not yet i dont have mesurement hardware , but it might be a bit tricky since i use 2 sets of speakers - 1st set - seas ca18rnx woofer , peerless mids and epos tweeter , 2nd set - visaton gf200 , same peerless mids and fountek cd1 tweeter

the dynavox amp feeds the tweeters , the ca740a the mids and the delta290 the woofers , the subs are active

probably im not looking for a flat frequency response anyway and my room is very difficult room to work with since the walls have no acoustic treatment cause the wife doesn want it

i feed the cd player via optical and pc analog

my main problem is that i get some frequencys on voices and guitars reverberating in the room , problem is minimized if i cross from woofer too mid at 600 insted of 800hz but that might make mids sound too small (like coming from a little speaker)
