hi all, first of all, its great to see so many audio enthusiasts on here...and i hope to find knowledge instead of the tired old BS u get in stores!! lol.. here we go i'm running the Acoustic Energy Aelite 5.1 Set up. They're running from a Denon 3803 amp. I get decent sound from them but have the following question THe sub for these aelites is woeful...very very limited...could anybody recommend a sub that can give more depth and keep the bass tight and accurate , in this system? anything up to £400-500.. thanks in advance..
