Bill, more than one manufacturer went through several iterations of Neo speakers for bass, before feeling like the technology was far enough along to maintain a supportable warranty rate. As usual, for guitars or other apps, the physics involved were small enough not to matter.
There seemed to have been quite a bit of work to get Neos for bass to that point, and you only see them in cabs for a 200-400 watt range, a lot of combo amps.
No, I don't think your house will burn down. But it's interesting to read Andy's explanantion about how long it's taken him to find something that would work for his application. And like most things bass, when I hear that EAW or TurboSound or the reinforcement guys have adopted versions for live sound work, then I'll feel a little more satisfied that it's a maturing technology. But that's just me. I would not be ready to run an F2B and a big QSC into a small stack of Neo bins.
Edwin, for me the Wizzer cabs speakers are just as bogus in bass cabs as they were in car stereo or home audio. And to me, EA understandably has tried to take a turn to a more mainstream business profile to make more income, and that's fine. But in no way for me does their new stuff replace the startling performance of those little transmission line cabs.
I guess that's all the wildly unsupportable BS opinion I have to spew about this . . .
