  We consider the possibility that the soft supersymmetry-breaking parameters
m_{1/2} and m_0 of the MSSM are universal at some scale M_{in} below the
supersymmetric grand unification scale M_{GUT}, as might occur in scenarios
where either the primordial supersymmetry-breaking mechanism or its
communication to the observable sector involve a dynamical scale below M_{GUT}.
We analyze the (m_{1/2}, m_0) planes of such sub-GUT CMSSM models, noting the
dependences of phenomenological, experimental and cosmological constraints on
M_{in}. In particular, we find that the coannihilation, focus-point and
rapid-annihilation funnel regions of the GUT-scale CMSSM approach and merge
when M_{in} \sim 10^{12} GeV. We discuss sparticle spectra and the possible
sensitivity of LHC measurements to the value of M_{in}.
