I wonder what the company that has this as a current production model would have to say about cloning their products?

FWIW The company in question doesn't just make good boxes, it's the system working together that makes the difference. Some of us payed the price to play with the real deal system, and you will not get that with just the sub box. Have fun with it.

Whatever they might say, I doubt I'd understand it!!!

On a more serious note, there is absolutely nothing illegal/wrong with cloning another product.  It gets illegal if you try to sell and market the product.  Make a minor change or two and it's legal again - but this site isn't for lawyers anyway.

There's not that much DSP trickery in a sub box - contrary to what marketing departments might have you believe.  It might take some tweaking to integrate with the tops of my choice, but outside of that - good bass is good bass.  No phase plug witchery or anything like that to worry about.  I'm not sure where I implied that a single sub clone would give me their full system.

In most instances yes, but not in this case.

This is a bandpass subwoofer. You will need substantial EQ, contrary to what you may believe. Regardless of what I think about copying a major manufacturer's work, at least understand what you've built.

EQ doesn't mean DSP trickery.  Pretty sure we can all tweak EQ for what we want, and I'm working on phase traces for the originals.

What other kind of DSP trickery is available in your average processor? Nothing you can do in there with delay, anyway, which leaves you EQ, high/low pass, and limiting.

That's what I'm trying to say.  I'd never try to clone a 2 or 3 way box due to the difficulties of driver integration, time/phase alignment, etc.  With a standard subwoofer (non-csa, symmetrical design) it's just EQ.  I probably won't be able to get %100 exact but I'll be able to get close enough for my liking.

How do you find that they work in large numbers?  Your website lists that you have 8 "d&b B2 clones" with a link to the d&b website.

I would think there is some sort of infringement in that regard.  It is one thing to call a copy your own model number, but when mentioning the particular model they are copied after and linking to THEIR website, surely something is "illegal" in some regards.
