Final Audio Model 12+

Alpha Audio found a remarkably generous amount of low-frequency energy for an electrostatic speaker, describing its roughly 50Hz reach as very respectable. It handles many musical genres well, though the reviewer is clear that it does not offer the bottomless deep-bass weight some listeners expect.

Reviewers describe the Model 12 as coherent and controlled across the spectrum, with a calm, revealing presentation. There is no detailed discussion of vocal timbre or the crossover region specifically, but the reported sense of insight and seamlessness is encouraging.

Alpha Audio reports more high-frequency information alongside more coherent behaviour across the full frequency range. The review portrays the treble as resolving and integrated rather than sharp or disconnected from the rest of the presentation.

This is the standout strength in the reviews: voices and instruments are presented at convincing life size, with substantial width, depth and image height. The presentation is said to detach completely from the speakers, while image stability contributes strongly to its relaxed, immersive quality.

The reviewer repeatedly praises the ease and effortlessness with which the Model 12 reproduces music, calling the result highly addictive. There is little direct discussion of large-scale slam or peak-volume headroom, so its performance with the most demanding dynamic material is less clearly documented.

Alpha Audio highlights the redesigned construction and robust PMMA and Teonex materials, expecting the speakers to operate for decades without maintenance. The panels are also notably light and easy to reposition, a practical advantage when careful placement is required.

At $12,999, the Model 12+ occupies a serious high-end price class. Neither available review directly compares its value with competing speakers or offers a clear verdict on whether its performance justifies the asking price.
