Boxed features quadraphonic remixed versions of Mike Oldfield's first three albums. Oldfield later explained that instead of being true 4 channel sound, the initial quad remix of Tubular Bells, released few months after the stereo version, was a "strange fake out-of-phase system", because it was so complex a mix without automation. The quad remix of Tubular Bells on Boxed was entirely different and true 4 channel sound (later released on SACD). The Boxed-CD version still contains the SQ-encoded quad mixes and plays as normal stereo without a quad decoder. The SQ quad remix Hergest Ridge was the only version of the album available on CD (until 2010 Mercury Records reissue, Deluxe Edition), as Oldfield disliked the original vinyl mix.

The traditional hornpipe melody "The Sailor's Hornpipe", which was the finale from Tubular Bells, has an extended speech from Viv Stanshall, which is from the recording sessions at The Manor Studio (see Tubular Bells original ending).

Tubular Bells was re-mixed in quad by Phil Newell, assisted by Alan Perkins. Hergest Ridge was re-mixed in quad by Mike Oldfield. Ommadawn was re-mixed in quad by Mike Oldfield and Phil Newell.

The album cover adapts the theme of two M. C. Escher's engravings: Gallery and Other World.
