Short answer: the AsciLab C8C on measured bass extension, the Palmer Orbit 11 for a studio signal chain. The C8C’s dual opposed 8-inch side-firing subwoofers deliver true cardioid bass control and the deepest low frequency extension of any speaker in this batch, measured to 23.4Hz at -6dB with a listening window smoothness score of 0.75, both near the top of everything on spinorama.org, though its bass alignment Q (2.13) is peaky and suggests boominess near the port tuning frequency. The Orbit 11 offers a true coaxial point-source layout plus a cardioid front baffle to reduce rear and side room reflections, but it has XLR analog and AES3 digital I/O only, with no consumer RCA or TRS.
Buy the AsciLab C8C. It is rated higher for sound quality than the Palmer Orbit 11.

The Two Speakers In Full
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.

AsciLab C8C: €5799 per pair Audiophonics eBay
Pros: ASR’s revised measurement combines an 8.48 ideal-subwoofer preference score with a 1.7dB response span from 300Hz to 5kHz, supporting highly even vocal and instrumental balance. Bass reaches 30.8Hz at -3dB and 23.4Hz at -6dB, giving substantial low-end reach without an added subwoofer. Measured bass extension of 30.8Hz (-3dB).
Cons: The result applies to the revised measured configuration; confirm that the speaker’s tuning matches it. Each cabinet weighs about 27.5kg and needs a substantial stand. Deep extension and excellent tonality do not guarantee unlimited bass output or eliminate the need to adjust placement. The fitted bass-alignment Q of 2.13 is on the peaky side, so bass may sound boomy near the tuning frequency without EQ.
