How would you get into the biz?

There is no good way, its a dying thing totally replaced by iphone and 10$ earbuds .

Eric, I see the real problem as the large number of other co.s with significant engineering talent and other resources already occupying the space.

maybe local boutique type market?

I have no doubt that Erik can design a top notch speaker that will compete... I think the issue lies is that as an unknown,  you have to clearly build something that is extra ordinary or a huge value that isn't normally done... To build a GREAT 2 way at a decent price will be very hard to compete with, You'll certainly sell a few, but I wouldn't plan on making it rich that way.  Just too many out there already doing it.

Find a nitche, be ready to constantly change with the whims of the market,be prepared for $ ups and downs of said markets. Loudspeakers are something everyone has and no one needs they exist to most as a equivalent of a toaster bought with as much thought.  The small small group that cares has many marketing to them at all price levels. Even if you had the worlds best loudspeaker and price on such doesn't mean you will succeed audiophiles are name brand buyers purchases made as much to impress as for sound quality.

It's exactly the same as the restaurant business -- it's something everybody can do but not do well. Speakers are just boxes with drivers with simple electronics that cookbooks can tell you how to put together. But then you have to deal with the hurdle as to why restaurants fail: What are you offering that the hundreds of other restaurants in town don't offer at the same prices? In other words, find a niche and do it better than others.
