Above: the binding post plate states 4 ohms or 1 ohm, which indicates this is an early model. But this change is not something that can be set with the flick of a switch, rather this requires the removal of the back plate and rewiring the cables inside.
By altering the wires it is determined whether the woofer ribbons are wired in series or in parallel, and this changes their impedance from 4 ohms to 1-ohms. Similarly, the midrange -tweeter sections are changed from series to parallel, resulting in an impedance of 3-ohms or 1-ohm.
Later Scintilla models were 1 ohm exclusively, and this is visible from the wider spacing of the slits.

Generic Info
Apogee’s second speaker after the Full Range still is one of the hardest speakers to drive properly. The early Scintillas were were configurable for a 1 or 4ohm load, the later models were 1 ohm only (from 1987 approximately). While the 4 ohm setting on the earlier models made the Speaker considerably easier to drive, according to the reviewers in doing so it lost some of it’s “magic”. According to a Stereophile review, “they sounded more dynamic, liquid, and natural in timbre when they were wired for 1-ohm. At 4-ohms, they seem to parody the colorations you normally hear – and add new ones; this can be jarring”.
Here’s how the two models differ:
- The 1 and 4 ohm model has cuts in the bass panel spaced approx ¾” apart measured vertically.
- The 1 ohm only model has cuts spaced approx 1½” apart (double the normal cut spacing)
The 1 ohm setting has been reported to kill a Krell 250a whilst trying!
Not as big as the Full Range but still they dominate a room, especially as they require considerable ‘free air’ around them so as not to sound bass heavy. The speakers are unusual as they have one midrange and four tweeter elements. The tweeter elements are arranged either side, about ½” in front and behind the mid/tweeter unit.
Still considered by some to be one of the best speakers in terms of vocal reproduction with crystal clear treble and very well extended bass, reaching a true 20Hz in test.
