Have your Response 2 had any maintenance? ProAc speakers of that age are all coming due for woofer replacement. For some reason refoaming is not good enough and woofer replacement is recommended at $300 each.
It is my opinion these foam surrounds are not going bad overnight rather they are slowing becoming weaker with age and gradually changing the sound. I have a feeling the aged sound is preferred by most users because it is common to see ProAc speakers with recent woofer replacement for sale. It obviously takes a lot more power to get the same bass with the new tighter surrounds.
Because of woofer foam rot and this potential for ever changing sound I have decided to stay away from speakers using this type of driver.
