Short answer: the Grimani Systems Tau. It ranks #10 of 14 powered floorstanding speakers by sound quality, rated 3.6/5, at $29,000; the PMC PMC10 ranks #12, rated 3.4/5, and costs $47,500, so there is not much of a tradeoff to weigh.
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 tradeoff: Audioholics’ measurements stop at 200Hz, so it has no preference score; the rating is estimated from that data and the measured Grimani Rixos-L.
The case for the PMC PMC10: A three-way active studio main monitor with a 10” woofer in PMC’s ATL transmission-line enclosure, a 75mm soft dome midrange and a 34mm soft dome tweeter, driven by an outboard amplifier and DSP rack. Watch for: PMC’s own measurements show an uneven on-axis response for a speaker at this level, for a preference score of 4.31 that reaches 5.48 with an ideal subwoofer.
Buy the Grimani Systems Tau. It is rated higher for sound quality than the PMC PMC10 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
About the ratings: the Grimani Systems Tau’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 3.2 to 4.0, so this verdict could change once it is measured.

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.

Grimani Systems Tau: $29,000 per pair Estimated Grimani Systems eBay
Pros: 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. Grimani rates it from 35Hz to 20kHz and 110dB maximum SPL.
Cons: Audioholics’ measurements stop at 200Hz, so it has no preference score; the rating is estimated from that data and the measured Grimani Rixos-L. It is sold through custom installers rather than retail.

PMC PMC10: $47,500 per pair Sweetwater eBay
Same family: the PMC PMC12 (larger floorstanding, ranked higher, rated 3.7/5), the PMC PMC15 (larger floorstanding, ranked lower, rated 3.3/5) and the PMC PMC10-4 (larger floorstanding, ranked lower, estimated 3.3/5).
Pros: A three-way active studio main monitor with a 10” woofer in PMC’s ATL transmission-line enclosure, a 75mm soft dome midrange and a 34mm soft dome tweeter, driven by an outboard amplifier and DSP rack. PMC’s own measurements show deep bass, 32.2Hz (-3dB).
Cons: PMC’s own measurements show an uneven on-axis response for a speaker at this level, for a preference score of 4.31 that reaches 5.48 with an ideal subwoofer. The data has not been independently verified. It needs PMC’s master36 controller and amplifier rack, and it is a pro studio product sold through pro audio dealers.
