Short answer: the KV2 Audio ESR212. It ranks #11 of 50 12-inch pa speakers by sound quality (rated 4.2/5); the RCF ART 912-A ranks #12 (rated 4.1/5).
The case for the KV2 Audio ESR212: Vendor Spinorama data shows very deep bass for a 12-inch class box, about 40Hz (-3dB) with an ideal-subwoofer extension of 36Hz, and a standalone preference score of 4.94. The tradeoff: The dual-woofer, 3-way cabinet is bulkier than a conventional 12-inch top.
Why pick the RCF ART 912-A: A current, widely stocked 12-inch RCF with 130dB claimed output, 100° x 60° coverage and the same FiRPHASE/Bass Motion Control platform used higher in the ART 9 line. Watch for: The available low-quality manufacturer directivity data has no computed preference score, limiting confidence in cross-brand tonal comparisons.

The Two Speakers In Full
KV2 Audio ESR212 eBay
Pros: Vendor Spinorama data shows very deep bass for a 12-inch class box, about 40Hz (-3dB) with an ideal-subwoofer extension of 36Hz, and a standalone preference score of 4.94. Dual 12-inch woofers plus a dedicated 6-inch midrange give 129dB continuous and 135dB peak output, which lets one cabinet handle full-range music without a subwoofer. Measured bass extension of 40Hz (-3dB).
Cons: The dual-woofer, 3-way cabinet is bulkier than a conventional 12-inch top. Listening-window narrow-band deviation is 0.436 and the vertical coverage is very narrow, so aiming matters. Pricing is quoted by dealers and is high.

Pros: A current, widely stocked 12-inch RCF with 130dB claimed output, 100° x 60° coverage and the same FiRPHASE/Bass Motion Control platform used higher in the ART 9 line. It is a straightforward choice for users who value simple setup over menu-heavy DSP.
Cons: The available low-quality manufacturer directivity data has no computed preference score, limiting confidence in cross-brand tonal comparisons. It has only basic rear-panel presets and no wireless control or Bluetooth audio.
