A demo with a dual recto.
The speaker is very different from a c90. Way more crunch in the mids and a much more even tone. Keep in mind it is basically a 'high power' version of a G12H 30 so it has some of those tonal characteristics. I'd say it has a high end sparkle, a good grunt / kick in the lows, and a really even frequency taper throughout the range of the speaker. It really does a sort of chainsaw type modern drive tone which is honestly very impressive. I would not say the speaker is iconic; rather it is a unique, new, and very attractive tone. Just keep in mind it is something different and I think there would be the potential to hate it as much as to love it. Personally, I'd DEFINITELY run two of them with my Recto if I had space and $$$s to afford another cab for it. As for the Electra Dyne, it has the potential to be a winning combination but I honestly have not heard it so I can't comment. The sound clip should at least give an idea of what they are about.
