No.Meyer sound actually makes a monitor speaker specifically for FRFR guitar?
That's the whole point. "FRFR" is a bunch of marketing BS. There is NO DIFFERENCE between a "FRFR" cabinet and a standard PA main/monitor cabinet.
For a modeller to sound as it should when using internal cab/power amp modelling, you need the most accurate reproduction you can get. The easiest way to achieve this is to use a high quality PA cabinet. The Meyer is one of the best on the market (similar to the JBL touring gear), so it does very well with modellers and profilers, and gets mentioned because one of the manufacturers uses it for public demos. The better the monitor cabinet you use, the more your sound will match what you will hear in FOH or recorded - which is the point of both a monitor and a guitar cabinet. The goal is for the monitor to NOT color or change the sound, but to reproduce the signal it is sent as accurately as possible.
The HR/Alto is one of the cheapest, poorest performing monitor cabinets on the market, yet they have successfully convinced guitar community that it is somehow "designed for guitar" by calling it "FRFR" and marketing it with a modeller.
PT Barnum was right, and the Headrush/Alto monitor is a great example.
