Short answer: the ULT10. These rank #39 and #41 of 42 10-inch PA speakers, and the Delta X10’s own measured data flags it as needing a subwoofer far more urgently than the ULT10 does.
The measured gap between them is large. The ULT10 posts a 3.2 ideal-subwoofer preference score with 71Hz measured extension, itself below most other actives in this size class. The Delta X10 measures much lower still, at 1.49 preference score with bass extension only to roughly 100Hz, the weakest measured result across the whole ranking, so a subwoofer partner is effectively mandatory rather than optional.
They are also different kinds of speaker. The ULT10 is fully active, built around a custom 10-inch driver with a 2.5-inch voice coil and a WorxAudio-designed rotatable Pivot X110 horn giving a wide 110° x 50° dispersion pattern at 1,300W peak, with two XLR/TRS combo inputs and DSP built in. The Delta X10 is passive, with a titanium-diaphragm compression driver, and can run full-range or switch to bi-amp mode when paired with separate amplifiers, meaning its final sound depends heavily on the amp and processing behind it.
Build quality favors the Delta X10 on paper: 15mm birch plywood against the ULT10’s unstated cabinet weight, and 300W continuous / 1,200W peak handling that undercuts the ULT10’s amplifier only because it is passive and relies on external power.
Buy the ULT10 for active, self-contained operation with a wide rotatable horn and meaningfully deeper measured bass.
Buy the Delta X10 only if you are already running a passive rig with a dedicated subwoofer and want a budget-entry plywood cabinet to fill in with your own amplification.

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.
