looking for tight powerful bass: Mirage or Deftech

they compare as an ant with an elephant...:-)
if you want something OK in-between, I'd choose from Paradigm or PSB.

Well a key to bass is how the amp controls the woofer. I had the 3si 12 years ago. A pretty nice speaker in its time. Ants and elephants ain't that far off.(First group to second group)--- Maybe a sub to keep the bass request intact and the dollar spending in control.??

Out of those speakers listed, which one is a better one to get(used). The budget is 3k. Thanks.

Totem Forrest is the World Champ in the budget you list.

How is the Totem Forrest compared to Genesis G500? I would guess these are different animal compared to DefTech7000 right?

Thanks.
