on classicspeakerpages a guy said if the cap directly across the woofer. If it's value has drifted way high (and that sometimes happens with old caps), it would prevent the woofer from getting adequate current....
the cap across bass is a 150mf & when tested it showing 177mf could that be class as high is it better to change all the caps

177 mf is not unreasonable to thwart proper operation of the woofer.
In fact, it's basically within the tolerances in manufacturing.

It's been said that the cabinet does not need to be 100% airtight.

My AR4x woofers have perforated dustcaps so they're not 100% airtight. My 3a's are as airtight as I could make them. The woofer cones slowly return when pushed in. I agree the cap isn't that far out of spec to cause the dramatic loss of bass being described. I would replace that cap though.

Just to eliminate things in the troubleshooting process, can you use / borrow a receiver and hook the speakers directly up to it with a cd player and then verify that the problem is in the speakers?

sorry for not replying quicker but been busy with work & thank's for all the reply's. update on speaker's i lowered stand's from 13" down to 6" which had better control over mid's which made them better to the ear's di try to eliminate the cause & found cd souded a little better cable's change made no diffference tryed different amps only a yamaha amp made a slight improvement & tryed two other set's of speaker found epos on stand's sounded great but sounded a little too digital to me. so went & replaced quad amplifiers with naim pre-power-hicap & speaker's souded more smooth more detailed in top end and a nice bass not over powering still need to test more been a lot of work but getting there will keep you imformed and thank's again
