Short answer: the GGNTKT M1 for better sound quality, the Palmer Orbit 11 for the lower price. The GGNTKT M1 ranks #35 of 48 powered bookshelf speakers at $7500. The Palmer Orbit 11 ranks #36 at $766, $6734 cheaper.
On the GGNTKT M1 side: One front and two rear firing 6.5 inch aluminum woofers cancel each other’s rearward radiation for genuine cardioid bass control, confirmed by a sound power directivity index that climbs steadily through the midrange rather than the erratic pattern typical of non cardioid designs. The catch: On axis deviation measures a comparatively rough 0.475dB average despite the excellent listening window smoothness, meaning a listener sitting dead center may notice more unevenness than the off axis figures suggest.
What the Palmer Orbit 11 gets right: True coaxial point-source layout (6.5” midrange + 1” tweeter on the same axis, flanked by dual 8” woofers in a 2.5-way configuration) plus a cardioid front baffle to reduce rear/side room reflections - genuinely differentiated pro-monitor engineering. Watch for: XLR analog and AES3 digital I/O only, no consumer RCA/TRS - this is a studio-signal-chain product, not a plug-and-play hi-fi speaker.
Buy the GGNTKT M1 if sound quality matters more than the price. Buy the Palmer Orbit 11 if the price matters more than sound quality.
If sound quality matters at all to you, skip the Palmer Orbit 11. It ranks near the bottom of the 48 powered bookshelf speakers, so look higher up the list instead.

The Two Speakers In Full
GGNTKT M1: 7500 GBP/pair Purite Audio (UK)
Pros: One front and two rear firing 6.5 inch aluminum woofers cancel each other’s rearward radiation for genuine cardioid bass control, confirmed by a sound power directivity index that climbs steadily through the midrange rather than the erratic pattern typical of non cardioid designs. Listening window smoothness measures 0.67, among the best of any speaker added to this catalog from spinorama.org’s measurement set, and the measured extension reaches 33.8Hz, deeper than most speakers in this class.
Cons: On axis deviation measures a comparatively rough 0.475dB average despite the excellent listening window smoothness, meaning a listener sitting dead center may notice more unevenness than the off axis figures suggest. At £7,500/pair it is one of the most expensive speakers in this catalog, sold through a single UK dealer with no direct online checkout. The electronics live in a separate outboard enclosure connected by cable rather than being built into the cabinet, adding setup complexity most active monitors avoid.

Palmer Orbit 11: $766 Thomann
Pros: True coaxial point-source layout (6.5” midrange + 1” tweeter on the same axis, flanked by dual 8” woofers in a 2.5-way configuration) plus a cardioid front baffle to reduce rear/side room reflections - genuinely differentiated pro-monitor engineering. Deepest bass extension of the entire batch by a wide margin: 27.8Hz at -3dB / 21.5Hz at -10dB, backed by tri-amped Class-D power (1000W peak / 400W RMS combined) and linear-phase FIR DSP running at 96kHz/24-bit. Highest predicted in-room preference score of this batch (pref_score 5.3).
Cons: XLR analog and AES3 digital I/O only, no consumer RCA/TRS - this is a studio-signal-chain product, not a plug-and-play hi-fi speaker. At 13.9kg and roughly 22 x 29 x 29cm each, it’s heavy and deep for shelf placement, effectively requiring a stand or wall/desk mount. Sold individually at $766/unit ($1,532/pair).
