Short answer: the Palmer Orbit 11. Both are rated 4.2/5 for sound quality (#61 and #68 of 118 powered bookshelf speakers), and the Palmer Orbit 11 costs $1,532 against $1,598 for the HEDD Type 07 A-Core, so with nothing between them on sound quality, price settles it.
What the HEDD Type 07 A-Core does well: The larger A-Core monitor, pairing HEDD’s Air Motion Transformer tweeter with a 7” honeycomb-sandwich woofer and two 100W Class D amplifiers. The catch: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured HEDD Type 05 A-CORE.
What the Palmer Orbit 11 does well: A 27.8Hz measured -3dB point provides genuinely deep standalone bass. The catch: Its 7.10 ideal-subwoofer score is more modest than the narrow midrange span alone suggests; response outside that band and off-axis behavior also matter.
Buy the Palmer Orbit 11. Both are rated the same for sound quality, and it costs $66 less than the HEDD Type 07 A-Core.
About the ratings: the HEDD Type 07 A-Core’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 3.9 to 4.5, so this verdict could change once it is measured.

HEDD Type 07 A-Core: $1,598 per pair Estimated B&H Photo Video eBay
Same family: the HEDD Type 05 A-CORE (smaller bookshelf, rated 4.2/5).
Pros: The larger A-Core monitor, pairing HEDD’s Air Motion Transformer tweeter with a 7” honeycomb-sandwich woofer and two 100W Class D amplifiers. The crossover is fully analog, so there is no added conversion or DSP latency between source and speaker. The 7” woofer gives it more bass reach and output than the HEDD Type 05 A-CORE, and it accepts balanced XLR and unbalanced RCA.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured HEDD Type 05 A-CORE. The analog design drops the DSP room correction of HEDD’s MK2 models, leaving only basic tone switches.

Palmer Orbit 11: $1,532 per pair Thomann eBay
Pros: A 27.8Hz measured -3dB point provides genuinely deep standalone bass. The 1.8dB response span from 300Hz to 5kHz supports even mids, and the coaxial arrangement offers a compact acoustic source for nearfield listening. A cardioid front baffle reduces rear and side room reflections. Measured bass extension of 27.8Hz (-3dB).
Cons: Its 7.10 ideal-subwoofer score is more modest than the narrow midrange span alone suggests; response outside that band and off-axis behavior also matter. Deep-bass extension does not prove high-level headroom. Studio-oriented connections and setup are less convenient than an all-in-one consumer pair. It has XLR analog and AES3 digital connections only, with no RCA or TRS.
