Well, oh crap! from me too. I really want to try the Bass Array cab. I thought I had the cab side sorted, and to some extent I have. The One 10 is the perfect practice and small gig speaker for me. It works really well with the Magellan and adds some nice colour at low volumes for an old school sound. But...
I am going to start playing upright again soon and I'm not sure the One 10s will cut it. The old-school colour I like for home and rehearsal use might work against what is needed on a gig. I wish I could be more certain about this, but I have some issues with the way our band PA is being used and these must be sorted before I can be sure about "my" sound. But that is another line of discussion.
So here is my issue. I gigged very successfully with my previous big band using a Shuttle 6.2 12T combo * (no PA issues as I did not use it). It had more than enough headroom, and a flatter response than the Streamliner, and this flat response suited my BSX EUB. So my line of thinking is that the Magellan head into a Bass Array 12-3 would be even better, with more mids and an escape from tweeters which I have never liked much in bass cabs. Now here is the but: everyone seems to be talking about using 2 or 3 of these cabs to get a great sound. How far am I going to get with just one? Apart from the expense, I just do not have the storage space or domestic agreement to keep adding to my set of options. One cab would have enough volume for the big band, extrapolating from the Shuttle experience, but would it have the dispersion or great sound that everyone is raving about?
* I only sold this because I stopped gigging for a while. A great little combo that never let me down, although sometimes it needed, and I used, a second GB speaker.
