Hi been looking for a sub for my dining room to compliment a pair of epos els 303 floorstanding speakers.. using my old denon avr1803 amp. Been looking for second hand sub £100-£150 but not had any luck. Room mainly used when have friends over for music but have my old plasma on wall as well so would like it for movies too. Been tempted on bk gemini recently as only little over my budget,, how good is it?? That would be about the max i could stretch to for sub.. are there any better options? advice really would be appreciated.
