Short answer: the GGNTKT M3. It ranks #3 of 15 powered floorstanding speakers by sound quality (rated 4.7/5); the Pitt & Giblin Superwax ranks #6 (rated 4.6/5).
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 6.61 for the GGNTKT M3. Watch for: 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.
The case for the GGNTKT M3: Huge active floorstanding speakers with exceptionally even, accurate sound and cardioid bass that copes well near a wall. The catch: Measured -3dB extension of 35.5Hz is useful but does not match the deepest-reaching towers here.
Buy the GGNTKT M3. It is rated higher for sound quality than the Pitt & Giblin Superwax.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared.
