Pitt & Giblin Superwax vs Grimm Audio LS1c + SB1

The Pitt & Giblin Superwax is the more accurate choice. Massive active speakers with highly accurate sound, extremely deep bass and digital and analog inputs with three voicing options. Its measured preference score, a predictor of how neutral it sounds, is 7.74 against 5.73 for the Grimm Audio LS1c + SB1. The tradeoff: The measured 2.3dB response span from 300Hz to 5kHz leaves more local midrange variation than the Pitt & Giblin Superwax Mini; a level overall slope is not a perfectly flat response.
