I have an Acoustic Energy Evo 3, centre and compacts surround system with a Yammy RXV1500 amp. No sub. i have recently decided i am lacking bass in the films department (i am happy in pure direct stereo with music). so i am thinking of a sub woofer. Now i will be living in a new build 2 bed terrace in a couple of months (thanks to the now ex wife for the need to sell big house and buy small house!) so am in a quandry. I was always happy with the 3 way Evos giving enough bass, but as i said think i ought to add to it now. But i dont want to fall out with my new neighbours and space is very definitley an issue. Any ideas ? i would like to keep the cost to as little as possible! I was looking at Kef PSW1000 or Mordaunt Short MS309.
