Short answer: the Pitt & Giblin Superwax Mini. It ranks #7 of 15 powered floorstanding speakers by sound quality (rated 4.6/5); the Grimm Audio LS1c + SB1 ranks #9 (rated 4.4/5).
The Pitt & Giblin Superwax Mini is the more accurate option. Large active two way speakers with highly accurate, natural vocals, deep bass and both digital and analog inputs. Its measured preference score, a predictor of how neutral it sounds, is 7.59 against 5.73 for the Grimm Audio LS1c + SB1. The catch: The Mini gives up some deep-bass reach compared with the full Pitt & Giblin Superwax.
The case for the Grimm Audio LS1c + SB1: A complete active monitor system with matching subwoofers, very wide dispersion, accurate sound and low distortion. Watch for: The standard preference score is only 5.73, rising to 7.54 with an ideal subwoofer, because spinorama puts the system’s -6dB point at 45.4Hz despite the subwoofers.
Buy the Pitt & Giblin Superwax Mini. It is rated higher for sound quality than the Grimm Audio LS1c + SB1.
