I have heard the Fresco and liked it a lot. It's a 3-way speaker, while the Vignette is a 2-way. The Vignette is less expensive and uses a tweeter unit similar (possibly identical) to your Montages. The crossover freq is similar as well. That could help them sound alike and thus blend well. I think the Fresco uses the same tweeter as the Vignette, but it uses a thin film design for the midrange unit as well. Crossover freqs are different than Vignette or Montage, which makes sense for a 3-way design. I think the woofers in the Fresco and Vignette are identical, but the Vignette runs the woofers farther up into the midrange because it lacks a separate midrange driver.
The Fresco has a contour switch to tune the frequency response to on-wall or off-wall mounting, but I don't think the Vignette has this feature. This could matter if you plan to wall-mount the speaker.
