It sounds like you are not getting rid of the built in crossover, just providing some controllable external crossover point and manipulate equalization. I am not sure it will improve sound unless you think the current speakers sound very bad. Problems with matching amplifiers has already been pointed out. I am not against equalization if done correctly, DEQX is as good as you can do for the money.
Bi-amping with DEQX active crossover
I am thinking about using a DEQX HDP-4 to bi-amp a pair of Wilson Watt Puppy 6's. I have agreed a price to buy a Class D Primare A34.2 amp with 150w which I could use for the woofers and then use my existing Class A mono's for the mid and tweeter. I will probably use a DEQX consultant to come and help set it up. I would be grateful for any advice and answers to the following questions.
1. Is this a good/bad idea? Wilson do not advocate bi-amping but they may have their own agenda.
2. Can anyone advise on the natural crossover for WWP's passive crossover circuit? What levels should I use for the high and low pass filters? I have emailed Wilson but they have not responded and I doubt they will release this info.
Thanks for your help..
