Thanks for sharing that video. That StagePas and QSC K always seem like viable alternatives to a bass amps. It seems that these PA's have been getting so good that at some point dedicated bass amps are going to be a matter of personal preference. If SOMEONE ELSE were to haul the StagePas to the gig and all I needed to do was show up and plug in, I'm all in.
I share the same opinion regarding the Upshot vs the older series. I like the Upshot for it's portability and there are huge benefits to having an up firing speaker. There's more of a directness and I can hear myself better. For the sake of a great overall sounding band, I am a big proponent of not having speakers aimed at the legs and feet of instrumentalists, but at their ears instead, which the Upshot solves for bassists. It's now my main go to and my main speaker because I can hear myself clearly without needing to crank it up more than necessary to the benefit of the group's sound.
The upshot doesn't sound quite as good as a Coda Series III/4, but it's a net positive. It sounds great and if I didn't have both to A/B, I likely wouldn't have known the difference. Once I'm playing, the difference is not noticeable since I'm far too busy listening and focused on the music to notice the difference in sound.
What I discovered is that the older down firing cab plus an upshot compliments each other extremely well. Adding the Upshot together with a Series III or 4 is a fantastic combination. I can hear myself clearly and the overall sound is full, round, clear and Hifi. The older series might be discontinued, but it's not obsolete.
He likes "more direct" (as most of us do). If he did the Ten2 plus the Upshot, he might have liked the overall results.
