pierre, I agree with you. Two Wizzys for a double bass gig would be pretty radical. Unless maybe it was an outdoor gig, or you wanted one speaker for you and the other one pointed at your bandmates. I dunno - You're right though, if I had to go that loud on DB, I probably don't want the gig.
I was thinking more of the occasional gig I get on electric bass to be honest.
For that matter, kinda like what you said, the thought of carrying one Wizzy and one Contra/Coda to a gig turns me off too.
The reason I mentioned the powered Wizzy is that my iAMP-200c Wizzy combo cannot power a traditional extension cab as I understand it. The powered Wizzy speaker is specifically designed to pair up with the iAMP-200C Wizzy combo, or with any basic preamp I believe. If I were to pair a powered Wizzy with my combo, yes it would double the power from 200 to 400 watts, as well as doubling the speaker surface area.
Yup - I think some folks are waiting for the EA NL-208. At the same time, still other people have had luck with lots of other choices for extension cabs though, like what LowNote said.
Hard to decide what to do with all these options! I for one am very grateful we can get advice from lots of folks here on TB to help steer our decisions.
I mean, how else would I be trading ideas with a bass player in France? Very cool indeed!
