Not sure about using it in a three way, but I used it in a two way experimental project (not my design) with a VIFA BC25 tweeter in a large ported cabinet. The bass was OK, but the overall sound was not quite there, I suspect due to my alleged efforts at crossover design.
It's also been used in the follwing project - also a two way - but it was matched with a full range VIFA TC7 and crossed at about 1000 Hz, so I guess you could regard it as a 'sort of 3 way' as people with good hearing might wish to add a tweeter. I haven't heard this, of course.
I thought this woofer was good value and although it looks the same as the Peerless 830657, it has much more Xmax. I used both of them in my test cabinet and thought they sounded very similar.
