Short answer: the Pitt & Giblin Superwax Mini. It ranks #6 of 14 powered floorstanding speakers by sound quality (rated 4.6/5); the Grimani Systems Tau ranks #10 (rated 3.6/5).
The Pitt & Giblin Superwax Mini is the better-sounding choice. The published DSP-adjusted manufacturer measurement shows a 1.2dB response span from 300Hz to 5kHz and a 8.60 ideal-subwoofer preference score, supporting natural vocal balance. Watch for: The Mini gives up some deep-bass reach compared with the full Pitt & Giblin Superwax.
The case for the Grimani Systems Tau: A slim active tower with two 6.5” woofers and a 1” compression driver in Grimani’s Conic Section Array waveguide, driven by two 600W amplifiers with built-in DSP crossover and EQ. The catch: Audioholics’ measurements stop at 200Hz, so it has no preference score; the rating is estimated from that data and the measured Grimani Rixos-L.
Buy the Pitt & Giblin Superwax Mini. It is rated higher for sound quality than the Grimani Systems Tau.
Worth knowing: the Grimani Systems Tau has not been measured yet. Its rating is estimated from related models, with a likely range of 3.2 to 4.0, so treat this verdict as provisional.

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. The two were measured by different sources, so small differences, especially in the bass, can come from the measurement setup rather than the speakers.

The Two Speakers In Full
Pitt & Giblin Superwax Mini: A$15,175 per pair Pitt & Giblin eBay
Same family: the Pitt & Giblin Superwax (larger floorstanding, ranked higher, rated 4.6/5).
Pros: The published DSP-adjusted manufacturer measurement shows a 1.2dB response span from 300Hz to 5kHz and a 8.60 ideal-subwoofer preference score, supporting natural vocal balance. Bass reaches 30.9Hz at -3dB. The 15-inch woofer, bronze waveguide and built-in amplification provide a substantial two-way system with both digital and analog connections.
Cons: The Mini gives up some deep-bass reach compared with the full Pitt & Giblin Superwax. Its low cabinet height makes the supplied tilt feet and listening position important. At 40kg per speaker and 460mm wide, it is still a large installation. The quoted response describes the measured DSP tuning; alternate voicing profiles change the balance.
