speaker cabinets as if they are musical instruments, delivering an accurate, fast, and powerful low frequency response.
