The Donald McNeely Spectrum is a multi-purpose fieldhouse that is home to the SJU indoor track and field and tennis teams, as well as various intramurals. The Donald McNeely Spectrum includes a regulation sized six-lane, 200-meter indoor track, three indoor tennis courts (one doubles court and two singles courts), long jump, triple jump and pole vault pits.

In times of adverse weather, the spectrum is utilized by the football, baseball and golf teams as an alternative, indoor practice facility. The wrestling team hosts its annual North Country Open in the Spectrum every February and the Spectrum has also been host to the Minnesota Intercollegiate Athletic Conference (MIAC) Indoor Track and Field Championships.

The Spectrum is also the main intramural and club facility on campus. It hosts various intramural leagues and championships during the course of the academic year and doubles as a practice space for club sports.
