This statement about a compromise for WAF is wrong. WE went active on the bottom end for several performance advantages. One, it allows us to match woofer and amp parameters exactly, second, It allows us to shrink cabinet volumes to relieve possible ringing caused by large cabinet walls. Third it allows us to build in some room adjustment capabilities you can't do passively and the room interaction is one of the biggest negatives affecting system performance. Fourth, an improvement in efficiency, allowing greater flexibility in choosing your partnering electronics.
As to hearing the character of your amp, by using high level inputs, your amp defines the fidelity of the bottom end. it works that way for REL woofers, why doesn't it for us?
Of course WAF is helped by all this. Sales are/where multiples of the fine Prodigy so that success has allowed us to be constantly working on a much wider variety of goods and resources that allows us to bring multiple technologies to bear at fair pricing. Check out the fantastic review on the Summit by Noel Keywood out of England in February, the very recent review on Montis/Stage on Home Theater Shack for a reviewers take on being active. yes, the next wave is focused on the high end over the next year or so I hope all will be happy over the next several months.
